In today’s article, we will learn about its main function and the importance of this key element in the timing chain system. 

What does the timing chain tensioner do?

We find two types of chain tensioner: hydraulic tensioner and mechanical chain tensioner.

The tensioner ensures the correct and necessary tension of the timing chain that surrounds the crankshaft sprocket and the camshaft sprocket. It exerts full control, making the chain run smoothly, preventing it from rattling and coming off the sprockets. In addition, it protects other elements such as alternators or water pumps against failure.

On vehicles equipped with a timing chain, we can find the tensioner in the cylinder block. When the chain is driven, the tensioner provides the necessary tension and can absorb shock and vibration of the chain, which means that it also improves its resistance to wear. Therefore, it is a vital component in the timing chain system.

What signals timing chain tensioner damage?

Is a fact that chains will stretch due to use and over time. Wear and tear cause increase of vibration and besides causes wear on other components such as the chain tensioner.

There are some signals that can warn of a tensioner malfunction and, as such and as further explained below, will advise the user of the presence of a failing timing chain system so that they can take appropriate action.

• Rattling noise from vehicle engine.
• Loss of engine power.
• Problems when starting.

As we can see, if timing is not synchronized as it should, this will cause a series of problems related to the engine, even becoming catastrophic.

Normally, any abnormality related to the chain drive can be detected by a rattling noise. Chain tensioners that have suffered a lot of wear can be heard in some cases because the chain makes this sound.

How to prevent chain tensioner damage and avoid costly repairs

As we all know, it’s easier to stop something happening in the first place than to repair the damage after it has happened. For that, at DOLZ we always recommend acting preventively to avoid possible damage caused by any breakdown.

Preventive maintenance will save you from potential serious engine damage as well as costly repairs.

It is important to be attentive to the symptoms of wear and tear that we have discussed previously. If any of these signs happen, check with your trusted dealer as soon as possible.

When replacing a component of your vehicle’s engine, at Dolz we always recommend a practice that will optimize the system life: replace all the associated parts with that component. By doing this, the condition of the timing components is consistent so the overall performance will be optimized.

When does a timing chain get damaged?

Unless there is a specific fault, the timing chain should be replaced between 80,000 and 120,000 miles. Chain problems are frequent in automobiles with increasing mileage. If you’re driving an older car or one with a lot of miles on it, keep an eye out for signs that the timing chain is failing. Because the timing chain might break and require replacement, it’s critical to be able to spot the symptoms and have it serviced before it completely fails.

Timing chain replacement: Warning signs

Timing belts must be replaced on a regular basis, but timing chains do not. There’s no reason to alter the timing chain unless it’s damaged, strained, or otherwise affected. If there is a problem with the timing chain, your car will most likely have one or more issues.

The following are signs of a faulty timing chain:

• Starting the vehicle is difficult.
• Noise in the timing chain.
• Check engine light illuminated.
• Engine misfires and sluggishness.
• When the engine is idling, it vibrates or shakes.
• The engine will not start.

There’s a chance you’ll notice a noise coming from the timing chain cover region. A loose timing chain, which could be caused by a malfunctioning timing chain tensioner, guide, or other faults, is frequently the source of this noise. If you overlook the early warning signs, more significant problems will develop; therefore, make sure to inspect the timing chain as soon as you notice a noise coming from its mounting place.

Keep reading: The different timing chain systems

Rattling noise during start and idle

The rattling or clattering sound produced by the stretched chain may also become annoying. With the hood open, this sound will be audible, and it will change with engine speed. A broken timing chain may hop around on the crank and camshaft gears, generating rattling and knocking noises from the front of the engine, or it may hit the timing chain cover. A broken timing chain will allow the valves to come into contact with the pistons in severe failures on some engine models, resulting in very loud knocking and banging noises, catastrophic engine failure, and damage to the valves and pistons.

Broken plastic timing guide and metal shaving

Small metal parts can break off your timing chain and end up in the oil pan if it’s worn out. If your mechanic notices little pieces of metal inside the oil as it is drained or in the filter when you get your oil changed, it could signify your timing chain is starting to fail. However, there are a variety of other issues that might result in metal shavings in the oil. If you discover metal in your oil, contact your manufacturer or service provider as soon as possible for an examination, precise diagnosis, and suitable repair.

Lack of power

Because the valves are not opening and shutting at the proper times, a timing chain that has stretched sufficiently to skip some teeth on the sprocket will not allow the combustion chambers to pull in the necessary quantity of fuel and air mixture. This results in a considerable loss of power and reduces the engine’s responsiveness to accelerator pedal input.

Timing related codes

By controlling when the intake and exhaust valves open and close, the variable valve timing system improves fuel economy and engine performance. The ECM adjusts the camshaft(s) through the use of oil control valves, commonly known as VVT Variable Valve Timing control and solenoid valves.

The drivability of your car is greatly impacted by timing-related codes. Increased engine stalling, rough engine idle, decreased fuel economy, and rattling/knocking noises from the engine are the most typical issues. Continuing to drive the car in this situation could result in serious damage to several internal engine components.

The Bottom Line

The timing chain is an essential component of any engine, and your car would be useless without it. If your timing chain breaks while you’re driving, your vehicle’s engine is likely to suffer catastrophic damage. If you detect any of the danger signals described above, the best way to avoid major engine damage is to have your timing chain replaced by a skilled mechanic. You may save thousands of dollars and considerably extend the life of your engine by being proactive and aware.

At Industrias Dolz we have developed a new range of timing chain kits; they are much quieter and promote longer transmission life. In addition, they do not require scheduled maintenance.

Read on to find out everything you need to know about your timing chain system and how to replace it.

When and why replace a vehicle’s timing chain?

Timing chains, with their slimmer width, are more durable than timing belts, so they don’t require scheduled maintenance. While it is true that, over time, the timing chain can elongate, the chain tensioner may fail, or there may be other factors that lead to poor lubrication and deterioration of the timing chain.

How does a chain tensioner work? The chain tensioner is a crucial component that ensures the correct operation of the timing chain by maintaining proper tension. It uses hydraulic or spring-loaded pressure to prevent slack in the chain, avoiding premature wear or misalignment. A failing tensioner can lead to a loose or stretched chain, which might cause severe engine damage.

Timing chain problems are associated usually arise with high mileages. However, on some occasions, these tend to stretch or break over time. If a vehicle is exhibiting poor engine performance, it is having trouble to start, it is suffering from overheating, it is experiencing noises or vibration, or it is displaying a check engine light, it is most probable that you have to replace the timing chain immediately.

Things you need to replace a timing chain

Timing chain installation requires the right tools, a service manual specific to the engine’s model and a degree of mechanical know-how. Because it is a major job, the risk of performing it incorrectly could trigger irreversible consequences for the engine.

Timing chain kits are the safest way to ensure best timing chain installation practices. By replacing together all intrinsic components, timing chain replacement costs are significantly reduced while results are highly enhanced.

Installing a Timing Chain kit step by step

Step 1: Consult the owner’s manual

• First of all, locate the timing chain of the vehicle and verify the engine model, making sure that the timing system houses a timing chain rather than a timing belt.
• Rely on the owner’s manual to locate and identify the different engine parts and numbers, such as the firing order.

Step 2: Prepare the engine

• Make sure that the engine has cooled down and that it is no longer plugged in the batteries.
• If necessary, clean the engine with the use of the right degreaser and make sure that the workplace is adequate and that it offers safe conditions.
• Drain the vehicle’s oil and coolant and remove coolant hoses and other components that restrict access to the chain cover.

Step 3: Remove the timing chain cover

• Remove the timing chain cover by unbolting it from the engine block. When doing this, don’t neglect the bolts, they may each be different lengths, so you will need to know which bolt goes where on the cover.
• Remove the crankshaft pulley, loosen the camshaft sprocket, and then remove the chain tensioner. This will expose the guides, sprockets, and chain for a better access.

Step 4: Remove the timing chain

• Get the engine to top dead center and use a ratchet or wrench to remove the timing chain by sliding it off the gears.
• To do this, align the shiny links on the timing chain with the marks on the camshaft and crankshaft gears.

Step 5: Install the new timing chain

• Before installing the new chain, first of all install the guides and lubricate the gear by using a decent amount of gear oil. This will ensure that the timing chain system will perform smoothly in the future.
• Then place the new chain onto the gears while aligning it exactly with the marks previously referenced. Finish by tightening the chain according to the vehicle’s manual specifications. To do this you must have adjusted the cam sprocket.

Step 6: Replace the oil seal

• This is the rubber seal around the crankshaft. Coat the seal with oil to ensure that it is compressed. This way you will make sure that it functions correctly.
• Proceed to reinstall the cover of the timing chain.

Step 7: Reassemble all components

• Start off by bolting on the harmonic balancer, then proceed to reinstall the rest of the engine components in the reverse order of removal.
• Once reassembled, make sure that the coolant is in perfect conditions before filling the radiator in.

Always refer to the owner’s manual for specifications.

Step 8: Review that everything is working properly

• Reconnect the car battery, start the engine and check that there is no leaking or dripping, and that the warning lights are all off.

The vehicle’s timing chain determines the performance of any existing automobile. Being responsible for the engine’s correct functioning. By keeping the camshaft(s) and crankshaft in sync, they control how the engine runs, the power it delivers, the fuel it consumes and the emissions it creates.

Technological advancements have enabled the production of more durable alternatives to timing belts. The chains being increasingly silent and lighter.

These are currently gaining ground in all types of modern applications. Their purpose is no different, however, they no longer require regular maintenance and there is no need for timing chain replacement either.

As a power transmission system, chain can transmit high torque loads in a compact package. In a fraction of a second, a timing chain keeps the fuel injectors, air intake and pistons synchronized.

When a piston moves downwards, air and fuel should be going in. Then the piston goes up, a spark plug ignites the fuel, the piston is shot back down. Then, the piston rises back up to push all the remaining gas out.

Timing chain systems configurations

There are different types of timing chain systems that show unique characteristics, being the main difference in the placement of the camshaft.

The following are some of the most commonly used nowadays:

SOHC roller timing chain

While the traditional OHV (Over Head Valve) timing design, successfully used for many years, had a pushrod engine with the camshaft placed in the cylinder block, this type of engine was rather complex and would easily deteriorate at high speeds or pressure levels.

The OHV design is more suitable for larger engines; so you won’t find it in a modern compact application.

The SOHC (Single Over Head Cam) was then designed to place only one upper camshaft in the engine’s cylinder head. It means that the camshaft is usually placed in the middle of the head which denies the spark plug its ideal location where the valves are operated almost directly by the camshaft; making it easier to work at higher rpms.

The SOHC design offers several advantages over the cam-in-block design. The main one is that the number of moving parts is reduced.

DOHC roller timing chain

A DOHC (Double Over Head Cam) design involves a similarly simple configuration of an engine, with two separate cam shafts riding atop the head. This kind of engine hosts two upper camshafts that split into primary and secondary drive.

This allows the intake valves to be at a larger angle from the exhaust valves, which results in a more direct air flow through the engine and a better fuel-efficiency ratio. In most cases with a DOHC (or twin cam) engine each cam would directly operate its associated valves.

DOHC engines make possible the best of VVT benefits. This configuration shares the same advantages of the SOHC designs.

Distribution for V or W engines

Some high-end and more modern vehicles with a V or a W engine count with a complex and sophisticated design that can use up to four camshafts, involving two-cylinder heads and two rows of cylinders with their respective intake and exhaust valves.

Different timing chain types

Timing chain is considered a key element of the engine, but not all chains are the same. It exists a wide variety of types that differ in shape and design depending on different requirements as the load.

Roller and silent timing chains are the two most commonly used in vehicles. Being the first one a more complex system which link pins are reinforced by a roller support (or bushing) that accommodates freely rotating steel rollers. The major purpose of this chain type is to reduce friction.

Silent chains, also called ‘inverted tooth’ chains, are designed using metal links, which are held in place by cylindrical pins, which also allow the chain to flex.

Maintenance of Timing Chain Systems

Proper maintenance of the timing chain system is crucial for the reliable and efficient operation of your engine. Here is a summary of the maintenance process for timing chain systems:

1. Regular Inspection:

Regularly inspect the timing chain system for any signs of wear, damage, or abnormal noise. Look for loose or damaged components, excessive slack in the chain, or misalignment. Visual inspections and listening for unusual sounds during engine operation can help identify potential issues.

2. Lubrication:

Ensure proper lubrication of the timing chain system. Follow the manufacturer’s recommendations for the type and interval of lubricant to use. Adequate lubrication reduces friction, wear, and noise, prolonging the life of the chain and related components.

3. Tensioner Adjustment:

Check the tension of the timing chain regularly. If the chain shows signs of excessive slack or tensioner-related problems, adjustment or replacement may be necessary. Proper tensioning is crucial to maintain the correct timing and prevent chain skipping or failure.

4. Replace Damaged Components:

If any components of the timing chain system, such as guides or sprockets, are damaged or worn beyond acceptable limits, they should be replaced promptly. Damaged components can lead to chain instability, decreased performance, and potential engine damage.

5. Follow Manufacturer’s Recommendations:

Always refer to the manufacturer’s recommended maintenance schedule for your specific vehicle. They provide guidelines on inspection intervals, replacement timelines, and any specific requirements for your timing chain system. Adhering to these recommendations helps ensure optimal performance and longevity.

6. Professional Servicing:

For complex maintenance tasks or if you lack experience working with timing chain systems, it is advisable to seek professional servicing. Qualified technicians have the expertise and specialized tools to perform thorough inspections, adjustments, and replacements accurately.

Remember, proper maintenance is key to preserving the reliability and functionality of your timing chain system. By following these guidelines and addressing any issues promptly, you can prolong the life of your timing chain and avoid costly repairs.

Please note that the maintenance process may vary depending on the specific vehicle and engine configuration. Always consult your vehicle’s manual and seek professional advice for accurate maintenance recommendations tailored to your vehicle.

With more than 80 part numbers, GGT timing chain kits cover the most popular applications of the European car parc coverage and include all the necessary replacement components in a single package for a complete and professional replacement since the first moment.

KCSPA001, the complete solution for the 1.3 Multijet engine

The timing kit contains not only those basic components such as the timing chain, the tensioner, the sprockets, or the guide rails, this also includes the oil seal, screws, flange, and the feed pipe, being the last two essential for a truly effective replacement since the beginning.

Let’s dig in the importance of these two pieces and the main benefits this GGT Kit offers over other references.

Engine Timing Chain Kit KCSPA001: Main Benefits

Piece 1. Flange

Following the OE design, we can see that its own exploded view for the chain kit already shows this part:

The main reason why it is necessary to replace it is because it wears out and therefore it generates “game” (too much clearance) as seen in the picture below:

What does this ‘game’ affect?

1. Mainly to the correct sealing when mounting the oil seal and to prevent leaks. As observed, despite the fact that the area is “clean”, it has lost the assembly tolerances, so its performance will not be ideal.
2. Having this ‘game’ directly affects to excessive vibration generation, which can further hasten failure (reduced useful life of the kit).

Piece 2. Feed pipe

The 1.3 Multijet engine is known for “suffering” lubrication problems, that’s why the chain has been improved by General Motors, being at this moment a chain with self-lubricated holes (same timing chain as GGT includes) and even an oil feed pipe had to be designed and included for a direct lubrication of this chain as shown in the following picture:

Basically, no matter how good the maintenance of the engine and its oil changes have been, there can always be impurities and contaminants that are usually placed in the smallest holes. These dirt particles, over time, affect the condition and operation of the pieces and can even block the oil galleries and the supply holes. To obtain the best result, a new feed pipe without impurities is always advisable to guarantee perfect lubrication and help prevent future problems. For that reason, GGT also supplies this piece as part of its timing chain kit suitable for 1.3 Multijet engine (Fiat, Alfa Romero, Ford & Opel).

This part is fully accessible during timing chain assembly and besides, does not increase labor time.

After all, why use the latest OE design chain on the market if it is not going to be lubricated as it needs?

GGT: Precision for professionals

Make sure that the mating surfaces are as free from residue as possible. At Dolz/GGT we always remember that before replacing timing components, it is essential to prepare surfaces. That is the only way to make sure you will get a durable and quiet timing chain kit performance.

Now that we know some of the advantages of having these two pieces, let’s see other reasons why this GGT kit is one of the most competitive references on the market.

Learn more about the crank sprocket, the main differences between this auto part and the cam sprocket and how to choose the right components.

What does a crank sprocket do?

A crank sprocket is a part of the timing chain in engines in charge of maintaining the timing between the crankshaft and the camshaft. 

Combined with the cam sprocket, they represent two crucial gears that, when operating in synchronicity, are able to keep crank and sprocket shafts running. As a consequence, they are able to generate adequate combustion and thus make the engine run smoothly.

Camshaft vs. crankshaft: what’s the difference?

These two shafts are linked to the timing chain by the crank sprocket and the cam sprocket, so that their rotations are at the same pace.

However, they present some differences: 

• The camshaft is located at the top of the engine, the crankshaft, at the bottom.
• They perform different operations. On the one hand, the camshaft is in charge of opening and closing intake and exhaust valves. In order to do so, it employs cams, which are lobes that push against the valves as the motion of pistons propels them. On the other hand, the crankshaft uses the movement of pistons (to which it is coupled) to power the engine by rotating.
• Regarding the respective sprockets, their sizes tend to vary. Typically, the crankshaft sprocket diameter will be twice bigger than the cam sprockets. This is because of the massive load on the crankshaft due to piston’s up and down movement.

Related: The different timing chain systems

How crank sprockets work

Crank sprockets are connected to crankshafts. The sprocket rotates using the movement of pistons (to which it is coupled) and, consequently, causes the shaft to rotate as well. It is able to transform linear energy into rotational energy, and consequently allows the crankshafts to power the timing chain that will later connect to the cam sprocket and camshaft. 

What causes crank sprockets to wear down?

Like a good many products in the timing, cam and crank sprockets will inevitably wear. Sprockets may lose teeth or present signs of wear because of continued use over time. This can cause timing chains to skip and, as a consequence, result in severe engine damage. 

It’s possible to notice potential crank sprocket issues: if knocking sounds are heard when the engine is running and accelerations are performed, it could be a sign of problems. A visual inspection might confirm or discard them.

Additionally, when picking the right crank sprockets, it’s important to ensure they are durable, sprockets that don’t present sharp teeth and whose keys fit perfectly.
