Here you will find everything related to the distribution or engine timing of your vehicle. From distribution sets to individual timing chains and conductors. The distribution takes care of the drive of the camshaft(s) and in some cases the water pump and the oil pump. It is important that the engine is 'on time', otherwise serious engine damage will occur. Modern engines are increasingly equipped with a timing chain instead of a timing belt because these engines need to be low-maintenance. However, this is not the case in practice and many engines suffer from excessive and premature wear on the timing chain. One of the reasons for this is 'downsizing', which means that many more forces are placed on the distribution.
Below you will find the right parts for your vehicle’s distribution. If you have any questions or would like advice, please contact our product specialists. They will be happy to assist you.
The timing case cover shields the timing belt or timing chain so that no dirt or moisture enters and, in the case of a timing chain, the oil remains inside the block. This is because the timing chain is lubricated by the engine oil, while the timing belt is mounted dry and shielded from the engine oil. If this cover is defective it should be replaced by a new one, to be found in this category. When assembling, remember to install a new gasket or sealing washer, if necessary, to prevent leaks. These can be found in the other product categories, "Gaskets" and “Sealing Washers".
The timing chain for your vehicle can be found in this category. If it is defective, a new one must be fitted. If it is defective or worn out, the timing is also out of order, which may result in consequential damage to the engine block. Therefore, check carefully that no consequential damage has occurred. The chain tensioners and guides should also be replaced so that the new chain is kept at the correct tension, thus improving its service life. If in doubt about the right parts or advice, please contact one of our product specialists.
The function of the timing belt is the same as that of the timing chain, to provide the drive and timing in the engine block. The timing belt has a replacement interval prescribed by the manufacturer (X kilometres / X years). To prevent any damage to the engine block, it is recommended not to exceed the interval specified by the manufacturer. Check whether the timing belt set is complete with new tensioner pulleys, otherwise these need to be ordered separately for replacement. If in doubt about the right parts or advice, please contact one of our product specialists.
You can find complete distribution sets for your vehicle here. In the case of the timing belt, this set also includes new tensioner pulleys and several gaskets. Also check the condition of the water pump when loosening the old timing belt. It may pay to replace it immediately, as the extra work is limited when combined with the replacement of the timing belt.
In the case of a distribution set for the timing chain, this set includes a timing chain, tensioner and guide rails.
The freewheel pulley forms the mechanical connection between the alternator and the crankshaft pulley. The pulley drives the alternator so that the battery is charged. The pulley protects the belt drive system by dampening engine vibrations for increased durability and comfort. The freewheel pulley can let the alternator rotor turn freely when the engine speed drops or when less energy is needed to generate power. This results in lower fuel consumption and therefore immediate lower CO2 emissions.
The reversing pulley guides the v-ribbed belt so that, among other things, the water pump, air conditioning pump and alternator are driven. Individual reversing pulleys are replaced when they have play or make abnormal noises. Usually the bearings are defective or worn out so that the roller no longer rotates smoothly.
The guides of the timing chain serve as a guide using the chain tensioner. The chain tensioner ensures the correct chain tension so that the chain will run smoothly and will not rattle. The chain guides are made of plastic and ensure that there are no peak stresses in the chain which can lead to excessive wear and tear, ultimately leading to chain breakage with all the associated consequences. In some cases, worn chain guides can be heard because the chain then makes strange noises and/or can make an abrasive noise. When replacing the chain guides, it is advisable to check or replace the (hydraulic) chain tensioner.
The drive chain for the oil pump provides the mechanical connection between the crankshaft and the oil pump for the benefit of the oil pressure in the engine block. Like other drive parts, this chain is subject to wear and tear. A defective oil pump drive chain has disastrous consequences for the engine as oil pressure is vital for the engine.
Here you will find the right chain for your vehicle for the drive of the intermediate shaft. Like the oil pump drive chain, a defective intermediate shaft drive can have disastrous consequences for the engine block, resulting in major damage.
As with the distribution chain, it is important that the drive chain of the oil pump operates at the correct tension. Correct chain tensioning ensures that there are no peak stresses in the chain which can lead to excessive wear and tear, ultimately leading to chain breakage with all the associated consequences. You can find the right tensioner for the oil pump drive chain in this category.
The v-ribbed belt drives the alternator, the power steering pump and the air conditioning pump. In some cases the v-ribbed belt also drives the water pump, but in modern cars an electric water pump is also often used. Wear and tear occurs due to age and use or, for example, due to oil leakage on the v-ribbed belt. When replacing, the guide rollers and tensioners must also be checked for correct operation. The v-ribbed belt only does its job properly when it operates at the correct tension, otherwise slippage or excessive wear may occur.
You will find the right tensioner for your vehicle's v-ribbed belt here. The tensioner ensures that the v-ribbed belt is at the correct tension and thus efficiently drives the ancillary power units on the engine block (air conditioning pump, power steering pump, alternator). If the tensioner is faulty or has too much slack, the v-ribbed belt will slip, resulting in significant loss of drive.
Repair kits for the belt tensioner arm on which the tensioner pulley runs can be found here. If it is defective, the tensioner pulley can no longer do its job of guiding the v-ribbed belt. The repair kit usually includes a new bracket/arm, fastening material and guide bushings. To be sure that you have the right parts or don’t need any extras, you can always contact one of our product specialists.
The vibration damper is attached to the crankshaft and is also the v-ribbed belt pulley that powers the multi-belt. The vibration damper serves the purpose of damping torsional vibrations of the crankshaft. The vibration damper is a 'sandwich' of two metal parts with a rubber ring in between. One metal part is attached to the crankshaft and the other part serves as a flywheel. Because of the rubber ring in the middle, a limited amount of movement is possible, which slows down the vibration and dampens it. In addition, the vibration damper serves to suppress/reduce harmonic vibrations, such as at high speeds. Harmonic vibrations can cause a great deal of damage if the vibration damper is not in order.
The right pulley for your vehicle's water pump can be found here. The water pump pulley ensures that the water pump is driven by means of a v-ribbed belt. When the water pump pulley is replaced, it is advisable to also replace the v-ribbed belt at the same time, as the v-ribbed belt must be removed for disassembly of the pulley. You will find the right v-ribbed belt for your vehicle in the category “V-ribbed belt".
The crankshaft gear is mounted on the front of the engine block, in line with the crankshaft. The crankshaft gear drives the timing chain / timing belt so that the camshafts are driven, which in turn ensures that the timing of the engine is correct. When replacing the crankshaft gear, it is advisable to also check/replace any other nearby parts, as a lot of dismantling is required for this task.
Camshaft sprockets are driven by the crankshaft gear by means of a timing chain or a timing belt. If it is damaged, it must be replaced, as otherwise serious engine damage may occur. If the camshaft sprocket breaks due to damage, the engine will break down because the timing is no longer correct. Also, a damaged camshaft sprocket can damage a timing belt, causing it to tear, also causing serious engine damage.
Complete roller sets for your vehicle can be found here, both for the timing belt and for the v-ribbed belt. When replacing the rollers, also check the operation of the tensioners and the condition of the timing belt / v-ribbed belt(s). When the rollers must be removed, it is advisable, and little extra effort, to also replace the timing belt / v-ribbed belts, which are usually also worn out when the rollers need to be replaced.
The chain tensioner ensures the correct chain tension so that the chain will run smoothly and will not rattle. The chain guides are made of plastic and ensure that there are no peak stresses in the chain which can lead to excessive wear and tear, ultimately leading to chain breakage with all the associated consequences. Worn chain tensioners can be heard in some cases because the chain then makes strange noises and/or can make a rattling noise. Also check the condition of the chain guides, as they are subject to wear and tear.
Tensioner pulleys keep the timing belt and the v-ribbed belt(s) tensioned. The tensioner pulleys are mounted on bearings and show wear in the bearings over time. Worn tensioner pulleys can jam, resulting in serious damage. When tensioner pulleys are audible (a singing sound), it is advisable to replace them immediately because they could give up the ghost in the near future. When replacing the timing belt, always also replace the tensioner pulleys and reversing pulleys.
The chain tensioner, in conjunction with the guides, ensures the correct chain tension so that the chain runs smoothly and does not rattle. The chain guides are made of plastic and ensure that there are no peak stresses in the chain which can lead to excessive wear and tear, ultimately leading to chain breakage with all the associated consequences. Compared to fixed guides, clamping tensioner guides tend to be exposed to higher loads. The reason for this is the contact pressure of the chain tensioner on the timing chain which results in a higher degree of wear and tear. In some cases, worn chain guides can be heard because the chain then makes strange noises and/or can make an abrasive noise. When replacing the chain guides, it is advisable to check or replace the (hydraulic) chain tensioner.
The tension spring in the chain tensioner ensures the correct chain tension. When this tension spring is defective or outdated, the timing chain is no longer at the correct tension, causing excessive wear and/or damage to the distribution system.
The V-belt (forerunner of the v-ribbed belt) drives the alternator, the power steering pump and the air conditioning pump, among other components. In some cases the V-belt also drives the water pump, but in modern cars an electric water pump is also often used, so the V-belt no longer drives the water pump. Wear and tear is caused by age and use, causing hairline cracks which can lead to the belt snapping. When this happens you'll end up being stranded with the car, as the drive for the above mentioned components is lost. Timely replacement prevents this inconvenience. When replacing, the guide rollers and tensioners must also be checked for correct operation. The V-belt only does its job properly when it is at the correct tension, otherwise slippage or excessive wear may occur.
Complete distribution sets with water pump and complete v-ribbed belt sets with water pump for your vehicle can be found here. Usually, the water pump is replaced as a preventive measure because it is generally at the end of its service life when the distribution set / v-ribbed belt set is also at the end of its service life. In addition, replacing the water pump is only a small job when the timing belt / v-ribbed belt has already been disassembled.
The right tensioner for the v-ribbed belt(s) and the timing belt of your vehicle can be found here. The tensioner ensures that the v-ribbed belt(s) and timing belt(s) are at the correct tension and thus efficiently drive the ancillary power units on the engine block (air conditioning pump, power steering pump, alternator). If the tensioner is faulty or limp, the v-ribbed belt / timing belt will slip, causing a significant loss of power and resulting in damage.
Complete repair kits for the intermediate shaft can be found here. This concerns, for example, an intermediate shaft between a power train of a engine block and a stub axle. The repair kits include new bearings, clips and gaskets, among other items.
