OE power transmission specialist Dayco is providing workshops with an important additional business opportunity with a broad range of OE damper pulleys.  

Modern compact engines often exhibit high levels of engine vibration. This vibration is transmitted through the crankshaft and therefore has a significant impact on the engine’s power transmission systems, and the front-end auxiliary drive (FEAD) in particular.

As a supplier to the world’s leading vehicle makers, Dayco has the technical knowledge and experience to engineer effective solutions for these and many other engine system problems and has developed a range of damper pulleys to help absorb this vibration.

Generally installed directly to the crankshaft, the damper reduces the circular vibrations that cause the primary problem, decreasing wear on many of the engine’s components. Naturally, the FEAD system is a principal beneficiary, which increases the durability of the entire powerplant. 

As a wearing part, over time the damper can lose its efficiency or sometimes even break, increasing the risk of failure in other parts of the engine’s drive systems. This means workshops should regularly check them for signs of wear, such as abnormal noises and unpleasant vibrations, at 40,000-mile intervals or when replacing the auxiliary belt. 

Technicians must be aware however, that to check the damper correctly, it needs to be removed from the engine because the back, as well as the front, needs to be examined to fully assess its condition, particularly the visible rubber elements. In addition, whether it needs to be replaced or not, if its fixing bolts are designed to stretch on initial fitment, these must be changed, as, if reused, they will no longer meet their VM design tolerances.

Dayco damper pulleys are produced in the same facilities, to identical standards, to OE, offering the highest quality and total peace-of-mind. For maximum convenience each Dayco damper that has a VM specified instruction to replace its bolts, comes complete with the correct specification bolts in the kit.

As a further helpful means of identification, these kits come with a K at the end of the part number, for example DPV1210K, the most popular reference for the 2.2 and 2.4-litre TDCi powered Ford Transit and Tourneo, manufactured between April 2006 and August 2014. So, this added suffix provides an additional aid to help technicians follow installation best practice.

The complete DVP programme consists of more than 160 part numbers and provides coverage for 95% of the European vehicle parc. These are available from Dayco stockist nationwide.
