Timing chains, which have largely replaced serpentine belts on modern cars, can be replaced with complete assemblies developed by Dayco Aftermarket.

“As a company, knowing that only 16 percent of light-duty vehicles run on a serpentine belt today, we needed to evolve,” summarizes Jay Buckley, Dayco’s Director of Product Management. While at AAPEX, the supplier announced the launch of several timing chain assemblies, a 104-piece catalog that covers 95% of the demand. “We’ve focused on the most problematic models to provide simple, complete solutions for aftermarket shops.”

To support these assemblies, which include not only the chain but also the guides and tensioners that are expected to be replaced at the same time, Dayco has launched three training videos for mechanical technicians and plans to add another 20 soon, in English, French and Spanish.

“These are not parts that break often, however, when it does happen, we’re talking about a complex task that can take more than twenty hours,” says Jerry Reeves, also from Dayco. “For the independent shop, it’s an interesting job that we want to simplify with the right parts and technical guidance.”

Realizing the significant number of hours required to replace a timing chain and its accessories, Dayco guarantees its kits for two years, including parts and labor, which gives the customer peace of mind.
