Prevent costly failure with this IWIS Engine Oil Pump Chain Kit! This kit contains all of the basic items needed to service your oil pump drive system and prevent failure long before it occurs. Chains can stretch and chain guides and tensioners can wear out, leading to the chain skipping teeth. This prevents the oil pump from being driven at the proper speeds. If not addressed, the chain could begin to "slip" over the gears, failing to drive the oil pump. When this occurs, oil pressure will drop suddenly, failing to properly lubricate sensitive internal engine components such as main bearings, rod bearings, and camshaft ledges and lobes, resulting in severe scoring and eventual engine failure.
