About this kind of part (general, written by SearchForPart)

Rides on the camshaft and passes its movement to a push rod or rocker. Wear on the roller or face causes noise and lost lift. Check the engine model and position.

When ordering, give the part number exactly as printed and its maker, and the make, model and year of the truck, trailer, reefer unit or machine (or the engine or unit serial number). SearchForPart shows fitment only as the source printed it: check it before you order.
