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

Keeps oil, coolant, fuel or air inside the engine where a shaft turns or two parts meet. Leaks at the crankshaft ends or around shafts are the usual sign. Check shaft size and position (front or rear).

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.
