Quad engine bearings and bearing kits

Identify the bearing's job

The listings cover different engine locations, including crankshaft, piston and connecting-rod applications. Match the reference to the part of the engine being serviced, using the complete vehicle and engine details in the application.

For bearings with listed dimensions, compare inside diameter, outside diameter and length or width as stated. Dimensions provide another check; they do not replace the exact application or bearing specification.

Read the exceptions in a kit description

A family description may be followed by a note saying that a particular kit has only one bearing or excludes seals. Read those specific notes before deciding what the kit contains. Do not assume that every product called a main-bearing kit supplies the same number of bearings and seals.

The purchase unit may be Each, Pair, Set or Kit. Use the contents for the exact reference to work out what is supplied and whether the intended repair needs additional parts.

Choose related engine parts separately

For associated components, browse crankshafts and connecting rods, pistons and rings or gaskets and seals. Check the application and contents of each listing; an engine-bearing kit is not automatically a complete rebuild kit.
