What does the '.030' in the product name mean?

The '.030' indicates that these main bearings are 0.030 inches smaller than the standard size. This means they are intended for use with a crankshaft that has been machined down by 0.030 inches to correct wear and restore proper clearances.

What vehicles does this main bearing set fit?

This set fits a broad range of Willys and Jeep models from 1941 to 1971, including the MB, CJ2A, CJ3A, CJ3B, CJ5, CJ6, Jeepster, FC-150, FC-170, M38, and M38A1, provided they have the 134 ci L or F-Head engine.

Does this set include everything needed for installation?

This is a complete set of main bearings for your engine. However, installation of internal engine components like main bearings requires specialized tools and knowledge, and often involves other parts such as gaskets and seals, which are sold separately.

Product Details

When you're rebuilding a worn-out engine, replacing the main bearings is a critical step to getting back that original power. This Omix main bearing set is specifically sized at 0.030 inches undersize, meaning it's meant for a crankshaft that has already been machined down to that size. This is a common practice when dealing with worn crankshaft journals to restore the engine's proper clearances.

Omix offers these replacement engine components to help get your classic Willys or Jeep back on the road. This set includes all the main bearings needed for your 134 cubic inch L-head or F-head engine. It's designed to fit a wide range of models from 1941 through 1971, including popular vehicles like the CJ5, CJ6, and various Jeepster and FC models. Proper installation will require engine work, as these are internal engine components.
