When to Rebuild an Engine

The countershaft bearing half-shell is sold individually per half-shell. During the rebuilding of an engine, replacing the bearings is essential to restore the proper functioning of the engine, avoiding future damage due to excessive wear that could lead to the replacement of other mechanical parts. The engine bearing is a very important component that ensures the proper operation of the engine’s moving parts by reducing friction between the crankshaft and other mechanical parts. Over time, bearings can wear out due to high temperatures and continuous load, compromising the engine’s efficiency and causing potential damage. Timely replacement of a worn bearing can prevent serious engine damage, prolong its life, and ensure smooth operation.

Signs of Engine Bearing Wear:

• Metallic noises or irregular knocking sounds
• Reduced oil pressure
• Unusual vibrations or performance drops

Select the quantity based on the type of engine to be rebuilt. To rebuild a 660 engine, you need to purchase 6 half-shells. Check the tolerances and colors of the bearings through the workshop manual.
