When to Overhaul an Engine
The countershaft bearing shell is sold individually as a half-shell. During an engine overhaul, replacing the bearings is essential to restore proper engine function and prevent future damage caused by excessive wear, which could lead to the replacement of other mechanical components. The engine bearing is a crucial component that ensures the proper functioning of moving engine parts, reducing friction between the crankshaft and other mechanical elements. Over time, bearings can wear out due to high temperatures and continuous load, compromising engine efficiency and potentially causing severe damage. Timely replacement of a worn bearing can prevent major engine damage, extend its lifespan, and ensure smooth operation.
Signs of Engine Bearing Wear:
Metallic noises or irregular knocking
Reduced oil pressure
Unusual vibrations or performance drops
Select the quantity based on the type of engine being overhauled. To overhaul a 660 engine, you need to purchase 6 half-shells. Check the tolerances and bearing colors according to the workshop manual.
