101291 - Main Bearing Set .010" Under Size - B18 B20 B21 B23

Product Description

Rod and main bearings are replaceable wear items inside your motor. The clearances involved are very small and precise and it’s best to have them inspected by a machine shop whenever disassembled. They should always be replaced when rebuilding, which may require machining and a new size of bearing. Rod knock is due to excess clearance in the rod bearings and machine work is usually required for a proper repair.
