Installation Notes
Crankshaft installation is the heart of any engine rebuild, so check all journal dimensions and use Plastigage to verify clearances. Cleanliness during assembly is paramount—any dirt or debris will destroy your new bearings. Take your time with torque specifications and assembly procedures. It’s precision work, but the reward is an engine that runs like new and keeps you in the field instead of the repair shop.
