Before removing piston/connecting rod assemblies, ridges on cylinder walls must be removed and the engine positioned with the
Crankshaft up. The connecting rod endplay should be checked and rods and caps marked. The cap bolts are partially loosened before removal to prevent damage. The piston/connecting rod assemblies are then removed and sent for inspection and overhaul. Installation involves verifying ring end gaps, lubricating piston and rings, and using a piston ring compressor for placement. Connecting rod bearing oil clearance is checked before final installation. Cleanliness, part identification, lubrication, and attention to detail are crucial.
