- Inspect the oil pan rail for nicks. Inspect the front cover attaching area for nicks. Use a flat mill file to remove any nicks.
- Clean the sealing material from the gasket mating surfaces on the lower crankcase engine block side (1).
- Clean the sealing material from the gasket mating surfaces on the lower crankcase oil pan side (1).
- Inspect the crankshaft main bearing bores. Use a suitable tool (1) to measure the bearing bore concentricity and alignment. Refer to Engine Mechanical Specifications .
- Replace the engine block and bed plate if the crankshaft bearing bores are out of specification.
- Inspect the cylinder bores using a suitable tool (1). Inspect for the following items:
- Wear
- Taper
- Runout
- Ridging
Refer to Engine Mechanical Specifications for specifications.
