SERVICE INFORMATION
GENERAL
• All bearing inserts are select fit and are identified by color code. Select replacement bearings from the code tables. After
installing new bearings, recheck them with plastigauge to verify clearance.
• Apply molybdenum disulfide grease to the main journals and crankpins during assembly.
• Before removing the piston and connecting rod assemblies, clean the top of the cylinder off any carbon deposists.
• For servicing the piston, connecting rod, and crankshaft, the crankcase assembly must be separated (Section 1 1 ).
