SERVICE INFORMATION
GENERAL
The crankcase must be separated t o service the crankshaft and transmission. Refer t o section 11 for crankcase separa-
ti on/assem bly.
Be careful not t o damage the crankshaft main journal and journal bearing while removing or installing the crankshaft.
Mark and store the disassembled parts t o ensure that they are installed in their original locations.
Mark and store the bearing inserts t o ensure that the parts are i n their correct locations during reassembly. If the inserts
are improperly installed, they will block the oil holes, causing insufficient lubrication and eventual engine seizure.
The main journal bearing inserts are a select fit and are identified by color codes. Select replacement bearings f r o m the
code tables. After installing new bearings, recheck t h e m w i t h a plastigauge t o verify clearance. Apply molybdenum disul-
fide oil t o the main journal during assembly.
