SERVICE INFORMATION
GENERAL
• The crankcase must be separated to service the following:

• The following parts must be removed before separating the crankcase:
- Oil filter cartridge (page 4-13)
- Water pump (page 7-16)
- Cylinder head (page 9-14)
- Cylinder (page 10-4), piston (page 10-5)
- Clutch (page 11-7). gearshift linkage (page 11-14) and primary drive gear (page 11-12)

• Be careful not t6 damage the crankcase mating surfaces when servicing.
• Mark and store the connecting rods, bearing caps and bearing inserts to be sure of their correct locations for reassem­
bly. .
• The crankpin and main journal bearing inserts are select fit and are identified by color codes. Select replacement bear ­
ings from the code tables. After selecting new bearings, recheck the oil clearance. Incorrect oil clearance can cause
major engine damage.
• Prior to assembling the crankcase halves, apply sealant to their mating surfaces. Wipe off excess sealant thoroughly.
• Whenever you replace the output driven/drive gears, bearings, bearing holder or gear case, perform the gear contact
pattern and backlash inspection and adjust the shim. The extension lines from the gear engagement surfaces should
intersect at one point.
• When using the lock nut wrench for the output gear case, use a deflecting beam type torque wrench 20 inches long. The
lock nut wrench increases the torque wrench's leverage, so the torque wrench reading will be less than the torque actu ­
ally applied to the lock nut. The specification given is the actual torque applied to the lock nut, not the reading on the
torque wrench. Do not over tighten the lock nuts. The specification later in the text gives both actual and indicated.
• Protect the output gear case with
a
shop towel or soft jaws while holding it in vise. Do not clamp it too tightly as it could
damage the gear case.
