Crankshaft / Cam Chain / Sprocket
Inspection
1.
Inspect the crankshaft main bearings and cam chain
sprocket for wear or damage.
NOTE: Due to extremely close tolerances and
minimal wear, the bearings must be inspected
visually, and by feel. Look for signs of discoloration,
scoring or galling. Turn the outer race of each
bearing. The bearings should turn smoothly and
quietly. The inner race of each bearing should fit
tightly in the crankshaft. The outer race should be
firm with minimal side to side movement and no
detectable up and down movement.
2.
Replace the crankshaft if the components fail visual
inspection.
3.
The connecting rod utilizes a roller bearing. Clearance is
minimal and cannot be measured. Visually inspect bearing
journal for scoring, damage or excessive wear. Replace
crankshaft if it fails visual inspection.
4.
Check oil passages to make sure they are clear.
5.
Remove cam chain. Inspect chain for wear or damage.
Replace if worn excessively or as part of any crankshaft
repair.
Crankcase / Bearing Inspection
NOTE: Removal and installation of new seals is
recommended anytime the crankcase is
disassembled.
1.
Inspect the bearings in the crankcase.
NOTE: Due to extremely close tolerances and
minimal side wear, the bearing must be inspected
visually and by feel. Look for signs of discoloration,
scoring or galling. Turn the inner race of bearing.
The bearing should turn smoothly and quietly. The
outer race should fit tightly in the crankcase. The
inner race should be firm with minimal side to side
movement and no detectable up and down
movement.
2.
To remove crankcase bearings, use a blind hole bearing
puller.
NOTE: Bearings are damaged during the removal
procedure and should not be re-used.
3.
Remove all traces of gasket material from the crankcase
mating surfaces. Inspect the surfaces closely for nicks,
burrs or damage.
Crankcase Oil Strainer Inspection
1.
Remove drain plug.
2.
Remove oil strainer and visually inspect for any damage or
obstructions in screen.
3.
Replace oil strainer if it fails visual inspection.
Note:
Install new chain as
a part of crankshaft repair.
