CRANKSHAFT / CAM & OIL CHAIN /
SPROCKET INSPECTION
1. Inspect the crankshaft main bearings and cam and oil pump
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.
