NOTE
The PTO w and MAG e side main bearings are not
serviceable. Crankshaft replacement is required if the
bearings are damaged or have excessive wear.

Maximum Runout:
Mag side e - 0.002″ (0.05 mm)
PTO side r - 0.002″ (0.05 mm)

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 outer race of each
bearing should fit tightly in the crankcase. The inner
race should be firm with no side to side movement and
no detectable up and down movement.
