PTO SIDE CRANKCASE BEARING SERVICE
Bearing Removal
NOTICE
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 inner 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 minimal side to side movement
and no detectable up and down movement.
Bearings are stressed during the removal process and
must not be re-used!
1. Remove and discard the PTO side crankshaft seal.
Replace with new for assembly.
2. If not already performed, remove the screws that
secure the bearing retainer to the case.
3. Remove the retaining ring.
4. Support the crankcase and drive, press, or extract
the three bearings with a blind bearing remover.
