FIGuRE 40
A properly installed, replacement bearing should rotate
without excessive friction, drag and/or “rough spots”. If
these symptoms occur after assembly, the bearing was
improperly supported when pressed on the driveshaft
or into the housing. The resulting thrust placed upon
the bearing exceeded its static capacity. A bearing
operating with these characteristics will deliver minimal
service life and be prone to premature failure.
13) Reinstall the bearing block/bearing and driveshaft
assembly to the main frame.
14) Follow the procedures as outlined in this manual
for the proper installation of the pulleys and v-belt
assemblies.
15) Reinstall the belt guard to the main frame.
16) Reconnect the spark plug wire to the spark plug.
UNEXPECTED MACHINE START UP CAN RESULT
IN PROPERTY DAMAGE AND/OR PERSONAL
