Step 4: Install Pinion
Insert the pinion into the bearing bore.
The pinion should go in with minimal
effort and not require pressing.
Do not force the pinion into the
bearing. If the pinion does not go in
easily, check bearing and pinion for
damage or build-up.
The pinion should sit flush against the
bearing. If it does not, rotate the
pinion to seat it flush with the bearing.
Step 5: Install Cover and Blade Housing
Set the blade housing on the frame
and place the cover plate over the
blade housing.
While holding the cover plate firmly
against the housing and frame, start
the two cover mounting screws.
Thread the cover retaining screws in,
leaving a slight tension to allow for
blade adjustment.
