Step 8:
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 the pinion does not, rotate
the pinion to seat it flush with the
bearing.
Step 9:
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
retaining screws.
•
Thread the cover retaining screws
in, leaving a slight tension to
allow for blade adjustment.
