1. While supporting bearing's inner race, drive the shaft
into the bearing until it seats on the shoulder of the
shaft.
2. Install the arbor assembly into the lower housing.
Pack the housing with multipurpose grease.
NOTE: Clean all excess grease off the mating flange
area.
NOTE: Be sure to replace the foam gasket. If a replace-
ment gasket is not used, seal the lower and upper hous-
ings with RTV or silicon sealer.
3. Install the upper housing onto the lower housing
assembly, align the pins, and clamp together. Check
the shaft for smooth, easy rotation of bearings.
NOTE: New bearings will feel stiff but will still rotate
smoothly.

blade adapter on the blade end of the arbor shaft.
Secure with the collar.
NOTE: The blade end of the arbor shaft has recessed
spines to hold the collar.
5. Assemble the upper grass shield and pulley on top of
the arbor shaft. Secure with the heavy washer, lock
washer and capscrew. Torque to 50-70 ft. lbs.

Arbor Assembly Removal steps 6-7) Secure with six
Taptite hex screws.
