5. Tap the square key into place in the upper
shaft. Wrap masking or electrical tape around the
shaft and key. This will keep the key in place and
will prevent the shaft from slipping out of the
housing during reassembly to the mower deck.
6. Reinstall the lube filling in the top of the shaft.
SPINDLE REINSTALLATION
1. Place the spindle into the deck from the
bottom and retain with 7/16 fine thread locknuts.
Torque all four nuts to 35-45 ft. lbs. (48-61 Nm).
2. Remove the tape from the spindle shaft and,
while holding the shaft from the bottom, install
the belt pulley, 3/4 flat washer and 3/4-16
locknut.
3. Install the spindle washer, mowing blade,
blade spacer and 9116-12 x 1-3/4 Grade 8 bolt.
See parts page 28 for item illustrations.
4. Torque the blade bolt, using a spanner wrench
through the holes in the pulley, to 110-130 ft. lbs.
(150-1 77 N Torque the pulley nut to 80 ft. lbs.
(109 N-m). Re-torque these fasteners after one
hour of mower operation and daily thereafter.
5. Lubricate the spindle with a high quality
multipurpose grease until the grease begins to
vent from around the UPPER seal.
IMPORTANT.
The rebuilt spindle should be greased again after
15 minutes of operation to ensure that air
pockets in the spindle housing have been fully
purged
