Spindle Assembly
1
0. Apply a thin coat of lubricant to bottom seal (2)
and install with spring up toward center of
housing.
11 .
Place bottom seal squarely on housing. Select
a piece of pipe or tubing with an OD that will set
on outside edge of seal. A
tube that is too small
will bow seal cage.
12.
Carefully press seal into housing, preventing
distortion to metal seal cage. Seal should seat
firmly and squarely against machined shoulder
in housing.
13.
Make sure seal lip did not roll under. Distortion
to seal cage or damage to seal lip will cause
seal to leak. Damaged seals must be replaced.
14.
Apply a thin coat of lubricant to top seal (2) and
install with spring up away from center of
housing. Top seal should be flush with top of
housing.

. Lubricate spindle with a lithium grease of #2
consistency with a MOLY (molybdenum disul-
fide) additive. Vent top seal with a blunt edged
tool such as a letter opener while filling with
grease. Rotate housing
on spindle shaft,
checking for free movement.
Blade Spindle Installation
1. Insert spindle through bottom of mower deck
and install three mounting bolts. Be sure to
position grease fittings toward lubrication
access areas. Refer to lubrication chart.
Pulley installation sequence is
very important for bearing life. Follow the
sequence exactly.
2. Install pulley and split taper bushing with inte-
gral key on spindle shaft. Install bolt and flat
washer in top of spindle shaft. Torque this bolt
to 1.7 kg/cm (12
ft/lbs), then alternately tighten
split taper bushing bolts to 1.7 kg/cm (12
ft/lbs).
