To Change Spindle Bearings (Fixed Decks Only) - Cub Cadet Commercial 1536H Operator's And Service Manual

6. TO CHANGE SPINDLE BEARINGS (Fixed Decks Only):

(See the exploded view drawing on page 19.)
a. Clamp the spindle assembly in a vise with the grease fitting pointing up.
b. Bend down the tab of the tab lockwasher.
c. Remove the hex jam nut.
d. Obtain a round wooden dowel about 6-inches long such as a piece of broom handle. Hold this
wooden dowel on top of the spindle and tap it with a hammer to drive the spindle out of the
bearings and the spindle housing.
e. Pull the seal spacer out of the top seal.
f. Using a large screwdriver, pry the seals out of each end of the spindle housing. (NOTE: You will
destroy the old seals as you remove them.) As you remove the old seals, the inner races of the
roller bearings and the internal spacer will fall out of the spindle housing.
g. Using a bearing puller, remove the outer races from both ends of the bearing housing.
NOTE: If the outer races cannot be removed using this procedure, take the spindle housing to a local machine
shop and let them remove the bearing races.
h. Clean the old grease out of the spindle housing.
i. Clamp the housing in a vise with the grease fitting pointing down.
j. Gently drive a new bearing outer race back into the spindle housing using the wooden dowel. Make
certain that the tapered side of the race faces outward.
k. Pack one inner race with fresh grease and place it into the outer race.
l. Press one of the new seals into the spindle housing by using the wooden dowel, moving around the
circumference of the seal and tapping gently with a hammer.
NOTE: The metal surface of the seal should face outward.
m. Turn the housing over and re-clamp it in the vise with the grease fitting pointing up.
n. Gently drive the second bearing outer race back into the spindle housing using the wooden dowel.
Make certain that the tapered side of the race faces outward.
o. Insert the internal spacer.
p. Pack the second inner race with fresh grease and place it into the outer race.
q. Press the second new seal into the spindle housing by using the wooden dowel, moving around the
circumference of the seal and tapping gently with a hammer. NOTE: The metal surface of the seal
should face outward.
r. Coat the spindle with grease and push it up through the bottom of the spindle housing. The spindle
will pass through the lower seal, an inner race, the internal spacer, an inner race and the upper
seal.
s. Hold the spindle in place and install the seal spacer down over the spindle and push it into the top
seal. There is a notch on one of the inside edges of the seal spacer that should be facing up and
should be opposite the side of the spindle with the keyway. Install the new tab lockwasher with its
bent inner tab pointing down to engage with the notch in the seal spacer. Install the hex jam nut and
torque it to 100 ft. lbs. Bend up the large tab on the tab lockwasher to hold the jam nut in place.
