MAINTENANCE
SPINDLE SERVICE PROCEDURE (Cont’d)
1. Using a 3/16” cape chisel, bend out the staking indentations on each side of the bearing adjusting nut. To
do this, place the chisel in the groove and parallel to the shaft. Drive the chisel downward until the
indentation is free of the shaft and threads (see Figure 1).
2. Using the same chisel, straighten the tang on the lockwasher (if equipped with a lockwasher).
NOTE: The lockwasher will not be installed during assembly if the spindle uses the staked adjusting nut.
3. Remove bearing adjusting nut and lockwasher (if equipped). Discard these parts. They are not reusable.
Install a new adjusting nut when assembling.
4. Screw the original blade bar bolts into the flange of the spindle shaft until they contact the bearing ring (see
Figure 2).
5. In a clockwise pattern, rotate each bolt 1/4 turn (see Figure 3). Continue turning the bolts 1/4 turn at a time
(maximum of 3 turns), until the special shanked bolts (P/N 02964353) will thread into the spindle.
6. Remove the original bolts and replace them with the shanked bolts. Screw the shanked bolts in until they
contact the bearing ring.
7. In a clockwise pattern, rotate the bolts 1/4 turn at a time until the spindle is free from the housing.
8. Remove the seal retaining ring from the housing using a flat screwdriver or similar tool.
9. Remove the seal and bearing.
10. A punch or similar tool can be used to remove the bearing cups from the housing if the cups are not to be
re-used.
CLEANING
1. Clean housing and all related parts thoroughly and dry.
2. Protect parts from contamination.
INSPECTION
BEARINGS AND CUPS: Inspect rollers, races and cages for nicks, pitting, discoloration, and signs of exces-
sive or unusual wear. Replace any worn or damaged parts.
SPINDLE SHAFT: Inspect the threads, internal splines and bearing journals for damage or wear. Replace if
damaged or worn.
BEARING RING: Inspect the ring for wear in the area of seal contact. Replace if a wear groove exists.
HOUSING: Inspect the bearing cup bores, ring grooves, etc. for wear or damage. Repair or replace if any
damage is found.

2. Seat bearing cups (outer races) in housing using a press and proper installation tools in good
