BEARING INSTALLATION
1. Press upper bearing cup into the spindle
housing
2. Turn the spindle housing over and press in the
lower bearing cup.
3. Place the lower bearing cone in the bearing
cup. Next press the seal into the spindle
housing. The inner lip of the seal must be
DOWN, towards the bearing, so lubricant is
sealed inside the housing.
4. Install the spindle in the housing. Lightly press
the end of the spindle to seat the sp indle
against the bearing inner race.
5. Turn the spindle housing over (up position) and fill with Tiger Spindle Lubricant (part number 06540000) to
the top edge of the upper bearing cup.
6. Support the bottom of the spindle and press the upper bearing cone and bearing adjustment sleeve onto
the spindle.
NOTE: The spindle housing must turn freely when seating the bearing cone and sleeve.
7. Press the two upper seals into the spindle housing. The inner lip of the seals must be UP, away from the
bearing, so excess lubricant can escape.
8. Install the bearing adjustment nut (thin nut) so there is 1-1/6” clearance between the nut and the sleeve.
Install the jam washer, placing the tab into the key-way. Install the bearing lock nut (thin nut) and hand
tighten against jam washer and adjustment nut. See the following section for bearing adjustment.
BEARING ADJUSTMENT
1. Clamp the bottom end of the spindle securely in
a vise so the spindle housing turns freely.
2. Position a magnetic base dial indicator on the
outer diameter of the spindle housing. Locate
the end of the dial indicator against the flat end
of the spindle shaft. The dial indicator will now
measure accurately bearing end play.
3. Tighten the bearing adjustment nut until there is
0.012 inch movement when the spindle housing
is pried upward away from the vise jaws.
4. When there is 0.012 inch free play between the
spindle and housing, install the bearing lock nut
(thick nut). Hold the adjusting nut securely and
tighten the lock nut to 300 ft. lbs. of torque.
5. After the lock nut is tightened, there must be 0.001 inch to 0.003 inch of free play when lightly prying up on
the spindle housing.
If the end play is correct, 0.001 inch to 0.003 inch, bend tabs up on jam washer to prevent the lock nut from
loosening.
If the end play is NOT correct, loosen the lock nut and turn the adjustment nut as required and re-tighten the
lock nut. Repeat first part of step 5.
