MAINTENANCE
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 tap the end of the spindle with a soft
faced hammer to seat the spindle 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 1/16” 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.
