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 press the spindle to seat the cone onto the
spindle.
5 – 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.
6 – 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.
7 – 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 (thick nut) and hand tighten against jam washer and adjustment nut.
See the following section for bearing adjustment.
8 – Position the spindle housing horizontally with the drain hole oriented “up.” Grease
through the zerk with Tiger Spindle Lubricant(part number 06540000) until the grease
purges from the drain hole.
9 – Install the plug into the drain hole.
