2. Install outer bearing spacer into top of spindle housing.<br />
The spacer should fit against the snap ring.<br />
3. Using an arbor press, push the bearing cups into the<br />
top and bottom of the spindle housing. The top bearing<br />
cup must contact the outer bearing spacer previously<br />
installed, and the bottom bearing cup must contact the<br />
snap ring. Make sure that the assembly is correct by<br />
supporting the first bearing cup and pressing the second<br />
cup against it (Fig 18).<br />
4. Pack the bearing cones with grease. Apply a film of<br />
grease on lips of oil seals and O--ring.<br />
5. Install lower bearing cone and oil seal into bottom of<br />
spindle housing. Note: The bottom seal must have the<br />
lip facing out (down) (Fig. 19). This seal installation allows<br />
grease to purge from the spindle during the lubrication<br />
process.<br />

IMPORTANT: If bearings are being replaced, make<br />
sure to use the spacer ring that is included with new<br />
bearing set (Fig. 17).<br />

6. Slide spacer ring and inner bearing spacer into<br />
spindle housing, then install upper bearing cone and oil<br />
seal into top of housing. Note: The upper seal must have<br />
the lip facing in (down) (Fig. 19). Also, upper seal should<br />
be flush or up to 0.060” (1.5 mm) recessed into housing.<br />
7. Inspect the spindle shaft and shaft spacer to make<br />
sure there are no burrs or nicks that could possibly damage<br />
the oil seals. Lubricate the shaft and spacer with<br />
grease.<br />
8. Install spindle shaft spacer onto shaft. Place thin<br />
sleeve or tape on spindle shaft splines to prevent seal<br />
damage during shaft installation.<br />
9. Carefully slide spindle shaft with spacer up through<br />
spindle housing. The bottom oil seal and spindle spacer<br />
fit together when the spindle is fully installed.<br />

10.Install O--ring to top of spindle shaft. For drive<br />
spindle, position hydraulic motor mount to top of spindle.<br />
11.Install pulley (hub down), hardened washer and lock<br />
nut to spindle shaft. Tighten lock nut from 130 to 150 ft -<br />
lb (176 to 203 N -m).<br />
IMPORTANT: Pneumatic grease guns can produce<br />
air pockets when filling large cavities and therefore,<br />
are not recommended to be used for proper greasing<br />
of spindle housings.<br />
12.Attach a hand pump grease gun to grease fitting on<br />
housing and fill housing cavity with grease until grease<br />
starts to come out of lower seal.<br />
13.Rotate spindle shaft to make sure that it turns freely.<br />
