6. Slide spacer ring and inner bearing spacer into spindle housing, then install
upper bearing cone and greased oil seal into top of housing. NOTE: The
upper seal must have the lip facing out (up)
7. Inspect the spindle shaft and shaft spacer to make sure there are no burrs
or nicks that could possibly damage the oil seals. Lubricate the shaft and
spacer with grease.
8. Install spindle shaft spacer onto shaft. Place thin sleeve or tape on spindle
shaft splines to prevent seal damage during shaft installation.
9. Carefully slide spindle shaft with spacer up through spindle housing. The
bottom oil seal and spindle spacer should fit together when the spindle
is fully installed.
10. Thread spindle nut onto shaft and tighten nut from 178 to 215 N·m (131
to 159 ft-lb).
Pneumatic grease guns can produce high pressure inside spindle
housing that can damage spindle seals. Pneumatic grease guns,
therefore, are not recommended to be used for greasing of spindle
housings.
11. Attach a hand pump grease gun to one of the grease fittings on housing and
fill housing cavity with grease until grease starts to come out of lower seal.
12. Rotate spindle shaft to make sure that it turns freely.
13. Install blade spindle assembly to cutting deck (see
(page 9–4)).
