Assembly and Installation of Spindle
IMPORTANT: If a new spindle housing is being used,
new bearings and matched snap ring set must be
installed; see step 1 below. Never use old bearings,
spacer, and snap ring with a new spindle housing.
If installing bearings into a used spindle housing
that still has a snap ring installed, use only new
bearings with cups and spacer – not the large snap
ring because it is not required; see step 2 below.
1. Install large snap ring into groove in bore of spindle
housing. Make sure snap ring is seated in groove.
2. Using an arbor press, push large spacer into top of
spindle housing; tightly against snap ring. The spacer
must contact the snap ring to be sure of the correct
assembly of the parts.
3. Thoroughly oil the bearing cups and using an arbor
press, push the bearing cups, smallest inside diameter
first, into the top and bottom of the spindle housing. The
top bearing cup must contact the spacer that was in-
stalled in step 2, and the bottom bearing cup must
contact the snap ring to be sure of the correct assembly
of parts. Insure that the assembly is correct by support-
ing the first cup and pressing the second against it.
4. Apply a film of grease on lips of both seals, then install
bearing and seal into bottom of spindle housing. Re-
member, the
BOTTOM SEAL MUST HAVE THE LIP FACING
, not toward the inside of the spindle housing.
OUTWARD
5. Check the spindle shaft to make sure it is free of burrs
and nicks that could possibly cut the seals and thor-
oughly lubricate both the shaft and seal lips.
6. Slide small, thick spacer into spindle housing, then
install bearing and seal into top of spindle housing.
OF UPPER SEAL MUST FACE INWARD
7. Slide bearing spacer onto spindle shaft. Carefully
slide spindle shaft through spindle housing. The bottom
seal and bearing spacer fit together when the spindle is
installed.
8. Push pulley onto splines of spindle shaft and retain
the parts together with the large flat washer and nut.
Tighten the nut to 100 - 120 ft-lb and rotate the spindle
shaft to be sure that the shaft rotates freely.
9. Slide pulley end of spindle assembly through hole in
cutting unit. Mount the spindle assembly in place with
the carriage bolts and flange nuts.
10. Install the belt and adjust belt tension.
11. Reinstall the belt covers.
