5.11 MOWER SPINDLES (Field Serviceable Spindles)

BEARING REPLACEMENT

In the event that a spindle bearing requires
replacement, the SNAPPER Field Serviceable
Spindles have been designed so that no special
tools or presses are required.

Remove belt. Loosen blade nut and remove.

Allow blade bolt, washer, blade and four spacers
to drop down out of the spindle housing. See
Figure 5.19.

FIGURE 5.19

Remove spindle pulley from spindle shaft.

Locate circular retaining ring on spindle shaft at

top bearing. Remove retaining ring. Allow spindle
shaft to drop out of housing.

Top and bottom bearings are now removable.

Pull out on inner race to slide bearing from
housing. See Figure 5.20.

Thoroughly clean all parts removing all old

contaminated grease.

Install new bottom bearing first.

NOTE: The bearing is sealed/shielded on one

side only. The bottom bearing must be installed
with the sealed/shielded side DOWN.

Insert spindle shaft up through the bottom

bearing. Slide spacer down over spindle shaft.

Install new top bearing. Install the top bearing

with the seal/shield UP.

10.

Slide circular retaining ring down spindle shaft

until it fully locks into groove on shaft.

11.

Apply a generous amount of general-purpose

grease to the concave side of the nylos seal.
Install the nylos seal with concave greased side
down.

12.

Place spindle pulley and spacer on top of

spindle shaft.

13.

Reinstall blade bolt, washer, blade and four

spacers. See Figure 5.15

14.

Torque blade bolt and nut to 70 to 80 ft. lbs.

15.

Pump grease into spindle housing until grease

purges from vent on housing.

16.

After the first 5 hours of operation, grease

spindle housing to insure it is full, then every 25
hours.

IMPORTANT: Spindle housing must be filled with
grease before operating mower. Failure to fill
housing

will cause premature bearing failure.
