5.8  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. 
1.  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 
5.10. 
 
 

2.  Remove spindle pulley from spindle shaft. 
3.  Locate circular retaining ring on spindle shaft at 
top bearing. Remove retaining ring. Allow spindle 
shaft to drop out of housing. 
4.  Top and bottom bearings are now removable. 
Pull out on inner race to slide bearing from 
housing.  See Figure 5.11. 
5.  Thoroughly clean all parts removing all old 
contaminated grease. 
6.  Install new bottom bearing first. 
7.  NOTE: The bearing is sealed/shielded on one 
side only. The bottom bearing must be installed 
with the sealed/shielded side DOWN. 
8.  Insert spindle shaft up through the bottom 
bearing. Slide spacer down over spindle shaft. 
9.  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.

IMPORTANT: Spindle housing must be filled with 
grease before operating mower. Failure to fill 
housing will cause premature bearing failure. 
 

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.
