Assembly
IMPORTANT: When greasing spindles, grease
passes into the center of the shaft and out to fill the
bearing cavity of the housing. If grease does not
come out of lower seal when greasing, check lu-
brication hole in spindle shaft for obstruction.
IMPORTANT: If new bearings will be installed into a
used spindle housing that has the original large
snap ring installed, discard the snap ring that came
with the new bearings because it is not necessary
to replace the original snap ring. However, new
bearings with their matched spacer set and snap
ring must always be installed when the spindle
housing is being replaced. Replacement bearings
are sold only with a matched snap ring and spacer
set. These parts cannot be purchased separately.
10.Install spindle plug to top of spindle housing. Attach
a hand pump grease gun to either grease fitting and fill
housing cavity with grease until grease starts to come
out of lower seal. NOTE: Pneumatic grease guns can
produce air pockets when filling large cavities.
