Cutting Decks And Lift Shaft

Spindles
The spindles are a complete unit. The only replaceable
part is the pulley. The spindles are equipped with a
grease fitting that should get one squirt of grease after
every use of the deck wash system or every 10 hours
of use.
NOTE: Never put more than one squirt of grease
in a spindle. Putting more than one squirt in will
push the bearing out of the spindle housing,
ruining the spindle.
To replace a pulley:
1. Remove the deck as described at the beginning
of this chapter.
2. If the deck is equipped with three blades, the
center spindle pulley can be removed at this
point using an impact wrench with a 15/16”
socket to remove the pulley nut. See Figure
8.10.
NOTE: The spindle bearings are sealed. The
grease injected into the spindle housing will
break down and seep through the seals to lubri-
cate the bearings. It will also keep condensating
moisture within the spindle from reaching the
bearings.
3. Slip the PTO belt off of the spindle pulley that is
to be serviced.
NOTE: Timed decks will need to have the timing
belt removed also.
4. To access the outer spindles, remove the belt
covers. See Figure 8.11.
NOTE: Some belt covers have belt guides built
into them. See Figure 8.12.
5. Remove the pulley nut using an impact wrench
with a 15/16” socket.
6. Install the spindle pulleys by following the above
steps in reverse order.
7. Test run the tractor before returning to service.
