Spindles
Each blade spindle is sold as a complete unit. The
only replaceable parts are the pulley and nuts. The
spindles are equipped with a grease fittings that should
get one squirt of grease after every use of the deck
wash system or every 10 hours of use.
To replace a pulley:
1.
Remove the deck as described at the beginning
of this chapter.
2.
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 by following the procedures
described in the timing belt section of this chap-
ter.
NOTE: On 3-bladed decks, 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 8.15.
Figure 8.15
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.
