NOTE: The decks used on RZT-S mowers have fixed idlers and movable idlers.
Fixed idler pulley
To remove/replace a fixed idler pulley:
1. Remove the deck as described at the beginning of
this chapter.
NOTE: Removal of the deck is not necessary, but makes it
easier to route the belt around the spindles.
2. Remove the nut and bolt that hold the idler pulley to
the deck.
NOTE: As the pulley is loosened, the belt guide will open
enough so that the belt can be slipped off of the
pulley.
To install the pulley:
3. Trap the belt between the pulley and the belt guide.
4. Insert the bolt through the pulley and the belt guide to
help hold them together.
5. Bolt the pulley to the deck, ensuring that the detent
on the belt guide seats in the hole in the deck. See
Figure 7.10.
6. Re-install the deck, if removed.
7. Test run the mower before returning to service.
Moveable idler pulleys and brackets
To remove/replace a moveable idler pulley:
1. Remove the deck as describe at the beginning of this
chapter.
NOTE: Removal of the deck is not necessary, but makes it
easier to route the belt around the spindles.
2. Remove the nut, bolt and bearing cup that hold the
idler pulley to the idler bracket. See Figure 7.11.
NOTE: As the pulley is loosened, the belt guide will open
enough so that the belt can be slipped off of the
pulley.
