LOSS OF POWER IN THE DRIVE
SYSTEM
Check the fl uid level and make sure the prop-
er amount of fl uid is in the reservoir. Make
sure all hydraulic connections are tight and
not leaking. Make sure drive belt is tight and
not slipping. Check park brake adjustment.
Make sure pump bypass valve is tight so
pump does not freewheel.
DRIVE BELT REPLACEMENT

1. Remove the deck belt (A) as described in
“Deck Belt Replacement” section (page
36).
2. Remove the clutch center bolt (B) and
slide the clutch (C) off the engine's crank-
shaft.
3. Loosen the .375" idler arm pivot bolt (D)
and remove the .312" bolt (E) securing
belt tensioner bracket in place. Using a
half inch drive break-over bar or racket,
inserted in half inch square hole, rotate
idler pulley away from belt, relieving belt
tension.
4. Remove the belt (F) from pulleys.

bracket loose. Using the break-over bar,
reinstall the .312" bolt (E) (normally in
center hole) in the idler tensioner bracket
and secure. Do not over tighten belt, Belt

from slipping. Retighten .375 idler arm
pivot bolt (D).

Belt Replacement” section (page 36).
