Pump Belt Removal:
1. Remove deck belt (see Deck Belt Removal)
2. Rotate idler arm to relieve belt tension. The
idler arm has a 1/2” square hole to accept a 1/2”
breaker bar to gain leverage over the spring.
3. Remove belt from engine and hydro sheaves.
Note: Belt routed above park brake cross shaft. It
must pass between the shaft and clutch housing.
This necessitates the disconnection of the clutch
jumper harness from the clutch. It may also be
necessary to loosen or remove the clutch anchor to
allow the clutch to rotate thereby creating more
clearance to the cross shaft.
