pad (C) to the PTO clutch (D) and disconnect the wire
harness from the PTO clutch.
WARNING
STORED ENERGY DEVICE: Improper release of the belt
tension spring can result in personal injury. Use extreme
caution when removing the spring.
4. Loosen the jam nut (E) on the spring anchor eye bolt (F).
5. Loosen the adjustment nut (G) on the spring anchor
eye bolt to release the majority of the belt tension. Use

Rotate the pulley support plate away from the hydraulic
tank mount so that the belt can be removed from the
machine.

Figure 61). Make sure that the V-side of the belt runs in
the grooves of the front stationary idler pulley (I), both
transmission pulleys (J) and the crankshaft pulley (K).
Make sure that the flat side of the belt contacts the faces
of the adjustable idler pulley (L) and the stationary idler
pulley (M).

position and secure to the hydraulic tank mount plate (G)
using the two (2) 5/16" bolts (D), 5/16" flat washers (E),
and 5/16" nylock flange nuts (F).

the pulley support plate (B) to the front stationary pulley
stack-up (C).
11. Reinstall the spring anchor eyebolt (F, Figure 61) into the
spring anchor tab and loosely fasten the adjustment nut
(G).
12. Tighten the adjustment nut until the spring (N) achieves a
coil-to-coil measurement (O) of 5-3/4" (14,6 cm).

14. Reinstall the clutch anchor pad (C) to the PTO clutch (D)
and secure using the hardware (B) previously removed.
Reconnect wire harness to the PTO clutch.
