Adjustments
DRIVE CHAIN TENSION - DIRECT DRIVE CHAIN
Drive chains between hydro pump output shafts and axles
should be inspected frequently during the first hours of
operation. After initial chain wear-in, chains should not
stretch. To adjust chains:
1. Rotate the wheel and check sprocket for high point
when chain is the tightest. Perform adjustment with
chain in this position to avoid overtightening.

2. Loosen the four 7/16" bolts (A, figure 27) holding the
axle plate assembly to the frame.
3. Tighten the draw nut (B) on the bottom until slack is
removed. Do not overtighten.
4. Retighten four bolts (A) and torque to 50 ft. Ibs.
DRIVE CHAIN TENSION - DOUBLE-CHAIN REDUCTION
Primary (Bottom) Chain
Drive chains between hydro pump output shafts and axles
should be inspected frequently during the first hours of
operation. After initial chain wear-in, chains should not
stretch.
Primary chain adjustment will affect position and tension of
secondary (top) chain and should be adjusted first. To
adjust, follow these steps:
1. Rotate wheel and check sprocket for high point when
chain is tightest. Perform adjustment with chain in this
position to avoid overtightening.
2. Loosen two nuts (A, figure 28) securing jackshaft plate
to axle plate.
