ADJUSTMENTS
TRACTION DRIVE HYDROSTAT ADJUSTMENTS: The following adjustments must be done in order.
STEP 1 - Set Neutral
Neutral is set at the factory. If it should require
adjustment, raise the wheels off the ground by
supporting the machine on jackstands or blocks.
Disconnect the control rod
A at each pump end.
Loosen bolt S securing the neutral plate eccentric
shaft just enough to turn the shaft. Start the engine
and run at low speed. Turn eccentric shaft
T to raise
or lower the point at which the follower bearing is held
in the center of the “
V ” until the wheels stop turning.
Tighten the eccentric shaft bolt. Increase the throttle
setting and check the adjustment. Readjust if
necessary. Shut the engine off before proceeding to
Step 2.
STEP 2 - Adjust Control Rods
First adjust neutral, as outlined in Step 1. Set control
levers to neutral. Adjust swivels
B on lower ends of
control rods A so they just go into the holes on the
pump arm control plates.
After adjusting swivel B on left side, tighten jam nut C .
