Adjust drive axle parallelism.
•
Distance between the drive axle hub centers on the left and right side of the
machine should be within 1/8 in. (3.2 mm). This can be measured, or the
process can be simplified by use of a Trammel bar if available.
•
If adjustment is required, make the adjustment to the rear drive axle mounting
shims. Reposition the shim/s to the front of the bar pin to move the axle forward,
or to the back of the bar pin to move the axle toward the rear. Slight adjustments
might be achieved by adjusting shims on one side of the axle. Larger adjustments
will be achieved by adjusting both sides in opposite directions. Re-torque
hardware to 450-600 lbf*lb. (610-813 N*m).
Note: Raise the machine on outriggers to take weight off the suspension in order to reposition
the mounting shims. A Porta Power can be used to support the suspension. Be sure to lift the
outriggers and put full weight on the suspension prior to taking subsequent measurements.
