There are up to three shim washers before the
first bevel gear on the drive shaft. They will
vary in thickness, are factory installed and
should not be changed. Electronic shimming
has determined the tolerance needed. The
backlash is factory set on this transaxle to
between 6 to 10 thousandths. The factory uses
a 40 thousandths washer on each side of the
drive shaft and then adds a 10 thousandths
washer as needed to arrive at the proper back-
lash. The 40 thousandths washer is part num-
ber 736-0444. The ten thousandths washer is
part number 736-0454.
