Checking Drive Coupling Alignment (Fig. 2)
When either the hydrostatic axle or the engine is re•
moved and after all parts are reinstalled, the alignment
of the drive coupling must be checked. In addition, any
excess vibration usually indicates misalignment of the
drive coupling. The drive coupling will be damaged
when misalignment is more than 1/8 inch (3 mm).
To check the alignment of the drive couplings, place the
square end of a ruler or scale against the face of the
drive pulley and the bottom of the coupling retainer).If
there is more than 1/8 inch (3 mm) between the ruler or
scale and the opposite coupling retainer, or the scale is
more than 1/8 inch (3 mm) higher than the bottom of the
coupling, an adjustment is required. To correct for a
misaligned drive coupling, proceed to “Adjusting Drive
Coupling Alignment” which follows.
Figure 2
Adjusting Drive Coupling Alignment (Fig. 3, 4)
To correct drive coupling misalignment, first loosen the
axle support nuts at the rear of the floor plate).
A transmission that is too high at the drive coupling end
may be lowered by installing a 1/16 inch (1.6 mm)
spacer between the rear of the mounting pad and the
bottom of the frame. A transmission that is too low is
corrected by installing a 1/16 inch (1.6 mm) spacer
between the front of the mounting pad and the bottom
of the frame.
To install the spacers, remove the appropriate two cap
screws and loosen the other two. If the spacers must be
added to the front of the mounting pad, remove the front
cap screws and loosen the back ones. Do just the
opposite to add spacers at the rear of the mounting
pads.
Figure 3
After adding the spacers, install the two cap screws and
tighten all of the cap screws to secure the axle in place.
Check the alignment again. Continue to check the align•
ment and add shims as required. When the alignment
is correct, tighten the axle support nuts. Tighten the rear
nut with the fingers until it contacts the frame; then
tighten the front nut securely. Secure the rear nut last.
