Aligning the Transmission Driveshaft
Hydraulic System: Service and Repairs
The engine crankshaft and the transmission input shaft must be aligned within 3
mm (0.125 inch) of each other.
1. Verify that the driveshaft is straight and that the flanges are perpendicular to
the tube and are not bent.
2. Attach the driveshaft directly to the engine hub to allow verification of
driveshaft alignment.
3. Loosen square-head screws (item 7 in
transmission input shaft. Slide pump hub toward engine, align holes in pump
hub with driveshaft flanges, and place bolts in holes.
4. Rotate driveshaft to check alignment of the driveshaft in all positions.
Driveshaft and hub must be aligned within 3 mm (0.125 inch).

Note: If necessary, loosen the lift arm carrier bracket before installing shims
between frame and axle mounting pad.
6. Loosen fasteners that secure front axle to frame. Install shims between frame
and axle mounting pads to adjust location of transmission input shaft.
A. If the transmission input shaft is high at the drive coupling, lower input
shaft by installing shim(s) between the rearward axle mounting pads and
the frame (or by removing shim(s) that may exist at forward mounting
pads).
B. If the transmission input shaft is low at the drive coupling, raise input shaft
by installing shim(s) between the forward axle mounting pads and the
frame (or by removing shim(s) that exist at rearward axle mounting pad).
