2. Pick up all the components together and place
them on the steel differential lock housing.
3. Rotate all four of the thrust miter blocks until they
are flush with the top surface of the steel
differential lock housing.
4. Place the large spur gear over the differential
gear assembly.
5. Rotate the large spur gear until the screw holes
line up directly above the screw holes in the steel
differential lock housing.
NOTE: At this point, the differential assembly
should be complete and ready to be bolted
together.
6. Apply thread locker to all four of the hex head cap
screws that secure the differential assembly
together.
7. Tighten all four hex head cap screws that secure
the two differential halves to one another.
NOTE: Torque the hex head cap screws to 220-
280 in-lbs.
8. Turn the gear case input side up.
9. Remove the oil seal from the differential lock
actuator hole.
10. Turn the gear case input side down.
11. Tap the input pinion gear assembly back into the
housing.
12. Turn the gear case input side up.
13. Clean and grease the new "O" ring and the "O"
ring passage on the differential housing.
14. Clean and place the spring washer into the inlet
cavity.

15. Place the hydrostatic transmission assembly on
the differential case.
16. Place the hydrostatic torque bracket on the
hydrostatic transmission.
17. Place both of the hydro spacers between the
torque bracket and the hydro.
18. Install the 5.5" hex cap screws that secure the
torque bracket to the differential case.
NOTE: Torque the screws to 180-200 in-lbs.
19. Put the extension spring back on to the torque
bracket.
20. Remove and replace the "O" ring on each end of
the pickup tube.
21. Secure the hydro pickup tube to the transmission
using both tube clamps.
NOTE: The upper hex cap screw is secured with
a 7/16 wrench. The lower hex cap screw is
secured with a 3/8 wrench. Torque both screws
from 90-110 in-lbs.
22. Turn the gear case input side down.
23. Assemble the output shaft assembly in the
correct sequence.
NOTE: The sequence is as follows: Bearing block
assembly, two thrust washers, output shaft, 54T
bevel gear, thrust washer, needle thrust bearing,
thrust washer, shim/s (no set amount of shims),
and needle bearing block assembly.
IMPORTANT: The total depth of the needle bear-
ing block, shim/s, inner thrust washer, thrust nee-
dle bearing, and outer thrust washer, must mea-
sure between 1.153-1.158. This arrangement
must be measured out of the differential. If the tol-
erance is not met, add or remove shim/s until the
correct tolerance is achieved. See figure 2.
