Assemble - Taylor-Dunn B0-248-TT Operation, T Roubleshooting And Replacement Parts Manual

Assemble

NOTE: Thoroughly clean and inspect all parts before
reassembly. Apply a small amount of
differential oil to all gears and bearings before
reassembly.
NOTE: Depending on your vehicle config-uration, the
rear pinion pilot bearing is not required and
may not be installed.
NOTE: If the ring and pinion gear set is to be replaced
then the shims for the pinion housing may
have to be adjusted. Refer to section
Selecting the Pinion Housing Shim
information on adjusting the shim.
NOTE: Most of our gear sets are non-hunting or semi-
hunting gears. With this type of gear the
pinion and ring gears must be aligned
correctly. There will be two teeth marked on
the ring gear and one tooth marked on the
pinion gear. The one tooth on the pinion gear
must be installed so that it is between the
two teeth on the ring gear. The gear ratios
are; 2.50, 2.70, 2.75, 3.25 and 3.00.
Pinion housing
1. If the rear pinion bearing was removed, install a
new bearing.
2. Install the bearing races into the pinion housing.
3. Place the pinion gear into the 3rd member.
4. Install the pinion housing onto the 3rd member.
5. Install the pinion bearing spacers, shims and front
bearing.
6. Install a spacer on the pinion shaft so that the
pinion nut can be installed and tightened.
7. While rotating the pinion shaft, tighten the pinion
nut to 100 ft-lbs.
8. Check the torque required to rotate the shaft. If
the torque is not between 6 -10 in-lbs. then the
bearings must be re-shimmed. Add or subtract
shims as required until the torque is within
specifications.

for
Differential Assembly
9. Reassemble the differential housing in reverse
order.
10. Place the ring gear onto the differential housing
matching the mark made during disassembly.
11. Install two of the ring gear bolts finger tight to align
the gear.
12. Press the ring gear onto the differential housing.
13. Install the ring gear bolts and cross tighten to 65-
80 ft-lbs.
14. If the differential bearings were removed, install
new bearings.
15. Place races onto the differential bearings and place
the differential assembly onto the 3rd member.
Position the assembly so that it is just touching
the pinion gear.
16. Install the bearing adjusting nuts making sure that
the nuts are not cross threaded. Position the nuts
so they are in contact with the bearing races.
