Shown below is a set of instructions on how to properly install a NoSPIN
®
differential into a new Spicer
®
wheel differential
assembly. It is important to follow the procedure to insure a proper repair.
Disassembly
1. With the carrier assembly removed from the
drive axle housing, mount the carrier in a head
stand if available.
2. Before we start to disassemble the carrier, we
need to measure the ring gear backlash. We will
be resetting the backlash to this setting when we
reassemble the carrier.
3. Remove the carrier caps and fasteners. Remove
the wheel diff and gear assembly.
4. We can now remove the ring gear from the diff
case. Start by removing the ring gear bolt with
an impact gun.
5. The ring gear is press fit to the diff case, so we
need to use a press to separate them. Reinstall
two of the ring gear bolts and turn until you get
three to four threads engaged. Support the ring
gear on two sides. Now press down on one of
the bolts to move the case a small amount. Turn
the assembly 180° and repeat the process.
Important Note:
Do not press on the wheel diff
shaft to separate these parts. Even a slight bend
in the shafts will cause premature wear to the
differential gearing.
