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.

1. Press a new plain half bearing cone on to the
plain half diff case. Use an old bearing cup as a
press tool.

2. Install the inner thrust washer. Apply oil to each
side.
3. We can now install the NoSPIN assembly. Make
sure the wing nut holding the NoSPIN together is
facing up; this will make it easier to remove
later in the procedure.
4. The differential top plate can now be installed
over the NoSPIN. Remember the bolt holes are
not symmetrical, so the plate only fits one way.
5. Lay the diff assembly on its side to install the
new top plate bolts. This will keep the top plate
in place until you get the bolts started by hand.
Important: Do not remove the wing nuts holding the
NoSPIN together. It must be installed into the diff
case fully compressed.
Caution: There are two springs in the NoSPIN
assembly that are compressed and under pressure.
Removing the NoSPIN restraining system before it’s
installed into the diff case may cause injury.

6. With an impact gun, snug the bolts in a criss-
cross pattern. We’ll be torqueing these bolts later
in this procedure.
9. To make assembly easier, put the diff assembly
in a press with the alignment dowels at 3:00 and
6:00 o’clock.

7. We can now install the two new alignment
dowels. Use a press or hammer to fully seat
them in the top plate.
8. Install the thick thrust washer to the NoSPIN. Oil
both sides.
10. The ring gear can now be lowered on to the diff
with the dowel pins in alignment. Before we
press the gear to the diff case, we want to start
all the ring gear bolts by hand, engaging a
couple of threads.
11. Slowly press the gear in place. Having the ring
gear bolts installed will guide the ring gear,
keeping it from misaligning during the press.

All applications must be approved by the Application Engineering Department. Specifications and/or design are subject to change without notice or obligation.

12. With the ring gear fully seated to the diff case,
we can snug the ring gear bolts with an impact
gun in a crisscross pattern.
13. With the assembly still in the press, apply
enough load so the assembly won’t turn while
torqueing the ring gear bolt. In a crisscross
pattern, torque to 435-465 ft. lbs. (589-630 Nm).
14. Now turn the assembly over in the press so we
can torque the plain half case bolts. Again, apply
enough pressure to keep the diff from rotating
while torqueing the bolts to 180-220 ft. lbs
(242-298 Nm).
15. The last step is to remove the wing nuts that
were holding the NoSPIN together. Remove the
threaded rod and washers.

carrier reassembly, go to Media.SpicerParts.com
