NOSPIN DIFFERENTIAL TEST
(Before Installation)
After the NoSpin differential has been assembled
and before it is installed in the machine, make a test
of the operation of the differential as follows:
1. Install the NoSpin differential in the case.
2. Put the case in a stand or a vise to keep it from
rotation.
3. Install both axles in the case.

1. Case. A. Axle. B. Axle.
Put a force in a clockwise direction on both axles.
Keep the force on axle (A) and turn axle (B) in a
counterclockwise direction. A small noise will be
heard in the NoSpin differential and axle (B)
will turn freely.
NOTE: Make sure the force is kept on axle (A).
6. Keep the force on axle (A) and turn axle (B) in a
clockwise direction. A small noise will be heard
in the NoSpin differential and axle (B) will not
turn any farther.

both axles.
8. Keep the force on axle (A) and turn axle (B) in a
clockwise direction. A small noise will be heard
in the NoSpin differential and axle (B) will turn
freely.
NOTE: Make sure the force is kept on axle (A).
9. Keep the force on axle (A) and turn axle (B) in a
counterclockwise direction. A small noise will be
heard in the NoSpin differential and axle (B)
will not turn any farther.
10. Do Steps 4 through 9 again, except now hold axle
(B) and turn axle (A).
If the NoSpin differential does not have the cor-
rect action, inspect the components and check the
assembly procedure.
