NoSpin Differential
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 rotating.3. Install both axles in the case.
Test Procedure For NoSPIN Differential
(1) Case. (A) Axle. (B) Axle.4. Put a force in a clockwise direction on both axles.5. 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. 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.
NoSPIN Differential Test7. Put a force in a counterclockwise direction on 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. 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. Perform Steps 4 through 9 again, except now hold axle (B) and turn axle (A).If the NoSPIN differential does not have the correct action, inspect the components and check the assembly procedure.
