How to check the differential of MN MODEL MN91 RC CAR?

Check the fit between the planetary gear shaft of MN MODEL MN91 RC CAR and the housing hole and the inner hole of the planetary gear. Make sure that the planetary gear shaft is not warped during installation to avoid affecting the normal operation of the differential.

Carefully check the contact surface of the differential case of MN MODEL MN91 RC CAR to ensure that the contact surface of the driven bevel gear and the differential case can be fully contacted without looseness or clearance.

Check the working surface of the planetary gear and the axle gear of MN MODEL MN91 RC CAR to ensure that there is no significant peeling and burning.
If the damage is found to exceed 1/4 along the tooth height or 1/5 along the tooth length, the relevant gear should be replaced immediately.

By checking the meshing clearance of the planetary gear and the axle gear of MN MODEL MN91 RC CAR, you can understand their wear.
If the meshing clearance is too large, it means that the gear has been severely worn and needs to be replaced with a new gear.

By checking the planetary gear shaft and housing hole, the contact surface of the differential case, the working surface of the planetary gear and the axle gear, and the meshing clearance between the planetary gear and the axle gear, we can fully understand the operating status of the MN MODEL MN91 RC CAR differential and find and solve problems in time.
