How to check the differential of MN MODEL MN38 RC CAR?

Check the fit between the planetary gear shaft and the housing hole and the inner hole of the planetary gear. The planetary gear shaft and the gear should be clearance fit, and they need to be replaced when they are severely worn. At the same time, there should be no warping when the planetary gear shaft is placed in the differential housing bearing hole.

MN MODEL MN38 RC CAR Ensure that the contact surface of the driven bevel gear and the differential housing is in full contact without gap or looseness.

MN MODEL MN38 RC CAR The working surfaces of the planetary gears and the axle gears should not have obvious peeling and burning, otherwise they need to be replaced.

Use a vernier caliper or other measuring tools to measure the meshing clearance between the planetary gears and the axle gears. Too large or too small a clearance may affect the normal operation of the differential.
