GM Hydraulic Throwout Bearing Assembly Method
Because bearings are high-precision products, improper assembly can easily cause damage to the bearing grooves and lead to bearing damage. The jeep tj throwout bearing should be assembled with special molds, and should not be knocked at will. Only small circles can be pressed into the shaft, and only large circles can be pressed when pressing large circles. When assembling, air pressure or hydraulic pressure should be used, and the upper and lower die should be horizontal when press-fitting.
