Pressing in the locking ring of the axle shaft bearing
1 - mandrel А.74107/2R; 2 – a locking ring of the bearing; 3 - bearing mounting plate and oil deflector assembly with gasket; 4 - support ring А.74107/1R; 5 - axle shaft; 6 - bearing; 7 - clip A.74107 / 4R
Checking the force with which the axle shaft bearing locking ring is pressed out using tool A.95601 / R and a torque wrench
1 - indicator; 2 - axle shaft; 3 - fixture А.95601/R; 4 - torque wrench; 5 - ball bearing; 6 – a locking ring of the bearing
1. Place the axle shaft vertically, resting it with the flange on the ring 4 (see fig. Pressing in the locking ring of the axle shaft bearing) (А.74107/1R) fixtures.
2. Install the semi-axle bearing oil slinger and the bearing mounting plate with gasket, which are pre-connected with two screws, on the axle shaft; Install the half shaft ball bearing.
3. Insert a new locking ring into a special holder 7, put it in an oven and heat the ring to approximately 300°C so that at the time of pressing onto the axle shaft its temperature is 220–240°.
4. Press the locking ring on the axle shaft with mandrel 1 on the press with a force not exceeding 58800 N (6000 kgf) so that the inner ring of the bearing is sandwiched between the locking ring and the shoulder of the axle shaft.
5. After pressing on, make sure that the ring does not move under an axial load of 19600 N (2000 kgf). For this purpose, install the axle shaft assembly on tool A.95601 / R (see fig. Checking the force with which the axle shaft bearing locking ring is pressed out using tool A.95601 / R and a torque wrench) and clamp the locking ring in a special vise.
6. Attach the indicator leg, with a division value of 0.01 mm, to the axle shaft flange. After setting the indicator pointer to "0" apply the specified axial load using a torque wrench with a tightening torque of 78.4 - 83.3 N·mm (8–8.5 kgf·m) on the fixture screw. The screw through the ball rests against the end of the axle shaft. In this case, even the smallest gap between the locking ring and the inner ring of the bearing should not appear.
7. After removing the load and when unscrewing the screw of the device, the indicator arrow should return to the zero position; this proves that no shift has occurred between the snap ring and the axle shaft. If the indicator needle does not return to the zero position, then the locking ring has shifted and the axle shaft assembly must be replaced with a new one.
