Figure 3-56. Pressing in the bearing and axle bearing retaining ring:
1 - half shaft;
2 - press table;
3 - ring from the fixture kit 67.7853.9571;
4 - bearing;
5 - bearing mounting plate and oil deflector assembly.
Insert the new locking ring into a special holder, place it in the oven and heat the ring to approximately 300°C so that when it is pressed onto the axle shaft its temperature is 220-240°C.
Press the locking ring onto the axle shaft using a press with a force no greater than 58.8 kN (6000 kgf) so that the inner bearing ring is clamped between the locking ring and the flange of the axle shaft.
After pressing, make sure that the ring does not shift under an axial load of 19.6 kN (2000 kgf). For this purpose, install the axle shaft assembly on a special device (figure 3-57), and clamp the locking ring in a special vice.
Figure 3-57. Checking the pressing force of the axle shaft bearing retaining ring:
1 - indicator;
2 - half shaft;
3 - device;
4 - torque wrench;
5 - bearing;
6 - bearing retaining ring.
Place the indicator leg 1 with a division value of 0.01 mm on the flange of the axle shaft. After setting the indicator pointer to "0", apply the specified axial load, creating a tightening torque of 78.5-83.3 Nm (8-8.5 kgf·m) on the screw of the device with a torque wrench. The screw rests against the end of the axle shaft through the ball. In this case, not even the smallest gap should appear between the locking ring and the inner ring of the bearing.
After removing the load and unscrewing the screw of the device, the indicator arrow should return to the zero position; this proves that there has been no shift between the locking ring and the axle shaft. If the indicator needle does not return to the zero position, the locking ring has shifted and the axle shaft assembly must be replaced with a new one.
After checking the pressing of the locking ring, install the plate and oil deflector mounting bolts 6 (see figure 3-56) and secure them by bending the bolt holders inward.
