Attention! A T.Av. mandrel is required to complete the job. 1331 to install boot bearing.
Pic. 4.52. CV joint type GL 69 («tripod»): 1 – dirt protection ring; 2 - support ring; 3 - holder; 4 - corrugated cover; 5 - three-spike; 6 - retaining ring; 7 - drive shaft
When working, be guided by Fig. 4.52.
Operating procedure:
- remove the drive shaft;
- remove the retaining spring ring that secures the hinge to the shaft;
- mark the position of the hinge on the shaft;
Pic. 4.56. Removing the hinge from the drive shaft
- press the joint off the shaft using a puller (pic. 4.56). Do not rest the legs of the puller on the rollers, as they may be deformed;
- remove the bellows together with the bearing and the mudguard in the same way as the hinge;
Pic. 4.57. Position of the hinge boot GL 69 on the drive shaft (the arrow shows the groove on the shaft for installing the puller)
- for exact location on the shaft, the bearing of the new boot must be pressed onto it until the dimension L = is obtained (118±0,2) mm between the rear end of the bearing and the end of the shaft (pic. 4.57). This dimension is obtained by using a T.Av. 1331 when its end is flush with the end of the shaft;
Note. To prevent deformation of pressure sealed bearings and therefore grease leakage, do not press the bearing with a hammer, use a press so that the applied force can be gradually increased.
- for pressing, hold the shaft by the groove with a puller and install it on the shaft according to the marks made;
- after pressing, check the smooth movement of the hinge in all planes;
- fix the hinge with a retaining ring, installing it in the groove of the shaft;
- fill equally with grease from the tube attached to the boot the hinge body and the cavity of the boot.
