Cross section of the elastic coupling of the drive shaft
1 - drive shaft; 2 - centering sleeve; 3 - bolt; 4 - elastic coupling; 5 - washer; 6 - nut; 7 - gearbox flange
Installing the centering sleeve
1. Remove cardan transmission.
2. When reusing the flexible coupling, mark its position relative to the driveshaft flange.
3. After removing the bolts, remove the flexible coupling.
4. Place the driveline in a vice with soft metal jaws and drill a hole perpendicular to the axis with a diameter of 10 mm in the centering sleeve at a distance of approximately 15 mm from its outer end.
5. Insert a puller into the resulting hole (kernel), remove the bushing from the propeller shaft.
6. Clean the groove on the shaft, place the new bushing vertically in the hole and press it in completely with a mandrel.
7. Install the flexible coupling on the driveline flange, ensuring that the previously applied marks match. Put the bolts (heads towards the intermediate support) and screw on new self-locking nuts, tightening them with a torque of 4.5 kgf·m.
8. Install the driveline to the vehicle.
Note. Do not forget to put 6 g of refractory grease into the groove of the centering sleeve.
