Pressing out a bearing from an elastic support
1 – strip A.40005/2; 2 – paws A.40005/11; 3 – puller A.40005/4; 4 – paws; 5 – elastic support
1. Apply marks (with paint or core), determining the relative position of the separated parts in order to connect them during assembly in the same position and maintain the shaft balancing unchanged.
2. Place the front propeller shaft in a vice. Remove the retaining rings.
3. Press out bearing housings 1 from cardan joint fork 2 using tool 3 (clamp 67.7823.9522) or a punch with a hammer.
4. In the new design of joints, it is impossible to press out needle bearings in this way due to the increased thickness of the joint fork.
Pressing out the bearing housing
5. Install the cardan shaft of one of the cardan joint forks on the press support 1. Using the special bushing 2, move the other fork 3 of the joint down with the press rod until it stops against the crosspiece 4.
6. Having turned the hinge fork by 1800, repeat the above operations, i.e. move the other end of the fork down until it stops in the crosspiece. When performing these operations, the opposite bearing of the crosspiece 2 will partially come out of the fork hole and it will be possible to install the bushing 1 with a side cutout in the resulting gap between the fork and the crosspiece.
7. Install bushing 1 on the crosspiece tenon, move the hinge fork down until bearing 2 is pressed out.
8. Using the above techniques, press out the other crosspiece bearings.
9. Loosen the nut securing the fork 3 of the cardan joint to the front shaft 4. Remove the fork using tool 1 (puller A.40005/1/5) (2 – puller levers).
10. Under a press, using half-rings 3, remove the intermediate support 2 from the front shaft 1 together with the bearing and dust deflector (4 – press punch).
11. To disassemble the intermediate support, remove the retaining ring 1 (2 – bearing, 3 – elastic support).
12. Then, using puller A.40005/2/4/11, press the bearing out of the support (see fig. Pressing out the bearing from the elastic support).
13. Disassemble the rear shaft using the techniques described above.
