To Dismantle

For removing the output shaft, follow the description for dismantling of the gearbox up to the point where the output shaft has been removed. Then continue dismantling as follows:





1. Secure fixture 87 90 446 in a vice and place the output shaft in the fixture. Use spanner 87 90 453 to remove the nut.





2. Set up the bearing housing in a press in tool 83 90 098 and press the shaft out of the bearing housing.





3. Then use tools 87 90 636 and 87 90 651 to press off the rear roller bearing. For an output shaft with a final drive ratio of 9:33 as from the 1982 model (gearbox No. 436501), use holder ring 87 91 097.





4. Use tools 83 90 098, 83 90 106 and 83 90 148 to press the outer races of the taper roller bearings out of the bearing housing (see figure).
