Instructions for disassembly and assembly (transmission G 86)

Disassembly

Note When replacing the tapered roller bearings (No. 1 and No. 27), determine the installation position before removing the output shaft.





1. Press off the tapered roller bearing inner race. The outer race must be used for this purpose.


Assembly





1. Check the synchronizing rings for wear. To do this, press the ring into the shift sleeve and measure the gap dimension "a" with a feeler gauge in positions A, B and C. Add up the measured values and divide by 3. The value obtained must not be below 0.5 mm.





2. Insert the spring into the loose gear wheel so that the angled end engages in the hole.





3. Install the selector sleeves in the correct position. The slanted side (arrow 1) faces the reverse gear loose gear wheel (No. 2) in the case of the 5th and reverse gear selector sleeve, and it faces the 2nd gear loose gear wheel (No. 16) in the case of the 1st and 2nd gear selector sleeve.
4. Determine the snap ring for the tapered roller bearing. To do this, determine the thickest ring which can still just be used.





Note Determine the snap rings of the synchronizing elements and of the 3rd and 4th gears in exactly the same way.





5. Arrangement of the snap rings

Note The snap rings 1, 2, 4, 5 and 7 must be determined again. The snap rings 3 and 6 always have the same thickness.

3 = 2.5 mm thick
6 = 2.0 mm thick
