Assembly Instructions For Output Shaft

Information

All transmission parts, particularly synchronization parts, must always be coated with transmission oil before assembly. Avoid assembling dry parts.

Check triple-cone synchronization (1st gear) for wear. To do this, press the friction ring, cone ring and synchronizer ring onto the gear wheel and measure the gap dimension with a feeler gauge.

Installation dimension (new): 1.4 to 2.0 mm

Wear dimension: 0.6 mm
Check double-cone synchronization (2nd gear) for wear. To do this, press the friction ring and synchronizer ring firmly onto the gear wheel by hand and measure the gap dimension with a feeler gauge.

Check single-cone synchronization for wear.
- Push ring into shift sleeve.
- Measure gap dimension -a- with a feeler gauge in positions -A, B and C- .
- Add up the measured values and divide by three. The value obtained must not be less than 0.5 mm.

Determine the circlip for the taper roller bearing. To do this, determine the thickest ring that can still be used.

Determine the other circlips in the same way.
Information

The thickness of circlips 1, 2, 4, 5 and 7 must be calculated again. Circlips 3 and 6 always have the same thickness. Circlip 3 is 2.5 mm and circlip 6 is 2.0 mm thick.

Arrangement of the circlips:
