Input Shaft, Checking for Wear

Input Shaft, Checking for Wear






1 - Bearing A in the Input Shaft Cover

• After removing the input shaft cover, always replace bearing A

3 - Input Shaft Cover

• Checking

4 - Pistons

• Checking for wear

5 - Pressure Plate

• Checking for wear

8 - Lining Discs

• Check the version and number

11 - Input Shaft Cylinder

• Check running and sealing surfaces for wear.

• Checking for signs of wear on the lining discs

13 - Oil Pipe

• Checking for wear

Checking Pistons and Thrust Plate for Wear

- Remove pistons - 1 - from thrust plate - 2 -.





Check the Thrust Plate - 2 -:

- Check thrust plate running and sealing surfaces - arrow A - for wear.

- Check thrust plate running and sealing surfaces - arrow D - for wear.

• If running or sealing surfaces - arrow A - show grooves, scratches or scoring, thrust plate - 2 - must be replaced.

• If running or sealing surfaces - arrow D - show grooves, scratches or scoring, thrust plate - 2 - and pistons - 1 - must be replaced.

Checking the Pistons - 1 -:

- Check seal - arrow B - on outer piston circumference - 1 - for damage.

- Check running surface - arrow C - on interior piston circumference - 1 - on shaft.

• If seal - arrow B - is damaged or piston running surface - arrow C - shows grooves, scratches, scoring or uneven thickness from wear, piston - 1 - must be replaced.

Check Input Shaft Cylinder Running and Sealing Surfaces for Wear

- Check input shaft running and sealing surfaces - arrow A - for wear.





• Shaft seal in input shaft cover seals at this sealing surface - arrow A -.

• Light scoring from shaft seal is normal.

- Check the running surface - arrow B - of bearing A (ball bearing for input shaft) in the input shaft cover for wear.

- Check shaft seal - arrow C - for damage.

• If seal - arrow C - is damaged or shaft running surfaces - arrow B - or - arrow A - show deep scoring or grooves, entire input shaft must be replaced.

Check Inner Circumference of Input Shaft Cylinder for Scoring from Lining Discs.

- Check inner circumference of input shaft cylinder for scoring from lining discs - arrows -.





• If there is scoring on interior circumference of input shaft cylinder from lining discs - arrows -, entire input shaft must be replaced.

Checking Oil Pipe for Wear

- Check oil pipe seal - 1 - for damage.





• The seal must have a gap - arrow B -.

• If the gap - arrow B - is completely closed, oil pipe must be replaced.

- Check oil pipe running surfaces - arrows - and rotor blades - arrow A - for wear and damage.

• If seal - 1 - or rotor blades - arrow A - are damaged or contact surfaces - arrow - show deep scoring or grooves, oil pipe must be replaced.

• The O-ring - 2 - must be replaced.

- Check the contact surface on the oil pipe in the suction jet pump. Refer to => [ Chain, Disc Set I and II, Bearing C and Suction Jet Pump, Checking for Wear ] Chain, Disc Set I and II, Bearing C and Suction Jet Pump, Checking for Wear

Check the Number and Version of the Lining Discs.





Depending on the version of the transmission as well as the type of complaint, the following changes can be made:

• Exchange the input shaft lining discs set from 6 lining discs to the newer 7 lining discs version.

• Exchange the input shaft lamellae set with rectangular-shaped pattern - A - for a newer version with trapezoidal-shaped pattern - B -.





Check the Input Shaft Cover

- Check the sealing surface on the cover - arrow - and the cover for damage.





• The sealing surfaces must not show any damage.

• Input shaft cover must not be broken cracked.

- If the sealing surface or the cover are damaged, then replace the input shaft cover.
