for disc set ) ]

Check conical discs for disc set "II "





- Check if conical discs - arrow - for disc set " II" are smooth and show no signs of wear.

- To determine if there is damage to the running surface, run your finger nail from the inside to the outside over the entire surface of the conical disc.

• Very light wear grooves and damage cannot be detected to the finger touch.

• If wear grooves or damage is detected, then the transmission must be replaced.

- Also perform a visual test.

• The transmission must be replaced if there are single wear grooves which look polished (shiny), with black discoloration.

Checking running surface for bearing " G" for disc set "II"





• The running surface - 1 - for bearing "G" must be like new.

- To determine if there is damage to the running surface, run your finger nail from the inside to the outside over the entire running surface.

• Very light wear grooves and damage cannot be detected to the finger touch.

• If wear grooves or damage is detected, then the transmission must be replaced.

Check conical discs for disc set "I"





- Check if conical discs - arrow - for disc set " I" are smooth and show no signs of wear.

• Ignore - 1 and 2 -.

- To determine if there is damage to the running surface, run your finger nail from the inside to the outside over the entire surface of the conical disc.

• Very light wear grooves and damage cannot be detected to the finger touch.

• If wear grooves or damage is detected, the disc set "I" must be replaced.

- Also perform a visual test.

• The disc set "I" must be replaced if there are single wear grooves which look polished (shiny), with black discoloration.

Check running surfaces for bearing " C" and bearing "D" (roller bearing for disc set " I")





• Pay no attention to - arrow -.

• The running surfaces - 2 - for bearing "C" and - 1 - for bearing "D" must be like new.

- To determine if there is damage to the running surface, run your finger nail from the inside to the outside over the entire running surface.

• Very light wear grooves and damage cannot be detected to the finger touch.

• If wear grooves or damage is detected, the disc set "I" must be replaced.

Checking bearing "C" (roller bearing for disc set "I")





- Check bearing "C" - 1 - for damage.

• The roller bearing must not have any surface damage.

• The bearing cage must not have any cracks or breaks.

- To see if there is any damage on the roller bearings, run your finger nail over the entire running surface.

• Very light wear grooves and damage cannot be detected to the finger touch.

• If wear grooves or damage is detected, the bearing "D" must be replaced.

- Also check the running surface on the disc set "I" => [ Check running surfaces for bearing and bearing (roller bearing for disc set ) ].

Checking suction jet pump





• Input shaft removed => [ Input Shaft ] Input Shaft

- Through the opening in the transmission housing, check the contact surface - arrow - of the oil pipe in the suction jet pump for signs of wear, cracks or other damage.

• The oil pipe contact surface in suction jet pump - arrow - must not have any noticeable, cascaded scoring or scratches.

• In case of noticeable, cascaded scoring or damage to the wear surface by the oil pipe, suction jet pump must be replaced.

- Also check oil pipe => [ Input Shaft, Checking for Wear ] .

Checking chain





- Check is the chain bolt shows in its rear side still a convex shape with rounded corners - arrow A -.

- If the shape of the chain bolt has been worn down through wear or chain-slip to sharp edges - arrow B -, then the chain must be replaced.

- Also check the running surface of disc set "I" => [ Check running surfaces for bearing and bearing (roller bearing for disc set ) ] and disc set "II" => [ Check conical discs for disc set ]
