- 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 - arrow - 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 C must be replaced.
- Check the running surface on the disc set I.
Checking the Suction Jet Pump
• Input shaft removed. Refer to => [ 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.
