Here, you must observe the following:
• Seals (such as O-rings, shaft seals, gaskets and filters) must always be renewed.
• All O-rings, rectangular-section rings, and other sealing rings must always be lubricated
with white petroleum jelly before installation.
• All bearings must always be in a slightly oiled condition when installed.
• For transmissions that have been used for a large number of kilometers
(> 80,000 km), all lined clutch discs and steel discs must be replaced.
• After clutches/ brakes have been damaged, the converter, oil tubes, and oil
cooler, must be cleaned thoroughly.
• If brake F has been damaged, or if a considerable distance has been covered
(> 150,000 km), piston F must be replaced.
