¹⁾ Replace the bolts that connect the transmission to the engine. ²⁾ Bolt class 10.9.

Procedure

NOTE:

Replace bolts which have been tightened to torque.

Replace self-locking nuts and bolts as well as sealing rings, seals and O-rings.

Secure all hose connections with hose clamps appropriate for the model. Refer to parts .

During installation, all cable ties must be re-installed at the same location.

-- Clean the transmission input shaft splines and damper unit splines on the flywheel, remove corrosion and apply a very thin coating of Clutch Disc Connection LubricantG 000 100 on the splines. Remove all excess grease.

-- Make sure the alignment sleeves -A- for centering the engine and transmission in the cylinder block are present. Insert the alignment sleeves if they are missing.
