Procedure 

-- Remove the toothed belt from the camshaft. Refer to TOOTHED BELT, REMOVING FROM CAMSHAFTS .

TIP:

The internal press piece of the Puller - Camshaft Seal: T10443  is loosened from the pressure bolt if it is turned backward too far. Then the press piece must be pushed back onto the pressure bolt.

-- Carefully turn back the threaded pin -arrow- of the Puller - Camshaft Seal: T10443  until light resistance is felt.

-- Install the Puller - Camshaft Seal: T10443  as shown, and then lock it into place with the threaded pin -A-.

-- Install the pressure bolt -B- until the shaft seal is pulled out.

-- Clean the running and sealing surfaces completely of oil residue with degreasing agent.

-- Clean the sealing lip of the new shaft seal over the complete outer circumference (removing the wax layer) with degreasing agent.

TIP:

Use the Silicone Adhesive D 176 501 A1 to seal the outside of the shaft seal.

-- Apply the evenly proportioned silicone adhesive on the outer sealing lip of the shaft seal.

• The sealant bead must be applied evenly around the complete circumference.
