Camshaft Seal, Removing And Installing
Special Tools And Workshop Equipment Required
- Puller - Camshaft Seal:T10443
- Assembly Tool:T10493
Procedure
-- Remove the toothed belt from the camshaft. Refer to TOOTHED BELT, REMOVING FROM CAMSHAFT .
The internal press piece of the :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 :T10443 until light resistance is felt.
-- Install the :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 Silicone Adhesive:D 176 501 A1 to seal the shaft seal.
-- Push the silicone adhesive evenly on the sealing lip of the shaft seal.
- The sealant bead must be applied evenly around the complete circumference.
-- Place the :T10493/1 on the camshaft as shown.
-- Carefully slide the shaft seal -1- over the guide sleeve and onto the camshaft.
- The guide sleeve remains on the camshaft as a stop while pushing the shaft seal in.
-- Press the shaft seal in as far as the stop using the :T10493/2 and :T10493/3 .
-- Install the toothed belt (adjust valve timing). Refer to TOOTHED BELT, REMOVING FROM CAMSHAFT .
