Install intake camshaft
- Check the fitting sleeves (1) for correct seating and damage and replace if necessary.
- Coat all bearing positions (1) with fresh motor oil.
- Clean all bearing positions of the intake camshaft bearing cap (El), (E2), (E3), (E4) and (E) and coat with motor oil.
- Clean all the bearing positions (arrows) of the intake camshaft (1) and coat with motor oil.
- Before installing the intake camshaft, check the correct seat of the roller cam follower (1).
- Coat the roller came follower (1) with fresh motor oil.
- Insert the Intake camshaft (1) Into the cylinder head h such a way that the mark (2) point up.NOTE: TECHNICAL INFORMATION
The camshaft bearing caps must not be mixed up. The camshaft bearing caps must be installed in the installation position from which they were removed. - Position the intake camshaft bearing cap on the cylinder head.NOTE: The intake camshaft bearing caps are legibly labeled from the intake side with E1, E2, E3, E4 and E.NOTE: Intake camshaft bearing cap E is a thrust bearing.
- Check the tensile strength of the screws for the bearing cap.
The illustration shows the screw with a tensile strength of 8.8.
- Check the tensile strength of the screws for the bearing cap.
The illustration shows the screw with a tensile strength of 10.9.

The camshaft is under tension due to the valve springs. Tighten or loosen each screw on the camshaft bearing caps in the prescribed sequence only by half a turn. Repeat procedure. - Press down the intake camshaft bearing cap and step-wise apply the screws in the order (1) to (10) until hand-tight.
- Join the screws in sequence (1) to (10) in half turns.
- Observe the joining torque.
- Tighten all screws in the sequence from (1) to (10).TIGHTENING TORQUES SPECIFICATION
