REP-TAT-P-1131-02 Install intake camshaft
- Clean all bearing positions and coat with motor oil.
- Clean all bearing positions of intake camshaft bearing caps (E1) (E2) (E3), (E4) (E5) (E6) and (E) coat with motor oil.
- Clean all bearing positions of the intake camshaft and coat with motor oil.
- Check all the roller cam followers (1) of the intake side for correct fit.
- Insert intake camshaft (2) in the bearing brackets in such a way that the mark (1) points towards the top.
- Check fitting sleeves (1) of the thrust bearing for damage, replace if necessary.
NOTE:
RISK OF DAMAGE
Engine damage caused by incorrectly installed bearing shells and bearing brackets.
Engine damage may result from incorrectly installing bearing shells and bearing brackets.
Engine damage caused by incorrectly installed bearing shells and bearing brackets.
Engine damage may result from incorrectly installing bearing shells and bearing brackets.
- Always install all bearing shells and bearing brackets in the same position from which they were removed.
- Coat all the intake camshaft bearing caps (E1) till (E6) and lay the bearing caps for the thrust bearing (E) with motor oil.
- 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 .
NOTE:
TECHNICAL INFORMATION
The camshaft is tensioned by the valve springs. Tighten or loosen each screw on the camshaft bearing caps one at a time in the specified sequence and by half a turn only. Repeat procedure.
