Camshafts, Removing, Used Camshafts, Reinstalling On Cylinder Bank 1 (Right): Installing
- Secure crankshaft in "TDC" position using :3242 .
-- Mount the :T40096 onto the teeth of the intake camshaft so that one arm of the clamping tool engages in one sprocket half.
- The wider arm must engage into the wider half of the sprocket.
-- Tension the tensioning tool with the thumb wheel until the tooth faces align.
-- Lay the camshafts and the camshaft bearings that are tied up with cable ties -arrows- onto the cylinder head.
The cable ties prevent the camshafts and the camshaft bearing from tilting when they are being tightened.
-- Check the camshaft "TDC" position:
- The intake camshaft -1- must be able to be stopped with the :T40060 .
- The bolt -arrow- in the :T40060 must be perpendicular to the center axis of the camshaft.
- The exhaust camshaft -2- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.
-- Remove the : T40060 .
-- Screw in two camshaft chain sprocket bolts with five turns each into the threaded openings of the camshaft as shown in the illustration.
-- Attach the :T10172 with the :T10172/5 to both of the bolts and turn the camshafts approximately 30° counterclockwise in direction of -arrow- until the groove -arrow A- in the camshaft points vertically towards the cylinder head sealing surfaces -arrows B-.
There is a risk of causing damage to the valve.
- Do not turn the camshaft further than indicated.
-- Check the installed location of the alignment sleeves:
- Both alignment sleeves -arrows- must be inserted into the openings on the thrust bearing "IV".
- The alignment sleeves must engage in the openings in the cylinder head.
-- Install the bolts -1 to 12- in the bearing cap.
-- Install the :T40311 on the mounting bracket -arrows- for the tension claws, as shown in the illustration.
-- Tighten the bearing cap bolts. .
-- Remove the :T40311 .
-- Attach the :T10172 and the :T10172/5 to both of the bolts and turn the camshafts approximately 30° clockwise -arrow- until the groove -arrow A- in the camshaft is above the opening -arrow B- for the :T40060 .
-- Check the camshaft "TDC" position:
- The intake camshaft -1- must be able to be stopped with the :T40060 .
- The bolt -arrow- in the :T40060 must be perpendicular to the center axis of the camshaft.
- The exhaust camshaft -2- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.
Install in reverse order of removal. Note the following:
-- Remove the :T40096 .
-- Install the camshaft timing chains. Refer to CAMSHAFT TIMING CHAIN, REMOVING FROM CAMSHAFTS .
Risk of damaging valves and piston heads after working on valve train.
- The motor must not be started for about 30 minutes after installing camshafts because the hydraulic equalization elements must seat themselves.
- To ensure valves do not strike pistons when starting, carefully rotate engine at least two full revolutions.
