Camshafts Or Camshaft Bearing, Removing And Replacing On Cylinder Bank 2 (Left): Installing
- Secure crankshaft in "TDC" position using Crankshaft Holder 3242.
-- Mount the Camshaft Fitting Tool - 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.
The camshaft thrust bearings and the bearing cap for cylinder bank 2 are marked after work is performed on the exhaust side to prevent them from being installed incorrectly:
| Cylinder Bank 2 (left) | |
|---|---|
| L1/L1 | Front |
| L2/L2 | Front in the center |
| L3/L3 | Rear in the center |
| L4/L4 | Rear |
-- Lay the camshafts thrust bearings "I, II, III" on the cylinder head.
- The cylinder head oil openings -arrow 1- must flow into the thrust bearing oil channels -arrow 2-.
-- Lay the camshaft thrust bearing "IV" on the cylinder head.
- Both alignment sleeves -arrows- must be inserted into the openings on the thrust bearing.
- The alignment sleeves must engage in the openings in the cylinder head.
-- Check the installation direction of the thrust bearings:
- The round edge -arrow 2- points towards the intake side.
- The cornered edge -arrow 1- points towards the exhaust side.
-- Place the camshafts in the "TDC" position in the thrust bearings.
- The intake camshaft -2- must be able to be stopped with the Camshaft Adjustment Pins T40060.
- The bolt -arrow- in the Camshaft Adjustment Pins T40060 must be perpendicular to the center axis of the camshaft.
- The exhaust camshaft -1- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.
-- Apply the appropriate bearing cap to the corresponding thrust bearing.
-- Loop a cable tie -arrows- on the right and left around the thrust bearing and the bearing cap and tighten them.
-- Install the bolts -1 to 12- in the bearing cap.
-- Install the Locking Device-Locking Pin T40311/1 in the threaded hole -1- at the level of the 5-cylinder, as shown in the illustration.
-- Install the Locking Device T40311 on the mounting bracket -arrows- for the tension claws, as shown in the illustration.
-- Tighten the bearing cap bolts, refer to Figure.
-- Remove the Locking Device T40311 and the Locking Device-Locking Pin T40311/1.
-- Check the camshaft "TDC" position:
- The intake camshaft -2- must be able to be stopped with the Camshaft Adjustment Pins T40060.
- The bolt -arrow- in the Camshaft Adjustment Pins T40060 must be perpendicular to the center axis of the camshaft.
- The exhaust camshaft -1- 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 Camshaft Fitting Tool - T40096.
-- Install the camshaft timing chains, refer to Installing .
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.
