Removal And Installation: Camshaft: Installing
-- Remove any sealant still on the cylinder head and on the bearing frame with a rotating plastic brush.
-- Clean the sealing surfaces.
- Sealing surfaces must be free of oil and grease
-- Oil running surfaces of both camshafts.
Set up the Camshaft Fitting Tool T40094 for camshaft as follows:
-- Remove mounts -T40094/3-, T40094/4 and -T40094/5- from the base plate. Loosen the lower bolt.
-- Install the mounts -T40094/9- and -T40094/10- in the empty outer locations.
-- Install mount -T40094/2- in the position "A" and install the mount -T40094/1- in the position "F".
-- Insert the intake camshaft as shown. Make sure the indentation -arrow- for the cylinder head bolt faces outward.
-- Position the 0.50 mm feeler gauge and slide the mount -T40094/8- into the groove on the intake camshaft.
-- Secure the exhaust camshaft above the groove -arrow- with the -cover T40094/11-.
-- Position the Tensioning Tool T40096/1 on the exhaust camshaft sprockets.
-- Tension the Tensioning Tool T40096/1 with the thumb wheel until the tooth faces align. Use a 13 mm open-end wrench if necessary.
-- Slide the intake camshaft toward the exhaust camshaft until the splines mesh.
-- Mount the bearing frame on the camshafts.
- All the camshaft bearings must lie on the camshafts.
-- Position the Clamping Tool T40095 as shown and secure the camshafts in the bearing frame.
-- Remove the Cover T40094/11.
-- Remove the Mounts T40094/8 from the intake camshaft groove.
-- Cut the tube nozzle at the front marking (nozzle diameter: approximately 2 mm).
-- Apply a bead of sealant (approximately 2 to 3 mm side) -arrows- on the clean sealing surfaces of the cylinder head as shown.
Excess sealant could get on the camshaft bearings or seal off the oil supply holes.
- Do not apply sealant beads thicker than indicated.
- Make sure that excess sealant does not seal off the oil supply holes -arrow- for the bearing frame.
-- Remove the camshafts with the bearing frame and the Clamping Tool T40095 from the Camshaft Insertion Tool T40094.
-- Carefully insert the camshafts and bearing frame in the cylinder head.
-- Then tighten the bearing frame screws by hand in the sequence -1- to -24-.
- The guide frame must be touching the entire contact surface of the cylinder head.
-- Tighten the bearing frame bolts to 10 Nm in sequence -1- through -24-.
-- Remove the Clamping Tool T40095 and the Tensioning Tool T40096/1.
-- Replace the camshaft seal. Refer to CAMSHAFT SEAL .
-- Install a new sealing cover, -item 7-, onto the cylinder head with a suitable drift until it is flush.
Install in reverse order of removal. Note the following:
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 the crankshaft at least 2 turns.
-- Place the hub on the camshaft.
-- Tighten the hub bolt -1-. Use Counterholder T10051 to do so.
-- Push the camshaft sprocket onto the hub.
-- Install the bolts -1- into the camshaft sprocket by hand to eliminate play.
-- Secure the hub with the Locking Pin 3359.
-- Install toothed belt and adjust valve timing. Refer to Installing .
-- Install the vacuum pump. Refer to Installing .
-- Install the cylinder head cover. Refer to Installing .
-- Install the fuel filter. Refer to Description and Operation .
