- Remove the ignition coil. Refer to Ignition Coil Removal .
- Remove the camshaft cover. Refer to Camshaft Cover Removal .
- Remove the air conditioning compressor bracket. Refer to Air Conditioning Compressor Bracket Removal .
- Remove the camshaft position actuator solenoid valves. Refer to Camshaft Position Actuator Solenoid Valve Removal .
- Rotate the engine clockwise until the bore (2) in the crankshaft balancer aligns with the mark (1) on the engine front cover.
- Remove the crankshaft bearing cap tie plate hole plug (2) and the seal ring (1).
Caution: To ensure proper crankshaft top dead centre (TDC) alignment, the retention pin should fit easily through the bore in the crankshaft tie plate and into the crankshaft. Binding of the retention pin could affect proper engine timing.
- Install EN-952 fixing pin (1) in order to fix the crankshaft in TDC position.
- Loosen the inlet camshaft sprocket bolt (2) while holding up the hexagon of the inlet camshaft with a spanner (1) until the camshaft position exciter wheel is clearly rotatable.
- Loosen the exhaust camshaft sprocket bolt while holding up the hexagon of the exhaust camshaft with a spanner until the camshaft position exciter wheel is clearly rotatable.
Note: The fixing tool should be installed completely to both camshaft grooves without extreme effort.
- Adjust camshafts that EN-953-A fixing tool (1) can be installed.
- Remove 2 upper timing chain guide bolts (1).
- Remove upper timing chain guide (2).
Note: Push the fixing tool in the direction of the arrow to ensure it engages without clearance.
- Install EN-49977-200 fixing tool (2) and adjust that the gearing (1) of the fixing tool engages with the inlet camshaft sprocket gearing (1).
- Tighten the 2 fastening bolts (1) of EN-49977-200 fixing tool while pushing the fixing tool in direction of the arrow.
- Tighten the adjuster bolt (2).
Note: A wrong installation position is possible. Make sure that the fixation tool is installed without clearance to the cylinder head in areas (3) and (5).
- Install EN-49977-100 fixation (2) in order to find and fix the correct position of the camshaft position exciter wheels.
- Tighten the 3 fastening bolts (6) of EN-49977-100 fixation.
Caution: Refer to Fastener Caution in the Preface section.
- Tighten the intake camshaft sprocket bolt (4) while holding up the hexagon (1) of the intake camshaft to 50 N·m (37 lb ft).
- Tighten the intake camshaft sprocket bolt (4) while holding up the hexagon (1) of the intake camshaft to an additional 60°.
- Tighten the exhaust camshaft sprocket bolt while holding up the hexagon of the exhaust camshaft to 50 N·m (37 lb ft).
- Tighten the exhaust camshaft sprocket bolt while holding up the hexagon of the exhaust camshaft to an additional 60°.
- Remove EN-49977-100 transmitter disc fixation and EN-49977-200 fixing tool.
- Install upper timing chain guide (2).
- Install 2 upper timing chain guide bolts (1) and tighten to 8 N·m (71 lb in).
- Remove EN-953-A fixing tool.
- Remove EN-952 fixing pin.
- Rotate the crankshaft for 720° and check the engine timing again. Repeat the adjustment procedure if necessary.
- Install crankshaft bearing cap tie plate hole plug and seal ring and tighten to 40 N·m (30 lb ft).
- Install the camshaft position actuator solenoid valves. Refer to Camshaft Position Actuator Solenoid Valve Installation .
- Install the camshaft cover. Refer to Camshaft Cover Installation .
- Install the ignition coil. Refer to Ignition Coil Installation .
- Install the air conditioning compressor bracket. Refer to Air Conditioning Compressor Bracket Installation .
