General precautions
- Disconnect battery earth lead.
- Remove spark plugs to ease turning engine.
- Turn engine in normal direction of rotation (unless otherwise stated).
- Observe tightening torques.
- Do NOT turn crankshaft via camshaft or other sprockets.
- Do NOT turn crankshaft or camshaft with timing chain removed.
Valve timing procedures
NOTE: Timing chain can be changed without dismantling engine. Using the tools listed above, the new chain can be linked to the old, passed round the sprockets and then joined.
- Engine at 55° BTDC on No.1 cylinder.
NOTE: Use 305° mark on crankshaft pulley [1] .
- Remove camshaft position (CMP) sensors [2] .
- Ensure timing marks on camshaft sprockets aligned [3] .
NOTE: Mark on each camshaft sprocket MUST align with centre of each camshaft position (CMP) sensor hole [3] & [4] .
- Turn crankshaft clockwise until crankshaft keyway at 12 o’clock position [5] .
- Ensure balancer shaft counterweight aligned with timing mark on crankcase [6] .
- With cylinder head front covers removed:
- Turn crankshaft clockwise to 40° ATDC on No.1 cylinder [7] .
- Ensure camshaft sprocket timing marks at 12 o’clock position [8.]
- Ensure timing mark on camshaft sprockets aligned with edge of cylinder head [9] .
- Fit new timing chain tensioner. Tightening torque: 70 Nm.
NOTE: Crankshaft pulley bolt MUST be renewed.
- Tighten crankshaft pulley bolt to 200 Nm + 90° [10] .
