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 TDC on No.1 cylinder [1] .
- Ensure No.1 cylinder camshaft lobes are facing upwards [2] .
- Ensure timing marks on both camshafts aligned [3] .
- Camshaft rotation can be prevented by using camshaft holding tool.
- Remove tensioner assembly before carrying out engine repairs [4] .
- Install tensioner after repairs. Tightening torque: 40 Nm.
- Ensure grooves [5] on sprockets of balancer shafts [6] are horizontal and pointing towards guide sprocket [7] .
