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] .
- Install camshaft retaining tools to LH and RH banks [2] .
- Ensure timing marks on camshaft gears aligned [3] & [4] .
- Ensure balancer shaft timing mark aligned at 12 o’clock position [5] .
- Remove tensioner assembly before carrying out engine repairs [6] .
NOTE: Bolts for camshaft sprocket MUST be renewed.
- Tighten bolt of each camshaft sprocket to 18 Nm [7] .
- Install tensioner after engine repairs [6] . Tightening torque: 80 Nm.
- Tighten crankshaft pulley bolt [8] . Tightening torque: 200 Nm + 90° + 90°.
