Valve timing procedures
Removal
- Removal/installation of timing chain requires:
- Sump removal.
- Ensure crankshaft sprocket keyway at 7 o’clock position [1] .
- Ensure timing mark on RH inlet camshaft sprocket at 1 o’clock [2] .
- Ensure timing mark on RH exhaust camshaft sprocket at 8 o’clock [3] .
- Release RH tensioner ratchet [4] .
- Compress tensioner plunger [5] .
- Retain in position with wire clip [6] .
- Remove RH chain tensioner [7] , RH tensioner rail, RH chain guide and RH chain.
- Turn crankshaft clockwise until crankshaft keyway at 11 o’clock position [8] .
- Ensure timing mark on LH inlet camshaft sprocket at 9 o’clock [9] .
- Ensure timing mark on LH exhaust camshaft sprocket at 2 o’clock [10] .
NOTE: Coloured links may not be aligned.
- Release LH tensioner ratchet [4] .
