Valve timing procedures
Removal
- Remove crankshaft position (CKP) sensor.
- Turn crankshaft in direction of engine rotation until crankshaft timing pin can be installed [1] .
- Ensure crankshaft sprocket keyway at 6 o’clock position [2] .
NOTE: If crankshaft sprocket keyway at 9 o’clock position, replace drive plate.
- Ensure groove in rear of camshafts positioned as shown [3] .
- Remove RH bank timing chain tensioner and tensioner blade.
- Slacken bolts of each RH bank camshaft adjuster [4] .
- Remove RH bank camshaft adjusters and timing chain.
- Remove LH bank timing chain tensioner and tensioner blade.
- Slacken bolts of each LH bank camshaft adjuster [5] .
- Remove LH bank camshaft adjusters and timing chain.
NOTE: Crankshaft sprocket friction washers MUST be replaced [6] .
Installation
