Valve timing procedures
Removal
- Removal/installation of timing chain(s) requires:
- Engine removal.
- Sump removal.
- Engine at TDC on No.1 cylinder [1] .
- Ensure camshaft lobes for No.1 cylinder angled upwards [2] .
- Install camshaft locking tool [3] .
- If camshaft locking tool cannot be installed, turn crankshaft 360°.
- Remove timing chain tensioner [4] .
NOTE: Mark direction of rotation on chains.
- Remove chain guide [5] .
- Remove upper timing chain.
- Slacken intermediate shaft sprocket bolt 360° [6] .
NOTE: Hold crankshaft pulley with crankshaft pulley holding tool.
- Remove timing chain tensioner [7] .
- Remove intermediate shaft sprockets and lower timing chain.
Installation
- Engine at TDC on No.1 cylinder [1] .
NOTE: Ground tooth on crankshaft sprocket aligned with rear main bearing joint [8] .
- Install intermediate shaft rear sprocket (large diameter) and lower timing chain [9] .
- Ensure intermediate shaft sprocket timing marks aligned [10] .
- Install intermediate shaft front sprocket (small diameter) [11] . Finger tighten bolt [6] .
- Reset lower timing chain tensioner [7] :
- Release locking mechanism [12] . Use screwdriver.
- Push tensioner rail against chain tensioner [13] .
- Install timing chain tensioner [7] .
- Tighten tensioner bolts [14] . Tightening torque: 8 Nm.
- Tighten intermediate shaft sprocket bolt [6] . Tightening torque: 60 Nm + 90°.
NOTE: Hold crankshaft pulley with crankshaft pulley holding tool.
- Fit timing chain to camshaft sprockets ensuring copper coloured chain links aligned with timing marks [15] & [16] .
- Fit timing chain to intermediate shaft front sprocket (small diameter) ensuring copper coloured chain link aligned with timing mark [17] .
- Install chain guide [5] .
- Remove camshaft locking tool [3] .
- Push tensioner blade against chain [18] .
- Turn crankshaft 2 turns clockwise to TDC on No.1 cylinder [1] .
- Ensure camshaft lobes for No.1 cylinder angled upwards [2] .
- Ensure camshaft locking tool can be fitted [3] . If not, repeat installation procedures.
NOTE: Coloured links may not be aligned.
