- During removal/installation of timing chain:
- Align dark coloured chain links with marks on sprockets [3] .
- To check chain movement:
- Prevent crankshaft rotation.
- Apply torque to camshaft sprocket in clockwise direction – 41 Nm (cylinder heads installed), or 20 Nm (cylinder heads removed).
- Hold ruler along edge of chain.
- Apply torque to camshaft sprocket in anti-clockwise direction – 41 Nm (cylinder heads installed), or 20 Nm (cylinder heads removed).
