Timing Chain: Service and Repair
Changing The Timing Chain (In Situ)
To remove (in car)
1. Rinse the car and remove the belt circuit cover.
2. Lower the car and remove upper engine cover.
1. Remove the ignition discharge module and spark plugs.
4. Detach the crankshaft ventilation pipe and hose. Cut the cable tie holding the non-return valve. Unplug the boost pressure control valve and
remove the camshaft cover.
2. The the crankshaft clockwise until the crankshaft and camshafts are aligned with their setting marks.
3. Check chain wear by removing the chain tensioner plug complete with spring and locating pin, and remove the chain tensioner without changing
the position of the piston.
The protruding part of the chain tensioner must not be longer than 15 mm. If it is, the chain must be changed.
4. Check the wear on chain sprockets and chain guide.
Chain guide wear must not be so great that the chain acts on the surface between the outer tracks.
If the surface between the outer tracks shows signs of wear, they must also be replaced and the chain changed in the usual manner.
To fit (in car)
1. Stuff a cloth in the area round the chain and also secure the chain with cable ties on both sides.
