TIMING SYSTEM DRIVE CHAIN - R.R

1. Move the timing chain hydraulic tensioner to operating position by exercising overall pressure by hand on the chain in the area shown in the figure. This puts the chain under tension, which in turn acts on the mobile pad to release the mobile tensioner piston.

When the piston is activated the spring will make a noise.

TIMING SYSTEM DRIVE CHAIN - R.R

If the chain remains slack, the tensioner is not in the operating position.

- Rotate the crankshaft through 720°, then turn the crankshaft until cylinder 4 is at TDC in the combustion phase, white notch stamped on the timing chain toothed drive pulley turned down and key upward.

When the crankshaft is rotated the tensioner piston should follow the chain during the rotation stage.

- Check the timing making sure that the timing references correspond.
