While offering up the sprocket, hold the chain tight by finger pressure on the chain adjuster blade, so that the chain is in the normal running condition with no slack. When the hole nearly lines up it is helpful to turn the sprocket three teeth at a time to find the exact position. The peg on the sprocket retaining washer should push into place without any relative movement of the sprocket and plate. Before tightening the nut check that the engine has not moved from MC. Leave the tool in place on the head and tighten the nut to 50 Nm (37 foot pounds, 5 Kpm). Should the camshaft timing tool (8016) not be available, do not be tempted to tighten the nut against c amc pain tension; use a 16mm spanner on the camshaft flats (if no 16mm is available, a 5/8" AS. may serve).

When refitting the covers note the lengths of screws.
