Adjusting the timing

WARNING: it is essential to degrease the end of the crankshaft (timing side), the bore and the bearing faces of the timing pinion, the bearing faces of the accessories pulley and the ends of the camshafts (timing side), the bores and the bearing faces of the exhaust camshaft pulley and the inlet camshaft dephaser; to prevent there being any slip between the timing, the crankshaft, the exhaust camshaft pulleys and the inlet dephaser, which may damage the engine.

NOTE:

to make it easier to position the grooves horizontally, position the pulley and dephaser, then tighten the old nut of the pulley and the old bolt of the

dephaser to a torque of 1.5 daN.m MAXIMUM. Check that the pistons are positioned at mid-stroke (to prevent any contact between the valves and the pistons).

Position the grooves of the camshafts horizontally as shown in the diagram below (rotating the camshafts using tool Mot. 799-01 if necessary).

15201R

– the lower timing cover without tightening the bolts, – the crankshaft accessories pulley, pre-tightening the bolt (without locking the bolt, clearance of 2 - 3 mm

between the bolt and the pulley).

NOTE:

– the crankshaft accessories pulley bolt can be reused if the length under its head does not exceed 49.1 mm

(otherwise replace it),

– do not oil the new bolt. However, when reusing the bolt, it must be oiled on the threads and under the head.

pulley using tool du Mot. 799-01.

NOTE: check that the nut and the bolt of the camshaft

pulleys do not touch their respective pulleys. To do this, from time to time, push the camshaft pulleys

against the camshafts.

Alight the references (6) and (7) if necessary, slackening the nut of the tensioning roller by a maximum of one turn whilst holding it with a 6 mm Allen key. Then tighten the nut finally to a torque of
