- Place the crankshaft timing sprocket on a wooden
stand to avoid damaging its teeth.
- When extracting the crankshaft timing sprocket collet,
take care not to mark the crankshaft timing
sprocket bore.
- Pivot the collet towards the interior of the crankshaft
timing sprocket using a roll pin punch with a diameter
of 5 mm and a mallet.
- Slide a roll pin punch with a diameter of 3 mm into the crankshaft
timing sprocket groove (22).
- Position the roll pin punch with a diameter of 5 mm
at (23) on the collet.
- Pivot the collet to position it vertically.
- Extract the crankshaft timing sprocket collet using a
roll pin punch and a mallet.
- Use surface cleaner to degrease:

sprocket and cylinder head holes at (27), turning the
camshaft using a offset spanner (18 mm) if necessary.
- Check that the mark on the high pressure pump pinion (28) is opposite
the bolt head (29).
- Position the crankshaft so that it presses against the
TDC setting pin (Mot. 1489) (the crankshaft groove
(30) must face upwards).
- Fit the timing belt, starting with the crankshaft timing
sprocket, by aligning the marks on the timing belt
with those on the camshaft sprocket and the high
pressure pump pinion.
Note:
There should be 19 timing belt tooth spaces
between the marks on the camshaft sprocket and
the high pressure pump pinion.
3 - Timing belt fitting procedure for engines fitted
with a two-part camshaft timing sprocket
- Refit the timing tensioning roller.
- Put the tensioning roller lug (31) in the cylinder head groove (32).
- Engage the pin (3) (Mot. 1430) in the camshaft timing
sprocket and cylinder head holes, turning the
camshaft using a offset spanner (18 mm) if necessary.
- Check that the mark on the high pressure pump pinion (33) is opposite
the bolt head (34).
- Loosen the three camshaft timing sprocket crown
bolts (35) by one turn.
- Position the crankshaft so that it presses against the
TDC setting pin (Mot. 1489) (the crankshaft groove
(37) must face upwards).
- Fit the timing belt, starting with the crankshaft timing
sprocket, by aligning the marks on the timing belt
with those on the camshaft sprocket and the high
pressure pump pinion.
Note:
There should be 19 timing belt tooth spaces
between the marks on the camshaft sprocket and
the high pressure pump pinion.
- Use a torque wrench to torque tighten the camshaft timing sprocket crown
bolts (14 N.m) (38).
4 - Second part of the timing procedure for engines
fitted with a single unit or two-part camshaft timing
sprocket
- Position the tensioning roller adjustable index marker
(39) opposite the lug, turning the eccentric cam
anti-clockwise using a 6 mm Allen key.
- Use a torque wrench to torque tighten the tensioning
roller bolt (27 N.m).
- Refit the accessories crankshaft pulley with a new
bolt.
- Torque and angle tighten using a torque/angle
wrench or a torque wrench and a cylinder head
bolt tightening gauge (angular measuring type)
(crankshaft against the TDC setting pin):
- the crankshaft accessories pulley M12 bolt (60
N.m + 100
