• Use surface cleaner to degrease:
  • the end of the crankshaft (timing end),
  • the crankshaft timing sprocket bore and pressure faces at (24),
  • the contact surfaces of the crankshaft accessories pulley.

2 - Timing belt fitting procedure for engines fitted with a single unit camshaft timing sprocket

• Refit:

• 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):
