• Slacken the timing tension wheel by turning the eccentric cam using a 6 mm Allen key.
• Remove:
  • the timing belt,
  • the timing tensioning roller.

REFITTING

I - REFITTING OPERATION FOR PART CONCERNED

• Check:
  • that there is no oil leak from the camshaft and crankshaft seals,
  • the condition of the coolant pump (hard seal, play in the shaft, fluid leak, shaft rotation, (see Technical Note 3175A, Cooling system fault finding, 19A, Cooling, Cooling system - Fault finding chart ALP 8).

• Refit the timing tensioning roller.
• Put the tensioning roller lug (14) in the cylinder head groove (15).
• Engage the pin (16) (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 high pressure pump mark (18) has shifted one tooth to the right of the vertical axle (17).

• Tighten the old crankshaft accessories pulley bolt fitted with a spacer (which does not cover the timing sprocket mark) (19) onto the crankshaft.

• Position the crankshaft so that it presses on the TDC setting pin (Mot. 1489) (the crankshaft timing sprocket collet (20) must face upwards).

• Remove one of the camshaft timing sprocket crown bolts to prevent full lock during the following actions.
• Loosen the other two camshaft timing sprocket crown bolts (21) by one turn.

• Fit the timing belt, starting with the crankshaft sprocket, by aligning the marks on the belt with those on the crankshaft and camshaft sprockets, and the high pressure pump pinion.

Note: There should be 19 tooth valleys on the belt between the camshaft sprocket marks and the high-pressure pump, and 51 tooth valleys between the crankshaft sprockets and the high-pressure pump.

• Position the tensioning roller adjustable index marker (22) opposite the lug (23), turning the eccentric cam anti-clockwise using a 6 mm Allen key.
• Torque tighten the tensioning roller bolt (27 N.m).

• Position the tensioning roller adjustable index marker (22) opposite the lug (23), turning the eccentric cam anti-clockwise using a 6 mm Allen key.
• Torque tighten the tensioning roller bolt (27 N.m).

• Refit the bolt from the camshaft timing sprocket crown.
• Torque tighten the camshaft timing sprocket crown bolts (14 N.m).
• Remove:
  • the TDC setting pin (Mot. 1489),
  • the camshaft timing sprocket setting pin (Mot.1430).

• Rotate the crankshaft clockwise through two revolutions (timing end). Before the hole (24) in the camshaft timing sprocket is opposite the hole (25) in the cylinder head:
  • screw the TDC setting pin (Mot. 1489) into the cylinder block,
  • bring the crankshaft slowly and smoothly against the TDC setting pin.

• Lock the camshaft timing sprocket using the (Mot.1430).

• If the pin (Mot. 1430) does not engage:
  • loosen the camshaft timing sprocket crown bolts by a maximum of one turn,
  • turn the camshaft timing sprocket hub using an 18 mm offset spanner to facilitate setting of the camshaft timing sprocket hub,
  • do not retighten the camshaft timing sprocket crown bolts.
• Loosen the camshaft timing sprocket crown bolts by a maximum of one turn.

• Check that the crankshaft timing sprocket collet (26) is positioned vertically at the top.

Note: After two turns, the tension wheel index markers may be in two different positions.

The rotation of the tension wheel eccentric depends on the position.

First position

• Loosen the tensioning roller bolt by no more than one turn, holding it with a 6 mm Allen key.
• Gradually align the adjustable index (27) in the middle of the timing window (28), turning the key anticlockwise.
• Torque tighten:
  • the tensioning roller bolt (27 N.m),
  • the camshaft timing sprocket crown bolts (14 N.m).

Second position

• Loosen the tensioning roller bolt by no more than one turn, holding it with a 6 mm Allen key.
• Gradually align the adjustable index (29) in the middle of the timing window (30), turning the key clockwise.
• Torque tighten:
  • the tensioning roller bolt (27 N.m),
  • the camshaft timing sprocket crown bolts (14 N.m).
• Remove the following tools:
  • the TDC setting pin (Mot. 1489),
  • the camshaft timing sprocket setting pin (Mot.1430).
• Rotate the crankshaft clockwise through two revolutions (timing end). Before the hole in the camshaft timing sprocket is opposite the hole in the cylinder head:
  • screw the TDC setting pin (Mot. 1489) into the cylinder block,
  • bring the crankshaft slowly and smoothly against the TDC setting pin.

• Lock the camshaft timing sprocket using the (Mot.1430).
• If the pin does not engage, repeat the timing belt refitting operation.

• Refit the accessories crankshaft pulley with a new bolt.
