Re-assembling

Sealing ring (timing gear side)

Fit tool [1b] on the tool [1a]

Fit the new ring seal (1) using tool [1a]

Remove the tool [1b]

WarningDuring the rebuilding operation, oil the lip of the tool, but do not lubricate the seal outer bearing surface

Fit the oil seal (1) in contact with the cylinder block; using tool [1a]

Sealing ring (flywheel side)

Fit tool [2b] on the tool [2a]

Fit the new ring seal (2) using tool [2a]

Remove the tool [2b]

WarningDuring the rebuilding operation, oil the lip of the tool, but do not lubricate the seal outer bearing surface

Fit the sealing ring (2) against the cylinder block; using tool [2a]

WarningClean the threads of the bolts (3)

WarningClean the contact surfaces between the crankshaft and the flywheel

Refit

  • The flywheel (3)
  • New bolts (4) (without tightening it)

Fit the tool [3]

Pre-tighten the bolts (4) to 2 ± 0,2 daNm; angular tighten to 23 ± 5°; using tool [4]

WarningRespect the tightening sequence indicated

Refit (according to equipment)

  • The clutch disc; centre the disc by means of tool [8]
  • The clutch mechanism; tightening to 2 ± 0,2 daN.m

Immobilise the camshafts by their flats (as "a")

Refit

  • Interior timing cover (10)
  • The inlet camshaft (9) dephaser pulley
  • The (8) bolt; pre-tighten to 3 ± 0,5 m.daN, then tighten to 8,5 ± 0,5 daNm
  • The inlet camshaft dephaser cap (7)
  • The exhaust camshaft pulley (6)
  • The (5) bolt; pre-tighten to 2 ± 0,2 m.daN, then tighten to 11 ± 1 daNm

Refit

  • The water pump seal (new seal)
  • The coolant pump

NoteCheck for the presence of the coolant pump positioning pins

WarningRespect the tightening sequence indicated

Tightening method for the screws

  • Pre-tightening to 0,8 daNm
  • Tighten to 1,4 ± 0,1 daN.m

Fit the crankshaft setting rod; using tool [5]

Pin the camshaft pulleys (6), (9); using the tools [6]

Refit

  • The crankshaft pulley (13)
  • The tensioning roller (12); pre-tightening to 1,5 ± 0,1 daN.m; tightening to 3,7 ± 0,4 daN.m
  • The roller tensioner (15) (without tightening it)

Install the timing belt (11) (observe the following order)

  • The crankshaft pulley (13) (hold the timing belt, using tool [7])
  • The tensioning roller (12)
  • The intake camshaft pulley (9)
  • The exhaust camshaft pulley (6)
  • The coolant pump (14)
  • The roller tensioner (15)

Remove tools [5], [6]and [7]

Turn the roller tensioner (15) in the direction of the arrow "b" using a hexagonal recessed spanner at "c"

Position the index "g" in position "e"; using a hexagonal banjo wrench (as "c")

WarningThe index "g" should pass the notch "f" by an angular value of at least 10°; if not, replace the tensioning roller or both timing belt and tensioning roller

Then bring the index "g" to its setting position "f", by rotating the tensioning roller in the direction of the arrow "d"

WarningThe index "g" must not go past the slot "f"; if it does, repeat the timing belt tensioning operation

Tighten the roller tensioner (15) bolt to 2,1 ± 0,2 daN.m

WarningThe hexagonal recessed spanner driving the roller tensioner should be below the joint face of the cylinder head (as "h"); if not, replace the tensioning roller or both timing belt and tensioning roller

Turn the crankshaft by 10 rotations clockwise

WarningNo pressure or external force should be applied to the timing belt

Check

WarningCheck the position of the index "g", it should be opposite the slot "f"; if the position of the index "g" is not correct, repeat the timing belt tensioning operations

Peg

  • The camshaft pulleys; using tool [6]
  • The crankshaft; using tool [5]

If the tool [5] can be fitted, continue the re-assembly operations

Remove the tools [5], [6]
