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 tension wheel.
- Put the tensioning roller lug (15) in the cylinder head groove (16).
- Engage the pin (3) (Mot. 1430) in the camshaft timing
sprocket and cylinder head holes, turning the
camshaft using an 18 mm offset spanner if necessary.
- Check that the mark on the high pressure pump (17) is opposite the bolt
head (18).
- Screw the old crankshaft accessories pulley bolt fitted
with a spacer (20) (which does not cover the timing
sprocket mark) into the crankshaft.
- Position the crankshaft so that it presses against the
TDC setting pin (4) (Mot. 1489) (the crankshaft
sprocket collet (19) must face upwards).
- Remove one bolt from the camshaft timing sprocket
crown.
- 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 belt tooth grooves between
the marks on the camshaft sprocket and the high
pressure pump pinion, and 51 belt tooth grooves
between the crankshaft sprocket and the high
pressure pump pinion.
- 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 Nm)
using a torque wrench.
- Check that the camshaft timing sprocket crown bolts
are not fully locked against the camshaft timing
sprocket crown. If they are, repeat the timing belt refitting
procedure.
- Refit the bolt from the camshaft timing sprocket
crown.
- Torque tighten the camshaft timing sprocket
crown bolts (14 Nm) using a torque wrench.
- Remove:
- the TDC setting pin (Mot. 1489),
- the camshaft timing sprocket setting pin (5) (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 (6)
(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 a offset
spanner (18 mm) to set 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 high pressure pump pinion mark (26) is opposite the bolt
head (27),
- that the crankshaft timing sprocket collet (28) is positioned
vertically at the top,
- that there are 19 belt tooth grooves between the marks on the
camshaft sprocket (29) and the high pressure pump pinion (30),
- that there are 51 belt tooth grooves between the crankshaft sprocket
marks (31) and the high pressure pump pinion (30).
Note:
After two turns, the tensioning roller index markers
may be in two different positions.
The rotation of the tensioning roller 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 (32) in the middle
of the timing window (33), turning the key anticlockwise.
- Torque tighten:
- the tensioning roller bolt (27 Nm) using a torque
wrench.
- the camshaft timing sprocket crown bolts (14
Nm) using a torque wrench.
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 (34) in the middle
of the timing window (35), turning the key clockwise.
- Torque tighten:
- the tensioning roller bolt (27 Nm) using a torque
wrench,
- the camshaft timing sprocket crown bolts (14
Nm) using a torque wrench.
- 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 (7)
(Mot. 1430).
- If the pin does not engage, repeat the timing belt refitting
operation.
- Refit the accessories crankshaft pulley with a new
bolt.
- Tighten to torque and angle (crankshaft in contact
with the TDC setting pin) the crankshaft accessories
pulley bolt M14 (120 Nm + 95
