REFITTING
I - REFITTING PREPARATION OPERATION
aAlways replace:
-the nut from the camshaft pulley,
-the camshaft seal.
a
aUsing ABRASIVE PADS clean the load-bearing sur-
faces of the camshaft bearings.
aDegrease the load-bearing surfaces of the camshaft
bearings using SURFACE CLEANER (see Vehi-
cle: Parts and consumables for the repair) (04B,
Consumables - Products) and a CLEAN CLOTH.
aApply four beads (1) of RESIN ADHESIVE (see Ve-
hicle: Parts and consumables for the repair)
(04B, Consumables - Products) 7 mm in diameter
on the cylinder head.II - REFITTING OPERATION FOR PART
CONCERNED
aPosition the camshaft by positioning the timing end
camshaft groove vertically.
aRefit the camshaft bearings in accordance with their
original positions (bearing No. 1 engine flywheel
end).
aRefit in order bolts (1) , (3) , (4) and (2) of the cam-
shaft bearings.
aTighten the camshaft bearing bolts (1) , (3) , (4) and
(2) in order.
aRefit the camshaft bearing bolts in order.
aTighten to torque and in order the bolts of the cam-
shaft bearings (10 N.m).
III - FINAL OPERATION
aRefit:
-the camshaft seal (see 11A, Top and front of en-
gine, Camshaft seal, timing end: Removal - Re-
fitting, page 11A-138) ,
-the vacuum pump (see Vacuum pump: Removal
- Refitting) (37A, Mechanical component controls),
-the rocker cover (see 11A, Top and front of en-
gine, Rocker cover: Removal - Refitting, page
11A-66) ,
-the timing belt (see 11A, Top and front of engine,
Timing belt: Removal - Refitting, page 11A-27) ,
-the camshaft position sensor (see 13B, Diesel in-
jection, Camshaft position sensor: Removal -
Refitting, page 13B-14) ,
-the crankshaft accessories pulley (see 11A, Top
and front of engine, Crankshaft accessories
pulley: Removal - Refitting, page 11A-20) , WARNING
The joint faces must be clean, dr y and free from
grease (avoid finger marks).
WARNING
Applying excess sealant could cause it to be
squeezed out when parts are tightened. A mix-
ture of sealant and fluid could damage certain
components (engine, radiator, etc.).
