II - REFITTING OPERATION
1 - Adjusting the timing
a
aSet the camshaft grooves horizontally and below the
centre line by turning the camshafts with the (Mot.
1496) if necessary.
aFit the (Mot. 1496) with the (Mot. 1750).aFit:
-the (Mot. 1496) fitted with the (Mot. 1750) on the
end of the camshaft,
-a lifting eye bolt to secure the (Mot. 1496).
aIf fitting a new camshaft dephaser, check the
dephaser locking mechanism (see 11A, Top and
front of engine, Camshaft dephaser: Removal -
Refitting, page 11A-135) .
aRefit the camshaft dephaser (see 11A, Top and
front of engine, Camshaft dephaser: Removal -
Refitting, page 11A-135) . Note:
If the stud loosens with the nut (see 11A, Top
and front of engine, Camshaft: Removal -
Refitting, page 11A-82) (Technical Note 3887A,
11A, Top and front of engine).
WARNING
Always degrease:
-the end of the crankshaft (timing end),
-the timing sprocket bore and bear ing faces,
-the crankshaft accessories pulley bearing
faces,
-the camshaft ends (timing end),
-the camshaft sprocket bores and bear ing faces.
This is to avoid timing slippage.
This slippage leads to engine damage.
