To remove the timing chain and pinion assembly:
4
Undo the nuts. Wedge the pinions by means of the setting gauge 1680-T
( see Pl. 15, fig. 2) or fix the crankshaft
by means of a wooden wedge inserted between a crankshaft throw and the crankcase; (spanner 1731-T, see
P1.15, fig.3) for the camshaft nut and spanner 1667-T
( see PI. 15, fig. 1) for the crankshaft nut . . . . . . . . . . . . . . . .
b)
Turn the crankshaft until the throws are horizontal.

IMPORTANT - It is essential to place the crankshaft in this position before removing the timing chain and pinion
assembly. Since the camshaft is not under control, if one of the valves is lifted and the crankshaft rotated, the
corresponding piston cannot pass the T.D.C. without fouling the valve.
4
Remove the timing'chain and pinion assembly without displacing them. Place chain and pinions on the bench held
in position by the setting gauge 1680-T (see P1.15, fig.2).
Remove the keys, and thrust washer (5), the adjusting shims (7) and the bearing thrust ring (6) (see Pl. 1) . . . . . . .

To Fit
%
From the shim steel 0.18'
mm thick cut out a strip 200 mm long x 10 mm wide.
To fit the oil seals (see Pl. 14):
I
a) Fit the upper shell (9) on the cylinder block and the lower shell (10) on the bearing cap. Insert the fixing screws
(40) without tightening them.
b)
Make sure that the upper bearings (in the crankcase) are clean. Oil the parts with an oilcan.
Place the shim steel strip (prepared in paragraph 21) round the crankshaft oil-thrower (see Pl. 14, fig. 1) and
mount the crankshaft in its bearings.
With the lower bearing in position in the front bearing cap, fit the bearing cap.
Guide the cheek (11) (see Pl. 1) during this operation.
Tighten the assembly screws (8) of the cap sections.
Tighten the bearing cap fixing screws to 72 ft.lbs
(10 m.kg) (torsion spanner 2471-T, see P1.7, fig.2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
