ENGINE
factured special retainers for this pur-
pose (Fig. 22) and it is suggested that
these are employed. Until this is done
the piston assemblies must not be
moved, for any movement will be
transferred to the sleeve and damage
the figure of eight washers. If damage
is undetected, water leakage will result.
An alternate method is to insert the
cylinder sleeves alone into the block,
clamp them with the Churchill sleeve
retainers to ensure no further move-
ment and then fit the piston assemblies
similarly as described in paras.
(X)
and
( x i ) .
(xiv) Having the sleeve retainers in position,
the connecting rods may be fitted to
the crankshaft, Nos. 1 and 4 cylinders,
followed by 2 and 3 cylinders. The
caps are fitted to their respective rods
and in such a manner that the tubular
dowel will sink into its recess and their
identification numbers coincide.
It
should be noted that the bearing cap,
because of this dowel, can only be
fitted one way round. The cap is
secured by two bolts and a locking
plate. Tighten the bolts to the correct
torque loading and turn over the tabs
of the locking plates.
(xv) Push the oilite bush into the centre of
the crankshaft at its rear end and tap
the flywheel locating dowel into posi-
tion in the flange.
(xvi) Fit flywheel located b$ the dowel so
.that the arrow marked on its periphery
lines up with the centre of the cylinder
:block with Nos. 1 and 4 pistons at
'T.D.C. Secure flywheel with the four
setscrews and two locking plates, then
turn over the tabs of the locking plates
when the setscrews have been tightened
to their correct torque loading.
(xvii) Utilising jointing compound affix the
front plate packing and locating the
engine plate on the two dowels secure
with the five bolts and locking washers.
Fit the engine mountings secured by
two nyloc nuts.
(xviii) T o the forward end of the crankshaft
fit
the sprocket locating shims, the
W o o d d e key and
the
sprocket wheel.
(xix) Lubricate the camshaft and feed into
the cylinder block and secure the front
bearing with two setscrews. Check the
end float as described on page 17.
Rest the camshaft chainwheel on the
camshaft spigot and turn the chain-
wheel about the camshaft until the
identification punch mark on the end
of the camshaft can be seen through
the punch marked hole in the chain:
wheel. Secure the chainwheel to the
camshaft leaving the two setscrews
finger tight. If a replacement chain-
wheel is being fitted, see "12. To set
Valve Timing in the Absence of Mark-
ings" (page 22). Check the alignment
of the chainwheel with that of the
sprocket on the crankshaft, taking into
consideration the end float of the cam-
shaft. The alignment can be adjusted
by altering the thickness of the shim
between the crankshaft sprocket and
the abutment on the crankshaft.
(xx) Turn the camshaft chainwheel until
the scribe line thereon lines up with
the scribe line on the crankshaft
sprocket. Without moving the cam-
shaft remove the chainwheel and when
removed fit the timing chain to this
wheel and the one on the crankshaft.
Reposition the camshaft chainwheel
and check by simulating pressure of
the chain tensioner that the timing
marks have retained their positions
and re-adjust if necessary. Tighten
bolts to correct torque loading and
turn over tabs of locking plates. Lubri-
cate tappets and place in tappet
chambers.
( x x i ) Fit the chain tensioner to its pin and
secure with washer and split pin.
Screw in timing cover support bolt to
the engine plate and fit the oil de-
flector to the crankshaft so that the
raised edge faces the timing cover.
(xxii) Press the oil seal with its lip inwards
into the timing cover and
fit
this cover
with its packing to the engine plate
utilising one nut, eleven bolts with
four nuts.
NOTE-See that the short earth bond-

is attached under the head of the bolt
