over the crankshaft, making sure to lift the
tappets clear of the cams.
Bolt the two halves of the crankcase
together.
If so desired the heated timing-side crank-
case can be supported on a block or blocks as
before and the crankshaft dropped into it.
Alternatively, the
supported in a vertical position as above and the
crankcase driven on to it (without heating) by
means of a tubular drift applied to the inner race
of the bearing or the crankcase may be drawn on
to the shaft by means of the sprocket nut with a
temporary distance piece in place of the
sprocket.

by two screwed aluminium plugs locked by
centre punching.
If the crankshaft is taken out of the engine
for any reason, the plugs should be removed and
the oil passage cleared of sludge.
8. Pump Worm Threads
If the threads in the crankshaft, into which the
pump worm screws, become damaged, a steel
wire insert can be fitted. The crankshaft should
preferably be returned to the Works for this to be
done or, alternatively, the hole can be drilled out
7/16 in. in dia., using the timing sprocket as a
drill bush and new threads tapped with a special
tool. Note that the thread is left-hand.
The method of fitting the wire insert is the
same as described in Section C, Subsection 14,
for the sparking plugs.
