22 Engine/transmission -

reconnection

1

1 Support the weight of the transmission and
offer it squarely to the engine. The splined
input shaft should pass easily through the hub
of the driven plate, provided the plate has
been centralised as described in Chapter 5. It
may be necessary to align the splines with the
hub grooves, in which case have an assistant
turn the crankshaft pulley nut. The alignment
dowels will make the connection stiff, so
drawing the engine and transmission together
with two connecting bolts will ease it.
2 Once the engine and transmission are fully
engaged, insert and tighten all the connecting
bolts. Locate the lifting eyes.
3 Bolt on the flywheel housing cover plate
and the mounting brackets.
4 Bolt on the starter motor.
