REMOVAL AND INSTALLATION OF ENGINE BODY
Removal of engine
If work is to be done on the transmission unit only, the
entire power unit must be lifted out. The engine is then
separated from the transmission unit.
1. Disconnect the battery earth cable from the bat-
tery.
2. Jack up the car and place trestles in the front edges
of the sills.
3. Remove the hood. See Chapter 8.
4.
Drain off the coolant through the radiator draining
tap. Remove the expansion tank cap and open the
venting nipples on the heat exchanger and thermo-
stat housing.
5. Disconnect the coolant hoses, detaching the upper
hose from the engine and the lower one from the
radiator. The hose to the expansion vessel must be
detached from the latter.
6. Back off and remove the upper and lower radiator
retaining screws and remove the radiator.
7. Remove the air cleaner. Place a plastic cover No.
783729 over the carburetor air inlet to prevent the
entry of foreign matter into the engine.
8. Disconnect all hoses and cable connections from
the engine. Disconnect the battery cable from the
screws in the dividing surface between the engine
and the transmission unit.

Disconnect the engine side braces at the two re-
taining screws in the cylinder head.
10. Remove the throttle control by unfastening the sup-
port from the induction pipe and pulling out the
connection link to the throttle valve shaft.
11. Remove the two front engine cushions, working
from above.
12. Back off and remove the exhaust pipe flange nuts
at the cylinder heads. Separate the exhaust systems
at the joints behind the exhaust man ifold. Remove
the spacers at the cylinder heads and lower the front
exhaust system as far as possible.
13. Disconnect the freewheel control and the speedo-
meter cable from the gearbox.
Back off and remove the clutch cylinder retaining
screw and hang the cylinder up in a suitable posi-
tion.
14. Remove the floor mat and the wallboard panels.
Remove the gear lever knob and the rubber boot.
Remove the transmission casing (4 screws).

the rear engine bracket and the front gear shift
rod joint. Remove the center screw from the en-
gine bracket.
16. Remove the front taper pin of the gear shift rod
joint by moving the nut over to the opposite end
of the pin. The pin can then be removed by means
of the nut.
Open up the gear shift rod.
OPENING UP THE GEAR SHIFT ROD
17. Undo the large clamps round the rubber boots on
the inner universal joints.
To facilitate lifting and to avoid damaging the alter-
nator and cooling fan, these items should be removed.
18. Attach the lifting device, tool No. 786202, see Fig.,
to a suitable hoist and lift the engine carefully about
2 in. (50 mm). Pull the transmission pin out of the
rear engine bracket.
