1 This is a direct reversal of removal and separation from the transmission. Take care not to damage the radiator or front wings during installation.

Reconnection
2 Reconnection of the engine and transmission is a reversal of separation, but if the clutch has been dismantled, check that the friction plate has been centralised as described in Chapter 6.

Installation
OHV engines
3 First check that the engine sump drain plug is tight and then, where applicable refit the selector shaft cap nut (removed to drain the transmission oil) together with its spring and interlock pin. Apply sealer to the cap nut threads when refitting (see Specifications Chapter 7, Part A).

4 Manoeuvre the engine/transmission under the vehicle and attach the lifting hoist. Raise the engine/transmission carefully until the right-hand rear mounting can be engaged.

Refit the mounting nut and bolt loosely only at this stage.

5 On pre-1986 models refit the front mounting and anti-roll bar support plates, then refit the left-hand front and rear mountings loosely only.

6 On 1986 models onwards refit the transmission support crossmember.

7 Lower the hoist and let the power unit rest on its mountings. Ensure that none of the mountings are under strain, then tighten all the mounting nuts and bolts and remove the hoist.

8 The driveshafts and suspension arms should now be refitted using the procedure described in the manual transmission refitting procedure in Chapter 7, Part A.

9 Reconnect and adjust the gearchange linkage using the procedure described in Chapter 7, Part A.

10 Fit the starter motor leads to their terminals.

11 Connect the engine earth leads.

12 Refit the exhaust system and bolt the downpipe to the manifold. Refit the hot air box which connects with the air cleaner.

13 Reconnect the clutch operating cable.

14 Reconnect the electrical leads, the fuel pipe, the brake vacuum hose and the speedometer cable.

15 Reconnect the throttle cable and the choke cable (where applicable) as described in Chapter 4, Part A.

16 Reconnect the radiator coolant hoses, and heater hoses.

17 Fill up with engine oil, transmission oil and coolant, then reconnect the battery (photo).

18 Refit the bonnet, bolting the hinges to their originally marked positions. Reconnect the screen washer pipe.

19 Fit the air cleaner and reconnect the hoses and the air cleaner inlet spout.

20 Once the engine is running, check the dwell angle, timing, idle speed and mixture adjustment as applicable (refer to Chapter 1).

21 If a number of new internal components have been installed, run the vehicle at restricted speed for the first few hundred miles to allow time for the new components to bed in. It is also recommended that with a new or rebuilt engine, the engine oil and filter are changed at the end of the running-in period.

22 Refitting is a reversal of the removal procedure described in Section 11.
