The Series Land Rover engine is unlike many others, in that it cannot be removed (from a standard Land Rover Series 1,2 or 3 chassis) with the gearbox still attached. This is because two cross members of the chassis pass beneath the gearbox/engine unit.
If removing the Series engine, the following items should be removed first, for either convenience and/or safety: bonnet, battery. Also, if the engine is to be completely dismantled, then the engine oil should be drained out.
The next items should be removed to gain necessary access to the engine and transmission: radiator grill panel, front floor and gearbox tunnel.
The Series Land Rover engine can be removed without ALL the ancillary fittings being removed, but the following is a list of those items which must be removed: air cleaner, radiator, exhaust pipe flange.
Next, it is necessary, for both the diesel and petrol engine,
to have all fuel, water and electrical connections disconnected from it. Loose ends should be protected and tied safely out of the way.
Now the engine can be supported on a hoist, using slings or chains and the engine mounting bolts should then be undone. The engine is then lifted sufficiently to remove the mountings completely and then lowered to its original position. Next, remove all nuts and bolts fixing the clutch and engine housings together and move the clutch slave cylinder to one side. Place a 2-3cm block of wood between the gearbox flange and the chassis cross-member and lower the gearbox onto it. Pull the engine forward until the gearbox input shaft is clear of the clutch housing and then lift the engine carefully from the Land Rover.
Re-fitting the engine into your Series Land Rover is basically the reverse of the above. Care should be taken though to ensure that the gearbox input shaft enters the clutch assembly perfectly horizontally. If the shaft does not quite fully enter then turning the crankshaft starter dog slightly can help match up the splines on the shaft as is necessary.
