How to remove the engine


I now need to get my head around the complexities of removing the engine and taking it somewhere for a possible re-bore, new pistons, rings and valves. Having now removed the dog box I will need to remove the engine, not a trivial task. I have researched the steps to remove the engine which are as follows:

Steps to remove the engine
1. Remove the floor center plate.

2. Disconnect and remove the selector control cable from the transmission.

3.  Disconnect the outer lever from the transmission shift shaft.

4. Disconnect the gasoline line at the fuel pump.

5. Disconnect the oil pressure gauge line.

6. Disconnect the throttle control rods.

7. Disconnect the wiring at the generator.

8. Disconnect the wiring at the starter etc.

9. Disconnect the windshield wiper tube at the manifolds.

10. Disconnect the heat indicator at the head.

11. Disconnect the engine ground strap.

12. Disconnect the clutch control bracket at the flywheel housing.
13. Disconnect the clutch throw-out fork.

14.  Disconnect the speedometer cable from the transmission 

15. Disconnect the front end support (2 bolts).


16. Disconnect the exhaust pipe at the manifold.

17. Disconnect the rear universal joint and propeller shaft.




18. Attach a chain hoist to the engine and remove the bolts from the rear engine mountings.

19. Lift the engine free of the rear engine support cross member.


20. Remove the engine from the frame pulling forward.

Reverse the above operations when re-installing the engine. Pay special attention to:
·         Clutch pedal lash
·         Safety shift adjustments
·         Install two new exhaust pipe gaskets
·         Adjustment of throttle range
