How To Remove BMW E30 Engine & Gearbox [M40B16] Motor & Transmission Removal Guide | 027
In this E30 build episode, I pass a huge milestone on the project, and I make the biggest move to date towards my M52B28 engine swap by pulling out the M40B16 motor.
Removing the engine from an E30 was easier than I'd anticipated, however it did take a whole day of relatively focused labour to complete. Here is the engine removal checklist I promised in the video:
1. Drain coolant (and oil if you like)
2. Remove coolant hoses between engine and radiator
3. Remove the radiator by undoing the top bracket and sliding it up and out
4. Remove the fan clutch - note the reverse thread
5. Remove the airbox and MAF etc
6. Remove horn
7. Remove radiator front duct
8. Remove alternator
9. Disconnect the power steering pump from the engine
10. Unhook fuel and brake booster lines
11. Disconnect heater matrix pipes
12. Remove wiring cover
13. Disconnect throttle cable
14. Remove intake manifold support bracket to gain access to electrics
15. Unplug all electrical connectors from the block
16. Disconnect starter motor electrics
17. Refit manifold bracket
18. Remove coil connection
19. Remove the earth strap
20. Remove exhaust manifold to downpipe nuts
21. Remove the clutch slave cylinder from the gearbox
22. Remove gearbox support bracket
23. Remove prop shaft bolts through the guibo - turn shaft with rear wheels lifted
24. Remove shift knob, gaiter and disconnect reverse switch
25. Unhook shifter linkage
26. Raise the rear end of the car
27. Strap up engine securely
28. Position engine crane and pick up tension
29. Manoeuvre engine and gearbox up and out of engine bay
From the above list of steps to remove and engine and gearbox, I think the biggest pitfall is removing the exhaust nuts between the manifold and downpipes. These are quite inaccessible and notorious for rounding off.
And here's what I used to help me do the job:
Folding Engine Crane: ebay.us/WlKh1M
Dewalt Big Impact Gun: ebay.us/l0Zzp8
Using a big impact gun and a 12" extension gives you a relatively straight shot on these when removing from an M40 motor. If these round off for you, your best bet will be to saw the exhaust off instead, as access is very tight.
If you can do this part, and you have access to an appropriate engine crane and straps, then the job is relatively easy.
I used a folding engine hoist and strong seat belts from one of our other projects, this worked a treat.
