remove petrol engine from Enfield frame

[Sphere]

Can you just remove the petrol engine from a 90's Enfield frame, or will the bike collapse on itself when you do?

I need to make a mockup for the subframe so I can have something welded. Usually I resort to http://www.enfielder.com/ but apparently that site is down and has been for some time now.

You are safe to remove the engine, just don't let any silly bugger sit on it while the engines out, you'll bend the frame.

Yes some people will try and do it.

Thanks Andrew. Now, to swap some of our Dutch rain for your Aussie sun.

So here's a pic of the block that needs to come out. I have encircled 3 bolts that I have heard need to be removed. Below is also a set of instructions I found on the web. Step XIII through XV are unclear to me.

- What are the front engine plates?
- What is the stud securing the rear engine plate to the frame?
- Which way do you slide the engine?

Also, do you remove the 3 bolts I encircled entirely? With a screwdriver and hammer or something? I'm worried that I'm going to damage something

I have removed a respectable amount of bolts, the centre stand and the exhaust. The block isn't out yet, because I can't persuade the final drive chain to come off. I'll see about making a tool.

Ok here goes:



All the white ones need to be removed, but get the bike on a decent paddock stand and strap it down, I'm serious; it will fall over when you start pulling out the motor.

You can get away with less, it will be obvious why after the first time you do it as the gearbox just rests on the support stud and can be lifted off but the smaller stud goes through the bottom of the engine so needs to come out.

I would suggest you get a mate to help if possible.

The main swingarm nut I've marked with yellow should really be replaced with the proper large nut, about 50mm across as this spreads the load to the plate better.

Cheers Dave. I had to call it quits because of ominous skies. And low and behold it's pouring.

Hopefully I can get it done tomorrow:

About the paddock stand: I have noticed that the bike is pretty unstable right now. To unscrew some of the badly corroded nuts I put the bike on its side. Good thing I have a big washing machine tub under it, because the block started spilling oil. Unfortunately I will have to go about it differently. Perhaps prematurely removing the front wheel has something to do with it

I'm sure glad that I don't have to put it back in, because it was a pain in the you know where to remove it. Solo. Without a front wheel. No straps. What surprises me is the number of nuts in annoying spots.

Thanks a lot for the pointers.

It was a beautiful sunny day today A perfect opportunity to take a walk with the family... wait!
Scratch that, there's a frame I need to strip

I'm genuinely surprised by the amount of metric nuts I encountered. A lot of 13, 15, 18 and 24. Unfortunately I killed/nicked/dented/tore 2 bearing races. Seems they were as sturdy as tin cans
