Started stripping the engine bay down.

Some interesting and quality repairs from the past involving tin foil, bathroom sealant and body filler.

Slow going but making sure it's done right.

Next up, engine came out.

Whoops.. timing cover is loose / has no gasket!

The gearbox on these is so compact!

This engine will either be for spares, or I might fix and sell it. So I decided to strip it down to see what I have.

Flywheel and RMS off.

Timing cover, sump and oil pickup off.

Mains and big ends out.

Crank and 3 pistons retrieved.

#4 does not want to come out!

https://wolfnomad.files.wordpress.co...583762323.jpeg

I've left it taking a bath in diesel / ATF on the underside. I will probably have to resort to fire, though.

On the plus side :

Bores look excellent.

Mains and big end shells look like they have done hardly any miles at all.

Pistons look great.

If I can get #4 out, it may be as simple as a quick hone, new piston rings, possibly new shells, gaskets, a quick going over the head, then I have a spare usable engine.

I still intend on using the twin carb spare engine I have for obvious reasons.

Minimum cost rebuild and keep would be my idea. 6” piece of 3x2 and a tap will reveal what you’ve got to work with. It won’t eat much mate!:teeth_smile:

This is a fascinating thread: good words and pictures plus an interesting storyline.

Unfortunately, no joy at all even with a sledgehammer.

Nothing to lose now. Next step is to light a barbecue in the cylinder.

Wow! It’s stuck then. Bugger!😯

Have you tried freezing it? :thinking:

Freeze the piston from the con-rod side and let it shrink the piston out - or at least that's what you hope for! :thumbs_up:

That's also a good idea.

I may as well start with the tools I have available, so I'll do a shallow 50:50 ATF and petrol mix with a rag wick, and light it.

Seems to be the go-to solution for a lot of people, so fingers crossed.

Please post a photo :-)

That may well work too, i'd go synthetic ATF if you have it, give it a goods shake with the petrol before letting it soak in and lighting it. :thumbs_up:



.......... or better still, a video! :thumbs_up: Not that i'm a pyromaniac or anything but there's something about watching "thermal therapy" on a stuck-in-bore piston! :thumbs_up:

Not too familiar with this !

So , get the bores hot, turn the block over and quench the piston to cool it?

Then over again and SMACK it?:teeth_smile:
