Listeroid Engines / Re: Top quality Listeroid exporter
« on: April 09, 2022, 09:19:31 PM »
It's difficult to believe that nowadays something can still be so badly made, and unfit for purpose.

Looking at videos on YouTube, there looks to be thousands of Listeroids running daily in India, many look like they've been sat there for many years, happily running with no maintenance at all.

I sometimes wonder if the "bad ones", the "Friday afternoon" jobs get earmarked for export, knowing that they're not going to get sent back under warranty.
I know Listers used to do exactly the same with a faulty D type, it would usually end up being sent to Australia, knowing that it would never return.

Thanks for all your suggestions so far.
I had a small but useful victory last night.....
Tried unscrewing the end cap, and holding the handwheel still at the same time, essentially using the fine thread as a jack to pull on the valve stem. After going tight, another nudge with a long spanner had something give, and it continued to turn out.
So I now have the handwheel, valve stem and the first half of the chamber out, with no damage.
I'm going to leave the inner chamber soaking before trying the compression method again, and if that doesn't shift it, then I'll decarbonise where I can and leave it alone.

Thanks again.

38ac,
No, just to clarify, the threaded piece has unscrewed, ( the part with the large fine thread into the head, with the square head on, together with the handwheel, ) but it will only back out as far as the end of the threads, I can pull it maybe 1/2" more against a spring, but that's it .
So I'm guessing that both halves of the combustion chamber are jammed in, with the valve stem head between them .
Looking at the parts book, the 3-1 COV is slightly different to the
5-1/6-1, so I'm not even sure that an Indian replacement COV would fit, hence I need to make sure I don't damage the original.

I've used an ultrasonic cleaner before with siezed carburettor jets in corroded zinc casting carbs, and the vibrations and hot liquid have proved successful. The thing is finding someone with a cleaning bath big enough for a CS head, most are just big enough for a lawnmower carb.
Certainly another avenue to explore though, thanks Mihit.

Thank you for the suggestions so far, I'm hoping it won't be that badly stuck, as the rest of the engine is oily and has come apart really easy.
I'm going to give it a good long soak, (a few weeks) whilst I'm doing other things and go from there.

I've seen someone push a seized piston out with the grease gun method, but as you say, be very careful.
If it comes to that I'll probably use thick oil in the gun, for ease of washing out after and put a pressure guage in the line, wouldn't go more than about 800-1000 psi. (I think compression on high setting is about 600)
Thanks again and any more ideas are very welcome.

Hi,
New on here, although been lurking here as a guest for a while and been collecting engines for 25 years.
Just aquired a lovely original CS 3-1 from a farm in Norfolk, it will fire up, but I'm going to strip it right down as the insides are absolutely blocked solid with sludge and bits of debris, I'm just not happy I can get it cleaned out properly without stripping it.
Anyway, all coming apart easily, flywheels etc off but can't get the changeover valve out .
The outer plug cap came unscrewed easily, but the inner parts are jammed solid with carbon etc. I've tried the "compression" method several times, and I'm not brave enough to actually start the engine to try to blow it out. My plan maybe to let it soak a couple of weeks in something that softens carbon (diesel or redex maybe) and if that doesn't loosen it may try to rig up a steel plate over the combustion chamber with a 1/8 grease nipple and use a grease gun to hydraulically push the chambers out.
Can't get in with any heat without risking damaging the valve stem or spring.

Hate the thought of destroying something that's lasted 70 years and replacing it with some Indian rubbish parts.

Anyone any ideas for getting it out?
