JLO Mower engine

Hi there,
I have an old mower to repair for a friend, it turned out to be a damaged piston, but the only references to the JLO engine, that I can
find in the internet are from Canada and the USA and then they were used in snow mobiles!
Does anyone know of a Company in UK that can supply replacement pistons and rings to a pattern or sample. This is all that is required as the rest of the engine is quite good and the cast iron bore has not been damaged. The alloy head is peppered with broken piston ring bits, but is still useable.
The engine concerned is aType L252L made in Germany - probably in the 60's or 70's and is a 247 cc two stroke, with the crank mounted vertically to drive a rotary cutter and having a separate drive to the tyres of two of the 4 rear wheels.
Any leads will be welcome. Thanks a lot George.

Hi George:
It is ILO not JLO, the stylised 'I' looks like a 'J'.
The company was absorbed by Rockwell - Tecumseh some years ago, and to my knowledge, nothing exists in the way of spares supply for these engines.
The last number I had for the UK side for Tecumseh was 01784 456301 Fax 460684.
I believe that the 252 refers to the capacityin cc, I have an L372 on a 4kVA generator.
Hope this helps.

Thanks Peter, I have done quite a lot of investigation myself, but decided that I shall have to have a piston made or I might be able to fabricate one from a blank. There must be quite a demand for replacement pistons, someone must be doing something. The engine plate says the type number i.e. L252L and it says that the Hubr. (German for swept volume??) is 247 cm3 so 252 is just a model, I would say. It is quite a high revving engine, I would say, so I can't replace it with a Briggs & Stratton, unless I change the pulleys too, - and the belts. What about rings, I seem to remember that these are available, but where?
Rockwell does not seem to be into engines - except for aeroplanes.
Thanks and regards George.

Rockwell owned Tecumseh, probably all gone now as 2-strokes are not good on emissions.
Look on ebay.com:

The L372 is 372cc, the L252 is, as you say, 247cc.
Bore is 66mm for your engine.

Sounds like you need a good old fashioned engine shop to help you find a suitable alternative piston. There's almost certainly one that will fit with a little modification
Where abouts are you based?

I suggest you buy a classic motorcycle magazine, there are various specialists that supply pistons for obscure old bikes, they may be able to help.

Lots of good advice - thank you all. I am in Norfolk and although the mower is not worth much, I do like to fix things. Most old stuff is more fixable than new, so I have a lot of old stuff.
My friend is now talking about spending 300 pounds on a new engine, but I wouldn't like to see him waste his money, something else is bound to go wrong! I was rather hoping that there was a register of pistons somewhere, so I could find something with the same dimensions , configuration and weight, I shall have another look at ebay, although my German is not up to much. I'll have a look at those links too, Peter.
Regards George.

George stelde dit ide voor :

http://www.jvmotors.nl/ says to have 6000 pistons in stock. Click on "Pistons", search the lists, where "Tweetakt" is "two stroke" and "Viertakt" is "four stroke".
