Looking for Listeroid 6/1 breakdown and rebuild manual
« on: January 05, 2026, 04:28:52 PM »
Hi ALL,

I used to have a PDF on breaking down a Listeroid 6/1. Following the instructions, I found about a cup of sand in the water jacket and maybe a teaspoon in the oil pan.  However, my laptop crashed and I lost the pdf.  I was wondering if someone could send another copy, or a link to me?

Thanks in advance.
Matt

I sent an email off to George for a CD.  Hopefully he responds.

I'm not sure how much George is doing these days, his site was inactive for a long time but I see he has recently posted a few things on it.
What exactly are you looking for? He never had to my knowledge,  a step by step, bolt by bolt tear down and rebuild instructions. After running approximately 40 of them through my shop over the years I can tell you without reservation a few things. There is no such thing as one that is put together correctly. No such thing as one free of sand and slag and you cannot tell much via a peak through the inspection door and a swipe of the sump bottom with a rag. There is sand and slag you cannot see unless you know exactly where to look and absolutely cannot remove unless the engine is taken all the way down to a bare crankcase  the order of which is well within the skill set of anyone who should be doing it and without any manual to lead him through it. There are hiwever a few important clearances and procedures that I can provide should you choose to go about correcting your engine but I'm going to save my two typing fingers until you decide to go that route. You also have the option of just running it and taking your chances bit it's a fools bet that it will be OK.

Thank you 38ac. 

I mainly remember the pdf showing the list of places to check for sand, and other "Gotchas" to look out for. 
I haven't heard from George, so he may have retired his keyboard.  I will post questions as I run into them.

P.M. me. I do have some old files that might be helpful.
I found out to my dismay, and after several years of service, that I missed a large bit of casting sand on the underside of the piston. Cost me a new crankshaft, etc.
Cheers

Over the years Id guess the average sand and slag removal would fill a soup can. Worst one was a twin that had enough in it to fill a coffee can. Least I ever removed was 20 times what would be needed to wear out the engine in short order. The very early and very late ones were the worst. There was a time in the middle of importation when lots were coming in that while not clean they had much less sand in them and we're reasonably assembled.  Every nook and cranny will have sand, the harder the area is to see and get at the more likely you will find sand there. The underside of the crankcase deck, where the cylinder sets is always bad. The shelf behind the camshaft is another.  Every corner, the base of every rib. It's actually impossible to get it all out because of the poor casting qualities. That's why I always preached to hot tank the block to get rid of all the paint and oil, you can then see the sandy places clearly AND what you cannot remove can be sealed in with Gyptol primer.
A few people have done things halfway and got away with it but it's a suckers bet that you will get away with it.
