That is a puzzle how they escaped, better call Scooby Doo and the Mystery Machine. How does the ring groove look? Is it rounded out? If not I would say the PO put it together like that with a short ring. I've seen some doozys in my time. And no one will cop to them. Good luck Keith.

The ring groove looks good so far. I'll get a closer look when I clean up the pistons...

I wondered if someone might have put in a broken ring. If that's all they had, I guess I could see doing that. But then it broke some more, and that could have done bad things. So maybe not such a good idea after all!

Piston Ring End Gaps- the numbers are in. I tried to take a photo of my notebook, hopefully the figures are legible. If not, I'll edit and type them all in. Spec is 0.007" - 0.017". The next mystery is how on earth was the compression so good before I pulled this apart?? These rings are *really* worn!!

I also took a closer look at the number four piston, and the ring lands look great, nice and sharp! So I don't think any of the wayward parts escaped that way...

Are those numbers with the rings in the top 1/2" of their respective bore, made even with a piston, then feeler gauge the gap? If so they are very worn. I would measure again. Just to make sure, they do seem even though. I'm sure you are using page 9.8 / 10.1 in the manual to help. As for the high compression readings , did you remove a lot of stuff from the chamber head and piston?

Yeah, that looks like the manual I have. I had them down about 3/4" from the top. An aerosol can is also 2-5/8", so that's what I used to make sure they were nice and square. I wiped the rings and the cylinders nice and clean first. Had to use three sizes of feeler gauge together to get to some of those large numbers!

Oh, forgot- I haven't cleaned up the head yet. But it really doesn't look to very carboned up. I also believe that it isn't original to the engine as the little bit of paint remaining on it is gold. Were the later engines higher compression? It ocurred to me that it may have been milled already. I'll have to get some plexiglass and see.

No work on the Plant today, but since it has been determined that nothing is catastrophically wrong with it, I ordered a big bunch of parts today. Gaskets and seals, two rod bearings, and a new ball bearing for the generator.

I did not order any exhaust gaskets as I do not yet know if I will find a marine manifold. A fellow Stakker offered one and sent photos, but then we lost touch. I'll have to get in touch with him again.

Have not yet found anything available for the Wico XH-2006 magneto, but it was working fine after I replaced the condenser.

Curiously the 1974 parts manual shows no parts for the Wico, saying it was superceded by a Fairbanks Morse in 1959 (per serial number). It states that the Wico should simply be replaced. I imagine that made for some unhappy customers! Since my set is well after the change, it is evident that my magneto has been replaced with the older Wico at some point...

Interesting trying to find a piston ring set. There are of course outfits that will make them to order. Don't yet know what that would cost.

Am looking into the Hastings ones right now.

In July ASAP had TWO sets listed that Chris found for me, and now they're gone? Hard to believe that there are not only that many of us out there that have these sets, but that many that happen to be overhauling them at this particular moment lol. I did not want to order anything until I knew for sure I'd be able to actually use them.

Keith, I called Hastings and they said they have them, they are like 110.00 On the plus side they are new, If your bores are still standard. When I bought mine from ASAP, they were close to 50.00 NOS STD. I still haven't found my used ones.

After digging all around on the 'net, I ordered a set of Hastings rings from PerfectEngine.com, total about $103 including shipping and being looted by Commiefornia. I had hoped that the costs wouldn't balloon so much for this one, but it is what it is, and with those rings being SO worn, it would be foolish to do all this work and put them back in.

I'm glad you found a set. Sorry I couldn't be more help. At least that motor will be running when last taxpayer leaves the state.

Core plugs... I don't know that I have ever removed or installed one.

Just drill a hole and pry them out? And tap in the new one. With or without sealant?

I *assume* these are standard sizes? I do want to have the new ones in hand before pulling the old ones.

I believe they come in brass or plated steel. I would think brass would be preferred?

I want to flush out the block *really* well, as was suggested.

Keith

The great recession softened me up, the lingering effects of it still are felt.
It does not make sense from a financial side to give money or time to help those people you speak of but I gladly pay my taxes and give what I can in charity.

It is very easy to fall into the trap of anger and resentment of those in need with their hands out looking for help. ( numbers seem endless )
But until you walk a mile in their shoes you can never really be sure what its like or how they ended their.

Be kind and generous, be thankful for what you have and never forget how easy it its to lose.

I agree with you to a POINT. I myself almost lost EVERYTHING, (Wife, Kids, Home, JOB) 19 years ago because I couldn't quit drinking. I could of easily said to HELL with it all and hit the streets with my hand out letting the "System", Tax Payers, take care of me until I died.
I DID something about it. I got sober, changed my thinking, keep working on it and stayed WORKING and paying MY taxes. I am with the same woman now 41 years, kids are heavily in my life, still in the same home 39 years and I retired from my job at UPS after 30 years.
What I DO NOT agree with is what is becoming generational welfare. Able bodied people pan handling and living off of the system that OBAMA set up because they grew up that way.
I AM FOR helping a person or family that is down on their luck.... BUT, they have a definite TIME period, 6 months to a year, to get off of their ass and get back to work and taking care of themselves and family without GOVERNMENT assistance. They cannot use the "System" of welfare or such for 5 years.
Life isn't always easy. I was seriously injured at UPS when I was only 31 and only 8 years employed with them. I kept my "Jock" pulled up and worked another 22 years injured, while seeking medical help, because I was not going to lose what I had. I'm 66 now
There are definitely folks that will never be able to work due to total disabilities and those are the ones I have no problem helping.

It took 10 years for the economy to start to recover.
Still we have not returned to our previous standard of living and we lost a decade of any further gains.

Some people may never come back from it at all.

But... What about the core plugs? Gosh fellas, I hope my poor, "old" Kohler doesn't wind up in Smoke and Flames!

To me, these things are mostly quite clear. You can not take from one man by force and give to another without violating the rights of the first, no matter the "needs" of the second.

PRIVATE charities? Absolutely! So long as they are transparent as to how much money is going to "administrative overhead". But this is not the place or purpose of government.

Keith.

On the frost plugs. I usually drive a hole with a small chisel. Pry them out with a screwdriver. Sometimes they'll roll right out, sometimes they don't, especially if the centers have been thinned out. Clean up the bore and drive the new one in squarely. A socket works well. I use a dab of rtv in the bore.

I've always used the soft metal plugs. Don't know if it makes a difference.

I've never had to replace plugs on any of mine. I don't remember any postings on anyone who did. I believe they were a fairly robust plug.

Did you have coolant or corrosion issues with the block. water pump or radiator? If not, you might want to let it be.

I can see why you want to cover all the bases if this generator is going into the belly of your bus.

Good luck.
Jack

vanman, Are the freeze plugs the "CUP" style or the disc style? If you have the cup style then the best way to install them is to get a socket that just fits inside the cup and use it to drive it in. I have put a thin smear of permatex on the OD of the cup before I install them. If you can get brass, that would be better.
