sleeveing blocks with no crush?
Somebody was telling me recently about a chemical used for filling in the gap and setting cyl. sleeves using .002-.003" clearence rather than a press fit. Supposedly used on honda blocks. Anybody know what this chemical is or who makes it?

There are quite a few different Loctie products you can use depending on amount of clearance, temperature, bond strength, cure time, etc. For the LS motors that have a very light press fit (.0005" or less), you can use Loctite 515 on the bottom and sides of the sleeve, and Loctite 620 or 640 around the top.
You can also check with Steve Demirjian at Race Engine Development in San Diego. He has a lot for knowledge in sleeves and works closly with Darton.

We used to use this stuff called litharge used to get it at the drug store mixed it with a liquid it made a paste we smeared on sleeves and seats before fitting. I dont remember what the liquid was, nor do i know if the powder is still available , but its a lead if your interested.
Re: sleeveing blocks with no crush?
K-Line use to market that system. I never got up the nerve to try it. They said it would hold better than several thousands interference fit.
Another shop close to me used the system and he swore by it.
I did a web search for them and couldn't get any thing to come up.
I know SBI has taken over the K-Line Bronze liner line. (try saying that three times real fast ) so they may not be in business anymore.

Re: sleeveing blocks with no crush?
Thank you, I will try K-Line, I am making some sleeves for a throttle body and its bored so big that I am afraid it will break out if I press them in. I knew I could count on you guys!!!

John, .0015-.0025" crush, freeze the sleeve (apply loctite before freezing), heat the throttle body and assemble quick! Also I did see at PRI show years ago someone was marketing a process to install cylinder sleeves in blocks. 2-3 thou clearance, used a primer on sleeve od and block id applied with a foam roller. Then apply a super strong, heat resistant thick super glue with no voids, slide the sleeve into the block turning back and forth slowly. You had to use something to hold the sleeve in place while it set up.

I haven't ever ran acrossed "miracle glue," but it might still be out there, probably next to the can of rpms.
I cannot think of one application where you wouldn't want a press fit, except no bore micrometer.
Done hundreds of sleeves and rarely had problems.
All must be held in place while temps "normalize."

Re: sleeveing blocks with no crush?
No luck finding K-line but came up with my own formula and seems to work good for what I am doing. I am pretty sure I wouldnt do this for a cyl sleeve in a block even though in some cases a press fit is kinda risky. What I have is a Hillborn 4 hole bored out to 3.290" and I am sleeving it back down to 3.125". If you have an old 4 port sitting around measure it up and you will see how thin it can be.

Re: sleeveing blocks with no crush?
Cant relate any experience to cylinder sleeves, but have used a product from Loctite to install "loose" bearing races in HD construction equipment. WE called IT " green" because of its color. I cant remember the part number of the stuff. but it is used with a loctite primer and a layer of this green stuff. I can say that it absolutely works. After many overhauls of HD equipment , the races NEVER loosened up. Only thing about loctite products is you use heat to loosen it to get it removed again. Cant say from experience on sleeves, but maybe a call to loctite will be enlightening.

Re: sleeveing blocks with no crush?
several loctite products are up to the task. Best choice is probably # 620 high temp bearing mount. Up to .015" gap, 450° F., 3800 psi strength.promachine wrote:Thank you, I will try K-Line, I am making some sleeves for a throttle body and its bored so big that I am afraid it will break out if I press them in.

Re: sleeveing blocks with no crush?
I used to use the Kline glue on OLD single cylinder 1900-1910ish jugs mainly. Had to leave about .0015-.002 slip fit. I was too worried that the block would fall into pieces with all of the lead soldier and welding that held them together if I were to use a press fit sleeve. I never had one move, but I got to thinking after the third or fourth one that i ought to put a screw in pin in the bottom of the sleeve to be safe, slept a little better. Since Kline went away, I use the Loctite 620, with a slip fit and a retaining pin and it works well. However, these engines are making only about 7 or 8hp!
Some company came up with the idea of using super-thin liners held with superglue. I forget their name now. I was *very* interested, having a collection of .040 and .060-over 400 Chevy blocks in the scrap pile that could have been turned into money. I traced the product to K-Line, who had bought the company before their press releases hit the magazines, and followed up a few times, but as far as I know they never hit the market.
Re: sleeveing blocks with no crush?
without interference on a cylinder sleeve i would think the heat transfer coefficient across the glue would be pretty critical

loctite 620 will be more than adequate for a throttle bodypromachine wrote:Thank you, I will try K-Line, I am making some sleeves for a throttle body and its bored so big that I am afraid it will break out if I press them in. I knew I could count on you guys!!!
Is the cylinder sleeve question separate issue?
