Guide to Sleeving Engine Blocks

- There are many ways to install cylinder sleeves in an engine block however, we prefer to use liquid nitrogen to freeze the sleeves allowing us to drop them into the block.

Nice work.
Thanks for sharing.
Take care, Ed.
Really enjoyed your video. We have a Rottler similar to yours, not exactly the same. Our cutter setting fixture uses a traditional barrel type micrometer, which moves the anvil .050 per revolution, rather than the standard .025. It’s easy to make a mistake. I put the sleeve in the freezer and warm the block in the oven before installation. Probably overkill, but I don’t want to get stuck pounding with a hammer. How much of an investment is it to get set up with liquid nitrogen? Also, how much material do typically leave for a shoulder at the bottom of the cylinder? Not even going to ask how you drilled the crack within the limited space of the cylinder. Keep sharing your knowledge.
It's not too bad with the liquid nitrogen. I think a large 20L dewar like we have was around $250 on amazon and I get the nitrogen from my local welding supply house which is about $50 to fill the dewar up. I like to leave around .150-.200 of a shoulder at the bottom depending on the block. The two holes really weren't that bad to drill. I have a tight right angle drill that takes its own drill bits so it's easy to get in there and drill them.
@@pageracingengines Thank you

How long does it take to immerse the cylinder sleeve in liquid nitrogen?

beautiful and professional work .I subscribed and liked the vid .more automotive machining pls
Dose the cutting of the sleeve in the block help provide a "Friction Fit" for the cylinder block bond?
The block is cut to provide a press fit on the sleeve and then once the sleeve has reached room temperature we can bore the sleeve close to the final bore size before finish honing.
Is .001 enough with the variances in the sleeve? She went in super easy. Neat work btw 👍
Yes, that is why we measure at so many different locations on the sleeve to find the average. It also helps that it's an iron block so the sleeve and block expands at basically the same rate as they heat up.
Do you know how cold you're going ? as you are able to go colder than cast iron is really ok with using nitrogen
Not exactly. There's not a lot of press on the fit so the amount that it shrinks/chills should not get to the point of damaging the cast sleeve.
Great video 🙂👍
What kind of press fit do you shoot for?? nice looking shop brother
We typically shoot for around .001 press fit in the block but can vary based on sleeve type and block material.
@@pageracingengines thanks for reply! what about a flanged sleeve?
@@3m1n3mx31 Its basically the same except there is no press fit on the flanged part of the sleeve
Shoot for lease one-and-a-half to two and a half thousand
I have a 2013 zl1 6.2l aluminum stock block that needs resleeved . Who do you recommend or could you guys do this for me and what do you charge for this type of work. Thank Dennis
We can handle that. Give us a call at 864-574-2151 and we can discuss options and pricing.
It's setting at slowmotion motor sports shop . I can have them call you and talk to you about that too .
Slowmotion motor sports told me they are going to call you to set up the shipping and cost . So I can pay the bill
Slowmotion motor sports is trying to get ahold of you guys and nobody is answering the phone . It keeps going to message machine.

Do u need to coat the new sleeve with Alusil or something?
No they are cast iron and designed to be run uncoated.
Do you only work on LS engines?
No we work on other engines as well, just your ford dodge and Chevy v8 engines.
How much does it cost to sleeve 1 hole lq9 Chevy 6.0l?
Typically it’s 150 for the labor to install the sleeve and size it not including the cost of the sleeve itself
OLÁ Page Parabéns por tentar melhorar. Quem o está impedindo de executar um trabalho perfeito provavelmente são as especificações de fábrica. O uso de nitrogênio líquido impede o trabalho perfeito. É frio excessivo a ponto de alterar a dureza Rockwell para maior e, se não montares imediatamente e retornares a temperatura ambiente verás que houve pequena diminuição no diâmetro interno e externo. As alterações são a nível molecular. O correto é o uso de GELO SECO, misturado ao ÁLCOOL. Forma uma pasta LUBRIFICANTE. O Gelo Seco tem -76° C e ao misturar ao Álcool passa a -48°C. (com nitrogênio a umidade do ar forma uma camada de gelo que dificulta o encamisamento.) Muito importante encontrar a medida correta da camisa, é normal estarem deformadas. O assunto é bem maior. Abraços...Roberto Udo Krapf
OLÁ Page 07/09/24 Como não comentastes não sei se lestes. Em referência a forma incorreta que usas a "plaina" demonstra que a máquina está mal regulada, e ou desgastada, e ou com defeito de projeto, e ou com manual do fabricante errado. Abraços Roberto Udo Krapf
Do aluminum sleeves T6 6061 withstand high horsepower?
Aluminum is not a common material used in sleeves. Sleeves are typically made of ductile iron which gives a stronger and tougher material to handle the higher horespower.
@@pageracingengines I appreciate that you answered my question 🙏🏻Do you recommend dry or wet type? For the tb48 engine, I am working on this engine and I have a goal to get it to 1500hp / NA Nitros
No sleeve retainer "juice"?
When sleeving an iron block, the retaining compound is not necessary since the expansion rates are the same and we also use enough press so they won't move around.
I would rather hear the machine than the music, it's more telling of the process
Can't see honing process
Your not blind, just deaf. He said Next Video .
Makes me wish I had taken machinist course in trade school instead of electronics.
