Sleeve pullers

Dave H (MI) · Sep 12, 2021

Just getting my ducks in a row. I have been looking at the 300U sleeves while waiting for some tools to arrive and I am thinking they look pretty bad. So I am looking into the tools required to replace the sleeves. I understand the concept...a correctly sized puck on the bottom, threaded rod and a nut supported on the top...etc. I can handle most of this but I cannot turn the puck. I have a lathe but it is in storage. I have been glancing about the web looking for something I can buy. Hoping someone has experience and/or recommendations. Point me in the right direction, give me a good hard shove.

Its been a long time since I changed the sleeves in my 300U but if they extend down past the bottom of the block an oversized puck will pull them loose and I'm thinking once loose they will pull out as they are dry sleeves and shouldn't have rust on them. I just did my Super C like that but they are wet sleeves so using the oversized puck I got them loose and then I could just pry them up carefully.

I will have a look. Thanks!

Anyone got a service manual can verify that I am understanding that the bore is 3 9/16? Left the darn thing out to the shop. If so, that is the diameter of the hole in the block, yes? I will mic the inside of the sleeves.

Dry sleeve have to pull all the way out or close to all of it. Regular threaded rod will be far short of stout enough for pulling dry sleeves. Dad had an axle shaft threaded to pull the sleeves on his MD 40 years ago. I would mike my new sleeves for a close fit to the outside diameter.

No to ID of block, from look of pistons in picture you posted it has 3-5/8 pistons with thin wall sleeves. Bore of block with no sleeves is 3.749 give or take a thousand or two. Standard size piston and sleeve sets sold for a 300 or 350 for 50 years or more. You want the puck to be close to block bore ID but not to tight. Then part of it to go in ID of sleeve. I found most of those sleeves measure 3.6220 to 3.6230 ID when installed. Make just a little smaller than that. If wrong about your pistons and it still has around 3.561 ID sleeve part of above will be off. Bit of piston top I could see looked like a fire crater piston set though. Don't know if pistons are being replaced or not. Depending on the engine serial number the connecting rods could have one of three piston pin bushings. standard bushing for a big piston pin. Adapter bushing in big end rod for a small pin and a standard bushing for small pin in small end rod. If you have the 3-5/8 pistons it would have one of the last two.

I just made this one for a 3.062 wet sleeve . It is the way I machine them as this design will work with the OTC sleeve puller components , this is what the OTC plugs look like only they are cast and then machined accordingly. they are designed in this manor so that the plug can be passed through the sleeve from the top.

I could turn one out for you , I'm located in Mich also. If it is a dry sleeve, the plug really should be about perfect and my experience as been with dry sleeves if you don't have a hydraulic puller you are going to work your butt off pulling them with just a threaded rod and nut and it should be fine threaded rod .

I have some misc OTC components that I may sell and then show you what you'll have to make to get the puller usable . Email is open
