What I found when I pulled sleeve.

Rollie NE PA · Mar 20, 2016

My buddy wanted me to pull the sleeves on his Ford 8N. The sleeve fought me all the way to the end. The little hole in the bottom of the sleeve is threaded and when I pulled it, it broke out the the little hole in the block.

A repair sleeve can be installed in the block (machining out some of the remaining block wall) with a press fit. then this sleeve is bored out for the dry sleeve. No real hardship, just a few more bucks, (or get a different block! Jim

That's what somebody's gonna find if they overhaul Dad's old one. It had a hole in it when I overhauled it last time. I smeared everything down real good with Permatex and put the new one in. It's never leaked. Never been run hard either,but never leaked.

That block is cracked. My buddy bought another block but I decided to pull a sleeve in the old block just for the heck of it.
I don't know if the sleeve was moving and someone decided to put a screw in the sleeve to hold it in place or what.

Funny you bring that up, I just pulled one last week that was getting oil in the coolant. The block was split on every cylinder behind the sleeves. There was no fixing that block, it was cracked through the sleeve right across the block deck on 2 holes. The owner wanted a better tractor, so decided not to fix it. Here it is, I slapped it back together to haul back to his house where he is going to part it out.

We never pulled a sleeve on an 8N. Those are thin wall sleeves; Ford had a special "T" chisel that you drove down on the outside of the sleeve. The "T" cut a slice out of the sleeve and you could lift out the sleeve by hand after it was cut - no damage to the block using that method.

We used the 8N over winter for chores, with lots of idling, and every spring we had to put in a new set of sleeves and pistons. Pull the head, remove the pistons, and split the sleeves. We'd remove the pistons, put the sleeves in the deep freezer for an hour so the sleeves would drop right into the block. Once the sleeves warmed up, they were locked into the block.

This block had sleeves that were .125 inches. The other block had the thinner sleeves.
