Diesel Forty engine

Yes, they can be frozen. I have some that I'm thinking of cooling with dry ice to get them moving.

I have removed liners using a hydraulic jack on the ground and using a suitable bar , pushing them out from underneath.
Also we need photos of your machine.

Thanks guys,
I’ll try that Stephen.
The only problem is Andrew, the engine is off the machine.

If the liner is unusable. Run a few heavy beads lenthwise inside with a welder. When it cools it should come out but it will be junk. I have never done it but I have seen it done succesfully

ok just be careful you can set up a hydraulic puller from the top using a hollow hydraulic cylinder with the proper size rod and bottom plate the o-rings are dry and stuck to the block there is most likely a lot of sediment in the bottom of the block i would pull all the sleeves and have the block boiled or cleaned

I have seen the welding work. I believe they came out without any pull gear but it was years ago.

Diesel Forty engines are 5.25 bore, I would be trying to save the sleeve if at all possible because 5.25 stuff is very hard to obtain. They are a very thick sleeve, I have heard of them being machined and a thin press/shrink fit sleeve fitted into them.

That is an interesting idea, and why I try not to throw out very much because I think it is bad today. I guess since the sleeve have ID wall side reliefs for the valves it would have to be blind bored from the bottom to stop just above ring travel?
If anyone has done this please chime in!
