I think I will try dry ice!
I have been told that if you re grind the valves and valve seat you need to grind the top as well, just to make up for the increased compression room when the valves and seats are grinded further into the top.
A friend working for Massey Ferguson told me this. A new overhauled motor was hard to start due to less compression after valve grinding. Grinding the top solved the problem. Anybody else heard if this?

I have pulled alot of liners out if isuzu engines that way, works pretty dang good. I love the puller you made,looks just like the one we used less they hydro. set up.
the dry ice is fun to play with when your done to, put a little in a plastic bottle with some warm water, screw cap on and through as fast as possible cause its gonna blow.

Removed the valves and the valve linings today. The linings were really stuck.
I used the hydraulic press and a bolt with a rounded head to push them out. 3 of the 6 linings cracked when I put pressure on them. Should probably have used some sort of special made device to avoid that. They came out without damaging the top though. (Had some luck I guess)
Saw something else today, there has been done a welding job on the top, maybe frozen once?
I suspect this tractor has been totally rebuilt and "zeroed" many years ago.
Well, the seller made a good deal!

Many many years ago I installed a new set of liners in a Mack engine using dry ice. We opened the boxes the new liners were in, filled/packed with DI, & closed the boxes back up. When we got the last box filled & shut, we took a short break, then opened the first box & the liner just fell into the block, slick as snot on a door knob! These were, like yours, dry. A couple years later, when I was in the service (Coast Guard) we changed a liner in one of our main engines (Cooper Bessemer GN-8). These were wet liners. No dry ice involved, but lots of cleaning & lots of liquid soap on the liner O-rings.

The Broccoli metode.

Fitted new pistonbolts by the help of the kitchen stove, 170 farenheit and they slided inn nicely.
Also fitted new cylinder linings, I left the linings in the freezer for some time, while I heated the block with two lamps, put the linings in a cooling bag together with stuff from the freezer, broccoli, moose steak and frozen jam. (had the moose for dinner later) It worked fine, some light knocks, and there they were.
Had the top planed today, in a friende workshop in his basement, not much room for vegetables there!
Rolled the the motor back in where it belongs with the help of a pallet jack.

Gunnar, I think it's not a 12-step process nor a tough love bootcamp, but you are definitely curing that "wayward" tractor of its bad habits. I love your homegrown ideas for getting the job done. Nice photos to go along with the story. Thanks! Keep 'em coming.

Gunnar, I am tempted to show my wife this thread with your creative use of frozen broccoli! It is not my favorite veggie but we seem to have it for dinner way too often. Now the moose meat..........

Gunnar what a story! Wow I hope you check the transmission out before you put it all back together! Love the pictures and you certainly have a loving wife to put up with the use of the kitchen table and oven!!

First start.
Put the top back on today, complete with rockerarms and all. Bleeding the fuelsystem and trying to start. Started on third round!!
Exiting to start an engine first time after overhaul. Very nice sound to it!
Let it run to operating temperature, off with rockerarm and nozzles, last tightening of the top nuts with the torque wrench and then final assembly of the engine.
My workshop may appear messy for an untrained eye, but that is probably because you dont understand the system!
Made a special tool to press inn valveguides, just press until it stops.
Not much help from the better half, still no sighn of showing any interest. She prefers quilting!

You know I bet that quilt took as much knowledge and patients as putting that engine together.

Very nice job.
