dropped sleeves

[CONSERVATIONMAN]

New to 8n, just got this one with a frozen motor.

The #4 exhaust valve was frozen open and the motor froze

the #1 and 4 cylinder sleeves stuck to the pistons and went down to hit the crankshaft. I was able to get them out

Does this happen? There isn't much of a lip to hold them in

the tractor was being worked on but the owner passed so i don't know what he was working on.
Is it possible to put-in the wrong sleeves?

thanks
Wally

Yes, sleeves can drop and tangle with the crank. Some hear a knock.
.040 sleeves came with early 8ns with a star shape preceding, and then following the serial number.
Ford changed the symbol to a diamond on later 8ns designating .090 thick sleeves.
.040 sleeves dont have much of a flange.
Blocks are .001" less than the sleeves, so they should not just drop in.
Many use modern sleeve retainer to "glue" if not enough interference.
Here are our host's listing, with dimensions.
