3 5/8 diesel piston

Would anyone have a set of these or similar. They are flat diesel pistons. Need 40 over or 3 3/4.

You have to state what for because of other factors like wrist pin location ring width. It doesn't just go by bore diameter.

I have all specs but original piston discontinued years ago. 1.250 pin diam. full floating. Comp height 2.415. 3 compression top 1/8 next 2 and oil 3/32.

If your pistons are OK, but block is worn, you can sleeve the block.
Oliver used flat head pistons with 3-5/8(550/770) or 3-3/4 (88, 880) with 1.25" pin diameter. But the compression height is less.

It would be easier to look up in my large library
of parts books if you gave machine,(tractor?)
make and model, or engine make and model!
3-5/8 is meaningless, it could be for a hundred
different engines of that bore, all with varying
piston specs.
