Oliver 880 diesel

thuntley · Nov 3, 2009

I have A 1959 Oliver 880 diesel with the 265. I have read about the 950 having a 302, it has a 4in bore where my 265 has a 3.75in bore. Does anyone know if you can bore the 265 block out to fit the 4in sleeves out of the 302. Thanks

yes you can will have to bore block for over size sleeves can go to 4.250 fairly easy all it takes is money with out boring block 3-7/8 is biggest sleeve you can get not hardly worth the trouble though JD 4020 sleeves are 4.250 and is what every body uses

You can't use the 302 sleeves. The 302 was a dry sleeve block, and the sleeve was just a thin replaceable liner. If you tried to put that in the 880 wet sleeve block, assuming you still want to have water in the block, they would not be near strong enough to take the cylinder pressure. I've done a couple 880 diesel engines at 4.250 bore, 4020 sleeves have to be turned down to work, then they are too thin to be strong enough on a diesel because of the material they're made of. Also, 4.250 sleeves cut back on water flow, so they can't really be farmed with, just for pulling tractors. What are you going to be using the tractor for? that makes a big difference on which direction you should go.

So out of your two replies I get I can use 4020 sleeves cut down but the tractor would be only for pulling because of a heat issue, right? So if if do go this route, and I know this is a stupid question, I probably have to use the 4020 pistons and what to use to hook to the crank? How much more cubes could I gain doing all of this? And hp? Could I use it for light duty farm work such as raking? Will it turn heads at the track? (lol)

I'm not sure why you want to go to a 4.25 in. piston on your 880. If you do you must use a ductile sleeve, not a 4020 sleeve. Most machine shops will charge you $100/hole to inlarge your block and another $250/hole for the ductile sleeves. Why don't you take a 310 diesel piston, mill it down .035 and use the sleeve that comes with that kit. It will give you a 283 cu. in., with about 70hp.

ok i am planning on pulling the tractor most of the time but would still like to he able to use it in the field to do some plowing and other stuff, so what would be the best and easiest way to get more power and still be able to use it in the field

I'm building a 1955 Oliver super 88 diesel for tractor pulling. I was wondering if I could bore the block out and put the 4020 pistons and sleeves in.
