Hello The engine was pretty tired in our 230 and we would like to rebuild it. We were wondering what the biggest size sleeves and pistons we could use and where to get?? also flat tops or aluminium step??? Would a 340 engine kit fit? I have 5 1/4 valves. Were just trying to get as much power out of it as possible and hopefully only to the job once. Thanks for the help in advance.

Looks like the subject has been cover pretty well. Listen to Stan (VA), he's forgotten more about Farmall's than I'll ever know. My 230 has the C-123 with IH FireCraters (factory High Altitude Domed Pistons). Dyno'd at 32HP. I've not been able to "choke it out" before it spins out with a 2 bottom 2pt plow pulling as deep as it will go. I wouldn't temp fate and try for too much HP as you will probably be needing a couple or more bull pinion gears if you do. Ever pull a letter series X30 series Farmall trans??? You may have to learn. Don't mean to be snide but the IH engineers probably knew what they were doing when they designed everything together. Good luck with your 230. They are great tractors! Bobg in VA

Take the engine apart. Pull the old sleeves. Measure the inside diameter of the bore at the bottom where the O-ring seal seats against the bottom of the sleeve.

That inside diameter will determine which sleeve sets will fit into your block without machining. Know that mesurment when you order a rebuild kit.

You will need to measure those sleeves as Stan suggested. If you go to aicatalog.com and look at their sleeve kits, they have the C113 and the C123 engines listed for the 230 tractor. I thought they all had the C123 engine and you could
boost the cid to 133 without any machining to the block. Hal

I would think that you could put a set of 3 1/4 bore sleeves in the block and that should come up to about 133 cid. I know a guy that pulls a Super C with the motor and he is about 38 plusHP with the domes pistons.

ok well new super c engine kits increase to 3 1/4 and 340 330 are 3 1/4's. Not sure which one to go with? I think they should be the same sleeve setup being the same original block right?? where do you find hi-comp pistons?

NO! w/o custom machining you're not going going to get Super C sleeves in your block, and C135 sleeves are not interchangable with them.

Below is a quote I found from an earlier post I made related to the subject, search the archives and you will find this has been covered quite a bit.

06-17-2004 .....
The 251069 block has 3-5/16" sleeve OD (at the O-ring) and originally had standard sleeve and 3" bore (C-113). The overbore kits are thin sleeve with 3-1/8" bore (C-123).

The 354898 block has 3-7/16" sleeve OD and (we now know) came in two standard configurations: 1- standard sleeve with 3-1/8" bore (C-123 Super C); or 2- thick sleeve and 3" bore (C-113 in late Super A). The overbore kits are thin sleeve with 3-1/4" bore (~C-133).

It gets more interesting when the x30 series came out. 130/140 and 230/240 tractors came with C-123 that used the thin sleeve 3-1/8" piston/sleeve set from the factory (3-1/8" bore and 3-5/16" sleeve OD). I have been told that IH's overbore kits for the C-113 would not interchange with the factory kits for the x30/x40 series, but I know that the aftermarket ones do interchange. My guess is that they changed the depth from the bottom of the sleeve that the O-ring seats at and the aftermarket kits handle the deeper ones so they can be used in either?

My 230 has block number 366204R1 eng num 39465; my spare 240U block is 367825R2 eng num 75014; my 140 block is also 367825R2 eng num 101390. The parts book shows a change at eng num 65000. I assume that is the 366204 to 367825 block change that changed the front of the block for the new style water pump and they received the new style crankshaft that used a nut to hold the front pulley on instead of the press fit system. This new pulley uses a thinner fan belt also.

The important thing to remember is that you need the sleeve OD when ordering sleeves, it should be one or the other and most kits offered today are all the overbore thin-sleeve kits either 3-1/8" (for the 251069) or 3-1/4" (for the 354898). It does help to pull the old sleeves and measure because of the possibility of custom machine work being done over the years. I know of several C-113 blocks that were bored to allow use of the 3-7/16" OD sleeve kits.

Well my Super A is a 52 and it had the 3 in bore sleeves and they were thick wall. Now it has the 3 1/4 sleeves in it and the block didn"t need any machine work done to it. It already had the 3 7/16 hole in the bottom of the block.
You can have the block bored to the 3 7/16 size but then you need to take some time and do some fitting with the O rings so they fit in the block.
I picked up my sleeve kit thru a Tisco dealer.

thanks for all the help guys. I need to check the numbers on my block and pull a few sleeves and do some measuring. I will let you all know what I find. If I wanted to have custom mach. work done and fit bigger sleeves yet where would I find kits like that. thanks again
