SD220 060 Pistons

Yep, I've gapped my rings over the years on different engine rebuilds the same way Kevin describes. Slow and fiddly but they always came out right and I wasn't on the clock so I enjoyed the process. If I did it for a living then I probably would be looking into more tools for that job.

nrowles,

If you are still looking for pistons I just ran across a lead for you. It from
"International Harvester S-Series" on Facebook

Rob Hoogmartens Jimmy, where did you buy the oversize pistons for the BD-240 engine?

Jimmy Jacobs From Charlie's IH in Chillicothe Mo. he has a really good selection of IH parts and lots of manuals and a lot of knowledge and love for most things IH. Charlie's IH on facebook

I am not sure of the date of the original posting. If it were me, it would be worth a little googling to get a number and then make the phone call. FYI, he had .030 pistons.

Thank you. I don't do Facebook but I'll figure it out. I would assume the Charlie you reference is the Charlie in MO that Tom Underwood gave me a # for and it turned out to be incorrect. I will try to find him on Facebook.

Charlie has quite a few parts, I can give the number if you PM or email me. I will not post his number on the internet. I would think he is the last guy around with a large assortment of parts, I bought parts from him for some time. Good guy, get parts while they last.
I have given his number out before, about half the guys here never call him. Oh well.

I found him on Facebook and called a couple hours ago. He was going to look and call me back. At this point I'm assuming he does not have any and he was going to make a couple calls before getting back to me.

set of .040 over pistons on eBay

I've been in contact with a dozen old IH parts dealers to this point and nobody can find 60 overs. Now the shop is telling me one of my pistons looks completely different than the others and weighs 43 grams different. Guess I'm on a search for any good pistons I can find.

The only pistons I see on Ebay are stepped on top and mine are flat.

If they are stepped head pistons for an SD, I'd suggest snagging them. Around 1954, IH upgraded the SD220, going from flat top pistons to the step head. Same connecting rods, block, head, etc. The only other change was a smaller exhaust manifold diameter. Upped the horsepower a bit. SO if you have flat pistons, the stepped heads should give you a little more performance.

I could be off here but I thought the stepped ones had to do with the valves. I have straight valves and then shortly after they went to tilt valve. Are you saying the stepped pistons are "drop in ready" with my straight valves and don't need any work done to them?

I have learned a lot about these old pistons. So far no solid leads but lots of facts.

In the different books I have looked at there is a engine number cutoff. Best I can tell (its not spelled out) this has to be related to tilt/straight valve engines. The pistons specs are the same. The later model motors have slightly more horsepower (~4,10,13 HP for 220,240,264 respectively)

The pistons are 3-9/16 diameter (3.5625) with 4 rings (3 compression and 1 oil control), 3/32" top, 1/8" 2nd, 1/8" 3rd and 3/16" 4th. Wrist pin diameter is 0.8748 to 0.8750 essentially 0.8750" or 7/8" diameter. This four ring setup shows up as a ring set with Hastings Piston Rings as part # 2C5047.

You can go to Summit Racing and type in this number, then select 'applications' and get some diesel IH/Case motors and some 50's era GMC trucks as using these parts.

There is also mention of a 'high altitude' (5000 foot or LPG engine) piston in the parts books. I wonder if this is the dome piston that is being discussed. Std compression is 8.5

I was looking in my MT-103 catalog and it shows pistons with 4 rings. My IH truck service manual for the 'S' light and medium duty 56,57 has a spec sheet with 3 rings, 3/32", 1/8" and 3/16" This lines up with a Hastings #2C5280 which comes up as 60's era IH inline 6's. I'm not sure which one to trust. 3 or 4 rings?

You can also search on Summit Racing by piston diameter. I did for 3.563 and there are 48 matches. I did not look at the specs any further as I thought I was looking for 4 ring piston, but now that I think its a 3 ring, there might be a close enough match.

Since you are boring out the motor block that might give you more options. Just need to do the math. I would consider pistons from 50's era GMC, Chevy, Ford, etc Start looking at the specs.

The one last thing that I keep wondering about is if there a 'agricultural' angle that might help. I know IH used essentially the same size motor in a whole lot of applications.

Food for thought.
