F-12

Coax · May 22, 2008

OK,
I've looked thru the archives and every book I could put my hands on.I could'nt find the definitive answer.What engine did they put in the F-12?Is it the C113? I think I'm on the right track but the Blocks dont' look the same. Mine has a sizable hole in the left side and it looks like Replacement time,so i'm gathering Info now. Thanks as always in advance!!! :?

The F-12 has a C-113 engine.

anks Andy,
Next silly Question. I know of all the known ways to fix a crack in cast metal blocks and such, but what if the problem is a rectangular hole aprox. 1"x3"(Looks almost like a blowout) on the Left side Water jacket?
My question is "Can you Patch a hole like that? Say with JB Weld and a Plate over the Hole? Is the Water Jacket Pressurized?I know the newer engines are, I don't know about something This old??? Or is it make a planter w/it time? :?

Andy Motteberg · May 22, 2008

I have seen the large hole like that in the water jackets before and they can be fixed, but I have never done it myself before. I know a person who restored a F-14 that has a thick metal plate bolted to the side of the block. I don't know if JB weld would hold a metal plate on or not, I've never repaired one yet, but I do have to repair a crack in my brother's F-12's block.

I run an F12 with a patched block on the fuel pump side towards the front.

The F12/F14 do not have a pressurized cooling system.

No pressure in the system, if this is a "play" tractor almost any
kind of patch will hold. Try making a plug exactly the same size
as the hole then weld a piece 1/2" larger (all sides) to it JB the 1/
2" flange slap in the hole and go. Could even tap and put
screws in the corners.

Bob Kerr · May 22, 2008

I have seen very few F-12s that didn"t have a repair to the block on the left side and I have seen a lot of F12s! The block was welded up on mine. Must have been a design flaw more than careless freezing.

The whole F-12 was a "design flaw".

James Williams · May 23, 2008

Coax,I bought my first F12 with a hole in the same place that was repaired with a peice of copper over the hole,I took it to a welding shop and he welded a peice of steel in the hole,He said it welded like a virgin peice of cast,It never leaked.A friend of mine bought a F20 with a hole you could stick your head in and filled it in with some kind of 2 part expoxy,sanded it down and you cant tell it,and he works this tractor.

Thanks to all!!!!

The F-12 used a 113 cubic inch engine, but it was never called the C-113. The C-113 was used in the A and B (among others) and was totally different.

steelfronts · May 23, 2008

Tom It seems like you never let a chance go by without blasting the F12's and 14's. If they are so bad how do you explain sale of over 125000 of them and the fact that so many are still around? They will do more work than any team could and cost less to buy and maintain. The $575 that was spent for a new one was the best money ever spent.

What, in particular, was the "design flaw"? The cracked blocks are a result of using water as a coolant during the winter, as a good antifreeze was not available at the time.

I'd like to hear your opinion on what the biggest problems were with the series. Thanks!

Athol Carr · May 23, 2008

The F-12 engine has a weakness in the bottom of the water jacket above the fuel pump. My O-12 had a crack there, it did not leak but was noticeable. I had the block stripped, took three sessions in a hot-tank to get the sleeves out, and the crack welded. You have to look very hard to see it now. I have seen lots of patched blocks, one with a copper plate riveted on. A ready supply of anti-freeze in the old days might have been useful. The engines have one other fault, the push-rods did not allow the spark plugs to fit between them so they are on the other side of the engine under the manifold where they are hard to get at, ordinary plug wrenches will not fit and they had to use a down-draft carburettor with its fuel pump. This is fine once started but unless one has the starter tank above the engine (only on kerosene or distillate) with its gravity feed, if they have been sitting for a while it takes a lot of cranking to get the carburettor full of fuel so the engine can start. The engine is 113 cubic inch but was not the same as the C113 engines in the Farmall A etc. I believe the pistons and sleeves from a Farmall A can be fitted but the bottoms of the sleeves need some modification

I made a mistake, I meant to say 113ci.

Andy Motteberg · May 23, 2008

The F-12 was not a "design flaw". If you cannot say something nice about a F-12, you don't even have to reply to a F-12 post!!

Andy Motteberg · May 23, 2008

Very nice F-12 Steven! We have 2 F-12's, very nice tractors to have.

Andy.

Thanks for the compliment! We also have an F-14...

Andy Motteberg · May 23, 2008

Nice F-14 too! I don't have a F-12 or F-14 yet, one of our F-12's is my Dad's, and one is my 3 year old brother's F-12. I'm going to pick up a 1938 F-20 in June.

Coax · May 23, 2008

Well Okay ...So your saying its not a C113???Okay now I"m confused.What is it called in IHese? I"ve got a "IH 4 Cylinder Carbureted Engines Service Manual" that lists all of the 4 bangers IH put out from the 60ci to the 335ci.and according to Hoyle..a 113 is a 113.And the only difference between that and a 123 is sleeve/Piston size.Please enlighten???

Coax · May 23, 2008

OH Yeah hey Steve what color is that on your F-12?? Is that 2150?
It's Not the same as the color on the F14???

Couldn't tell ya, they were both done around 91 or 92. Should be the same color, could be the quality of the picture, daylight vs. light bulbs in the shop, etc.

John M · May 24, 2008

Ill bet your ma and pa thought you were a design flaw too! Why do you continually bash the 12/14s? Did one try to molest you as a child, did you try to molest one as a child? WTF is your GD probelm with these that you must bash them every opprutunity you get? WHAT IS IT? I suppose any other tractor from the sme era,and same HP bother you too, huh? No, well then shut the he!! up!

moseed · May 24, 2008

OUCHIE, I have and love my F-12's, have three and a W-12 and an F-14. While only the 14 and two of the 12's run I can say I'm glad I didn't have to use them 12 hours a day. It's all relative, my son was driving our IHC 15-30 awhile back and did not put more than 45 minutes on it. We do that a couple times a year to keep seals sealing and such. He was really appreciative of the F-12s and F-14 after that. The wonderfull result is his (20 years old) appreciation for the old boys who used to wrestle those things day in and day out. They loved them for the ground they could cover and it seemed the long wrestling matches were well worth it over horses. It's all relative.
Some of us apparently take it emotionally when a favorite peice isn't as appreciated by some as by others..it's all realative.

John M · May 24, 2008

Nope, just tired of him bashing the tractor. Same thing as me saying a John Deere H is worthless without any reason why I think that. I made a comment along the lines of it being used for what it was designed for. He made some kind of smartaleck remark about it. While I can agree everyone is entitled to their opinions, but he continually knocks this tractor at every turn, and as I said, Im tired of it.

Hi, i have several f-12 & f-14. only 2 with cracked blocks. without antifreeze these had to be drained after every use.Both of my grandfathers farmed with f-12s. The only complaint i ever heard them mention was, if you killed them hot they would vapor lock.i think that is why you may see several gaskets stacked under carb. very easy to operate and haul. thanks Steve Il

Farmallgray · May 27, 2008

As far as I know, the F-12 engine was just called the 113 ci F-12 engine. It didn't have a model number or name. The C-113 was used in the newer models (A, B, etc) and was a completely different design. You will need an F-12 service manual for specs on it.

Coax · May 27, 2008

Thats the thing I'm Struggling with.I have the service manual that supposedly covers every 4 banger IH made(with specs)from 60 to 335. The 113 or 2a Series are same same.I just don't want to start ordering parts for this thing without some sage advice from the gang about whether I'm looking for the wrong part ###.I know that some won't be found for love or money, Just don't want to go In the wrong direction. But Thanks for the info!!!

Search google for Rice Equipment, they will steer you in the right direction.
