H head cast#

lo HP IH owner · Jan 23, 2011

My head is stamped 8776-d. Is this a All-fuel head? I'm guessing, I have the extra hole in the hood, and not got to much compression. I'm hopping its the hood. THANKS for the info....

I know I was told the 8776 DA cast number on my H is a kerosene head, but it still seems to have pretty good power. I am not sure what the D alone means. I have an extra 8043 DC gas head, if you're looking for one send me an email.

That is a distillate head. If it just has a D following the number, you have a early H if the head is original to it. If it is a early H the frame rails you wanted to change in the other post may use the rubber mounts between the engine and the frame rails. IH went to solid mounts between the frame rails and engine because of frame rails warping in around early 1942. If you have the rubber mounts I would support part of the weight when changing the rails. I think its a good practice on the solid type. Even if its not a have to thing.

I've got 80psi on every cyl. I thought that is a little low. If it has a distl. head should'nt that explain??

Yes you have a distiliate head. Same as mine and yes the engines are rubber mounted. I did put a jack under my hydraulic pump but thats all when I changed mine and really the only reason it was under there was I had to split the tractor to get a bolt I dropped in the starter hole out. Make sure if you change it to new rails you get new style engine mounts for it. Lots of old war model tractors around with busted frames. Mine is a 1942 but its a early 1942. Any more questions feel free to ask.

Good Luck

Do you have to/should you support the engine when you are splitting a tractor at the clutch and bolted to the frame rails? I was a little suprised to see my MD sag that much. I jacked the engine up and put some bolts in there during the clutch job, etc.

When removing the bolts for the split, unscrew them but leave them in the holes. That way they can support the rear of the engine.
