Farmall H Kero vs Gas head rocker arms

Goodmorning everyone,
I am going to put a kerosene head onto my H (had a gas conv. on it). I was wondering, do I need to get longer push rods and the rocker arms for this head too? Are the rocker arms and pushrods the same for gas and kero?
Thanks,
Ryan

Just curious here. I priced a 5-gallon pail of kerosine at Ace Hdwr 10 years ago and it was $52. That was way
before the latest end-run theft by the oil companies. Considering the huge fuel cost and low HP on KD, what's your
goal? :) gm
 
I think it is just the valves (length of
valve stems) that is different.

The valves are a different length, to make
up the difference in the variable recessed
dome between the two heads. The higher the
recessed dome is, the shorter the valve
stems needed to be to compensate for this.

IHC didn't like making any extra parts than
they had to. So I am quite sure, they made
up for this adjustment, only with the
valves.
 
You did not read what I wrote in that other post very
well. I said this ..The depth of that chamber is what
changes the length of the valves because the rocker
arms and shaft set at the same distance from the
surface of the block no matter what fuel the tractor
was designed to burn.. I maybe should have said they
set the same distance from the head to block mating
surface. If the shaft and rocker arms are the same
distance from the cam and lifters the length of the
push rods are the same. I suppose you can not surmise
that directly, but it is the case. Any comments about
your enlightenment about the proposed valve swap in
that other post? We put a lot of info there and not a
peep from you. Are you a fairly youthful person?
Seems to be the style these days, minimal gratitude.
Sorry, maybe I am calling you all wrong. That is a
general statement, nothing against you directly.
Previous post on Farmall H Gas Head w/ Kero Valves
 
This guy has posted numerous posts. Don't think I have even read em all.

He evidently thinks this tractor has GOT to go back to a kerosene burner. Even though it had been converted to burn gas, with a gas replacement head.

I don't think he has researched out the price and availability of kerosene. Nor realizes that NOBODY tries to burn kero in H's anymore. And 99.9 percent of the people that have a kerosene burning H, just burns gas in them 100 percent of the time. And the other .1 percent, only burn a little kero for a demonstration purpose at a tractor show.

He's had a lot of twists and turns in his efforts. And other suggestions thrown to him along the way. And is still bound and determined to rebuild it as a kero burner for some reason.

Puzzling to me too!! I just answer his questions if I can, and move on. I have a kerosene burning H. I burn gas in mine all the time. 100 percent. I wish I had the gas pistons and head on mine. I'm though suggesting this, to this guy. His mind seems to be set on kero.

I guess he'll find out, when he gets it done.
 
Thank you everyone for the support. Kerosene at 7/11 is $4.20 which is $0.40 [b:63cdcfe3ca]LESS[/b:63cdcfe3ca] than regular gas prices. I don't mind putting a little bit more money for fuel of a tractor if it's perfectly restored (IF it was more than gas!). Not many of them run on kerosene anymore and it would be great for show. I'm not using it as a main tractor on a farm, so it doesn't need as much horsepower as I can get out of it, otherwise I would have went with a more powerful tractor! I can run it on gas if the price of kerosene skyrockets, but I know my area better than you guys. I understand that I may want to convert it back to gas for "less hassle" and "less money" but I can always keep the gas head and exchange the pistons. I am using it as a project and I enjoy the labor of it.
 
I am surprised you can get it at a 7/11,
and at that price.

Just out of curiosity. You said you have
everything else required to burn kero. Do
you have the right manifold, and is it
functional??? A kero burner requires a
manifold that channels the exhaust around
the intake tubes, to preheat the intake air
before it enters the head. There is a
mechanical flapper inside that will direct
exhaust around the intake, or directly out
the upper manifold when burning gas. These
are notorious for seizing up (rusting
solid), so it can't be manuevered anymore.
It's near impossible to find a used kero
manifold that is still functional. Not sure
what the situation is, on finding an
aftermarket one. Guessing higher than heck,
even if you can find one.

That is probably a bigger damper on people
trying to do what you are doing, than the
situation with the head and pistons.

You do realize that to burn kero, tractor
has to be warmed up on gas, to near hot, to
make the switch to kero? And then on shut
down, it has to be switched back to gas,
and let run long enough, that gas is what
is in the carburetor. If not, the tractor
won't start when cold, with kero in the
carb.
Not that big a deal if running the tractor
all day. But to just putter around, never
running the tractor very long at a time, it
is pointless to mess around with that
hassel. Kind of senseless to make the kero
switch, when if otherwise, you'd already be
shutting the tractor off.
 
Guys,maybe Ryan works at a big airport refueling area and has access to all kinds of jet fuel. :lol: :lol:
 
Yes, I have all of the kerosene components. Functional kerosene vaporization manifold, heat shield, kerosene carburetor (drain), aux. tank.
 
I'm guessing not. And even if it could kind of be done, tractor would run pretty poorly.

Retarding the spark would not help.

I tried to duplicate distillate one time (because you can't find it anymore), by mixing gas and diesel together. My experience was, the gas and diesel would separate back out, with gas coming to the top. You could see it happen right in the sediment bowl, from straight gas coming from the reserve tank. I would wonder if you wouldn't have a similar affect with kerosene.
 
(quoted from post at 15:51:43 05/19/22) Will it run on kerosene as is?

No, I guess someone rebuilt the motor at some point and installed a replacement gas head. All of the kerosene / distillate parts were left on it though.
 
(quoted from post at 13:47:44 05/19/22) Kerosene at 7/11 is $4.20

I am able to get kerosene at a 7/11 pump for $4.20 / gal.

My bet is they sell very little of it and that $4.20/gl price is based on what they paid for it five plus years ago or more.
And when gone, the pump and tank are going bye bye.
