656 Farmall Hydraulics

Bobby Hinson has a question just below you with his 2656. Don't know the answer to your question.
I would get a good service manual to see if it's covered in there. Your local Case/IH dealer may be able to zerox that for you. Call 1-800-732-0017 and ask for farm tractor service. They have 4 dealerships and are pretty good about doing this. Hal
 
Comon' now Pard, you're not thinking this through.

How much gratification did that new front pump replacement give you as far as the 3-point operation goes? By your own admission, none. Zero, Nada.

Therefore……………………………

Your local IH mechanic probably means well, but he is just flat out mistaken on how that system operates.

Take the seat off the tractor. Remove the square plate above the three-point galley.

Then, without a load on your weak hitch, operate the hitch up and down a couple of times. It should move smoothly thru the up and down cycle, albeit slowly perhaps?

"IF" you see no "boiling" oil in that galley during hitch operation indicating a possible massive piston seal leak, o-ring leak or cracked cylinder, replace the REAR (piggyback) pump.

Yes, the one that is called the “hitch” pump.

They wear out and their first symptom is weak load lifting capacity. Second symptom is the hitch won't even move.

Yeah,

It's too darned bad that you were given the wrong info. Good news is that you are gonna have one heck of a nice tractor when all is said and done.

Don't know why folks have such a time with the "small frame/large frame" thing.

Square axle housings or 6-sided; all of those old farmalls fall into one category or the other.

Good luck with your repair,

Allan
