Farmall H power steering setups

ryanwheelock · Jan 26, 2011

What would you guys say is the best power steering set-up that can be added to the Farmall H. I know theres a Behlen pump and a Charlynn if i rememer from older posts, any others?? Are they both the type that u cut the steering shaft above gas tank and install it there. Do you need 2-way hydraulics if i remember right, which I have installed already. Just researching it and want to know the diff. types and styles and pros and cons before I buy anything. Any input and or photos would really help.
Just wanted to add I changed the tractor to a wide front, added a loader, 2-way hydraulics, M&W hand clutch (just started to install it this week). Dont really need power steering for my play toy but would like to add it someday down the road.
Thanks guys

Keep all the snowplowin and snowblowin pictures coming, love to see the plowing rigs!!!

CharLynn for sure; just plain looks better because it is hid.

I've got one of each. That is, one using the hydraulic live pump and the other uses a dedicated PS pump.

Gotta recommend the dedicated PS pump, because with the live pump, you have to use a priority valve and it "robs" from the pump's output.

This really makes a difference when using a loader or a torque motor off that main system.

There are three popular options for power steering on a H or M. Charlyn or Behlen, and hydrostatic system (commercial kits, or retro from a combine or other system.) The hydrostatic system consists of a steering wheel driven pump that supplies pressure to a cylinder on the linkage or bolster that amplifies the fluid pressure to assist the steering action. There is no connection between the wheel and linkage. This last method is common on more modern (1960s+) tractors and combines. power steering supply is usually one pressure hose and one return. The supply is thus open center one way (to the steering at least). Supply from on board hydraulics must be live, and must use a priority valve if the pump is used for any other hydraulic application and the steering. Many add on systems use a separate pump for pressure (belt driven is common) from a medium duty truck or some passenger cars. Eithe of the two brands mentioned (if used) could need a seal kit, but both seem reliable. Jim

Besides whats already posted some of the charr lynn kits on a H used a pump driven from the generator belt and required a hole cut in the top of hood. Something else to consider with type used.
From a mechanical veiw point I like the torque generator mounted in the rear steering shaft. More support for the worm shaft, less woble. If a charr lynn type is mounted to a solid mount under the hood a flex joint is used that is not ideal in my opinion. Some use a solid coupling to the charr lynn under the hood, but then the worm gear forward and rearward torque is transfered to the torque generator. Even with a new bearing on the worm shaft there's a little movement.
When the torque generator is mounted in the rear steering shaft you can use solid keyed couplings and the forward and rear movement is absorbed by the flexable mount and steering shaft sliding in the rear shaft support.
From a tractor looks standpoint I think under the hood looks the best. Just my opinion right or wrong.

I agree with Allen on the dedicated PS pump. Dad had a Char-Lynn on a JD 60 and I have one on my 240U. Dad's had a belt driven GM (Saginaw) pump and mine uses a flow divider.... Dad's was much better as the fluid "robbed" from the tractor hydraulic pump slows down the 3 point... actually stops it when idled down because there is not sufficient flow. Dad's hydraulics and PS on the 60 always worked.

I get a kick out of those who want to hide the actuator under the hood (because it's ugly?) but think nothing about destroying their fan shroud. To each his own, I guess

It is quite possible to run a PS pump without cutting anything. There is the governor mount, high mount, and low mount. The last one requires no sheet metal destruction. The same might be said for the high mount but I have never tried it. The governor mount is the easiest and is suitable for those who don't give a damn.

I like the suprise factor of having a secret PS system.

I think I said it last time PS came up, but everytime I run my MD I can't believe the difference. I usally crank the wheel way too much bc I am used to a little resistance.

It is amazing that people will pay over $600 for a PS pump that really isn't needed for anything more than cool points. Then they want to hide it away and not let anybody know they have gained the cool points. It is like having a brand new pickup in the garage, but you drive your dirty old farm truck to church.

Some of us use tractors for farm work; imagine that.

Grab a forkfull of a 1500 lb bale someday and maybe you'd understand the convenience of power steering.

Why don't ya put up a picture of your tractor and I'll return the favor.

What kind of pump is that?

Then you are probably not going to worry too much about the exact location of your actuator or if you have to cut the fan shroud or notch the hood to make PS happen.

i didnt hide my power steering on my 48, i just leave the hood off!!! loader is an american road off a 560, bucket is off a john deere backhoe/loader combo. air ride seat is off i dunno what. live pump, belly pump, hoses everywhere. did a pretty good job lifting a dead 254 off the trailer!! oh yeah, hit a tree limb with the muffler too. this old gal has been rode hard and put away wet. still a hard worker.
