Farmall Power Steering

Hey guys! Think I have decided to put whatever loader I buy on my SH as it already has a live pump on it... With the loader, I am also thinking about some power steering. I came across a Charlynn kit off an M at a great price so I bought it. It is missing the pump pulley and mounting bracket for the side of the governor. Now, the only mounting brackets I can find for the side of the governor are listing M and SM but not H or SH for fitment. Questions:

Will that mounting bracket bolt up to the SH even though it is not listed?

Will the pump and resvervoir fit my SH as it did the M its coming off of (cutting a hole in my hood is not an option)?

What size pulley do I need for the pump? ...I am thinking they were 5"

Lastly, the only power steering I have previously added was on a 400 and I used the saginaw pump mounted up high...other that cutting the fan shroud and having the crank pulley, do I need anything else that I would not have used before?

***Picture is of a kit off a random M but is the exact same as what I have.

Thanks!!!

Look at your SH. See that lower radiator hose? Right smack in the way, so this isn't going to work.

Use the torque motor and a priority valve to hook into your live hydraulics.

Using your tractor's live pump with a priority flow divider will work if you add a pump for your loader.... live pump will not supply both. I'd use the Saginaw PS pump and mount it higher under the hood... I think I have recently seen pictures on here showing that set-up. You will need to fabricate a bracket for the pump.

Ah crap I forgot about the radiator hose on that side of the SH! Any loss of steering power or loader power with the priority valve like that? Not sure which pump I have or how good it is...

Allan in NE · Jan 10, 2012

Hmmmm,

Guess my tractor didn't get the memo.

Been running a loader and power steering off the live pump for about 10 years now (took some fine tuning on the priority valve to get it just right).

Will agree tho, it's not a fast as a PTO pump, but then, neither would the live pump be by itself either.

The torque converter off the M will not fit under the H hood. And the two I have on an M and a SM had the hood bent to fit over it. It can be made to fit properly on the M, I doubt it will fit the H.

mkirsch · Jan 10, 2012

If you had to bend the hood, you didn't do something right.

The Charlynn torque motor will fit under the hood of an M with no modifications.

The steering "hump" on an H hood is the same size and shape as an M, because it has to make the same clearance for the same size steering shaft.

IAtractorKid · Jan 10, 2012

I dont think the saginaw pump will fit under the SH hood without cutting a hole as seen here (although that looks like an Eaton pump to me). Cutting that hole for the reservoir is not something I want to do...

CNKS · Jan 10, 2012

I'm not not the one that installed it -- I still say that a Charlyn will not fit -- until someone shows me a picture of one. I do have charlyn on a 350, the different sheet metal allows it to fit, barely -- but the location needs to be slightly changed.

Wardner · Jan 10, 2012

CNKS,

Just so that others don't have to scratch their heads too much, "torque converter" should be "torque generator". I know you know the difference and were probably searching for the word while typing.

Allan in NE · Jan 10, 2012

Here ya go.

First picture is of my M and the second picture of my H.

Both running happily out on my farm. Yes, both with the hoods on. :>)

On an H you have to buy the wedge adaptor and redrill the alignment holes to "cock" the motor in the right direction.

Ok, I will withdraw my comments. But even on the SM I currently have apart, I had to get a different hood, and will make the PS fit right. Previous owners used a hammer to make the hood fit, and also the one on my M. The one on the 350 I bought last summer barely fits, and will have to be modified some, when I get to working on it.

Allan, will any priority valve work for this application or do I need something specific? I actually have one out in the shop...

Prince RD-575
30 GPM Max Input
3000 PSI
2-12 GPM Adjustable Priority
3/4" NPT

I would think that would work right??? Have I read somewhere the Charlynn takes 3 GPM or something like that? Thanks!!!

I'd think 2.5gpm will do. I don't know how much larger the live pump is on a SH than my 240U, but my 3 point will not operate when the engine is idled down due to the CharLynn steering using the flow. I do not lose steering, but the 3 point will not operate below about 1/3 throttle. My loader has a separate pump in front off the crankshaft. I would not use a PTO pump as it will not be live. From the looks of the plumbing on mine, the loader at one time used the live pump and tractor valves, but my guess is when the PS and pfdv was added, they also added the front pump and a set of valves mounted on the loader. Your SH may have a bigger pump than the 240, but it better be a lot bigger if it's to work both, especially when idled down a little.

I ordered a 5 inch pulley from Force America last fall.I think it may have been around 20 bucks. I think their part number was 20926. 1-888-99FORCE

IAtractorKid · Jan 10, 2012

I"ll try and get some pictures of the SH pump and maybe someone on here can ID it. I dont remember there being any markings on it but I have not looked real closely at it for a few years and it is currently an hour away.

Would you by chance have any pictures of your front mounted live hydraulic pump? Maybe I could rig something up like that as well...

Don't do pictures yet, but I doubt the pics from a 240U would do much good. Mine has the pump bracket built off the loader bracket which "wraps around" the front of the tractor, and a shaft goes through the hand crank hole. This pump mounts with bolts to the base of the pump and not the front plate.
If I remember right, the hand crank hole on the H/M series goes through the front bolster at a slight angle??? If that's correct, it would not work very well to drive a pump.
Wardner has some good ideas using an AC clutch on the pump, but if you have 6V, that may not be easy to do.

Janicholson · Jan 10, 2012

A Honda Civic PS pump has a remote reservoir and is well built and can be placed easily. Jim

CNKS · Jan 10, 2012

Yes, you are correct.

Does not require fan shroud modification

This is a $500+ clutch pump but you don't the electric clutch. Crankshaft pulley is 7" but would be easier to fit with 6". Pump pulley is 6" but could be smaller without the electric clutch. Two belts for high loading and long life.

Others have used roller chain and placed the pump on the top of the right side frame channel. I call that a safety hazard and a maintenance headache.

GordoSD · Jan 10, 2012

The 1953 Charlyn Kit instructions had several paragraphs and a template for "reshaping the area" over the TG for a proper fit.
But ask yourelf, do I need the aggravation, expense and trouble to have PS on a tractor that almost steers itself? If you are moving/rolling 4-500 round bales in a day then maybe.

2+2 Guy · Jan 13, 2012

I'm curious about the "wedge" inbetween the mounting plate and the torque generator that I see in Alan In Ne's pic. Was this "Wedge" something that Charlynn supplied or was this custom made? When I mounted the PS on my 46M I bought a gauge mounting plate off ebay that was suposedly specially made for the Charlynn unit. It was not an OEM piece but something that someone is custom fabricating. It was a nice piece and fairly well made but I still had to do a little bending to make the shafts line up and use a die grinder to make the holes fit the gauges. Would this "wedge" that I see in this pic allow you to use the orginal gauge mounting plate?
The reason I'm asking is that I would like to put P.S. on my 51M this winter.
Thanks for any advice,
John
