Got more questions, this time about my M's char-lynn P.S.

Patrick HMD · Sep 15, 2012

I've been busy fixing 'things' and tying up loose ends on my M. And there are a lot of them. One of the major ones is the char-lynn power steering unit. I'm finally getting round tu-it. Yea, another trip into the unknown. I guess that says it all, because I don't know squat about power steering units. The prior owner removed the belt from the pump, and one of the feed hoses. Here's what I have at the torque motor.

As you can see, there is a valve stem from a tubeless tire rim screwed in at the port end. What's up with that??!! The bottom hose goes back to the reseviour. So I assume the missing top hose goes to the pump, Right?

Now you can see what I have at the pump end. A drain cock!! Once again, what's up with that!!??

I'd like to get it hooked up and running again, just to see if it works, and also see if there are any leaks.

So what's with those weird fitting on those port ends? Apparently the prior owner disabled the unit for reasons unknown, and I'd like to find out why.

My guess is that the previous owner May have blown a hose and then plugged the ports to keep dirt out. Get a new hose and when you start it up, run it slowly and check for leaks. You might get lucky and it is just a case of a person needing the tractor and not having the time to get a new hose.

That was my guess too SDE. Thanks

Go it all done today. Tomorrow I'll put some oil in the rez. and see what I've got. I'm keeping my fingers crossed. The top inlet hole on the motor was 3/8" npt. No problem there. The inlet hole on the pump looked the same but was not! Close, but no cigar. The 3/8 npt barbed end fitting would not screw in. After doing some checking, I ended using a 5/8" NF thread chaser on the 3/8 npt, and seemed to do the trick.

barbed fittings? They're gonna blow right off under pressure, no matter how tight you crank down the hose clamp.

Yeah, that got my attention too. I imagine what you had in the pump was a JIC fitting and not a pipe thread... hope you don't have a leak there. You will need a hose that will take at least 1000 to 1200 psi and I don't know of a barbed fitting and hose that will do that. I see your pump has a relief valve built into it and it may have the set pressure stamped on it... you will need a hose to handle that.

WOW!! Little did I know! I'm such a jacka$$. [but I'm learning] Thanks guys for steering me in the right direction. I'm sure the whole content of the oil reseviour would have been all over the shop floor had I cranked up the engine. What a mess that would have been. I'm thinking about going to the IH dealer or NAPA store and see if they can fix me up. Some things are best left done by the pros, and I ain't no pro.

Well, here I go again. I'm not going to let this one die just yet. I was advised not to use barbed fittings and hose clamps on the hose ends because of high pressures exerted by the pump. And I understand that perfectly. But look at this picture of the hose end connection to the reseviour. It looks to me like that is what we have here.

Now look at the opposite end on the outlet side of the motor. Same thing. Now I'm assuming that both of those connections have barbed ends due to those hose clamps which are clearly visable. Am I assuming correctly? I'm a bit confused. Anyone care to comment on this? Please forgive me if it looks like I'm trying to stir something up. Not at all. I just want to get my head straight on this.

There is a low pressure side and a high pressure side. You can usually get away with barbed fittings and hose clamps on the low pressure side I guess. It's not ideal, and usually better to do it right the first time.

Patrick HMD · Sep 19, 2012

Low pressure side, high pressure side, ahh ha! Bit by bit, inch by inch, I'm learning all this stuff. I'm not going to learn unless I ask. I'm more at ease now, I can let it go. I'm thinking maybe the hose blew because of it not being treated as a high pressure hose. Just no way of knowing. Thanks mkirsch.

Wow! Surprise, surprise, I've got power steering! Took the pump to a pro, and he fixed me right up. $30 he charged me for the hose. I was a bit leary when I first saw the unit on the M. With the missing hose and belt, I thought for sure that the unit was trashed out, and was thinking of removing it. Glad I dismissed that thought, because now it works like a charm.

Well as the old saying goes: 'Never judge a book by it's cover.' If you've seen the pictures above, you'll know what I mean.

Excellent. Just give those hose clamps a check once or twice a year and you should be ok.

Running into one of these units on a Super M. Has a pump with the reservoir right on the pump. They come off a 63 or 64 Ford Galaxie. I"m wondering the filter number inside the reservoir. Taken these apart before, take the lid off, then a spring and washers to hold tension on the filter, then the small filter comes out. But can"t seem to find someone who knows what the filter number is? Mine is missing completely. Thanks

ilter, what filter? That's news to me. There's no filter in mine. Anyone else like to comment on this? Now you got me wondering cp1. I thought I was done with that ps.

Patrick, your's doesn't have that pump with the can reservoir like the Ford pump.
Have you tried your local Ford dealer? If they don't know squat, try calling Schmidt's Haven Automotive in Haven Ks. Used to be a Ford dealer and have a huge stock of NOS parts... ask for John... 800-748-7803. For years any time one of the old small town dealers went out of business, John bought up their parts stock.

D Slater · Oct 29, 2012

Need to look to be sure but think the NAPA filter 1653 is the one for that.

Peter Glasgow · Oct 29, 2012

As D Slater stated, NAPA filter 1653 is correct and readily available.
