Char Lynn PTO pump manual ??????

eye owa · Nov 29, 2010

I recently acquired a Char Lynn PTO pump/reservoir unit. The pump is enclosed inside an aluminum reservoir. There are two splined control shafts at the end of the reservoir near the PTO connection. The pump/pumps inside look to be a single-action and a double-action pump side-by-side with connections. I would like (need) to know the intended purpose of the connections and controls.
If anyone has a manual or illustration for this unit, or even experience with such a pump, I would like to get in touch with you. Through this site I have learned what exactly I have in my hands, now I need to learn how to use it or adapt it for crankshaft connection, if possible. I think the unit is called a Hy-Lo power pac. There are no numbers anywhere on the unit. I get no response from Eaton who took over Char Lynn years ago. This is probably too old for them to have manuals, parts, or to even care! I will continue to check this tjread, or my email is digiterry at netscape dot net. Make the obvious and appropriate changes in symbols.

Thanks much, Terry in Iowa

It was used on tractors that didn't have factory hydraulics to raise a plow or loader. I had one on a 1937 John Deere A to raise the loader.

I have a couple of Char-Lynn manuals, but I don't think they are for the equipment you have. The manuals I have are for power steeering units. Would these be of help to you?

Forget about a crankshaft connection as any engine would be running fast enough to tear up that pump as the limit for that phmp would be 600 MAX RPM and your engine crank could be turning at up to 3,000 RPM depending on model of tractor. Then the handles have to be where you can reach them, DO YOU HAVE 10' long arms to reach over the hood of the tractor? To try to make linkage to operate would be a nightmare. They were not even practable for the Ford or Ferguson tractors as you did not set over the PTO shaft as you did on the A C, J D, IHC, MM, Case, Oliver, Coop, Cockshutt and Avery tractors as from those tractors you could reach the controls easy from the seat. If you do not want to use it as designed sell it to someone that will and if you want a crank pump buy the correct setup. That was designed for use on a tractor that did not have a built in hydrolic system so you could use say a hydrolic loader with a cylinder dump bucket ar like pulling a wheel disk and a hydrolic lift grain drill in tandem.

The one that i have was on a loader with single acting hydrolics and only lifted the loader.The bucket was a manuel trip.When i tried to use it years later oil came out all the seals and orings.Its allso a 1000 pound low preasure system and would not work on newer stuff.

Leroy,
Thanks for the input. Since I don't know the capabilities of the pump, connections, and controls, I'm trying to find out! My thought was to, if possible, lock the pump into a flow position and route the flow through a two-way spool within comfortable reach . Once again, I was unaware of the RPM limitations. I am a "can-do", or at least "will-try" kind of person who loves a challenge! I would be more than happy to sell it to, or trade to someone who could use it and had something that would work for what I want to do, which is operate a FEL on a 9N. Seriously, thanks for the reply.

Is any of these what you have??? I found this old ad.

I have ran a FEL on a 1944 model 2N Ford for years, Basicaly the same as a 9N with just a couple of changes due to the war. The built in pump handled it easly, plumed in a control valve for positive control and return oil was thru an adapter that screwed into a bolt hole on the side plate and oil was taken off what some call a test port on the right rear of the hydrolic pump. Had to hold the lift arms down slightly tho and down 2" is enough, had brackets made to fit around the axle tight and with a bolt thru the top where the pin is normally between the rockshaft lift arm and the lift rod for the arms are. With that setup had insteanious hydrolicks instead of delayed action like using a chain to hold down the arms as some do will have. We do have a solid transmission-differential mount hitch on the tractor so did not need the 3 point for pulling. Had the exact same setup on a Ferguson 30 that the Ferguson dealer put on so copied it for the Ford.

Leroy · Nov 30, 2010

Few more thoughts, if you want to be able to use the 3 point at the same time put it on the pto where it was made for and then using some rod, same size as curent levers and route then up to where you can reach them from the seat and use two cable clamps to fasten them to the levers. The extra distance you will need that way will make you move the lever about twice the distance the normal lever moved to work. this would let you use a power dump bucket where the setup I had was just a trip bucket but by adding a second valve in line could have used a power dump bucket. You just get so used to the shifting you do not give it a second thought.

here is a pic of the pump mounted on my w-9. the splined shaft is what your control rod hooks to to operate the pump. the rod should go thru the pump so you can hook up to either side. if you look just below the seat to the right you can see a black knob on the control rod for my pump. this is a two way. it has two output hoses to run a 2 way cylinder and get down pressure. i also have a one way pump in the barn. adding a two way valve in the output and returning to the resevoir fill hole will get two way if you wire the control in the full on position. i run hy-tran in the resevoir.

would you please post a couple of closeup's of the mount between the tractor and the Char Lynn unit

Thanks
Ron

glennster · Nov 30, 2010

i'll get a few pics this weekend of the way the pump mounts and post em for you.

evilboweivel · Dec 1, 2010

thanks

I have a pump, complete with coupler, will snap a picture when I out to where it is.

I MAY have a manual, in my late Uncle's desk drawer, used to be there, I'll take a look for that also.

For now, here's an ad from "back in the day":
