Super C hydraulic pump flow and pressure

I posted this in the Farmall forum, but I figured I might get some more responses here.

I am designing a hydraulic winch to use on my Super C. I am trying to calculate the RPM of the hydraulic motor I am going to buy for the winch, but I do not know what the flow rate or pressure of the Super C hydraulic pump is. Also, how is the pump powered? If the engine RPM is 2200, is the pump being driven at 2200 rpm?

My Super C is a 1952 model. Based on what people have said and what I have read, the hydraulic pump is probably around 1000-1250 PSI and 4-5 gpm.

However, I read that there is some service manual that lists the exact size of the hyraulic pump with exact specs, like flow rate, pressure, and what RPM the pump runs at.[/list]
 
Back up and rethink your project. You have two good choices direct drive the winch off the pto or drive a PTO pump with tank setup. I can send you some photos but not having 3 point hitch you are going to have to design a quick mount there on the rear some way. What ever you build you actually need a blade to stick in the ground to do much winching. That supper C will just slide pretty easy. I think you figures for the tractor are about right and just not enough from the tractor pump to do much winching . Wish you were closer, I have all kind of winches , pumps and drives.
 
O K you are so good on these projects I am going to help you. Thing is it is dark and pouring down rain right now but in the morning check this post and I will send you the following photos, hydraulic winch I built, a typical pto driven pump, a photo of a direct drive winch and some smaller winches I have. May be noon but be sure and check back. Just a a point what is it you think you want to be able to pull or winch, so I will know how big a unit we want to build. Like you young interest and sure am glad you settled on the C instead of the H , think you will be better off.

JM thank you so much for offering to help! I am looking forward to seeing your pictures!

I am making a winch to drag logs out of the woods, and also to do other little stuff like ripping out brush.

The only reason I was thinking to use the stock hydraulic pump already on the Super C is that, based on my calculations, it will give me more than enough flow to gear down a hydraulic motor for a winch. I just would hate to spend $300 on a PTO pump if I already have enough flow with the pump already on my Super C
 

It is actually already 12 volt. The thing is, I want a project and I think it would be a fun project to build a hydraulic winch.
 
I think the hydraulic or pto winch is the way to go. A couple of my friends have hydraulic winches on their jeeps driven off of their power steering pump. You can pretty much winch all day as long as the motor is running. I have an electric winch on my PU and it pulls good but really zaps the battery
 
I think the numbers you have are probably close enough. Certainly your existing system will perform better than the power steering pump mentioned above. You just need to select the right motor and go from there. I had always dreamed of doing something like that and had collected a few motors but never hooked any up.

The only actual experience I have had with a hydraulic motor was a large auger. I ran it with various systems large and small, it performed well just ran slower off a small pump.

It is not rocket science, you could match up pipe sizes and go for it.

Looks simple and effective.
Winch

Steve that looks very nice. I was planning on going with a steel cable, however, I will take that into consideration.

Through some research I did online, I found that the Super C hydraulic pump is most likely 0.37 Cubic inches per Revolution. Then, I found that the hydraulic pump RPM is related to the crankshaft RPM by a ratio of 33/16, or roughly 2 to 1.

Knowing that the maximum Super C RPM is around 1650, I can calculate the maximum flow rate of the pump, doing 1650 x 2, then using a hydraulic calculatator to find flow rate.

My question is, if the Super C will fun at 1650 rpm with wide open throttle, what is the lowest RPM the Super C will run at? In other words, if I put the throttle all the way down, or only advance it one fourth, what will the approximate engine RPM be? I had trouble finding that simple information online.
