Jerry-
Here are a couple scans from the manual for a Johnson loader that should give you some of the information you were asking about..

 

[aaytay]

Here it shows you that they used a 2" diameter lift cylinder...

Jerry-
Here are the specs from a later Johnson #10TC...

my loader has a 4 to 8 gallon a minute pump that I got from Northern Tool item 10567 and I ran a belt off my PTO so I could disconnect (shut off)the pump when not needed

I never had an issue with the pump and works great on my loader. I have noticed because of the large cylinder size I have to run a 2500 rpm if I want to lift and curl the bucket at the same time.
I could have used a smaller cylinder size. I have not set the pressure down on the control valve so I think its still 1200 lbs. I have a snowblower to deliver and will post later If you need more info. later Don T


Ken I did try lol

I have to redo the hydraulic lines to install the hood and grill but i`am to busy now.this works great and has moved more the 24th lbs of soil and rock since I painted it. Later Don T

Art, it's interesting that the original Johnson ran at 400 psi and the later ran at 1150 psi but nothingelse appears to have changed much, although cylinder bore isn't listed. Wonder if the 400 is a misprint.

Don, does that pump have the actual manufacturer and part number on it? The thing I've found is that 99% of those pumps don't have an adequate bearing or bushing on the input shaft to handle the radial load of a belt, chain, or gear drive. They're designed to be coupled with a Lovejoy or similar coupling to a shaft mounted in line with the pump. The only company I've found so far that makes a pump rated for radial loading is Marzocchi. I have a quote coming on it.

John,

My uncle still has 250 acres of corn standing...for his sake no snow...this wind will be bad enough!!!!! They pulled the bottom seive out of the combine yesterday because the snow on the corn kept freezing it up.....YUCK!!!!

Loaders,

Arts info seems to be about std for GT loaders of all brands, somewhere around 1200-1500# pressure.

 

[aaytay]

Jerry-
I thought the same thing about the different PSIs listed. I've always thought that #1,000 was right around where you want to be for a GT-sized loader.

I had the same pump on an OFF-TOPIC tractor that Don showed. It worked well, and was mounted using a pulley and belt to drive it. I didn't keep that tractor long, so I don't know if the pump was able to handle the side-load or not. (I didn't know about side-load issues with pumps until later.)

Jerry Muncie
that pump will run your loader and since it was designed to run on off a PTO and has the front bearing to handle that stress and the price was right Only $139.99
here is some more info from the pump.
Haldex High Pressure Hydraulic Gear Pump .517 Cu. In., Model# 10567

Use it on mobile equipment, construction and agricultural equipment, machine tools, material handling and mining equipment, PTO pumps, refuse haulers, compaction and baling equipment. Standard 4-bolt mount. 1.78in. diameter pilot with 1/2in. x 1 1/2in. shaft, 1/8in. square key. Heavy-duty cast iron pump turns at 4000 RPM max. in CW or CCW direction. Use as a fluid pump or fluid motor. Similar to Parker D Series, Webster YB Series, Rexroth S12, MTED Series. Flexible coupling or belt (pulley) drive. 95% efficient. U.S.A.

here are a few more specs that you will need to consider.

Additional Specs

* Cubic Inch Size: .517
* Flow at 1800 RPM: 4.0 GPM
* Flow at 3600 RPM: 8.0 GPM
* Maximum PSI Cont.: 1200
* Maximum PSI Intmt.: 2000
* O-Ring Port Size, SAE: 7/8in.-14

I did a lot of looking for a pump to run on my loader and well this was in my price range and had all the features that I thought I would need to run my loader. Good Luck later Don T

Dennis, the TV says Madison has about 17" on the ground and parts in my area has 15". I would guess that I have about 12" on the ground where I live. I know that it looks like the 106 with blade will be used mainly for clean-up and the M with v-plow will get the blunt of the work. I have to go get my step-daughter from the hospital this morning so I will find out how bad the roads are.

I always use pump belts with the least tension I can get away with as belt replacement is cheaper than pump replacement $$$. so If my belt makes a squawk when turn on the pump i`am happy. Most pumps are damaged by the owner because of belt tension. way to tight is the norm. I found a lot of pumps out there in the market ,but not many were CCW and would work in the rpm range a Cub will produce with a max of 3600rpm. Let us know what you will use and the price and spec please. later Don T

Art: Methinks that crank and assorted Stens stuff's going into a Kohler, then into a Greenie?? ļ

 

[jdelles]

i was on e bay the other day looking at parts that i need and came across a guy with a machine shop that rebuilds the hydro check valves for $35 each.there was no phone # or address though but his e bay ad runs regularly.just thought i would pass this on as they are big money. thanks jim

Hi WES. I heard the news say 17-18 in. but I sure don't see that deep of snow around here.

With the wet snow and the wind picking up We've got some evergreen tree damage. Hopefully the power stays on.

I got the chains & blade on the Super H yesterday aft....Guess I better get out and play before it gets much colder. Supposed to be 20-30 MPH winds and Zero tonight! Whatever I move will need to be moved again. Sure wish I had a cab or heat-houser on the SH. Brrrrrr!

 

[mhomrighausen]

Let's see how these turnout. I went out for not over seven minutes and took these with my cell phone about an hour ago. I'm on dialup with the laptop. The wind made my hands turn white in almost no time. The town is trying to clear the streets with a big CASE endloader from the local implement dealer. The drift in front of the garage is over two feet deep. The neighbor's van is alongside a drift almost as tall as the van.

front of garage. I just pointed and clicked then saved. My fingers were COLD.

east of house. The endloader made one sweep past our vehicles. That is the neighbor's van and a skidloader in the background.

Neighbor to the south of us yard. That is blowing in the yard.

front of house. The town had a diesel pickup parked at the end of our drive.

The wind is causing the furnace to kick off and on. When things finally calm down the 125 and Keepsake 1650 are going to have all they can do to clear the area. This is truly one time that I wish that I had a full size tractor with cab and loader.

 

[jott]

Dennis f, where do you live? We currently have 12 to 13 inches and are expecting to get another 3 or 4 later. THEN, The best part about all of this (pun intended) is that there will be up to 50 mph winds. The snow is suppose to be wet, but i havnt ventured outside yet. I dont figure I will get too far with a 12HP tractors and a 42" blade, but who knows.

Lonny B, you know what we are going through in Wiscosin, dont ya!

"Killer", the K301 in my #2 125 fired right up this morning.

I sure do like the way it starts, not sure if it's David Kirk's awesome rebuild or the points saver and Bosch Blue coil, probably both.

I already have my driveway cleared out. We only got about 6 or 7" so far but it's still coming down a little. It sure is blowing around. I think the PTO might be slipping again

because I had to go slow in some areas or it would plug up. With the Slip-Plate it's easy to unplug, just lift and drop the snowthrower and it clears right out. The belt is nice and tight so I don't think it's the belt slipping. Oh well, I'm getting good at removing the PTO.

Richard C., no need to post about the advantages of an electric PTO...

 

[jmuncie]

Well, my hydraulic rep just e-mailed me. The Marzocchi pump I wanted was a catalog item for them, but it's still a special run. Marzocchi is not interested in producing it in small quantities.

However, he found out that Parker does have something and he's looking into it. Don, based on your info, I'd expect it to be the Parker D-series. Good news is that I sometimes get OEM pricing no Parker, so I may be able to get into it for the same price as the pump from Northern. As soon as I get a chance, I'll dig up specs on that pump direct from Haldex.

Thanks for the info,
Jerry

Jerry, if you'd like me to I can check tonight to see if there's a manufacturer's label with a part number on the pump on my Allis Chalmers 620 loader. It uses a belt driven pump and the system is rated at 1250psi.
