Hydraulics for Cat 22

Hydraulics for Cat 22 was created by TerryinNorCal
Hi all.... seems a while back I remember someone using a power steering pump? mounted up front of a Cat 22, powered via the fan belt system, or crank pulley. Was I dreaming on this? If not, can someone remind me of what they used, and how they hooked it up? Many thanks ahead of time. Terry
P.S. Photos would help, but not necessary.

Hi Terry - I used a 12 GPM hydraulic pump run off the fan belt when I shopbuilt my 3-point hitch conversion many years ago. The mounting bracket doesn't show in the photo, but it's vertical and I fabbed it out of 1/4" plate with slotted bolt holes on the bottom for belt tensioning. - Richard

Thanks CatSpotter for your input. What did the pump come off of to have the proper width pulley for the belt?

Terry - I bought the pump (not a power steering pump) new from Surplus Center and dredged up the "B" width pulley from my scrap pile.

If you wind up deciding to use a fan-belt driven pump, give me a holler and I can send you photos of my pump mounting bracket. Somewhere I have some old B&W photos of the entire hitch fabrication process. - Richard

thanks for the info again CatSpotter. I apologize for the delay here, as I was up on my ranch rootin' stumps for a new road.

Terry,
One of my friends removed a pto driven pump from his 22 when he restored it. If you are interested, I will ask if it is for sale, and how much.

Thanks for the offer Soapy, but there is no PTO drive off the back of this machine, so I was trying to find an alternate method to run a hydraulic cylinder on a disc unit.

My 22 runs a mounted pump on the accessory drive on the right hand side of the engine under the governor and magneto mount. Its got two bolts that hold it on. The gear stayed in the engine and the pump pulled out with the key in the shaft. Just going off memory. Its been 5 or 6 years since I pulled the engine out of it to repair the throwout bearing.
