In Reply to: 3414 Hydraulic pump posted by Dustin Medders on April 18, 2014 at 10:24:27:
Any pump can be any GPM depending how fast it turns. You need a pump that is around 2 to 2.5 cubic inches per revolution. That would have a rating of around 17-24 GPM @ 2000 RPM. The 3414 takes the same pump in front as a Ford 4000 with a backhoe/loader, Case 580CK, John Deere 350 or 450 crawler-loader, etc. Very common. In your sitution - one thing to consider. The original setup with the 3414 came two ways. One had a pump with a keyway insteaad of splines. That was just the early ones. Then they used a pump with a small splined shaft and a special driveshaft with one small end (to fit the pump) and one big end to fit the spline drive on the crankpulley. Your best bet is to just get a standard pump with the 7/8" X 13 splined shaft and use 7/8" X 13 all the way. This way standard Case, Deere or Ford parts will fit. You can buy all the coupler parts here on the Website for a Ford loader. The original pump on my 3414 was a Cessna/Eaton 2.33 c.i. per rev, # 25504LSA, serial # D971027BB, SAE B two bolt mount with SAE 20 on the inlet and SAE 12 on the outlet (both female ORB). Set up for counter-clockwise rotation when viewed from the drive end. This is the correct pump from Cessna. I used a Webster-Danfoss on mine only because I got a better buy on it. Mine was $280 new. Webster makes pump with the exact same dimensions as the Cessna.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
