Hydrolic pump

Phil andree · Oct 25, 2016

Ok so I blew a front seal on my 350 crawler loader backhoe
Got the pump out but the shaft that it slids onto seams to have come out as well
Can't seam to get it back together
Looks like it goes into some fork like a govener or something for easier acces to front of motor does the three bolts either side of machine let the front hood tilt forward to get at this shaft
Any help will do guys. First time taking apart

No.
The bolts hold the front cowling on.
If you need to go there you need to remove the hood, and grill, radiator hoses and cooler connections, then with suitable lifting
Device you can lift the whole thing out and up out of the way.
It's heavy. To bad it don't tilt.

I can't remember if your pump is driven off the Crank pulley
Or timing gear?
I thought the main Hyd. pump was driven off the pulley.

Those two-piece driveshafts with the yoke often got converter to a conventional one-piece. If that seal blew out of that Cessna pump - it likely means you need a new pump. The seal tends to blow out when the pump gets so worn, high pressure reaches that seal and pushes on it. It's a generic pump rated around 23 GPM at full engine speed as I recall and there are lots of generic Cessna and Webster pumps that work as replacements.

Do you know where I get a new one

Surpluscenter.com is a place I use quite a bit. New Cessna pumps are getting pretty expensive. Your Deere uses the same pump as many Ford, Case, and IH backhoe and loaders do, so it is pretty common. http://www.surpluscenter.com/Hydraulics/Hydraulic-Pumps/Gear-Pumps/2-05-cu-in-CESSNA-25503LSA-HYD-PUMP-9-4066-C.axd
