Hydraulic Tech needed sorry - OT!!

[SHINTON]

Ok, I am hoping someone on here can help us out a bit since we have some folks using hydro on trail rigs, etc.

Dad bought(traded his MasseyF for) a Kubota L185 DT (compact 4wd tractor)

Now he wants to add a front end loader, so we are looking at various used ones out there for the smaller tractors.

Question #1: The hydro pump on the tractor now says it is 3.7 gpm, it is used for the rear pto / 3pt hitch stuff. We could "tap" into it with pancake or something dad knows about, but he is afraid it will be too SLOW for the front end loader? Some folks say yes too slow, others not really/depends on size of shafts (1.5" quoted as fine for them)



Question #2 is, assuming the overwhelming answer to above is YES, too slow.. Option A is remove current pump and install faster one, any ideas on where you would find one, google search letting me down.

Option B, there is a crankshaft sticking out of the front of the end, 1" approx, and splined like an axle. "Crankshaft Pump" has been throw around before but for the life of me I cannot find one.

What I DO find (say northerntool website, 40+ pumps) is a bunch of them with a smooth bore sticking out with a "keyed" edge on it. Not something my spline would stick into (I would need a female/splined input I guess)

So am I crazy...does such a thing exist, or maybe I am supposed to run a pulley or something? Or a gear setup or...beats the heck outta me.

Would LOVE some help on this, any and ALL thoughts are welcome!!!

FINAL THOUGHT...PTO pumps are for the "rear" I believe and would involve removing or modifying the rear/pto area, driveshafts for our implements and such...not to mention dads PTO stops turning when clutch pushed in and that is not what you want for pump for a Front end loader (is what I am reading)

Depending on the size of the loader yes 3.7 will be to slow, no it won't be to slow. That will all depend on what size rams you install to get the power you want. We ran a pump off the front output on a tractor and just made an adapter. Pretty easy to just build a splined to key adapter. Glad we did that instead of welding since two weeks later we found the right pump and it was a faster pump.

In the end it is up to your dad with what speed is acceptable. You can calulate the extension speed of a ram with that flow rate if you know the ram specs.
