Borrowing 28 GPM of hydraulic oil from 806

I need to borrow 28 GPM of hydraulic oil from the trans/rear end of my 806 and draw it threw a inline filter and on to a Vicers pump being run off the 1000 RPM PTO shaft and on to a Backhoe attachment. I am stuck on what is the best location to get the oil from.

The largest drain fitting in the bottom of the castings is ¾” NPT, can I draw 28 GPM thru a 3/4” NPT nipple? The rest of the plumbing will be 1”NPT.

If ¾” isn’t large enough, how risky would it be to Drill out the Casting and Tap it to 1” NPT? (I don’t want to do this).

Or can I remove the Filter Cover and drill a hole big enough to Weld in a 1” NPT nipple to get the flow I need, and would it make a difference where on the Cover this was done?

TIA! Dave

I would have to look it up but I don't think a 806 holds that much hyd oil so you would be running the entire cap. through every minute. I am thinking that fluid is going to really build up heat. just my thoughts Brian.

Not sure if it'll work for 806, butI added 23gpm loader front pump to 485, and took supply from 1.25" plug under right axle and overfilled trans. But...also added a 24 X 12 cooler with elec rad fan. Temps run 150-160 @ 90 ambient.

I would not do it. Install a tank on the side or front of the tractor with a reserve at least a large as your flow per minute. Cycling that much oil that quickly will over heat your tractor hydaulic system quickly.

I think I would use a external resevoir. You will need a lot of oil in the reserve.

Don, I thought about doing that but how big should it be? Where would I mount it? How would I keep the oil cool?

The tractor has all of this. I just need to get the oil out at the correct GPM. Thanks for your help. Dave

I really don't believe that at 28 gpm the 806 will have enough fluid on reserve or be able to control the temperature. At 28 gpm you are going to recycle that oil what 2 or 3 time a minute. Sounds like a disaster waiting to happen.

the 3/4" opening may be sufficient if you don't narrow it with an adaptor. see if its practical to install a flange fitting. if the opening area is flat you need to work the casting into a smooth finish around the opening and drill and tap two holes for the flange bolts. if the bottom casting is thick enough.(you can see that in the plug opening), you can drill blind holes. this is a no pressure line and the flange bolts only hold the flange and its tubing so the flange bolt holes can be shallow.
