(quoted from post at 16:47:58 01/17/19) It looks like there are 2 problems with your plumbing reroute to add the extra oil. The first is that the front plug should not have been just a plug but a plug with a long screw, a copper washer and a lock nut on it (you can see it on page 71C). This screw holds item 28 on page 71C into the hydraulic housing. The oil from the hydraulic pump goes through this line from the pump to the control valves.
Go here to get to AGCO parts catalog: *http://agcopartsbooks.com/PartsBooksN/Viewer/book.aspx?book=agco/r1157c00* Highlight the line between the *'s & click open in another tab.
The other thing I see (I think) is that the small line that connects to the top rear of the hydraulic reservoir appears to be connected to the rear one of you fittings to your tank. If this is true, oil under pump pressure is being force into that fitting. That fitting/line is supposed to be the breather for the hydraulic system and is to be connected to the fitting at the other end of the PTO handle bore in the rear end housing. The rear end housing then allows both system to breathe through the J shaped tube near the front left of the plate between the rear end and the hydraulic housings which has a "bottle brush" in it to keep out bigger things.

Thanks for the reply
I have to get permission, from an ARCO Dealer, to get into the AGCO catalog, so I will try tomorrow. But I do have 3 manuals for this jet star, Operator Manual #S-258,Repair Catalog # R-2013A(Basically a Parts
manual), and Shop Manual #MM-14.
In the parts book and the shop manual I see a picture of what you are talking about. I did not remove them, and nowhere in any of the manuals does it explain what that does.
The parts Manual gives the specs on the pieces
ITEM #
31-GM138684 , set screw 5/16"-18 x 3-1/2" long
30-10A9442 Nut- pressure tube set screw
32-50A1041-Nut, stop 5/16"-18
33-10A6386 Gasket- set screw nut (lead). 5/16" ID. 17/32" OD
34-10A3397 Gasket- set screw nut, 11/32"ID. 5/8" OD
Would it be possible to locate them?
The 3/16" line , I believe you are referring to, actually is the vent line from the HYD sys to the Differential. This line is the way the book shows it to be.I do have the breather tube you are referring too, but the brush has been missing. I changed it to a 90 degree, so so it would be harder for anything to enter it.
any suggestions would sure help.
Just an FYI, I was getting fluid in the diff. before I add the reserve tank. Thanks Again
