JD 790 300 loader

[dirt ditch]

The online specs I see for the 3005 are:

Hydraulics
Type Open Center
Pump Rated Output, gpm (L/min.) 9.4 (36.4)
Steering 4.2 (15.9)
Implement 5.4 (20.5)
Pump Type Single gear (Manual steering models); Dual gear (Power steering models)
Maximum Operating Pressure (PSI) 2050
Draft Control Type Position control
Remote Control Valves Available 2

That is weird. Last time I looked at the 3005 specks online it was what I quoted earlier. The online 3005 owners manual shows the higher hydraulic working pressure in the Specifications.

That is weird. I had never looked at the 3005 manual just the online specs and thought that they hadn't changed anything. I hadn't realized that they had changed the pump and the relief valve settings. I wonder which numbers are correct? Has anyone measured the maximum pressure on a 3005. Do anyone of the JD dealers know? If the rest of the tractor and the 300 loader handles it I might put in another shim kit. My TNT hoses are rated to 3000 psi.

It would be good to know what the 3005s hyd. pressure really is. I should have stated earlier that I do not plan on installing 2 complete sets of shims. just enough to get to 2600psi. Here is a 5 page thread on the subject. It is dated back to the 419 loader, but still great thread

Well... wont let me put a link to a a different Discussion Board. sorry.

I put the whole shim kit in and I'm goin tell ya'll what , it made a big difference. Before the tractor would barely pick the front tire off the ground, now it goes right on up at idle. And I just had to try out something heavy so I put up the back of my Chevy 1500 by the hitch. Its funny how a few mm. of shims can change all that. Thanks for the advise.

Is there supposed to be more numbers where the *** are?
I'd be interested in putting one of these kits in my 790. Thanks!

I just cut and pasted out of my parts CD so I don't know what the *'s are for. The number is AM875169.

My guess is the *'s are to show not all the text is there. Probably should say.

Mech is right. I still had the bag that the 4 shims of different thickness came in. here is pic of bag w/number.

Have it written down now. Thank you.

Hmmmm.....I ordered a shim kit from the part number in an earlier post a month or so ago....and my package included only 2 shims (at least thats what I remember seeing in the package...possibly they are stuck together??).

I am waiting for a hydraulic coupler to arrive...at which point I plan to assemble a wet gauge for before and after testing. I'd swear there is only two shims in the pack I got (each of 'em about 3/8" diameter by .050 thick??). I need to check my package again for the shim count (its in my tractor a few miles away).

Are all of you guys getting 4 shims in a package?
