I need paper on hydralics for this tractor . Does anybody have some .

a Serial number would help to get you the right info. what part of the hydraulics are you looking for valves. pump, lines? you seem to be very vague. I am sure there is a manual in our online library if you are a paid member of ACMCO. if you are not the cost is less than buying a manual from ebay or other places.

Yes, already a member.
Are you talking transmission or blade hydraulics? If blade what's the s/n on the hydraulic tank and you should provide the s/n of the tractor too. Also, what's the issue?

27H679A is the serial no.on Hydralic tank . Machine serial no. is 66A11131 Need to hook up Cat Ripper up 50G909 . Can't find any hydralic info any where . checked E-Bay and went to Fabic CAt no help. NEED INFO PLEASE HELP

My books don't recognize the "A" as part of the Hydraulic control s/n. Late units are effective with 27H6324-up. It would help if you could identify if you have a single, double or triple control valve.
The normal ripper is a 9Dxxxx ripper (double barrel). Is a double barrel unit that your wanting to hook up?
Are you just looking for the hydraulic schematic or actual plumbing and linkage to hook up a ripper?
If it's not to messy I may be able to help with information or I can direct you to the literature you need to sort it out yourself.
OK, forget triple valve, that would take it into the 28Hxxxx series.
Depending on what you are running (blade or blade plus tilt) it looks like there may be a problem adding the ripper unless you going to use the blade circuit for the ripper. Getting to a blade plus ripper requires a different tank and valve arrangement.

Yes its a Double barrel ripper. Looking for plumbing and hydraulic schematic. Can tell me how or where can get the right tank that I need got tilt and blade controls . I didn't know they made a tank with a third valve. Fabic sold me a 7J-8016R valve but noway to hook up.

You will need a 28Hxxxx series (triple valve) #193 Hydraulic Control.
This is the arrangement for 66A8055-up units and the Hydraulic Schematic






 

For comparison this is what you should have now with the 27H control.

If you dig into the individual parts the 27H and 28H use the same 7J2772 tank/cover and 6J1054 base plate. If you can get the individual parts it's possible to turn the 27H into a 28H. The ripper valve original part number is a 5J2956. I don't know off hand if that is superceded by  your 7J8016R
