Peabody: That's interesting, the IT manual I have calls it a seal and doesn't say anything about it being optional on some pumps. The seal shown presses in from outside of pump housing around shaft going into timing gear chamber.

If indeed fenton has a pump with no seal in that output shaft, he may as well toss it on the scrap pile and find another pump. The other item I notice, you are spelling it Pesko and my IT manual is saying Pesco.

Another interesting item, it is now 47 years since my dad bought the 130. Over the 47 years I've owned 6 of these tractors, and I've yet to take a hydraulic pump or touch control unit apart. I've removed the pumps a few times doing other work on tractor. We learned very early on Farmalls one fault on hydraulics was much too small resovoirs. Even the slightest leak had to be dealt with quickly, or you ran the danger of system running dry. Hydraulic pumps will operate without oil just about the same length of time the engine crankcase will run without oil.

I guess the hard lesson we had was with Cockshutt 540 and Wagner loader with a front mounted pump, having the high presure line runing along loader frame to valves. Wagner also used the tubular sub frame as a resovoir My kid brother sheared that high presure line loading gravel. Of course he lost all the hydraulic oil in about 30 seconds. Since loader was in raised position, he thought it would be ok to drive the 1/2 mile back to farm. When he got there you could have cooked dinner on that pump. Expensive lesson even back in 1961. Dad brought in a new set of rules, if in doubt with oils, "SHUT IT DOWN". That is when we noted the Farmall 130 held 8 pints and 300 very little more. Even the Cockshutt, the onboard system for 3 point hitch held very little more. The loader did hold about 12 to 15 gallons. Dad's next new rule was every time you check the engine crancase oil (daily) you also check the hydraulic oil level as well as rad. That rule has served me well.

I know this is a bit long winded, however I've felt for sometime, most of these rebuilds on touch control systems, both pump and touch control unit we read about here at YT could have been avoided had closer attention been given the system. That little pump out of oil for 30 sec. will be toast. I think touch control units have been adversely affected by sitting around low in oil thus allowing rubber and leather to dry out. Now I realize when you buy a used tractor, you have little control over what previous owner did.

By the way Peabody this little lecture was not for you. I think we are however seeing an unprecedented number of guys with relatively little experience buying these old tractors, many of them to basically do yard work on and under 5 acre property. When I say little experience, I bet most of them had some at grandpa's farm 30 years ago. That is why they are seeing these oldies as a much better buy than what's new on the market. I feel that the old hands here at YT should not only tell these guys how to fix or repair your own, the time is here to tell them how to avoid some of these problems.
