[Farmall] Touch Control Hydraulics

[szabelsk at gdls.com]

Had a similar problem on my Cub. What happened is that the hydraulic lines 
had been brazed by the previous owner. As I would use the hydraulics the 
braze would break and I'd loose all the oil. I'd have it fixed and then it 
would break again, and I would lose the oil once again.This happened 
several times. I finally figured out that when the previous owner fixed 
the lines the first time, he bent the tubes a little and they were under 
stress when I would bolt them in. That kept causing the lines to break. 

What eventually happened is that I had run the pump dry several times and 
the front seal failed. I would keep adding oil to the reservoir but it 
would always be low or very near empty.  Noticed that the oil in the oil 
pan was getting higher every time I checked it. Pulled the hydraulic pump 
and found that the seal was almost rock hard, more than likely from being 
run dry and the high engine operating temperature. Replaced the hydraulic 
pump seal and the problem went away. I had to keep an eye on the hydraulic 
lines for new leaks until I was able to get a new set from one of the 
local parts sellers. 

If you don't have any obvious leaks anywhere, pull the hydraulic pump and 
check the condition of the seal. I think I paid less than five dollars for 
the seal kit. It's been almost five years and I haven't had to top off the 
hydraulic system yet.
