[Ford-ferguson] TO-30 Hydraulics

[Robert L. Holtzer]

I have a TO35.  A local shop told me the first thing to check if the lift 
goes out -- the upper and lower O-rings on the pressure tube between the 
pump and upper casing.  I gather they can look relatively good but still 
allow a major leakage.  Your crack may or may not be the problem -- suggest 
replacing or brazing.
