[AT] pipe threads

[John Wilkens]

Ken, a side issue....I have a Case VAC which has the low pressure cam 
gear driven hyd. pump.  I found that the return line fitting to the 
pump is not any standard hyd. thread that I could find.  Our hyd shop 
couldn't come up with anything either.  Finally decided it was a 
fitting common only to Case.  I finally bought a piece of used line 
with the fitting on it from a parts VAC and fashioned a new line that 
way.  Good luck.    John W.
