[AT] JD 4010

[Alan Nadeau]

Al,

Unless those couplers are way different than any I have seen you don't have 
to take them apart to replace the O-ring, assuming it is the ring that seals 
onto the male connector when they are in use.  To replace that one you dig 
the bad ring out with a pick and roll the new one, well greased, into place 
with your fingertip.   If there's another O-ring in them I have never been 
forced to deal with it but I have gotten pretty good at changing the one I 
know about.  Although all of mine are the little ones on garden tractors I 
have messed with the ag tractor ones some.
