[Farmall] Drive Shaft For H Lift All

[szabelsk at gdls.com]

John,

Thought about the pump last night and came to the conclusion that the 
threads on the shaft would be right hand threads, not left hand threads. 
This is because the gear it drives would have to rotate clockwise, and in 
order for the coupler to stay attached to the shaft when rotating it would 
have to have right hand threads. I'll go talk to the shop this afternoon 
and see if they can some up with anything simple to make and get you their 
ideas. 

Off hand it sounds life maybe the end of the shaft has been essentially 
pulled into the back of the coupler and is wedged good and tight. That or 
the threads have been ground up and everything is just bound up for the 
entire thread length. I would assume that the shaft is a harder material 
than the coupler (?) so I would figure that the coupler threads may be 
damaged and the coupler would need to be replaced once you get them apart. 
Have you taken a good look at the couple and looked for cracks?  If there 
are any, then maybe the best thing would be to simply cut the coupler in 
half and get a new one.
