Just an update for a question I asked earlier. I'm working on a 80.
Seeing the state of the couplers and the pump shafts, I looked around for sources of parts.
Richard Duane at 410-643-2899 is one of the major suppliers. He has the steering pump main shaft for the 80 series, to the tune of $300 or so. Not his fault, but just out of my price range at the moment, especially since my shaft only has one real defect, the keyway. I did talk to him, a very nice guy.
I found another supplier, George Persinger, of http://www.greenpartsofva.com
He can supply most PS parts, including the pump idler shaft, as well as the couplers, for a much better price then Deere. And after reading his site and talking to him, I found that he tightened the tolerance on the splines in the coupler, the original Deere parts were a looser fit for easier assembly, and he closed it up for a tighter fit, though it will still fit on the original splines with no issue.
I ordered a coupler set from him, as well as the pump idler shaft (the bad keyway, and the new one was cheap). After receiving them, I found his claims about the couplers to be entirely true. They fit nice and smoothly on the pump shaft, and fit VERY tightly on the long driveshaft. I had to force them on with a hammer....which is not the fault of his coupler so much as my splines were very beat up and likely distorted. The driveshaft under the crankcase, I tried it gently and I do believe the coupler will fit TIGHT just like the others, I just don't want to do it at the moment so it's not stuck! haha
The long driveshaft and the pump main shaft
The pump main shaft was in OK shape....except for the keyway. It was toast. A shame to junk a part with only one defect. I talked to a machinist friend of mine, and we figured a solution, he milled me a new keyway away from the old woodruff key, and provided a nice heat treated hardened rectangle key.
The old worn keyway
The new keyway
Hopefully this helps some people and gives some ideas for others to do their own fixes.
