Thanks. I called around today, and either dealers were closed, or the guy that does such work won't be back until next week.
My wife suggested to take it to a retired diesel mechanic who lives down the road and see if he can do it. It took about an hour, but he got the job done. Ended up pressing out the old shaft thru the pulley. He then pressed the pulley onto the new water pump shaft. He wouldn't take any cash for his efforts, but I saw that he likes Mtn Dew, so I went down to the general store and got him a 12 pack and dropped it off on the way back home. I had to go down there anyway because we're still under a boil water advisory, and we needed some bagged ice.
Me and my BIL would have put all the new stuff back on the tractor today, but it decided to rain another inch. Was 82 and mostly sunny at 3:00, and now at 7:30, it just now stopped raining. I can't stand this weather. It's supposed to rain more tonight and in the morn. Which is bad because we have a the big annual family reunion to go to at noon tomorrow. We're under a flash flood warning for now.
Plus, I was planning on replanting my strawberry plugs today, and the tomato plants tomorrow. Now that and the repair will all have to wait another 2-3 days minimum. It was just starting to dry out a bit after all the rain earlier this week. I think we've had about 6", not counting today. Hate it, I think I'm getting webbed feet!
