4W-305 trouble?

My nephew's 4dub quit working in the field last week. Won't move and power steering is gone. He took hydraulic pump off and the splines on the shaft are wore down so it does not catch splines in the tractor. No parts available and none at salvage yards. Local dealer told him he should just salvage it. It's a really nice tractor to do that with. He doesn't want to salvage it. Any suggestions and help would be very appreciated. Thanks, rrhead(SD)

I have 2 4W305s.  I believe I have a NOS shaft that I bought to put in the pump.  Went to local hydraulic shop.  They were able to have a stacked pump assembly built that allowed me to hook up all the lines and manifolds that are bolted to those pumps.  That was 10 years ago though. If you tear that pump apart to change the shaft are all the seals available?

we have 6 4w305 -2 4w220 -2-7580 3-8550 go and get a shaft made and you will be money ahead.

I have new: shaft 70275649 and seal kit 70273974.   Effective SN. 1174

Thanks for all the comments. The tractor had no symptoms before this happened. Just like Mike's, it stopped in the middle of the field. I do like Mike's advise of putting anti-seize on when reinstalling and then doing it again. We have opportunity to get shaft and seals. Working on that and finding someone to work on gear in tractor. Thanks again, rrhead(SD)

With CNC machine work being what it is, making several probably won't cost much more than one plus a few bucks. Then put the original back in oilcloth and stored in a dry place.    David from jax

X2!! That’s exactly what I’d do.

Any idea how many would need to be milled before the cost of production and possibly a fair markup to himself got made?  The idea of taking an original and replicating sounds like an awesome deal for several owners! Was this a weak spot of those beauties??

That's a excellent way to do it. Get your money first and try to not have very many on hand. You probably won't sell very many of them, but if you had some other really hard pieces on hand, that people can't get the word would get around. I was thinking of gears in particular. These tractors that are given to gear failure would be a good place to start I thought. And really it's not difficult to harden and temper the right steel. We do it all the time making knives. And there is a chart to go by, how long to heat, what color to stop at and how long to leave it in the Parks 50 and what temps to temper at. There are lots of good used tools on Ebay that have prices that are not to bad. I really wish I was in good enough shape to do it, but at 76 there's not much chance. 

Does anyone have a picture of this shaft? My Dad runs a machine shop and knows where to have gears cut and stuff heat treated. I'm thinking 5 would be a good starting point.

I would take one.

How much, when and where do we send the money lol ?

hello you would not by chance still have this shaft and seal kit
