MW hydraulic pump drive key needed

[Mark Scholten]

A couple of years ago, I installed the MW aftermarket hydraulic kit on my 47 D. The other day, the pump wouldn't engage. I took the pump off and found the problem. I put it back on and when the tractor fired, I heard a crunch. Of course the engine died. I pulled it back apart and the drive key was broken. Something in the mag locked up and I am surprised it didn't bust the mag. Anyways, I need a new drive key. Any sources you know of? Obsolete from mother deere.
Thanks, Mark

You might have to make your own, but this thread gives the dimensions of I think, the key to which you are talking about, if you mean the driving lug that fits between the pump and the mag. If not, you might want to be more specific as to the location.

Thanks Frank. I have the dimensions, now figure out how they fit. I can harden the piece when I'm done. The problem will be to find .312 key stock unless that's normal.

.312" (5/16")flat, ground stock should be pretty standard. Try Enco for a blank.

Mark,
What was the problem with the pump not engaging?
