Looking at the tapered end of your coupler, I think I can see the slot for the key. If it is still there and there is also a slot on the drive shaft you may be able to get a key in there and remove the shaft that way.

On my 202 there was a woodruff key and also a square key. I think the woodruff key was between the pump shaft and the coupler and the square key was between the coupler and the drive shaft. If yours was the same you would need to try the above with a square key.

the shaft unscrews from the mount on the pulley. But the weld on the shaft that the keyed coupler is connected to is where it broke

I recently got my grandfather's old MF65. It also has a Davis 102 loader with the front hydraulic pump.

I need to take the loader off to get to the engine. How does that pump attach to the shaft? Does it have splines into the pump or a press fit. I don't want to bang on it too hard and break something.

Thanks.

the pump shaft is keyed and fits in a coupler

are the 3 bolt the only thing that hold the shaft coupler to the crank pulley?

Yes. And the shaft unscrews CLOCKWISE (left hand thread) from that crank adapter.

Make sure the holes through the crank adapter are good and not wallowed out. If the holes are good but the bushings are shot, they're still available from the dealer.

Thanks for your reply that is what I thought but just wanted to make sure before I cut the shaft at the adaptor. I think it will be easier than removing the front axle and shaft support bearings..

thanks again

You're welcome. If the crank adapter (the three bolt flange that's bolted to the crank) is still in usable shape and you have to cut the shaft off of it, you should be able to weld a nut onto what's left of the shaft, hold the adapter in a vice, and spin it out. Just remember, left hand thread- it's righty-loosey. :) That trips up a lot of people!
