The back half of the shaft assy for external hyd pump for FEL on a L245DT is stripped of it's teeth. I'm looking for a used part or suggestions to get this operating again. 
Hi LanceHello Bill
I repaired a L225 a few year back with a taper lock agreement.I believe we used a 1" taper lock with a chain coupling . The taper lock will lock down on the splines and not spin.You can get these parts at your local bearing supply. The unit we repaired is still in service.The other option is to plumb in to the tractor hydraulics. The loader will work about 3/4 as fast as it does with the front pump.
Good Luck Lance
TractorBill, Thank you for posting thise helpful pictures. I am having a similar problem. My splines are worn off, I have two set screws, the head on one is sheared off, the other broke on removal. There is a large hole on the opposite side that a set screw may have been there, but can not tell. I can not remove the shaft from the crank as perhaps the set screws are prevent that? The chain couple works but is badly worn. The L245DT has 750 hours on it, I got it with this farm. I'm new to Tractor Talks (this is my first post). I can post a picture if I get a reply and would welcome advice. I think I may have to drill out the set screws and pin to the crank but would like some advice since I'm a novice but like to try.MagKarl, Here are some photos of the end of the crankshaft, overall shaft assy and inside end of shaft coupler. I interest in hearing what options there are outside of spot welding coupler to crankshaft. Thanks for your imput.
