My mower deck coupler at the mid mount PTO has a plastic sleeve and it cracked and failed requiring a new coupler, I'm told. Part # k5763-31150. 1. Is there a generic part to replace this? 2. How does one remove the universal joint with the clips on the inside of the u-joint yoke? (I tried to compress with C-clamp with no results.)

Has anyone been there and done that?

Not on your particular mower, but have replaced too many u joints to count.
Usually a small punch with a blunt end will roll the clip out. But if you put a c clamp on it, the clip may want to spin. I jam it with a screwdriver on opposite end.
Take your time, if a needle falls over you wont get the clips back in, and a good chance you break the needle bearing.wiping inside cup with grease helps keep needle standing.

Im not a betting man, but i bet theres a youtube video on u- joint replacement. If there isnt there should be.

Did i mention the driveshaft should be carefully clamped in a vise?

Really appreciate prompt response. You confirmed my suspicions about how to remove clips. I'm being careful as there is no Kubota dealer close by for replacement parts. What is a "needle"? I looked for a video but only saw the standard auto stuff with the clip rings on the outside of the ujoint that are simple to remove with needle nose pliers. Thank you.

The needles that Tooljunkie refers to are the little rod shaped rollers that are the bearings inside each cap on the universal joint. They are in all u-joints not just Kubota mowers.

Thanks guys. I finally surrendered to Kubota and ordered the OE part after searching for generic, but will try to rig the broken part to see if I can get a few more weeks of mowing out of it. A similar (not same) part at local farm supply is all steel and sells for $38 and Kubota part has plastic and is $93 or $160. Go figure!
