I Wallered out the key way on my shaft also messed up the yoke. So I am replacing both. My issue is that the shaft is 3/4 with a 1/4 key way. the yoke I got is 13/16 with 1/4 key way and is a little loose on the shaft without the key in. Is this right? Mudbuddy is not answering or returning calls. I got a 3/4 yoke too but was told the 3/4 yokes only come in 3/16 key ways and have a super tight fit. I've talked to several pto supply shops and find some research and found it to be true. So do I use the 13/16 yoke with 1/4 key???

I've gotten 3/4 yokes from napa with 1/4 key, as well as for driveshaft parts. Com

Backwater sells them also. Check them out.
