Everything is complete for my B with the exception of the over-run clutch. I slips right onto the pto spline of the tractor but how does one lock it into place? The clutch has two alan type set screws but in looking at them I do not see how these would hold the clutch in place, and rather than trying to screw them down to see what happens I thought I would ask the question here first. My tractor's pto spline does not have any grove for these to catch on, nor does it appear that these set screws would protude far enoungh through the clutch to do anything. There is a small hole in the shaft of the pto spline, but nothing on the clutch that appears to line up with this. I have included a link to my newly created home page with pictures on my tractor page and one of the clutch. Thanks for any advise in advance.

On the one that I have, there is a roll pin that goes in and engages the notch or groove in the PTO shaft to hold the clutch unit in place. Remove the two set screws and see if there isn't a hole all the way through. The roll pin should've come with the clutch.

Thanks for confiming what I thought. The hole in the PTO shaft is smaller than the roll pin and I was not sure if that was the proper procedure. I guess the roll pin will collapse to fit the smaller hole in the PTO shaft. I did not what to force anything until I got confirmation. I live in St. Louis and my bro-in-law got the clutch for me in Lebanon, Mo. so I did not get a chance to speak with the guy at the tractor supply store. I knew I could count on someone answering my question on this or the other forum..

Thanks again
