Well I got the one I have welded up and it looks good. Now the question. Can I use a 3/8 grade 8 bolt in place of one of the pins on this. The problem it had when I got it was a broken part of 2 and what caused the broken parts where the one pin broke and then let things get out of whack. So I don't have a good pin but figure a grade 8 bolt will work. What think you guys??
Thanks

I wouldn't have a problem using a hardened bolt, if you take the proper precautions against having the nut come off. I would buy some the orange Loctite that only lets go when heat is applied and also batter the threaded end of the bolt with a hammer after you put the nut on.

I'm using double lock nuts on it I figure that way they will not loosen up and come off

Single lock nut and a cotter key...? I suppose it would be best not to have any threads contacting moving parts, thus you would have only as much threads as the nut will cover.

Hi Old ., For what it is WORTH..... ... When this happened to Me 15 years ago on My 51 DC , , We sinply took a bolt and double jam nutted it ,, Runs fine without vibrations or problems , Use the old gent DC on the 489 haybine , No till planter , feed Grinder , and Tractor Puller .. Glad to hear You were able to get this repaired , Ft clutcher parts are hard to find ,No help from my parts people around here ,, Not sure what caused this for Me other than cotter key pin failed , While You are in there ,Check input shaft bearings on tranny , for excessive slop , Best wishes

This one is the hand clutch but the one that has live PTO. From what I have been able to find out they where only made for about a year and a half so yep parts have been hard to find for it

Some hardware stores carry those kind of pins. Also bearing companies such as Precision Industries would have them. I would replace all three so as not to cause an out of balance condition for your engine. All the pins should weigh the same.

Old;
I believe I would be more inclined to manufacture a pin from drill rod... Gene
