Looking for some hex tubing or bushings to fit a 7/8" hex hub to a 11/16" hex shaft. Does such a thing exist? I'll only need about 6 or 7 pieces 2" long.

Maybe not in the right category, but I'll be using it on an Allis planter...

Is that the size of the hex setup on the DA 385? Dale

Yes, the line shaft/drill shaft across the back is 11/16". Any of the row-clutches I've found are made for 7/8" hex. I could change out the shaft to 7/8, but then I also have to change bearing hangers and the main drive sprockets.

This is where I go, if they don't have it, I go to my friend who is a machinist.

Get a 6' length of 7/8 hex stock from Mcmaster Carr for $27 and have adapters made with internal keyways. Cut the old shaft into segments and have the ends turned round with keyways. Assemble the shaft in sections on the machine with setscrews holding it together.

Is there any hex PTO telescoping drive shaft out there of the right dimensions? I find plenty of splined couplings and adapters, but not much hex.

I don't know how small a lot they will sell:
