Tractor loader rebuild

[Pete O]

A little more progress on the line-boring setup;
I finished the PTO output shaft  for the lathe.
This end is held in the chuck
   
and this bit sticks out the back end of the spindle
   
There's a tapered spigot that centres the back end in the spndle bore, forgot to take a photo. Nothing special there.

The other important bit is the driven end PTO adaptor. Splined one end and bored 25mm at the other end.
   
I used the shaper to cut an internal keyway in the adaptor. Don't know what I'd do without it.
   
Have to have a hole at the end of the keyway to run the tool into.
   
Cut a keyway into the shaft
   
A couple of grub screws to hold it in place and a bit of oversized key steel ground for a custom fit on the surface grinder.
   

I had to do a bit of work on both splined adaptors with a die grinder to get the driveshaft to slide on. Must remember to grind my horizontal milling spacer a tad thinner next time I do this. Probably had to take less than a thou off the splines for a fit.
Finally got the PTO shaft to fit both ends.
   
   

That's chewed up my days off this week. I'm hoping I may actually do the boring next week. I have to set up the bearing mounts to carry the boring shaft, hopefully that shouldn't be too difficult.
