1.25 Six Spline Outside Yoke?!

[ChillyB]

I bought an old post hole digger than needs some driveshaft work. The gearbox pinion shaft is 1.25 x six spline. The current yoke has worn out pin and block u-joint, and the ears appear to be slightly twisted. I have another drive shaft but the inside yoke is a cross and cup type u-joint.

Where in the world does one find 1.25 six-spline yokes?

used to be very common, from the 8N days, still around, google 1-1/4 6 Spline Bore yoke

Well, in all my 77 years, I have never seen a 1-1/4 pto spline. N series Fords featured an 1-1/8 pto spline, which was pretty standard prior to WWII. Perhaps the poster is misreading his tape measure. Would be easy enough to do with old worn splines.

No error. Used calipers. I searched many times but with terms 1.25 Six Spline yoke, no hits. I typed exactly as recommended and danged if I didn't find one! Thanks a lot.

Something like this?

Well, sort of. My current shaft is the
small size rectangle telescope shaft.
That joint series fits only the larger
size rectangle shaft. Since its the only
yoke I can find that fits 1-1/4 spline
shaft then I guess I'm building a
driveshaft from the implement forward.
Sure hope the digger gearbox is functional
after this...

Also, it's the IMPLEMENT yoke, not the PTO yoke. But yokes is yokes and it's still uncommon as heck. Which makes it super collectible, right?
