PTO wobble

flyingace · Mar 9, 2022

1966 Ford 3000. Just replaced the PTO shaft seal. When I put everything back, I had wobble in pto output shaft. When I disengage the PTO, it spins true when spun by hand. No problems engaging and disengaging at the lever. No funny noises.

Could this be a bad bearing or bent shaft? How can I diagnose this to fix the problem?

Thanks,JK.

probably a bent and or twisted pto shaft. I would pull and inspect the shaft.., bearing housing and if necessary, the coupler. I usually see a twist near the front splines, in some cases, where I have to force the pto shaft out of the coupler.

I took the shaft out and spun it on some v-blocks. It ran straight until the last 5-6 inches (of the external end). The bend starts logically at the bearing. Wobble is around 7-8 thousands at the bearing and about an 1/8 inch at end of shaft. Is this shaft toast or is there a way to straighten? New shaft, bearing and seal is around $120 with shipping.

A 10 ton hydraulic press might straighten it out if you know what you're doing with it.

Thanks.
I tried a 12 ton to no avail. Probably not getting an actual 12 tons out of POS press.
