PTO shift lever won't move far enough to engage collar on shaft.

Postby meandmydeere » Wed May 16, 2018 9:05 pm

I havn't done a PTO shifter in several years and I forgot all I pretended to know about them. I think the dog is wore that slides the collar back and forth. I don't remember how to get the shifter out of the trans to build it up. I have the top of the trans off, the plug is out on top and behind the cover, The shifter pull or push rod is pulled out of the side of the trans, I removed the small collar the shifter goes through, Now I need help. Let me guess, I have to pull the PTO shaft out the back and reach in to remove the lever.

Thanks in advance, Mark

Yes. In addition to the pin being worn, check the splines on the end of the shaft for wear, and the bushing.

And when you remove the PTO shaft, you might as well replace the seal in the retainer. I would also suggest you disassemble it to check to see if the PTO bearing could have moved...this can happen with the older PTO shafts that have the staked bearing (newer ones have a retainer clip). The staking can fail, allowing the bearing to slide forward, which in turn allows the shaft to move rearward. This increases the distance between the 2 shafts causing wear on the shift lever pin, or worse, grinding as the clutch can't bridge the gap.

Hi,
You did not need to remove the gear shift cover, the PTO parts are reached through the rear of the case.

Below is the PTO section from the Cub service manual, I would read it before working on the PTO.

Below is the whole GSS-1411 Cub service manual.

Below is a pic from TM Tractor of inside the rear of the case, the parts are gone thought, except for one bearing.

Did you try just barely letting the clutch out a little while in neutral ... just enough to turn the shaft while holding tension on the pto shift lever rearward?
After my new collar and going over the pto I still need to do that. Suspicion of the two shafts not being perfectly aligned. As well as the splines ,though shaft alignment is the bigger factor.

Everything is all fixed. The small nub that goes into the slide collar was warn 1/2 in to. I welded it up and it's all back together. All I need to do is check the 80w90 in the finals and I'm ready to pull at the 1st annual Cubfest. www.antiquefarmpowerclub.biz
