PTO Spring

Postby derski69 » Fri Feb 03, 2017 3:51 am

Good Morning.
When I bought my '53 Cub the owner said it needed a new spring to keep the PTO engaged so that my woods mower would work properly. My father in law plans to use this tractor come summer to cut grass around the farm so I'd like to get the parts I need for him to fix it himself. I'm not sure where is spring is or where I can get one can somebody please help me?
Thank You.

There is no spring in the Cub's PTO. There are a couple of parts that normally need replacing, the shift lever and clutch coupling.

Parts are available from the advertisers on this site. It's not a difficult task to repair the PTO.

Use the search function, looking for the PTO. There will be photos and explainations in the How To section of this site.

There are free down loadable manuals, above. Suggest starting with the Operator's Manual, then the Service Manual, and the Parts Manual.
I have an excuse. CRS.

There is, in fact, a spring on the PTO shift lever.

That's why I have CRS in my tag line.

Not sure why the spring would be missing. But, I would tear down the PTO, check parts condition. There is a good chance the clutch, power take-off shifter (351 286 R2) and the lever and shaft assy, power take-off shifter (351 287 R11) needs replacing.

Hi,
Here is a post with info about the PTO from a few days ago.

viewtopic.php?f=1&t=95516

There is a small spring on the PTO lever, like they said above. It keeps the lever up, so it locks into the ends of the slot in the PTO shifter guide, it is called in the parts book. Here it is below at TM Tractor, like Don posted above. There is a pic below it showing where it goes. There is a small cotter key at the bottom of the shifter rod that you remove to take it apart.
Sometimes the splines on the end of the long clutch shaft, in the transmission case, and the splines in the PTO clutch wear out, and then the PTO won't work. Then the parts need replacing.
Here is a pic from TM Tractor showing the rear end of the clutch shaft, the splines are on the right of the pic. :)

Thank you for the info guys. I'm not sure the spring is missing but it maybe wore out. The guy I bought the tractor from said that he had to hold the PTO lever to keep the PTO engaged. Hopefully this summer I'll be home so I can take a look at it.

I just repaired a pto on a friend's '53. It had a similar problem. It wouldn't engage or stay engaged.
The main problem was the shifter pin that fits into the clutch collar. It was worn down to less than half of what it should have been. I replaced the whole shifter assembly (it comes with the spring). I also ended up replacing the pto clutch, as the splines were worn on the old one.
Worked like a champ afterward.
Why is there never enough time to do the job right, but always enough time to do it over. :?:

Hey guys.
I wanted to follow up on this post. I just got the cub back from our local Cub Cadet dealership the last week. Come to find out there was a couple of bad bearings and one bad gear in the transmission that kept the PTO from staying engaged. The fix only cost me $241 with a carb clean so I don't think that was a bad deal. My father in law has been mowing the pasture with it and loving since he picked it up.
