Consensus is good! :D :lol: :lol:

Sorry to hear you are getting the shaft :? . I just did that job in my 1950, but not because of the PTO, but to R&R the shaft to retrofit a sealed bearing. The shafts are induction hardened and are the inner race for the bearing that is located at the rear of the shaft. When the bearings fail, the shaft deteriorates as well. By turning down the shaft a few thou, you can fit a sealed bearing and still use a shaft that would be too damaged to use with an original roller bearing. Just something to be aware of if shopping for a used input shaft. Any with a bad bearing surface should cost a lot less but still could be used if you have access to machining. A tool post grinder would be the best way to machine the shaft because it is hardened, but we were able to turn it by taking very small bites per pass.

Warr, to answer your question
is that how it's suppose to look? Also the transmissions shaft is toast.

Here's a pic from TM showing how the pto "clutch" should look

Also, if your tranny shaft end is toast, most likely the pin on the lever/shaft is worn and will need replaced
Image

It's fairly easy to remove, now that the pto assembly is removed. Reach in and feel the pin for flats on the sides. If it's not perfectly round, I'd replace it to get max engagement of the pto "clutch" with your new tranny shaft :D

There'll be some other suggestions and cautions(installing front tranny seal backwards) once things start going back together.

Don't forget to wedge the front axle before splitting the cub. Safety first.

I just had this problem with my 49 Cub, there is a fair amount of play between the engagement pin (16) and the lever (15) that combined with the bent pin I was able to get it running !

Just wondering if any of the Canadian members know where I can buy the lever and to I replace it from the back or down thru the top

Thanks

Personally I would just order it from Tom and Lynn at TM Tractor. They are closed though until July 5th ..

It is a good part according to Messicks - 07-13 DRIVE TRAIN, BELT PULLEY AND POWER TAKE-OFF
LEVER
LEVER AND SHAFT ASSY, power take-off shifter, units A, B and C

So your local CaseIH dealer should be able to get it. Don't ask for them to special order it though, it will cost about double. Let them bring it in with their usual order - will be cheaper and will bypass the postal strike. Make sure you give your dealer the part number and the link to it in the on-line catalog ..

Does that help?

all great info.and right on. as the above pictures show the input shaft / driveshaft splines chewed up. this is cause as stated but I might add that over years of PTO use the splines get worn in a slight wedge shap. the wedge shape pointing tords the rear. Being that when the shifter coller is only inguaged slightly over 1/4 " when slid over the driveshaft splines under a load the coller is always trying to be pushed tords the rear. This puts excessive force on the shifter coller pin wearing it out. It would be wise to replace the driveshaft if it is showing anyting over a slight roundness of the spline ends. Also check the coller. I never saw a coller worn till today. I saw my first coller splines worn out. This is a first for me since over 35 years of rebuilding farmall cubs. It is very important that the pto bushing be in good sape as well as the PTO pilot shaft. Keep in mind that when all componets are in proper shape the shifter pin really only works hard when shifting it into gear.Very little force is needed to hold it inguaged. But still the original shifter pin is of hardened steel and the aftermarket pins are of soft steel. I learnded the hard way :oops: so I now drill out the original shifter pin ( 1/4 " ) then get a grade 8 or higher 1/4 bolt. insert into hole and tack weld on back. cut to lenght. will never wear out 8)

My 49 was doing the same thing, after looking into it I noticed the PTO shaft slides in and out, this is likely causing me some of the issue. What holds the shaft in place ? Just the shifter pin ?

On the early tractors the pto is held in place by staking the rear bearing to the shaft. The later tractors had a groove cut in the shaft and a snap ring keeps the bearing in the right place on the shaft which keeps the shaft from moving.

If you can't fix it with a hammer, you've got an electrical problem.

Thanks again ! I took it all apart, is it safe to assume (I know I know) that the busing....Illustration Part number 3...IH part # IH360256 is what holds the PTO shaft in place ?

Does anyone know if the dealer will still carry this part ?

How would I go about staking the bearing to the shaft ?

With the bearing in place on the shaft use a center punch or small drift or pin punch to stake the shaft at the edge of the bearing. There are some pictures on TM's website.
