Pto shift lever repair

[Gearhead94]

Looking for advice
In the middle of an involved rebuild of the family’s 1948 cub. It has been a 3 blade belly mower for the 30 years I’ve been around and found pictures from the 70’s as well. We have been replacing pto lever every 2-3 years recently. We do believe now it’s from the input shaft being worn. The issue I’m curious about is the fact I’ve always had to shave the lever to fit it in the socket inside the transmission. Can anyone tell me if I have a bad casting and that is why someone tried to chip pieces out or is this set up just not intended to have a pro?

any cub can have a PTO lever sits in the collar, imput shaft has a bushing inside it for the pto shaft to ride in and keeps it straight, bushing can be replaced

A photo would certainly help diagnose your issues.

I thought I didn’t but looks like the photo files are too big apparently to upload

Email the files to yourself. When it asks for the size, select medium or small. Then save the reduced files. You should then be able to attach them.

Hi,
Below is a picture from TM Tractor Parts of the PTO Pilot Bushing in the rear end of the clutch shaft.
They are small, and can wear out, people on here have said the PTO doesn't work right when the bushing is wornout.
The picture also shows how the splines look. I think the end of the splines may be worn in the picture. Another picture at their website shows the splines out square with the end of the shaft.
I don't have a new shaft to look at.
A man on here said in the past that his PTO wouldn't work right until he replaced the clutch shaft, and PTO clutch, that is the part that moves forward and rearward at the front of the PTO shaft. The parts had worn splines, I think.

I thought I didn’t but looks like the photo files are too big apparently to upload. its kind of hard to see but right across from the whole for the pto shaft is a piece of casting that sticks into the opening anout 1/4in too much preventing the pto lever from being reinstalled

The PTO Lever in your picture shouldn't have to be ground for it to work right. The shaft just slips into a round hole in the housing. I can't tell what the problem is in the pictures.
Can you show more.
Below is a listing at TM Tractor Parts for a new PTO Lever, I guess you know the lower pin in the picture has to be round to hold the PTO Clutch in engaged. When it is worn like yours is, the PTO Clutch can slip out of engaged.

I understand the picture is hard to see but if you look just above the transmission shaft you can see chisel marks and then look across from the pto shaft hole it looks like chisel marks as well

Below are pictures of inside Cub transmission housings. I don't have a picture of up close to the area you are asking about. Maybe you can see in these pics, if you can enlarge them some.
The 1st pic is from TM Tractor Parts.
If the housing wasn't cast right, or has extra metal in that area, maybe you can grind it away with a small grinder. Wear your safety goggles if you grind the housing.
