Update on my 49 Cub

[whtwolf97]

Just wanted to give everyone an update on how things were going with my Cub. This is what she looked like when she came off the trailer. She wasn't running, couple of flat tires, the wiring harness was ripped off the tractor, only attached at the hood support.

After replacing the coil, points and condenser, spark plugs, and fixing the wiring harness myself, I got her started. I then found out there were some oil leaks, which I have replaced the oil pan gasket, but there are still a couple of more I need to fix. The brakes were also shot. I fixed both brakes, and my wife has done most of the painting, this is what she looks like as of this past weekend.

Still a ways to go, but having a lot of fun getting there. Thanks for looking everyone, Brett

What a transformation. I like it! If you have any specific questions, don't hesitate to ask. Glad to hear of your success.

Hi,
The Cub looks Good. Just wanted to say the rear tires are directional, you have them on backwards in your 2nd picture. They don't pull good being on backwards, they spin easily, from my experience with it.
The rims come off the wheel centers, it is made to adjust to different widths. Pick a width you like, with the wheel centers dish turned in or out, and put the rims on with the tire tread pointed ahead would be better.
Here is a page from the Cub owner's manual showing the different widths.

That is nice. How much does your charge for painting?

Thanks for the nice comments everyone.

I wanted to update everyone on my Cub and ask a PTO question.

As you can see I got the tires turned the right way and I tried out my sickle mower. The mower itself worked great the problem was the PTO is jumping out of gear. It engaged and worked fine before I put the mower on it. The most it has worked with the mower is about 15-20 sec and then jumps out. I have not taken the plate off to look, but I was thinking it might be the shift clutch. Does anyone else have any ideas as to what the problem might be? Thanks

Sometimes, it is the shifter pin that slides the sleeve that engages the splines on both the main and PTO shafts. If it has a big flat on it it may not move the sleeve far enough. A bigger issue would be worn splines.

Here is the PTO shifter shaft. You can eyeball that pin by looking through the trans fill plug hole.

This thread may help you as well.
More info:
Early PTO bearings were held in place by staking the bearing into the retainer. They frequently are loose. The gap between the PTO shaft and the main shaft is supposed to be tight. Sometimes this is not the case because someone installed the front bearing in the transmission backwards. let's assume this is not what is going one here, though because the simple stuff is much easier to check and fix!

Thanks for the info, didn't know you could see that through the fill hole, will take a look and hopefully see what the problem is.

I removed the fill plug to take a look at the PTO shift collar. I tried to engage the PTO and it would not go in gear until I turned it to a certain point. Then I turned the PTO and it moved out of gear. I then turned it again to engage it and held the lever to keep it from jumping out and turned it one way then the other. As I did that, the shift collar was moving back and forth about an eighth of an inch. I let the lever go and it moved all the way back, out of gear. I did all this with the transmission in neutral. I put it in first gear and got the PTO to engage again, thinking that I would not be able to turn it, but it turned just like it did with the transmission in neutral. Should I be able to turn it with the tranny in gear? If not, is the shift collar bad? I don't know much about how the PTO works, so any help on this is appreciated, thanks

I think it's time to pull the PTO out and post some photos of what you find.

Hi,
Sorry you are having trouble with the PTO staying engaged. Something that might be making it worse, besides the wear in the parts, is the adjustment of the PTO shifter guide, they call it in the parts book. It is the part bolted on the gear shifter corner with 1 bolt. It has to be adjusted right, so the PTO shifter lever is as far to the rear as it can go when it is engaged.
Loosen the bolt that holds the guide on, should be a 1/2 inch socket, and put the PTO in gear, and turn the guide on the bolt so the lever is to the rear as much as it will go, and still work smoothly, tighten the bolt and try it, if it doesn't work back and forth smoothly, loosen the bolt and adjust it so it does.
If it is set so the lever is ahead too much in the engaged position, the PTO might disengage by itself, especially if the parts are worn some.
Here is a picture of the part from TM Tractor.

I removed the PTO shaft and found a couple of problems. First thing I noticed was this-

The end of the PTO broken off. I then took a flashlight and looked at the end of the transmission shaft and saw the broken piece of the pto in the end, I pulled it out without a problem, but I noticed that the bearing that is supposed to be at the end of the transmission shaft was broken apart, nothing holding the end of the shaft. I could see, and run a screw driver, through the hole. I found most of the pieces, I think. The pto wont be a problem to fix, just buy a new one. How do you replace that bearing? Will it go in from the back or will I have to take the tractor apart in front of the tranny to get it in? Also, does anyone know where I can get one of those bearings? I looked at Steiner, and others, I didn't see one, but maybe I was looking in the wrong place. Any help is appreciated, thanks
