782 lift stop cam

rw93cobra · #1 08-31-2011, 03:43 PM

My 782 was missing the lift stop cam and knob when I got the tractor. I bought a cam and knob, but the threaded part that the knob threads into is missing on the frame. I've searched all over the internet, and couldn't find a new piece to weld onto the frame other than cutting it out of a junk frame. Does anyone know if anyone sells a new threaded piece or should I get it off a junk frame?

You could weld a nut on the inside of the frame. Makes me wonder how it got missing? Got a pic of it inside of the frame?

Or take a heavy wall thick bushing that has approximately the hole size needed (if not drill it if need be) and tap it to fit the threads on the lift stop cam knob then drill a hole in the current frame weld the bushing on the back in the proper location shot some paint on it. It'll look factory.

That's what I would do.

I'm sure someone with a 782 that has the lift stop cam would be more then happy to get you dimensions on the exact location of that hole to be drilled in the frame.

I broke mine off on my 1811. The rockshaft was frozen from rust and I thought I could just put something against it and work the lift. I was wrong. It bent the bolt and broke the spot welded thread insert. I put a nut and bolt there for now. Once I set it I don't need to ajust it so I'll get around to fixing it someday.
It took me over a week, a can of PB and Kroil with a 3' steel shaft and a sledge hammer to free it up. That was one of the hardest repairs I had to do yet.

When I got my 782 the threads on the frame were shot too. Its been a long time since I repaired it but this is what I remember doing.

1. The threaded piece with the threads was tacked on so I remove it.

2. A nut with the correct threads would just fit in the hole but I needed a way to hold it straight while I welded it on the inside.

3. I took a piece of angle iron and drilled a hole and using a bolt with nuts on both sides mounted it on the angle iron.

4. Put the nut on the flat side of the angle iron in the hole in the frame and clamped the angle iron to the outside frame.

5. Welded the nut on the inside of the frame.

6. Removed the bolt and angle iron and welded the nut on the outside of the frame.

7. Ground the weld flush on the outside of the frame and painted it.

8. Still working good years later.

Yea I would weld a flange nut inside the frame a place here has them for a quarter, other possiblitys are weld the hole then redrill an tap it . -mine was froze but freed up . now if I ever get the lift lever free I'll be all set.

I agree with the others, weld a nut to the inside if the frame. A flanged nut would make it easier, and I couldn't quite understand the post about clamping it on prior to welding....I would hold it in place by tightening down the adjusting cam handle, that would hold it in place to weld it in.

I dont know if this will help anyone. But i tried to fix my 782 properly. The thread insert in the frame was cracked. It appeared to be bent and i thought it was just an insert that would press out.
I took a hammer and tapped. It flew right out. After picking it up i realized it was cast iron. And also welded in.
So after i completely destroyed it in one tap. It was already broke so thats probably why. I decided i better fix it right. I only have a very small lathe so making the part would be hard without a lathe twice the size of mine.
I was thinking about what i could buy that may already be close. It has a taper so the lift stop cam will hold tight with little effort tightening the bolt. I wanted to keep that taper.
Just simply welding a nut inside the frame was not going to be good enough for me. Plus it would scratch the frame unless you put a washer between.
I thought about it for two days and it hit me, A LUG NUT !!!. It has the taper already. So i ordered a pack of painted steel lug nuts in 3/8 fine thread. I sanded off the paint, cleaned the hole well on the frame.
Before welding it in, i used some valve lapping compound to properly mate the two taper surfaces. This gives it much better grip with very little effort tightening the bolt.
I then screwed the lug nut, cam, and hand screw all together. Placed a temporary washer between the frame and cam to keep even spacing. Then welded it on the inside of the frame. Fits very nice and has the original gap between the frame and cam.
I hope this helps someone that stumbles across this.

Now im almost ready to start painting the frame. For the 100 percent full restoration i am doing.
