OK!!, I`ll bite. What is that "Reese" thing you are using that you added "Thanks" too

Reese makes trailer hitches and receivers for automobiles/trucks. Looks like Donny used a Reese ball hitch to push the crank pulley back on the crank.
The threaded rod goes through the hole in the hitch where the hitch pin would normally go. GREAT thinking, Donny

Bud, Now with your help i recognize the Reese name on trailer tongue parts. That one Donny is using sure looks short to be a stinger for a receiver hitch if in fact that is what it is. Looks like a nut on bottom for ball attachment in picture though. Although unimportant I thought I would clutter up this post with trivial questions. "Ho-Hum"!!!

Yep, does look a little short.
Donny will post soon and let us know exactly what it is he used.

Bud & JB,
You're both right
It's an adjustable height receiver hitch. Maybe this will clear things up.
Sorry for the confusion

How did things look when you hooked up that osilloscope to your cub
Did you replace the front oil seal, and use a speedy sleeve?
I guess the heat is not enough to hurt the seal?

That's a Network Analyzer in the back ground. (nothing to do with Cubs, sorry) As for the heat and the seal only time will tell but that's why I only heated it up to 220. I did replace the seal but did not use a speedy sleeve, the pulley showed no signs of wear whatsoever. I did test fit the seal to make sure and it was nice and tight. I was amazed considering the condition of the rest of the tractor.

Looks like you are making progress on your tractor. I just got mine from
the machine shop yesterday minus the head. I will soon start putting it
CUB BUD and I were having the same discussion about heating the pulley
as he was driving his dad's back on with a big block of wood. I have seen
where some said they heated to 345 deg F. Looks to me like that would
damage the oil seal. I was even considering doing mine that way until
I saw BUD drive his on cold.

At 220 degrees, you are barely hot enough to boil the water in the radiator. Operating temperature of much of the engine is well above that.
Here is a site with some operating temperatures that I think are pretty conservative. The lowest they quote is Nitrile at 225.

The Nitrile or Buna-N is the same compound that most black "O" rings are made of. I think I was pretty safe by only heating the pulley to 220 as it cools somewhat before it makes contact with the seal. The crank makes a good heat sink.
I also think that the 225 number is a little conservative.
