I think that video stabilization in google/YouTube video processing is happening. The tire tread is shaking side to side .. but look stationary in the video.

Well, sheave is on in what I feel is the correct way ... im not sure if I have the belt too tight

How much "shaking" can a generator take?

My other knew what I was going to put in the deep freeze ...

Shaft hit 20deg and bearing was heated to 200 degrees in a shallow oil bath ... for a 180deg differential

Slid right on ... I even put the lock tab and nut quickly and tightened

Sandblasted

To be honest, I think that nut is still good enough to go again. Once torqued up using the C spanner you only need to fold a tab over to lock it in place. If you do not have a C spanner they are so easy to make by tracing the outline of the nut onto paper and thi gives you the pattern. Then enough 3/16" piece of sheet steel and a cutter and a file and then a length of pipe on the end of a short handle.

I had to use 2 24" pipe wrenches to get it off.. and was hard to turn until it came off ...
I need to find out what size/threat it was to get it to a point that i can finger thread it on .. and use the lock washer to keep it from coming off.

I have not sourced a new nut yet ... but probably should

2 x 24" pipe wrenches with cheaters ... and it fought every mm of the way

The lock ring ( the thing with the fingers ) is still playable

The Nut ( I still think it's a nut ) is still stuck ... I know I have 2 24" pipe wrench,  but currently can only find one.

So tried with a large set of vicegrips and one pipe wrench ... no movement yet. So I put some heat to the nut again and sprayed it with penetration oil ... then walked away.

I dont want to cut it off ... it might be a pain finding a replacement nut with the head still unknown to me as to who made the darn thing.
