Frozen cam lock nut

[Husker45]

Just started restoration on a 1962 cb77. Motor was in a flood 40 years ago. Managed to get rockers removed after some effort, but cannot get the cam lock nut to break loose. Followed all advice on the forum, but to no avail. Any thoughts?

First off if you didn't remember it has left hand treads. I would saturate the treads with PB Blaster each day until I was able to get it loose. Hope this helps, also could you include your location. Cliff

I remember the left-hand threads, but to be sure that would be when looking from the point cam end correct? From that direction the nut would turn clockwise to loosen right?

+1 on the PB Blaster - make sure it's the penetrant, not the lubricant; and yes clockwise from the points cam end will loosen it. Wedge a piece of wood between the sprocket and the casting to hold it still, then I would shock it with a big screwdriver and dead-blow hammer on the nut. Don't use any heat because the advance weights have some rubber stoppers on them. You will eventually win...

some of them, (the early ones) are right hand threads!

R is correct about the early ones being a normal thread.
If yours (1962) has the BIG WEIGHTS at the Center the thread will be normal.
I have had 4 of the usual looking ones that had normal threads so ya may want to try counter clockwise. . ............lm
