Frozen cam lock nut

[Bernhard]

Just started restoration on a 1962 cb77. Motor was in a flood 40 years ago. Any thoughts?

If engine was submerged in water then it may have rusted on, you will almost need some heat (depends on how much it has rusted) as well as penetrating fluid Try using shock tactics, that is hitting the bolt with a soft alloy drift and hammer-then using an 8 sided socket –not a muti-corner type or you will round off the bolt edges- sharp taps with a hammer in both, opposite directions at first, then correct direction to loosen it

Cam nut loosened and cam removed! Thanks for the great advice, but I did not use heat. This nut still has me confused. Does it tighten towards the cam to lock into place (i.e. away from the cam sprocket)?

To the middle of the engine. (into the sprocket). ..lm
