I'm posting this on behalf of a friend who lives too far for me to view. He has the Hogs head off and is in the process of relining his bands and found this.
Causes and fix ideas would be appreciated.

Re: Clutch Fork, what would cause this problem?
The hose clamp was probably put on the shaft in a failed attempt to prevent the shaft from pushing too hard to one side.
Several things can cause the shaft to push to one side or the other. Bent. worn, or otherwise damaged clutch cam, levers, or linkages can put quite a lot of pressure one way or the other.
Simply installing the linkage between the low pedal and clutch shaft can put quite a bit of pressure. Another cause can be not having the matching offset (starter and non-starter) pedal and clutch shaft.
The "L" and "fork" link between the pedal and clutch shaft arm can often be flipped around to improve lining them up a bit. Sometimes arms need to be bent to get them near right.

Re: Clutch Fork, what would cause this problem?
I"d be checking to see if the rivets holding each arm are tight. It looks like on is loose on the shaft, allowing / making the other

Re: Clutch Fork, what would cause this problem?
Some aftermarket clutch packs ( early Watts perhaps) were sold many years ago with a round wire high speed clutch spring from a modern automatic transmission (Buick?) that was just a tad bit too large in diameter and those would rub on the clutch fork arms. Just something to check.

If he has a spring, washer, and o ring on the outside to “seal” the shaft, that is what caused it.

Re: Clutch Fork, what would cause this problem?
I missed the hose clamp when I looked. It may well have been fitted to mask a problem. The L linkage between the clutch shaft and the pedal can cause unnecessary load, especially if the eyes have been rebuilt and drilled back to size to neatly fit a new linkage. The pedal needs to move sideways when operated. A neatly fitted L linkage will not allow it to do so without adding tension within the system. It is one place where absolute precision works against you. There needs to be a little 'slop' to allow the pedal to move sideways.
