1340 breather gear won’t move at all

Sorry, wrist pin, not crank pin. I recall it was a shovelhead. Somehow or other, the button wore down and then the wrist pin walked out into the cylinder wall. Whoever's motor it was didn't have a lot of money and just rode it like that, making noise and smoke, until the gouge in the wall was really deep. I seem to recall it was almost through the cylinder at that point.

There is more to that story than you were made privy to..

Happened to my dad's '81 fx or fxe (can;t remember for sure) - was a hell of a mess

No it isn't.
The OP said his breather gear was locked up but the fix was the wrist pin clip replacement. AND he pulled some metal out of the engine. When my motor ate itself last summer there was damage to the crankshaft bearings from metal shards.
Just sayin

Cranks twisted enough it forces the wrist pins to walk hard to one side, haven't run across many buttons outside race motors but every engine I've seen with a clip or pin into the cylinder walls the cranks had a visible tweak to them, runout on the shafts were crazy.

That and I know exactly how the Bottom end effects the wrist pin... but... still contend the Assembler [certainly not a mechanic] causes this far more than bottom ends do.... Like putting a Spirolock where a circlip belongs...Pistons have a Specific keeper they are designed for...
