I sloppily removed the clutch contraption, apparently without

functional damage to the grass trimmer.



I need to attach a 1/4 inch aluminum rod to that threaded bolt

sticking out from the crankshaft. Looks like it uses an uncommon

5/16"-20 bolt.



Any common or easy to get small plastic or metal parts threaded

5/16"-20?



A workaround (see the picture)...



I suppose some plastic or aluminum could be stuck over the bolt

and glued onto the base. And then the trimmer could be started and

used like a lathe to cut a hole for the 1/4 inch aluminum rod that

it will drive. That assumes the base is sturdy enough to twist the

rod. If so, maybe the bolt could be cut off to reduce the depth of

the additional material.



Apparently the shiny metal piece stuck on the black plastic is

used for timing the engine. With the opposite side of that metal

piece being there for a counterbalance. That's my guess.



Thanks.
