We seem to be experiencing a rash of axles and cranks that don’t fit together.
I’ve never heard of this before. It’s possible that the manufacturer in Taiwan
has made a batch of hubs with spindles that are too large. Or perhaps there is a
new size for crank arms, which I doubt.
In case everybody didn’t know, when installing cotterless cranks for a unicycle,
you shoulc pound them on with a hammer before, and between, turns with a wrench
on the bolt. Don’t rely on the bolt to push the crank all the way down. This is
best done with a hard rubber mallet, and the wheel on it’s side with the pedals
off. Pound it real good.
I don’t own a rubber mallet, so I use a regular hammer and pound it carefully,
but still good & hard.
As I am currently using a 6" aluminum crank on my 26" “piece of Schwinn”, I’ve
gotten into the habit of giving the crank bolts a tighten (with the wrench)
before every ride. This has kept them nice and tight, and I’m sure they’ll out
last the axle. They outlasted the one before it…
