"Pip pin" is correct. "Axel" is not. An "axle" is a shaft used to locate and contain a rotating mechanism.

An "axel" is a jump in skating with a forward takeoff from the forward outside edge of one skate to the backward outside edge of the other, with one and a half turns in the air.

And you probably installed a cotter pin, not a pip pin.

Just sayin'

Next time on the ice , will try that; this must be the root of the word axeleration,
meaning speeding up rotation.
