Is it a bolt or a set screw with the 5/16" X 24 thread? That is real close to a metric M8 X 1.25.
I am old school, as far as inches/metrics go. Which is bigger, cm or mm?

10mm in 1cm. 100cm in a meter.

One meter = (rounded) 3 ft 4 inches

That's all I remember :D

We didn't have all that when I was in school. Never have got a handle on it.

Kenny-> Bolt...I think. The type that you actually screw into the crank with a big washer to hold pulleys on.

The new shaft is a touch shorter and I am pretty sure the set screw is gonna be right on the edge of that keyway.


Is that an inch or metric "touch"? :confuse:

Sorry, I just couldn't help myself! :smilewink:

Seriously, could you drill and re-tap the pulley further in where it sits on the shaft?

HAHAHA!! I don't think so, the belts would be off and it would rub on the engine. It is all pretty tight(metrically and stardardly speaking)...Besides, if I get the right bolt it should be fine...right?

If you don't have an industrial supply house or a Fastenall handy, try a machine shop. A 5/16 x 24 NF thread is a standard size available in grade 2, 5 and 8 hex head as well as holochrome (socket head). DON"T use grade 2.

It's a common fastener, but there isn't much call for them.
