Part number will depend on the manufacturer. Not sure we know, as there's no reason for Solidoodle to publish this.
That said, the belts all come from SDP-SI, so I presume the pulleys do too, so with a bit of searching on their site you could probably find an identical one.

To the best of my knowledge the specs for the pulleys on the motor are:

* MXL 0.08" (2.03mm) pitch
* 18 teeth (please double-check yours though - mine are in the bottom of a box now thanks to direct drive)
* 5mm bore

(note that the pulley on the shaft has a 6mm bore - if you can't find one, you can always drill out a 5mm pulley!)

Given you're in Australia (like me!), eBay-shipped-from-China (while slow) is usually much more cost-effective than any of the usual American sites (McMasters, Misuni, SDP-SI).
I think this would work (if you count different teeth just search "mxl pulley"):

Good luck!

Hi all. need a part number on this pulley, as I've experienced a mechanical failure (probably caused between keyboard and chair). An hour + of googling and forum searching has turned up nothing.
Can anyone help an aussie out?
