Anyone know how the pulley is attached to the motor shaft? I didn't see a setscrew.

Also, what does the curvature of the pulley do...keep the belt from jumping off during startup?

Thank you

AFAIK, most if not all Linn motor pulley is press fit to permanent. There's no setscrew. Removal may require the use of a hot air gun and very careful process to remove.

Default linn axis repair

Thank you for the capacitor list. Could you (or anyone who can be sure from the top photo ) possibly also specify the axial length, and radial diameter & lead spacing? I need to order the right parts from mouser.com (unless you have a better suggestion) for my technician, before he gets in there to see the actual sizes. A catch-22 I know. Would be GREATELY appreciated!
(2) 33uF 350V axial (250V ok)
(2) 47uF 250v axial
(2) 220uF 16V axial (long-lead radial will do if axial unavailable)
(7) 22uF 50V radial

Not too familiar with Linn, Iím more of an Ariston guy, but if Iím not mistaken, the curvature keeps the belt centered on the pulley.
