Squeeky underdrive pulley

[pigsti]

I thought it might have been the belts, so I replaced those, but there still seems to be some squeekyness coming from the underdrive pulley. I shot some WD back there and that seemed to help , but only for a really short while.

Can an underdrive pulley go bad?

i don't think a pulley can really go bad, is it tight? the wd makes me wonder what would be squeaking..... timing belt been done?

The pulley is glazed over and needs to roughed up with sand paper

what precisely needs to be roughed up? Its a perrin .....Timing belt was done about a year ago , included all the gears

Take your belts off start the motor and run some sand paper on the belt surface it is squeaky cause the surface has become to polished and smooth
