I just took apart my opti and foun out that the screws holding the rotor on backed all the way out. Got a new base unit and i'm reusing the cap and rotor,

which way does the rotor face on the base? I have no idea which way to put it and don't want to go through the trouble and have it 180 out.

Thanks

It should have an alignment pin and only go on one way, IIRC.

 

Figured it out, the screws are off-set slightly which i didn't notice at first. It isn't keyed or doesn't have any alignment pin just to let others know. the off-set screws and the center shaft only allow it to go on one way.

Must be a non-vented opti thing. My vented opti does have an alignment pin on the rotor, plus the screws are slightly offset.
