OEM 74mm v Code3 Pulley Bearing Diameters
 

Just checking before moving to replace both my bearings.
Does the 32BD45DUM service both the OEM 74mm and Code3 65mm pulleys?

Re: OEM 74mm v Code3 Pulley Bearing Diameters
 

yes, C3 uses the same size as OEM pulley. Just changed them on both of mine.


Also, mine is up for sale in the parts section if anyone is looking for one!

You mention an alternate bearing - for the "poor mans belt wrap pulley" rated to 18,000rpm

Given I'm moving towards 178+65C3, I'm Just trying to get my head around the function of the pulley bearing before I swap it.
My understanding is that the SC pulley bearing is only called upon the do its job when the supercharger is not engaged by the clutch. Given that such a case at high rpm is only going to happen on the very odd occasion of an a ECU trip on high AIT or similar = disengage SC clutch = a high speed bearing is not essential in this particular case....sound fair or am I totally a$$ about.

Those are for all the other pulleys. I don't know of a better alternate for the S/C pulley... and as you said, it technically should be magnetically locked to the clutch mot of the time.
