This is in relation to certain events that have tainted my trust in C3, which is now with LET. So now I start wondering if my s/c pulley is really that great or was it just produced for a quick profit? Its been nothing but great for me but we all have a right to wonder about the R&D and endurance of it due to recent events.

So don't read into this thread thinking my C3 pulley bearing is bad. Its not, yet. This is for safety precaution.

Wouldn't it be nice to have a bearing replacement just in case? Has anyone researched this yet?

 

Code 3 offers replacements on their site. I believe the bearing Code 3 offers in their pulley and for replacement are both NSK which are high quality. I think the stock bearing might also be NSK.

 

I ll try to find a book number, I have a code 3 and plan to use it on the 178 that I have, WOODY ENJOY

 

Ho Ho Ho
My code 3 bearing is a NSK and it reads 326045DU. Its off till I get a tune as Iam hitting 17 A/F ratio above 20 PSIG on the data logger with the 178 pulley, yuckki Note to self: Stop experimenting and pull-out ECU and send it

THe bearing is about 31.85 ID and the bearing surface is 24 mm deep. I tried to pop it out and got the c clip off but didnt wanna hammer anything, so to speak. Hope that helps you, WOODY

 

Thanks Woody. Are you saying its safe to hammer a bearing out and what, hammer one back in? Or should only a bearing press be used? Just curious....

 

Press please!
If you must "hammer" be sure to not hit the pulley. Use a block of wood or something between the pulley and hammer.
If you don't have a press a C-clamp would work.

 

I added comments but I was in error.

 

So I contacted NSK. They said they have no record of Woody's bearing number Strange... My Code3 pulley has a 'flutter' sound while driving, I confirmed this by removing the belt and spinning the pulley as best I could. I'd like to have a replacement. Hmmmm.

 

are you sure it is not where the pulley is rubbing on the magnetic clutch? You can see it if you turn it slowly, i doubt that will hurt anything.

 

I apologize for the delay, been fixing several problems and developing new Mods for the srt, they will be available soon enough, stay tuned.

The code 3 pulley bearing reads 32BD45DU.

I glansed at the bearing and now pulled out the microscope to get closer on the NSK bearing. Hope that is of value to yall.....

Woody BE HAPPY

 

Ok bearing experts. What are Air Conditioning Bearings? Sounds like there's an air gap some where that reduces friction, thus heat on these types of bearings. Found this site when Googling Woody's part number. Be sweet if it would work for us.

I thought the Code3 pulley used the same size bearing as the stock S/C pulley?

Can anyone with a Code3 pulley check the bearing part number on factory pulley?

The bearing ID must be the same (to fit on the S/C shaft), and I doubt a thinner bearing would have worked, so reducing the bearings OD would only reduce the size of the ball bearings...thus spin the Code3 bearing faster at (compared to factory) at each RPM level multiplied by increased S/C RPM of the reduced pulley size.....

And I thought the Idler pulley bearing was being maxed out.....

Does MB offer a replacement bearing for the stock S/C? Perhaps Ed Martinez @ PSE superchargers offers one? - PSE offers a 100% refurbished S/C for our engine so they must replace the S/C bearing in the process....

 

Interesting, the stock bearing is the same size? Hmmm.... Anyone have confirmation of that?

I was hoping a google of 32BD45DU would bring up a magical page to buy it at, but no luck...

And Brian, about the idler pulley being maxed out, that doesn't happen with the Code3, because it doesnt affect the spin-rate of the idler pulley.

 

If I’m not mistaken, the supercharger’s clutch bearing becomes essentially solid on its shaft - with no rotation between its inner and outer portions – when it’s electromagnetically engaged.

Nonetheless, C3P/Brandon has stated on numerous occasions that his pulley uses an OE-sized bearing.

MB offers a replacement bearing only with their complete clutch/pulley assembly.

 

You know some times, these girls can really amaze you. I am out of town but my better half reports that the stock bearing is 32BD45DUM1 on it and the Code 3 has 32BD45DU on it. I asked her if she was sure about that and she replied....the one in my hand has the "extra M1" on it and the one on your car does not. Well the Code 3 is in fact installed so there you go.

Not sure what the extra "M1" means though.....

 

Air bearings can be the type that go under a load and compressed air over a large area is used to lift the load on a layer of air, like hover craft.

Another air bearing uses the high speed of the spindle to rotate vanes that draw air between the surfaces. These bearings have to have a balanced load on the shaft like fan or turbine blades. The load cannot be on one side as the shaft will be pulled to that side and cause friction.

Bearings that have odd numbers on them and cannot be traced are often bearings that are made specially for a manufacturer. They may be a standard bearing size that may or not have special features like seals or sizes. The manufacturer would often like you to buy them from him at a higher price even though it is an off the shelf item. $$$

 

oooo good info. So that suggests they really are the same size....

 

oh, i guess we shouldnt ignore the 2 page post at mbworld with part numbers in it http://www.mbworld.org/forums/c32-am...s-video-2.html

unfortunately none of the part numbers seem easily buyable

 

This last post might help. Let us know if it works.

To get to the point, it looks like 32BG05S1-2DST is the Nachi substitute for the DAC32550023, which is again a substitute for the OEM NSK 32BD45. I was able to find it at bearingsdirect.com, and wanted to share the wealth. If nothing else, seems to be another source. Once I verify tomorrow I'll let you know how ordering / installation / lifespan goes.[/

 

As usual Splinter is spot on, for the most part the s/c bearing has an easy life. Woody Be Happy
