Over the weekend i went to get a tune, on the second to last pass we noticed smoke coming from the bay. Next thing we know, the pulley and blower is seized, we checked the oil and it was very low but still a little.

Decided to take the blower off my car to check it out tonight


This is what i found.


The shavings aren't metal, they feel more like rubber. Blower won't spin as well, anyone have an idea why?
Don't want to disassemble the blower, just incase it voids warranty.

 

Dun dun dun, another one bites the dust

 

Not sure if this is the same thing ... but when my blower went, we noticed the following when taking it off:



This was a collection of the "rubber" that was found.

 

Was the blower primed with oil and then checked at low speed to ensure that the oil was circulating properly per the Rotrex instructions before taking it to the dyno?

 

^This. Was this the C38-81 or -91 blower?

 

Was very sad to hear about this Hopefully we can get it resolved with Kraftwerks soon so you can get your car back on the road

 

What was the verdict on the cause of failure?

 

Yea the rubber shavings were like that! Did you ever find the cause or solution?

 

Yes we used pressurized air to circulate the oil, then started the car with low revs and it seemed okay.

c38-91 blower

 

What's with all the galling on the pulley face and blower hub face? It looks like the pulley was moving against the blower hub for quite a while.

Rubber shavings almost have to be from the belt. I don't think a bearing seal would be able to leave that much material behind.
