Vortech V3 failure
 

If you don't want your oil slinger to look like this, don't over spin your V3. :rofl2:

Oh my! Is this yours?

My old one. The V3's don't like to be over spun I found out. I always thought the bearings failed from over spinning. Come to find out it's the oil slinger. They're just laser tack welded on to the shaft and the welds break under really high rpm. It then starts slinging itself. :rofl2:

😳😳😳😳

Yes but define "overspun". I know you are going into warp mode with yours. Lets not confuse guys in thinking taking it up a few K past limit is going to result in catastrophic melt down.

They're rated at 52000 rpm. Vortech used to state that they could be run up to 55000 safely. They have since retracted that and they recommend that they not exceed the 52000 rpm limit.

What's the slinger made of? Brass or steel? What I found with the brass slingers on other equipment. Is that if they get a worn spot on the inside. When the equipment stops and the slinger comes to rest. If it rests on that worn spot. When the equipment is restarted. The slinger will NOT spin with the shaft. The other thing is if the slinger is out of round. The same thing happens. With either brass or steel.

I'm pretty sure it's steel, I'm not sure if it's stainless. It's basically tack welded to the shaft. The oil slinger is their most common failure point.

Never seen one that's tack welded to the shaft. :icon14: You sure it didn't weld it's self to the shaft?

Straight from the email I received from vortech. I then talked to another shop that verified it.

"The gear sets are matched sets, the oil slinger is welded to the shaft, so it can’t just be replaced by itself"

Meh. Jar will still buy it if you post it in the for sale section.

Nothing a little JB Weld can't fix. ;) I'll post it up when vortech sends my blower back. Probably have a couple bad bearings he might be interested in also :tup:

But weren't you taking yours to like 72,000?

62700. But still way over what it was rated for. The only reason I pushed it that hard was because I had the upgraded 928 ceramic bearings and I thought the bearings were what failed at high rpm. If I had known that it was the oil slinger that's prone to failure at high rpm, I wouldn't have spun it so fast (well, I might have anyway) :rofl2:

Ok, I see that it uses a disc instead of a ring. From the pictures I've seen. It looks like the disc distorts at high rpm. Then it makes contact, destroying it's self.
