Actually that photo is of Latemodel21's Mercedes engine. I haven't installed my bling bling pulleys yet. Still waiting for my 62mm Karmen supercharger pulley to arrive at my door. I'll post a photo of my engine bay when everything is installed. I also have some more goodies on the way from Rob at Needswings! Anxious to get the tools out again . . .

Re: 62mm SRT6 Pulley Available Now
I need a new bearing. What is the current go to bearing? Does Rudy sell them or has anyone used and verified one in 180's links?
A previous thread said the outside diameter (D) was 47mm. The internal diameter is the same as the OEM one and therefore (d) is 32mm. By my estimate the spacer washer shipped with this pulley is 5mm thick.
So we have 32mm x 47mm x 18mm. that would be Nachi #32BG04S3G-2DL available at bearingsdirect.com for $23.59.
or
NSK#32BD4718DUK available at Bearing Sourcefor $21.70
OEM SC pulley bearing.
32mm x 55mm x 23mm.
NSK #32BD45DU or 32BD45DUM, available at BearingSource for $15.40
or
Nachi #32BG05S1- 2DST
Available at bearingsdirect.com for $20.49 and Amazon at $28.53
These are double row, angular contact ball bearings grease filled for auto air conditioners.
Idler and tension pulley bearings.
Good for 15,000 rpm.
#6303DU or #6303DDU
Available at bearing-source.com
Or
For #63032RS or 6303ZZ try bearingsdirect.com
Better bearings are from the SKF range. SKF 6303-2RSL and SKF 6303-2Z, good for 17,000rpm, these bearings are sealed on both sides.
The highest RPM rated bearings (22,000rpm) are sealed on one side, SKF 6303-Z or SKF 6303-RSL if you can find them. If a bearing is sealed on one side only it is easy to clean it and repack with a suitable grease at regular intervals to get extra life out of it, the grease gets thrown out during operation. Put the seal towards the front of the car and hope that not too much crap gets around the back. Using double sealed bearings is best.
These bearings are limited by the speed that the seal can withstand. An unsealed bearing (6303) can do 22,000rpm and the fastest sealed bearing have non contact seals.
These are all single row, deep groove ball bearings, grease filled.
So we have 32mm x 47mm x 18mm. that would be Nachi #32BG04S3G-2DL available at bearingsdirect.com for $23.59.

Re: 62mm SRT6 Pulley Available Now
Not posting this to be critical of the Karmen 62mm supercharger pulley but thought those who have one might want to check it. Mine grenaded on me yesterday and the chunk of metal flew up and damaged my hood. I had less than 300 miles on the pulley . . .

Re: 62mm SRT6 Pulley Available Now
I have it's twin. Happened to me 6 months ago. Since I got mine directly from the manufacturing guy, he quickly sent me a replacement without any issues. I only put it back on 3 days ago and therefore don't have any valid feedback yet. It is hard to check for this kind of failure. This is not a rivets or a spring issue. Other than a manufacturing defect, my only suspicion is improper gap of the SC pulley itself. The gap should be 0.25mm-0.3mm. And even then, it should not fail like this.

Re: 62mm SRT6 Pulley Available Now
I got one of these from the original group buy, and I've probably got about 30,000 miles on it now. So far, no such problem. However, as I'm in the process of changing the valve cover (and breather cover) gaskets, I'm going to take a look at that today. Thanks for the head's up.
