Default Original IMS bearing!

Does anyone know the OEM part number for the IMS bearing? I just had mine done and noticed on the old one that it was made in Japan, so I started to wonder if it was the original or not. The numbers it has on it are 6204dua17, bd20-17, NSK, and 058. The shop I had it done at said it is perfectly fine, it almost looks like its brand new even. My car is an 01 C2 with 101k miles and in all the records I have on it from before I owned it there is no record of replacement.

If its the original I'm just surprised how new it looks after 101k miles. I actually thought the mechanic was handing me the new one that they had ordered in when I went to pick up the car.
Krazy - I replaced it with the LN bearing

Thats a dual row bearing pictured. These bearings were specifically manufactured for Porsche with their internal snap ring.

Before you grade that bearing remove the seals and wash the lubricant from it. You'll see that the bearing changes a lot when this is done.

Ofcourse it does, the metal cage bounces off the spinning ***** and now being dry, it makes one heck of a racket.

I saw my old car 2 weeks ago after I had lost track of it for a couple years - the "new owner" had it about a year and was ecstatic to meet me since I had done most of the mods on the car - when the topic of IMS came up - we determined it must still be the original one and the car is sitting at 150k miles now

so - yea, it can happen

Why did you decide to have the IMS done? Was your VIN # a known bad #? Premptive?

Yes my VIN was on the list but I had an RMS leak so figured I might as well have the LN bearing installed while in there. Also just for peace of mind.

I think most who retrofited found their orginal bearings were in good to great condition. I have only seen one at most two posts saying otherwise.

Since my car is a Tip, it is rather difficult to drop the engine for "while you are in there to replace the clutch" syndrome to replace the bearing, that said, for peace of mind, I would not mind spending the extra money to replace the IMS bearing for peace of mind even though I am finding out more often that those who replace them claim that the one originally installed seemed to be fine (nobody has claimed to open them up an see how what real conditions are behind the seal....). Congrats and glad to see that 90+% of the engines are like yours, hence my decision to get another 996.
