M113K 'charger - replacement or rebuild required

[Celicasaur]

Hey guys, the supercharger on my E55K seems to be on it's way out. It's doing the dreaded continual squeak - we suspect it's the rear bearings that apparently are unserviceable according to what the interweb has told me in the past, but perhaps things might have changed in recent years that I'm not aware of. Is it possible to get these units rebuilt with a fresh lease of life, or is my best bet to source a used one from eBay or a breaker? FYI it's not the front pulley bearing and that's been recently replaced anyway.

And no, I don't want to take this as an opportunity to get a Weistec upgrade

I think you might need to go down the second hand route buddy? Found one on ebay, not sure if this is of any help? I think there are 2 types, slightly different gearing. Parts numbers A113 090 0580 earlier, A113 080 0280 later

These guys managed to take the supercharger apart, I don't understand their language but I think you may be able to interchange the good parts around, given the ones on ebay seen better days. Try also mercedes dismantlers to

Thanks guys

Hmm seems like a bit of a fruitless one, this. I might well have to just bite the bullet and buy a good (but ultimately tired) unit from eBay Germany.

Ditch the supercharger and go twin turbo

And, the rear bearings are clearly visible and undoubtedly replaceable - assuming they are commercially available (highly probable).
The only 'difficulty' I see is in supporting the bearing housing during removal and re-fitting. Pre-heating (moderate temp) will help (massively).

Mine failed 2 years ago and the part is no longer made so had to find a used one too.
