m113 supercharger bearing

[DavidL]

I've had one of these on my shopping list for a while now so I need to get one ordered.
I'd have a smaller pulley but I don't really have time to have it set up properly and I don't really have any need for it to go faster!
So I assume the bearing and a pulley bearing are the same thing?
There seem to be 2 options.
Genuine Nachi ones either from the US
45BG07S5A1G-2DL NACHI Supercharger Bearing Made in Japan Mercedes C55,CL55,S55 | eBay
or from Estonia

You can get these from the Philippines too it seems.

but there seems to be some vaguery about custom charges

or a pattern part also from Estonia.

Neither are a lot so I'd stick to the Nachi ones.
But are there no UK stockists?

Anyway I think the Nachi one for 60 bucks from Estonia with no import charges and free shipping seems the best option.

Anyone done it?

Hi David, Yes i have what would you like to know?

Is it an easy job?

I can hear a rattling noise on the rear of my supercharger, performance not affected

 

[DaveE320CDI]

When you say the rear of the supercharger do you mean the opposite end to the pulley?

 

[DavidL]

Hi David, Yes i have what would you like to know?

Mainly which bearing you chose and why. I won't be doing it but from the video it didn't look that hard.

Lol ignore - I was referring to the two internal bearings at the rear of the supercharger....

 

[DaveE320CDI]

Hi David, Yes that video more or less shows how to sort it, as far as the bearing choice i went for Nachi which is supposed to be OEM fitment, i think that they have updated the oil seal on the later bearings from orange seal to a black seal, no change to the bearing just the seal,

Thanks. I went for the Estonian one in the end, same thing but a bit cheaper. I'm not doing it but I know a man who can!

Just quoted £53.64 plus delivery for Nachi 45BG07S5A1G-2DL from simplybearings.co.uk

Is that the correct part for the 77mm pulley?

 

[Alps]

bearings should be the same for all the pulley range, yours is fitted with a 83mm one btw

Well spotted, that reminds me of something I found in my garage yesterday, must go to post office.
