slk200 2004 eaton supercharger - looking for a spring

[zeusthegreatest]

i've struck a problem and looking for international help! my manual slk200 dec2004 with about 80000 km lost the kick and the engine light came up and a little noise appeared. i took it to the mechanics straight away. after being quoted an 8 hour labor to remove and refit the supercharger (as the 'doctors' determined the noise coming of it) and a few days later waiting for really bad news, i was told a spring had broke and there is no further damage to supercharger. how wrong was i to think i have no issues?? i cannot find the spring!!!! merc only sells the complete supercharger for $5300AU!!! the only eaton distributor here only sells the part where the spring is (part number 307929 - 29DCB BEARING SPACER or i've seen it called the pulley) for $1000!!! and all i need is a $4 spring!!! does anyone else have/had same issue and can direct me elsewhere?? i've contacted eaton contact for the part in cleveland (as per there website) and they said the spring is not sold as a part.. so why on earth did it break and why should i pay $1000 for something i don;t need??? i'm attaching some photos of the part and the spring and desperately hoping someone can advise what to do /where to go. someone local suggested to find a company to make me the spring.. but i am really worried to put a non-eaton part and have more issues later on. advise? opinion? i would pay whatever to get the spring wherever in the world! thanks in advance and very happy holiday to all!

I'm not an expert, but that looks like a clutch type spring, - i.e. it will allow something to freewheel in one direction, but lock up and transmit drive in the other direction.
That suggests that you MUST get the correct part.

Hope you get it sorted (and cheaply)

There is a company here in Greece claiming to have the original spring for about 200 pounds and another distributor who has constructed it by himself!
For the 2nd case the spring was fitted in a 2380 supercharger and lasted for about 3 months!

I would advice you to start looking for a supercharger
