Repairing a Kompressor

[Dieselman]

Same principle but a different way of doing it. It's driven mechanically rather than by exhaust gas.

 

[Bobby Dazzler]

Turbocharger is a type of supercharger.

What we refer to as a supercharger (or Kompressor) is a belt driven device, with the drive being taken from the crankshaft. As there's a mechanical connection between the engine and the supercharger, there is no lag, ie boost increases with engine speed. Often there's a characteristic whine.

A turbocharger works on the same general principle of super charging but is driven by the energy otherwise wasted in the exhaust gases leaving the engine. As there's no mechanical connection boost builds, and hence there's a lag before the presence of ths supercharger is felt. Often there's a characteristic whistle.

Typically a supercharged engine - whether belt or exhaust gas driven - will produce about 50% more power and torque than the engine would produced without forced induction. However it can be tuned to provide more or less boost, and hence more or less power if required.

Great description thanks for that.

I found this info on supercharger oil, so I think I will change the oil to the correct one, I was right about the strange smell though.

I can't find anywhere in this country that sells this stuff, typical!!

I was interested to hear of your search for a suitable oil for lubricating your supercharger and found a reference to BP Turbo Oil 2380 which is used in aircraft gas turbines as an equivalent to the GM product. http://www.bp.com/liveassets/bp_int...oads_pdfs/pq/pds_bp_turbo_oil_2380_jan_05.pdf
I imagine all gas turbine aviation lubricants that meet this specification would be fine. such as Aeroshell http://www.shell.com/home/content/a...ngineoils/dir_turbineengineoils_10190915.html
which can be obtained here

and probably any airport which services aircraft gas turbines.

Supercharger oil and how to top up the W202 supercharger:

Mini?? OK.... but hey! an Eaton M45 Supercharger oil requirement is the same no matter what it is fitted to.

The Eaton M45 Supercharger uses a 'lifetime' fluid. This oil is designed to last 100K miles, but any loss of fluid by leaks or other factors can lead to supercharger failure requiring replacement of the supercharger unit. There have been some reports of higher mileage Cooper S supercharger failing due to the loss of this fluid. If you have access to your supercharger due to other work being done on your supercharger, CHECK THE FLUID LEVEL and top it off. This oil is the one recommended by Eaton. 2 BOTTLES required for complete oil change

best regards

M62 snout oil seal

Hello,

The snout oil seal on my M62 supercharger (1998 SLK 230) is leaking after 36,00 miles and I have just learned that a new unit will cost me £1850 plus fitting! My local Mercedes specialist will install a new seal provided that I can provide him with the part number or specification/dimensions for the seal. Can anyone help please?

thanks,

Cossiroger
