Mercedes CLS55 AMG W219, Installing The Best Supercharger Belt, The Gates K080507RPM

Installed the best supercharger belt you can buy, the Gates RPM series. RPM standing for: Racing – Performance – Muscle.

As I am driving with a stock setup (stock supercharger pully & stock crankshaft pulley), the correct belt is the K080507RPM. I also made some comparison pictures, as I seem to have collected all the Gates belts!

  • Mercedes Benz Gates OEM / A1139970192
  • Gates Fleetrunner / 8PK1289HD
  • Gates Fleetrunner HD Green / K080510HD
  • Gates RPM / K080507RPM 8PK1289

The RPM belt seems to have the most “grippy” material.

Mercedes CLS55 AMG W219, Replacing The Crankshaft Double Pulley

After a incident in the garage, I had the idea that the crank pulley had a slight wobble. As these pulleys are known to separate (after a long period), I didnt feel comfortable with the car and made the decision to get this replaced.

Off course, its not a cheap item to replace, as this is an AMG specific item (2 belts running of the crank pulley, 1 for the accessory belt (6 ribs) and 1 for the supercharger (8 ribs)).

I went to Mercedes specialist Ralph Eidams in Brunssum where they were able to replace it within the hour, keeping down costs on labour. Even though it probably wasn’t necessary, I ultimately did it for peace of mind. I also let them replace the front main axle seal (krukaskeerring).

Mercedes CLS55 AMG W219, Upgrading To The Gates HD Fleetrunner Micro-V K080510HD 8PK1294 Supercharger Belt

It was apparent that the best in Supercharger belt would be the very popular green “Gates HD” belt, but it seems there is an even better one (more on that later).

When I ordered this belt, at the moment I thought this was the best that Gates had to offer. Its very popular as an upgrade belt and you will see it being used on many M113k engines (stock & tuned).

This belt should prevent slippage (meaning lost power) and will last a long time.

I have a stock supercharger pulley, so 1294mm is the correct belt length.




Mercedes CLS55 AMG W219, Replacing The Supercharger Idler Pulley

I noticed that the supercharger idler pulley had quite some dirt accumulation on it and also felt a bit of play, so decided to replace it with a new pulley. I made the right decision as the grease was escaping and therefore attracting the dirt.

Runs smooth again with the new pulley. When I will upgrade with billet pulleys, I will also replace the tensioner itself.

Mercedes CLS55 AMG W219, Servicing The Supercharger Oil

One of the most common overlooked service items, is replacing the supercharger oil. The gears of the supercharger spin very fast and need proper lubrication and cooling. Because it spins so fast, it requires a special type of oil: Mobil Jet Oil II (Synthetic Jet Engine Oil).

This oil is not that widely available to customers and also not very cheap. I used a 150ml syringe with some hose to extract the oil and fill it up again. It holds 150ml maximum, but you can never get all the oil out unless you remove the supercharger. I removed about 130ml, and put back the same amount in fresh oil.

Extracting the old oil
Used a plastic containter to hold the oil in, which makes it a lot easier



Mercedes CLS55 AMG W219, Bosch Intercooler Pump Upgrade

The infamous Bosch “010” upgrade pump for the watercooled supercharger circuit.

As I replaced the pump, it seems one of the previous owners already placed the Bosch 010 pump. Nevertheless a worthy replacement, as I have zero idea how old it was.

Mercedes CLS55 AMG W219, Replacing the Supercharger Pulley Bearing (Nachi)

I decided to replace the supercharger pulley bearing with a fresh new Japan made Nachi bearing. One of the easiest way is the hot/cold method, where you heat up the pulley and freeze the bearing itself. This results in the bearing sliding into the pulley with relative ease.

I could’ve also used my workshop press, but I didn’t want to force it in. I followed this guide for it:

Mini Cooper S R53 JCW – Servicing the Eaton M45 supercharger

When I bought the Mini, it had reached the 160.000km or 100.000 miles mark. This is a milestone in the Mini Cooper S service history, because it means that you need to service the Eaton M45 supercharger (new fresh supercharger oil etc etc).

I saw the episode from Wheeler Dealers and felt confident. It was a lot of work, but fortunately it wasn’t complex. As this isn’t my daily driver, I meant I could take the time.

Mini Cooper S R53 JCW – Vacuum Gain System VGS Modification

As usual, the Mini Cooper S with the Eaton M45 supercharger also has a bypass valve, which helps with fuel economy and lighten the load on the supercharger during idling (for instance). On NAM (North American Motoring forum) I noticed a popular mod, which is also known as the VGS or Vacuum Gain System modification.

Basically, the VGS mod changes the way the Bypass valve is operated. From indirect vacuum to direct vacuum, allowing faster response of the butterfly valve, but also keeping it shut better so no boost is lost.

I liked it in the beginning, but it makes for a rough driving experience. So in the end I reverted and never went back. Thats why we experiment 🙂
