Refurbish kits
I'm thinking of doing a complete tear-down and refurb of all the bearings and seals. So it would be good to know the OE supplier and various part numbers.
Anybody know?

Thanks for that link.
I also found on Wiki link on the "Kompressor" "55" engines (M113K) that mentioned that IHI is the vendor.
So now I am searching for seals and bearings that can refurb the IHI unit.
Here are some of the salient points on the Wiki:
"...with a highly efficient Lysholm type twin screw supercharger and water-to-air intercooler. The supercharger was developed in conjunction with IHI and features Teflon-coated rotors, is found in the rest of the AMG 55 models which are typically midsized or larger vehicles. The published output according to Mercedes varies from 476 PS (350 kW; 469 hp) to 517 PS (380 kW; 510 hp) and 700 N·m (520 lb·ft) to 720 N·m (530 lb·ft), depending on various methods of power measurements and different ECU programming for national legislations. For instance, the E55 AMG's engine was at the low end, nonetheless it was still Mercedes-Benz's fastest sedan at the time,[13] while the SL55 AMG's engine had the top output.[14][15] Mercedes has claimed that a more restrictive exhaust system was responsible for cutting output on the E55 AMG, however some enthusiasts have managed to bump up horsepower to 505 on the E55 by incorporating some parts from the SL55.[16]
The supercharged 5.4 L 24 valve V8 engine was mated to the Speedshift 5-speed automatic transmission, which has a torque capacity of 796 lb·ft (1,079 N·m), as the newer 7G-Tronic introduced in 2003 is limited to 542 lb·ft (735 N·m), not enough to handle the torque from the supercharged V8.[17][18]"
