The number stamped on the part is 11287807021; BMW's catalog files it under the short number 7807021. You will find it on our Engine shelf, under Other Engine parts. It supersedes the older number 7786881, so a part carrying that number is the same part.
It fits every E46 body style (318d, 318td, 320d, 320td and 330d, 2001–2005), with the M47N or M57N engines.
BMW draws it on 2 diagrams, among them Belt Drive Water Pump/Alternator (11_3316) and Belt Drive Water Pump/Alternator (11_3461). It weighs about 390 g (0.9 lb). It also comes in BMW kits Set, belt drive, water pump, alternator (2339099) and Set, belt drive, water pump, alternator (2339100) and 4 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
