FAO: Gizmo - e36 328i pulleys

[Doomsdaya]

As discussed, bmw wasn't very helpful when it came to diagrams, there's like 3 different types for my car, will you be able to tell the two pulley part numbers from these pics ?

Tensioner pulley, common part for both belts, iirc BMW want to sell you the entire new tensioner, not just the pulley?

Not really, according to the diagrams below, the guy wasn't sure which two I need for my car, but if you say they both the same, then I would need 2 of the same part No.5 in the third diagram right ?

one pulley runs both belts................

If you enter your last 7 digits of your vin into realoem it will show you which parts are applicable to your car.

I hope the dealers asked you for the vin too?

As in this pic, there are 2 different pulleys, one of which has an off centre hole : no 15

The other looks like this :

Yip thats the reason for the guy's confusion, even if I enter my vin number on Real OEM & at Bmw, those 2 different types of diagrams appear. None the less I bought two of the same as your last pic as my engine doesn't have that off-center pulley

The first two parts diagrams you posted are for the main V-belt (running the waterpump, P/S, and alternator) and the last diagram is for the Aircon compressor.

So if you are looking at the tensioner/pulley for the main v-belt, there can only be two types. 1 tensioner using a damper to provide the tension and the other using a coiled spring to provide tension. It should be quite easy to identify which tensioning system your car has. If you can see a little damper then it is naturally the damper system. The pulley used would obviously depend on the tensioning system used, as both pulleys look the same but have small differences. All 4 of my e36 328i's had the damper type tensioner for the main v-belt and spring type for the A/C compressor.

That pulley with the off centre hole is actually a deflection pulley and is seperate from the tensioner pulley/system. The bolt that secures it also acts as a fastner for one of the alternator brackets if I remember correctly.
