Does anyone know the specs on the aircondition pulley belt for the S50B30?

I need to replace mine but I cant find the measurement for the belt.

Do you have the emissions pump installed, or no?

I'm not sure what the emission pump is. Can you enlighten me?

I don't know if your 3.0 has it (3.2's do), but it's a pump located between the block and below the AC compressor. Basically if you have it, check to see if there are 4 pulleys riding the AC belt (compressor, crank, tensioner, and emissions pump).

Once you determine this info I can point you in the right direction for the size you need.

Okay, I dont believe I have that but I'll double check when I get home and get back to you.

I think that the 1125 is correct.
I tried to get a Gates but in Australia you cannot get 1125.
In any case in Australia the BMW original was only about $5-10 more so I suggest you may try your friendly BMW dealer, and then you do not need the length, only the part number.
