Re: ERT's E36 M3 96+ U/D Pulley

Yes, this is a very common problem with the underdrive pulley.  We had them 
pop off on our dyno, the track, and on spirited street driving!  95s also.
I believe it must be related to the loss of rubber isolation element in the 
crank pulley, since the A/C pulley is reused.  Crank vibrations must be 
enough to make the AC serpentine belt jump.  We recommend to all customers 
that use it to remove the AC belt before going to the track.

 Have any of you been encountering recurring probs. with the A/C belt?  Th=
 is is
 the 2d or 3d time my A/C's failed on me.  What I once thought was a singl=
 e
 isolated event has become a real pain.  It's painful to drive in 100+ deg=

 weather without A/C.
 
 Please let me know.  I've already e-mailed Larry Needs of ERT regarding t=

 problem.  I'll let you guys know what he says, if you too are encounterin=

 this problem.
 
 Thanks.
