Success
Hi everyone
I am happy to say I have got to the bottom of the Alternator drive belt problem .The belt I was trying to fit was a 4pk 592 elast belt supposedly the correct one for my 2003 1150 gs ( with a freewheel mechanism on the alternator pulley) I checked the No. both with the BMW parts supplier and a BMW dealer useing both reg No. and Vin No..After struggling for a few days ie keep going back to it I gave up and fitted the older Poly V belt as for the older system 4pk 611 This fitted straight on no trouble at all ( I still suspect that the origional 4pk592 was wrongly sizes so when I have chance I will take it to the BMW dealer and compare it ). But several people on various forums pointed out, why struggle as the correct "elast " belt is a pig to fit, just fit the old poly v belt adjust it the old way ie torque to 8NM and readjust next 6000 mile service and I will change it at 24000 mile instead of the new spec 36000 mile .
So in conclusion while I do like to service everything exactly as it is supposed to be I am afraid for my sanity sake I reverted to the old method .
Just for information sake any one purchasing the 4pk 611 poly vbelt it is readilly available at auto stores as it is the standard belt fitted to Hyundai accent / getz cars .
Regards Mike
