The drive belt failed on my 1999 Boxster and destroyed the idler pulley that mounts on the alternator mount bolt (or the pulley failed and took out the belt). In the manual section 13 78 19 on replacing the drive belt the pulley is referred to as a deflection roller (part number 3 on page 13-3). Does anyone have the part number for this pulley? The part number on the two remaining idler pulleys is 996 102 120 52 but the one that failed is too far gone to get a number off of.

TIA

Mike

I think it is 996 102 118 52 - called deflection roller. It is hard to tell because the parts diagram just shows pulleys and not their orientation on the engine. Send me an email and I will send you the page.
