Deflection Pulley

Post by marti » Fri Jan 19, 2018 1:09 pm

Be aware if your serpentine belt all of a sudden falls off!!, after a couple of hours of taking things apart and trying to fit a new belt I couldn't work it out why I had so much belt slack ???.....then I realised I was missing a pulley....sure enough #4 wasn't anywhere to be seen...snapped off...entire bolt sheared back to the alternator housing.....maybe a weak point waiting to happen worth getting a new bolt and doing just in case.....vehicle has just turned 100.000miles

Sorry after checking your post/ real oem diagram looks like it's the other belt, as it says the tensioner for the power steering pump.

Well yes Horizon, that must be the one as you do lose power steering all you dont lose is air-con, my garage is awaiting a new bolt from BMW which holds the pulley on and is special steel 150mm in length, none in stock and coming from Germany which is a good sign as they would have a few in stock if it was common....although mine is not on the recall list.....
