Hi all..
as the title says the crankshaft pulley on my 2008 A4 B7 3.0 tdi (233) Engine code ASB has separated itself and snapped the belt at same time. The remainder of the crank pulley I managed to remove without taking anything off at the front,just the bottom engine tray had to come off. A new pulley and belt have now arrived but before I attempt at getting either the pulley or belt on there’s a fair amount of rubber from old belt on some of the other pulleys especially one in particular an idler pulley so I intend to heat up the rubber to remove first as is now rock hard.. questions I have for you all is..
should all the pulleys move freely as they are I.e no belt on them as the air con pulley is pretty solid and won’t spin by hand whereas all the others do?
I’d rather know for sure this is normal before I attempt at putting new belt on..
And am I right in assuming that the tensioner is at present de-tensioned with no belt on? And is it a case of prising it closed so to speak with something when putting new belt on? I’ll be trying to feed belt down through bonnet to route the belt. I’ve done a fair few things to this car myself like front mount inter cooler and turbo down pipe (awkward) but this seems pretty straight forward providing I have the space to work with.. just hoping someone out there knows the answer to the air con pulley before tomorrow as I’m refitting it all in morning fingers crossed.. thanks peeps!!
