    Aux belt and Tensioner help

    Hello,

    If any one could shed any light on this i would appricate it,

    This is on the M54 Engine

    I have ordered the belt and tensioner,

    On real OEM: RealOEM.com * BMW E85 Z4 3.0i Belt Drive Water Pump/Alternator

    I need part 2 which has been discontinued, but there is a new one part number: 11287838797

    What i was expectig was something that slightly resembles 2 in the diagram as that is what it looks like i have on the engine
    So this is what i have recived:( i also have the pulley in anouther bag)


    to me it dosent look like it is going to fit, as its no the same shape etc.

    Any help would be appricated

    I'm not 100% Sam but I think @dailydoggy had a similar issue when he came to replace his unit, iirc that is the new hydraulic unit whereas you will have the mechanical version?

    Hopefully the @ function will work and the dogmeister will confirm all

    edit - theres the mechanical version available @bmwpartonline add it to the shopping cart and the part image appears in the cart

    I should of read about this first

    Luckily I've found a diy online that shows how to do the swap. Mechanical to hydraulic it doesn't look that bad I'm gonna give it a go as I have all the bits

    Thanks guys

    What I can't work out is how do you release the tension on it? The mechanical is just the bolt in the middle but the hydraulic?

    ahhh yes, i have anouther pic if anyone else is ever in the same situation:

    you need to lossen this bolt ... or not do it up tight it the first place then tighten it after:


    Its a bit of pain to get to, i couldnt get a socket on it as the pulley is in the way
