    Just replaced my centre bearing and realised when putting it back together that it was incorrectly assembled before by someone else !
    The yoke was rotated 90 degrees so my marker is usless unless i want to put it together the wrong way again. I'm pretty much resigned to taking a 50/50 chance and hoping not to have to take the exhaust off agian.
    Is there any way of telling which of the two possibilities might have been the original ? I've looked for previous marks and paint etc but nothing obvious .


    cheers

    Not sure what you are describing.... are you saying the original fitment had uni out of phase/offset 90degrees? See FSM* - PD section page 7 for correct alignment.

    *Barry supplied you with a Zed-Stuff CD I think?

    Many thanks mate.

    Yep, i did get the disc from barry - a great resource - sure beats searching the web and downlaoding stuff all the time - AND there are some great recipes on there too ( well done ! )

    The original fit was correct but someone has reassembled incorrectly since then. So most recently it has been out of phase - i believe....

    You were very close: PD page 6 has the tailshaft assembly
    but it incorrectly shows the companion flange as circular and thus gives no clue to the correct orientation. Traces of black paint and the slightly rectangular shape of both flanges ( an illusion created by cut aways on the sides - the holes are in a square formation ) make the proper orientation clear.
    There are recesses at the base of the uni joint casting, and these have allowed a pattern of black paint on the companion flange which was 90 degrees out from it's most recent orientation.

    not sure if i'm making things any clearer ?

    i'm now not sure if the black paint is orginal as it seems to mask quite a few scratches which i doubt would have occured in the factory.

    Ah ha ...
    a closer look at the pic in tech section of the forum reveals my suspicions are right, and my unit was incorrectly assembled ( i was working form a poor quality printout ).

    So - i still have to decide which of the two possible 'correct' orientations is most lilkely to be the real ( and balanced ) one.

    any wisdom greatly appreciated.

    cheers
