    3.0 D4 rear belt timing marks

    The version of the D4 WSM that I have shows a timing mark on the cam pulley in step 19 as being mid-way between 2 bolts on a spoke yet at installation step 4 with the pulley in the same position the timing mark has moved, now vertical and mid-way between the earlier spoke and the bolt to its right. It seems logical to have the timing mark vertical as per the assembly diagram and with the marks shown in different positions on the pulley, I suspect that step 19 is incorrect. Knowing which one is correct should assist with lining-up the crank-shaft for locking pin fitment.

    Can anyone advise which timing mark position is correct please?

    Yes JC. I'm expecting mostly by feel with judicious use of a mirror tool and anticipate some skin loss. A pump sprocket locking tool has been obtained.

    Graeme, I have "Discovery 4 2009-2011 R & W" published 11 May 2011. Let me know if you want me to check.
    Cheers,

    Yes please. Hopefully it will agree with one of LR's diagrams.

    Graeme, I think that I have a copy of the same WSM as Sean, published 11-May-2011.
    It appears to have identical steps 19 and 4 as per what you've described with the same discrepancy in timing marks.





    Regards,
    Scott

    Yes, those are the conflicting pictures.

    Its not a show-stopper in any way as the truth will be discovered when looking for the hole to lock the crankshaft.

    Picture 4 doesn't have the pump sprocket quite correctly aligned according to the picture at step 3 so picture 4 can only be used as an instruction to align the marks. As picture 3 shows an indent on the pump sprocket, I assume the cam sprocket will have a similar indent and that it will be vertical prior to cutting the existing belt.

    Is there a marked position on the belt cover that the timing marks on the pulleys can line up with?
