    I am currently carrying out a full rebuild on my 200tdi, I took the vacuum pump out without marking it. Now after reading manual, this has to be marked prior to removal, so the cam and skew gear realign when fitting. The cam turns 350 degreas then catches on the bottom of the vaccum pump and jams. Any ideas how to realign the corresponding teeth?

    Why is the cam catching on the bottom of the vacuum pump and locking the cam so that it will not turn?

    Cheers

    Yes it's catching on the bottom of the skew gear housing, where the bearings are

    I have tried two different skew gears in, both jam, I have also look at the housing to see if there is a shape for the cam to pass

    When I fit the skew gear into the block, the cam turns so far round and then locks and will not turn any further, when I take the skew gear out, the cam freely turns through 360deg. I cannot work out what I am doing wrong.
    Cheers

    Yes the skew gear spins freely same when he pump is fitted. There is slight movement in the cam, front to back, although the cam still catches.

    cam and skew gear timing as such is only due to lr thinking teeth would have run in together but experience shows its no concern
