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?

you dont need to mark vac pump it , its not timed and neither is skew gear on a 200 tdi , vac pump
 
vac pump should slot over pin in skew gear , skew gear which just pushes into place ,is cam catching skew gear housing
 
cant see where your going wrong whats actually catching where, vac pump doesnt timing though it needs to sit on the deepest slot
 
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.

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.
 
I will venture back to the garage again tomorrow night and have another look, it must pretty obvious what I am doing wrong just can't see it yet. Cheers Graeme
