MLP Posted March 12, 2011 Share Posted March 12, 2011 Just a quick question ....... The pulley has dropped off the end of the camshaft on my 200tdi Reading through the good old Haynes manual, it says that if I replace the camshaft, I also have to replace the skew drive gear - is this really true?

Les Henson Posted March 12, 2011 Share Posted March 12, 2011 Skew for the vacuum pump/oil pump? You might want to in order to make sure the gear mesh is perfect, but it's not essential. If the 200TDi cam seems expensive, then try the 2.5 N/A or T/D, or even the 2.25 series diesel/petrol - same thing Les. Quote Link to comment Share on other sites More sharing options...
MLP Posted March 13, 2011 Author Share Posted March 13, 2011 Yes, the oil pump/vacuum pump drive gear. I got a (very) good deal on a new cam, but the bst price i've seen for the skew gear is £130+ ...... pretty much doubling the cost of the othr parts ..... and I'm trying to be economical with the rebuild. If I had the luxury of time on my side (I need the thing for daily transport) I'd try and find a decent matched secondhand pair... Quote Link to comment Share on other sites More sharing options...
Les Henson Posted March 13, 2011 Share Posted March 13, 2011 Check the teeth of the skew gear - if they look ok, then re-use the old one. Les. Quote Link to comment Share on other sites More sharing options...
MLP Posted March 13, 2011 Author Share Posted March 13, 2011 Well, what a day Went to fit the (brand) new cam, just to find that the pulley bolt thread is different to the bolts I have ..... and in fact doesn't look good at all (looks like metric fine rather than course, and has been "flattened" somehow), so will have to go back tomorrow Going to see if any of the local scrappies have a motor in I can get the pulley, cam and skew gear from as a matched set...... Spent the day cleaning all the various gasket faces instead - that took a fair bit longer than expected, especially having to be carefull around the front, but once the bottom of the block was clean I covered the open front of the sump with some gaffa tape and wrapped the cam thrust washer in tape too, which made that end easier Quote Link to comment Share on other sites More sharing options...

MLP Posted March 14, 2011 Author Share Posted March 14, 2011 Well, no joy from any scrappies within sensible distance, so cam returned and new one expected tomorrow morning now ...... hopefully I can finally start to put this thing back together Quote Link to comment Share on other sites More sharing options...
