Gromit Posted June 12, 2006 Share Posted June 12, 2006 I'm replacing the timing belt on my 200tdi, and a good job too. There's a fair amount of oil coming from the crank oil seal. I still have the old belt on and I've turned the crank until the woodruff key is at 12 oclock. The cam sprocket mark is 180 degrees out from where it should be, at about 2 oclock instead of 8. How did this get timed like this? I'll be taking the cam sprocket off to replace the oil seal. Can I refit it 180 degrees out, i.e in the correct position? How should I proceed? TIA!

GBMUD Posted June 12, 2006 Share Posted June 12, 2006 In the words of HHGG, DON'T PANIC. Turn the crank another 360 degrees. The cam and the fuel pump turn ONCE for every TWO turns of the crank - that is why the pulleys are different sizes. After you turn it again it will all allign. Trust me, there would be small bits of metal if the cam really was 180 deg out! Chris Quote Link to comment Share on other sites More sharing options...

Guest diesel_jim Posted June 13, 2006 Share Posted June 13, 2006 Just don't do what I did a few years back... changing the belt on my 200, somehow i got distracted/bored and ended up fitting the belt with the FIP pulley 180 degrees out..... the engine ran fine! had a slight knock to it, but power was all as it was before! until 6 months later when the crank split in 2 between 2 & 3 cylinder! obviously a lot of stress was being put on the crank!

Correct me if I am wrong, but that would mean that the diesel was being injected at the top of the exhaust stroke... surely the engine could not run under such conditions?

Tonk Posted June 13, 2006 Share Posted June 13, 2006 also pin the injector pump in situ whilst changing the belt, 9.5mm drill bit, insert through hole in pulley. Quote Link to comment Share on other sites More sharing options...

The engine would be very much down on power surely? Quote Link to comment Share on other sites More sharing options...

Take care when removing said drill bit though the rad is awfully close by Quote Link to comment Share on other sites More sharing options...

white90 Posted June 13, 2006 Share Posted June 13, 2006 personally cock up experience Tony? O yes 9.5mm drill bit through a 6month old rad! then a drive to Taunton to have it fixed stopping every 2 miles to top up header tank.. Quote Link to comment Share on other sites More sharing options...
