Crofter Posted July 14, 2013 Share Posted July 14, 2013 How are the pressures on 200 TDI injectors adjusted? I am planning to fit new nozzles to mine and I am wondering how to set them once fitted, I have access to a injector pressure tester so I can set the pop pressure if this is easily done, I don't want to buy new nozzles and then find I need shims or something like that.

Giles Posted July 15, 2013 Share Posted July 15, 2013 I don't know diddly about injectors, but I THINK I remember that these have a 2-stage opening, meaning that you can't set em up using a simple pump-style tester. Surely somebody knows... Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted July 15, 2013 Share Posted July 15, 2013 They are shimmed as far as I can tell, there is a rebuild thread on http://www.landyzone.co.uk/lz/f7/howto-200tdi-injector-refurb-110575.html and although he doesn't mention the shims (he used the originals) you can see them in the pictures. EDIT: They are a two stage injector Quote Link to comment Share on other sites More sharing options...
Crofter Posted July 16, 2013 Author Share Posted July 16, 2013 Thanks for the replies, I would have thought if there were new nozzles and needles fitted the pressures would need resetting using a injector tester, I have access to one, but if one has to pi55 about with shims this would be difficult, having the right shims etc. I did read the landyzone article and he made no mention of testing the after fitting the new nozzles, incorrectly set they may be worse than badly worn injectors and that would be a waste of money and potentially engine damaging.

In the last paragraph of post 9 he said he would take them out for testing again, although he never says whether he actually did it. Quote Link to comment Share on other sites More sharing options...
