UdderlyOffroad Posted July 30, 2010 Share Posted July 30, 2010 Hi All, Currently trying to change the cambelt on my 200 Tdi. Have got as far as removing all the bolts holding the cover on, but can't seem to get the cover off! The culprit appears to be the stud fitted on the top of the water pump, it looks like it has seized itself solid to the cover. I can feel 'movement' all round the cover, so it would appear to free everywhere else. Am I correct in thinking that under normal circumstances, one should be able to leave the stud in place and just slide the cover off over it (and the orientation dowel)? Unusually for me, I have resisted the temptation to clout seven bells of hell out of it using the LR Mark 1 adjusting thule - though I have gently tapped the remainder of the cover 'free' with a rubber mallet. Any ideas on how to remove this, without snapping the thing? Have already tried generous quantities of penetrating lube (the good stuff, not WD-40), the usual two-nut method (that's just stripped threads), am going to beg/steal/borrow a 'proper' stud extractor (the type that looks like a socket)? Don't have access to a 'smoke spanner' and nor would I want to use one in this instance All suggestions gratefully recieved! Piccy Quote Link to comment Share on other sites More sharing options...
RaDi90Hybrid Posted August 1, 2010 Share Posted August 1, 2010 Hi Can't help that much except that if you do crack the cover I do have one here which is on e-blag at the moment. Andy Quote Link to comment Share on other sites More sharing options...
errol209 Posted August 1, 2010 Share Posted August 1, 2010 If it is just hung on one dowel, a bit of scientific booty-shaking should eventually wiggle it free. A more damage method is to get the finest edged weapon in the armoury (I use an old 1/2" wide woodwork chisel) and introduce it along the gasket line using a light propellant (a bit of wood or the rubber mallet) alternately each side of the hung stud.

western Posted August 1, 2010 Share Posted August 1, 2010 if you can get a hacksaw between the pump body & timing case, you could cut the stud off & then extract it from water pump on the bench & replace the stud with part TD108201, M8 x 110mm, according to my parts info.

UdderlyOffroad Posted August 2, 2010 Author Share Posted August 2, 2010 Ok thanks guys, will wait till this stud-extractor-wotsit turns up from Eblag and if that doesn't work, will break out the hacksaw... Quote Link to comment Share on other sites More sharing options...
