ccconn Posted June 8, 2008 Share Posted June 8, 2008 Just been torquing up the cam pulley bolt on my VVC engine and before I got even close to the setting the bolt head has sheared off! Looking at the head of the bolt it looks like the bolt was fatigued Does anybody know of anyone nr to aylesbury who could come out and extract the bolt??

ECR Posted June 8, 2008 Share Posted June 8, 2008 Look on the bright side. Good job it sheared now and not whilst the engine was running ! Hope you get sorted soon .... Link to comment Share on other sites More sharing options...
k80rum Posted June 8, 2008 Share Posted June 8, 2008 If you can't get anybody out and can lock the cam pulley, there may be a somewhere open where you could get one of those easi-out extraction tools. I've not used one myself, so I don't know how 'easi' they are, but it might be an option if time's important. Good luck with it Darren E K80RUM Website and Emerald maps library Superlight R #54 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted June 8, 2008 Share Posted June 8, 2008 ouch !! 😳 As above - good job it didn't happen while engine running. Large enough thread diameter to be able to drill and tap a left hand thread in to use a stud extractor, hopefully. Was it the M8 or M10 size bolt - as they have different torque settings. Got me worried now - I removed a VVC cam pulley and re-torqued it only a couple of weeks ago when changing the rear timing belt. Good luck ! 7 related photos Link to comment Share on other sites More sharing options...
ccconn Posted June 8, 2008 Author Share Posted June 8, 2008 Thanks guys got it out with an extractor - phew As an aside looking at the bolt, the shoulder on the bolt before the thread had a crack in it which must have been why it sheared If you have one might be worth pulling the bolt out and just checking the it As you all said lucky the thing didnt shear whilst running!!

ccconn Posted June 9, 2008 Author Share Posted June 9, 2008 They were great thanks If the one you have at home is any more detatailed or useful then that would be fab too - working on the assumption that more info is better than less! Link to comment Share on other sites More sharing options...
