Q Catcher Posted March 2, 2012 Share Posted March 2, 2012 There's a second cambelt at the rear of a 1.8 K Series VVC engine. I'm about to attempt to renew it. Does anyone know if there's a special tool/technique for holding the two pulleys in place, so they remain in "register"? Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 2, 2012 Share Posted March 2, 2012 There is a post on here somewhere do asearch. You basically have to remove one of them ian Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 2, 2012 Share Posted March 2, 2012 It is very easy. I marked dots of white Tippex on old belt and both pulleys. Remove one pulley then transfer the Tippex dots to the new belt. Refit using loctite on bolt. I recall each shaft has a different size bolt, so get the right torque for the size you undo. edit: Looking at the manual, you need a cam pulley holding tool, which is basically like a big pair of scissors, with two adjustable pins on end, that you stick through the holes/spokes of the pulley you want to remove while undoing the bolt in the middle. I bought mine from a car shop or Halfords - not expensive. Details shown in the PDF pages I have for you .... I have a VVC manual on my PC, give me a few minutes ......

Q Catcher Posted March 3, 2012 Author Share Posted March 3, 2012 Sinking feeling time. Locked the engine at the flywheel. Did the tippex dots. Even counted the teeth on the belt. Made a pulley holding tool. Undid the bolt on the inlet side pulley and removed it. Mistake. Wrong pulley. The shaft behind the pulley immediately "pinged" round - but which way did it go? Judging by the keyway, it probably went about 90 degrees clockwise (looking forwards from the back of the engine). Rotating it anti-clockwise, I can take up some slack until I encounter resistance at about the 45 degrees point, after which, I think I can rotate it against a fairly heavy spring tension. So I presume it rotated 90 degrees clockwise, not 270 degrees anti-clockwise, but what if I'm wrong? Will the engine self-destruct? Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 3, 2012 Share Posted March 3, 2012 Oh dear Wait until I send you the PDF this afternoon. Got your mail ok and have replied. Don't crank engine !!!!!! Link to comment Share on other sites More sharing options...
Q Catcher Posted March 3, 2012 Author Share Posted March 3, 2012 Thank you, SM25T, and Jonathan, for your help. Appreciated. (And no, I won't crank the engine until I'm sure it's safe!) Link to comment Share on other sites More sharing options...
Q Catcher Posted March 3, 2012 Author Share Posted March 3, 2012 I've had a look online and found some illustrations of the VVC mechanism and how it works (see: http://www.mgcars.org.uk/news/news174.html). It looks to me like the mechanism has got 360 degree symmetry, i.e. if you accidentally rotate it 360 degrees, it makes no difference. If I'm right, then my earlier question of whether the shaft had rotated 90 degrees clockwise or 270 degrees anticlockwise should be irrelevant. So I've rotated it 90 degrees anticlockwise, picked up my tippex register marks and refitted the belt and pulley. I think the engine will be OK. If anyone knows differently, would they please shout now?! Link to comment Share on other sites More sharing options...
