Bigrich22 Posted September 2, 2016 Share Posted September 2, 2016 Hi all need a little advice 55 plate Ford Focus @Tdci-Peter @Dee_82 gear crank shaft pulley which has a magnet strip running along the outside of it can any one tell me if the magnet is supposed to be continuous because mine has about an inch missing I've taken a photo so you can see which pulls I'm talking about but the photo doesn't show the missing magnet cheers rich Quote Link to comment Share on other sites More sharing options...

These rings must have a gap or other feature, to act as a datum point for each revolution, then close spaced teeth or magnets the rest of the way round to allow fine timing resolution.
