geojackson Posted January 21, 2009 Report Share Posted January 21, 2009 Can anyone let me know how many starts I need on the speedo drive gear, and how many teeth on the pinion to complete the installation. My rear axle ratio is 3.7 : 1 Help will be greatly appreciated. George Quote Link to post Share on other sites
Dave Herrod Posted January 23, 2009 Report Share Posted January 23, 2009 George, See the current forum topic in the sidescreen section. I did this conversion a few years ago and got the correct drive gear and pimion from overdrive repair services in Sheffield. From memory, I think you need a drive with eight starts and a 20 tooth pinion for the standard 3.7:1 axle, but ORS will confirm if this is correct. I think the standard saloon o/drive has five starts. Dave Quote Link to post Share on other sites
