Guest 72 blue Posted March 20, 2006 Report Share Posted March 20, 2006 Afer taking the car for a good run saturday my speedo seems to have lost calibration at least 15 mph over 50 mph is the a way of correcting this or does the speedo need rework or calibration as I am bound to get caught in a camera yet again Quote Link to post Share on other sites
jerrytr5 Posted March 21, 2006 Report Share Posted March 21, 2006 Check/replace the speedo flexible drive and angle drive first, but it sounds like your speedo needs a rebuild. Speedycables offer a rebuild and calibration service - check their website on the measurements they need for calibration. Quote Link to post Share on other sites
Dave Herrod Posted March 22, 2006 Report Share Posted March 22, 2006 I do not think this is a calibration problem unless something has changed in terms of final drive ratio or tyre size. It is more likely that the bearings of the drag cup inside the speedo are binding. You can take it apart and re-grease it (a search through past posts will give details of a website that tells you how) or you could send it off for a service. JDO instruments give a very quick, fixed price service. Dave Quote Link to post Share on other sites
