The definitive guide to the repair and calibration of Smiths magnetic SSM speedometers and RSM tachometers
 
Fix it yourself and never have to pay or wait for repairs again
 
Instruments can be calibrated on bike or on an easy to build rig
 
Full instructions given every step of the way. No specialist tools required, just a cycle computer
 
Also covers fault diagnosis, cable and drive gearbox maintenance and repair
 
Unless a speedometer repair specialist asks you for the circumference of the rear tyre and ratio of the drive gearbox you are using, you are missing out on potentially greater accuracy that you can get by calibrating the speedometer yourself. Standard calibration gives an error of up to 5% with 1600 revs per mile instruments and sometimes more than this with 1000 revs per mile. This book shows you how to tailor the calibration for the machine the speedometer is used on and in most cases accuracy to within 2% can be achieved
 
Many instruments will only need cleaning but this book also shows how to repair a shattered magnet, replace the upper bearing and fix an aluminium disc turning on its spindle. All repairs can be made at zero cost with the usual hand tools. If you can repair rather than replace with a part taken from a donor instrument then you will help all of us by preserving the stock of these instruments

Colour covers, B&W interior, 6.6x10.2 inches. 84 pages, 16,500 words. 57 illustrations. First published July 2009

It helps you achieve something thought for many years to be only capable by highly skilled specialists. So as well as saving several times the cost of the book when you make the first repair, you get a buzz that no amount of money can buy by having done it yourself.
