網路上找到下面的說法,但看起來很精密複雜...
( 大意"好像是"把大表後殼拆掉後,用超小隻一字起子,把轉輪稍往右推,讓左邊產生一個小間隙。如此會讓每個數字輪可以被推動,再逐一推動每個數字輪到需要的數字)
Google for "Anthony Rhodes Speedometer" and download his 27 page PDF document on repairing Jaeger and Smiths speedometers. To get access to the inside of the speedometer you have to un-crimp the bends holding the chrome bezel to the speedometer case. Once you have pulled off the bezel and glass there are only two screws on the back of the case holding the speedometer movement in the housing. The Rhodes article explains how the odometers work and how to disassemble them. Basically what you will need to do with your Mk1 is to remove the movement from the case to gain access to the odometer wheels. With care you can use a tiny flat blade screwdriver to move the wheels slightly to the "right" leaving a gap to the wheel to the left. (This will make sense once you open the gauge up). With the screwdriver holding the wheels apart you should be able to turn the "left" wheel to what you want it to read. Do that from left to right changing one wheel at a time. Make sure the digits line up with each other and are visible through the odometer window in the gauge face. It is easy to get this wrong. If you are unable to make the small screwdriver method work for you, you will have to disassemble the spedometer and odometer more completely to move the wheels. Don't do this without marking the needle position relative to the drag cup or you will loose your speedometer's calibration (this will be clear once you read over the Rhodes article). |
