Hey guys,
So my Creamsicle has finally seen a road after about 1.5 year of jack stands time. (IMG:style_emoticons/default/cheer.gif) Now the speedo didn't work so I changed the cable. I see other cars passing by like a rocket while going at 65pmh so the speedo needle is way off??? I will check this with a GPS today. Anyways, the odometer is not working at all. This is a bigger problem. (IMG:style_emoticons/default/sad.gif) Has anyone encountered the same and succeeded to repair??? The speedo works(barely) but odo does not. Let me know. Thanks, kkid (IMG:style_emoticons/default/smile.gif) |

I have never seen a worm gear on any 914 speedometer wear out. Chances are the pot metal gear that couples the trip odometer wheels from the main odometer wheels is slipping on the main drive axle. This is definitely a DIY repair job.
The better question is the state of calibration of the speedometer. Is it off compared to your GPS? If so, you will be forced to mail your speedo to the professionals. They have a machine that will degauss the spinning magnet and then re magnetize it so that it reads the correct speed. This can't be done on the kitchen table. |
