Mpgp1999 Posted May 4, 2022 Share Posted May 4, 2022 Hello I am trying to service and reset my speedometer. It began working erratically. I removed it and cleaned it, and applied some oil to the shaft. I am not sure how to roll the odometer to zero. Link to comment Share on other sites More sharing options...

Mpgp1999 Posted May 5, 2022 Author Share Posted May 5, 2022 Considering this is a junked speedometer. If the mileage was true it would be different. My speedometer has not been connected for as long as I’ve had it. Link to comment Share on other sites More sharing options...
JFranklin Posted May 5, 2022 Share Posted May 5, 2022 It sounded as it was an in use meter. I wasn't genuinely concerned much. Link to comment Share on other sites More sharing options...
Mpgp1999 Posted May 5, 2022 Author Share Posted May 5, 2022 The problem I am having is the magnet is in contact with the rotating speed display. Sand it? Graphite as a lubricant? Link to comment Share on other sites More sharing options...

JFranklin Posted May 5, 2022 Share Posted May 5, 2022 I had that trouble with one and the piece with the numbers had moved/warped out of being concentric. I gently manipulated it back round. I thought you were having trouble with rolling back the miles. I think if things are free you go forward to 00000. But you better know for sure. Does the trip counter work freely?

Mpgp1999 Posted May 5, 2022 Author Share Posted May 5, 2022 (edited) I was having trouble with the miles. I figured it out. I punched the odometer shaft out and turned the numbers by hand. It was at 76k so it did not take more than 15 or 20 minutes to do. All Solved. NEW ISSUE: The speedometer gets pegged at the max speed with just turning it by hand Edited May 5, 2022 by Mpgp1999 (see edit history) Link to comment Share on other sites More sharing options...
RichBad Posted May 5, 2022 Share Posted May 5, 2022 I think the only way to get it back to zero is remove the drum and disassemble then re assemble at 0/0/0/0/0. Just pay attention when you pull apart as there’s a few parts in the drum and the order of assembly is important. or you put it in a drill and keep it running till it gets back to 0.

Mpgp1999 Posted May 5, 2022 Author Share Posted May 5, 2022 When turning the speedometer shaft by hand I can hear it grabbing the dial and it becomes stuck to the magnet, by friction and pressure. Link to comment Share on other sites More sharing options...
Mpgp1999 Posted May 6, 2022 Author Share Posted May 6, 2022 It appears I have a new issue. The speedometer cable is not turning. There is a problem with the transmission speedometer linkage. Link to comment Share on other sites More sharing options...

cutdown Posted May 7, 2022 Share Posted May 7, 2022 (edited) My speedo has seized [ the drive wont turn ], and I cant get it apart. Can anyone throw some light on how it is supposed to come apart. I have removed the 4 screws from the circumference and there were 3 screws in the back of the head which I have removed. Just need to know for sure which bits slide apart before I start putting pressure on it. I sprayed some loctite Freeze and Release into the drive so will wait to see what happens. Thought I might as well spray it on the body and sure enough, it came apart easily without forcing. The speedo drum moves freely so its probably only the seized drive. After leaving it for a while, I managed to get it turning using a screw driver. Not too hard to turn but too hard to spin with my fingers using a cable end. Seems to have a tight spot, but still not free all the way around. Edited May 7, 2022 by cutdown more info (see edit history) 1 Link to comment Share on other sites More sharing options...
