79 GL1000 Speedometer trouble

Postby khartsh » Wed Sep 01, 2010 9:15 am



OK, This has became a problem that has been ongoing and now driving me CRAZY. I recently completed restoring my 79 GL1000 and Everything was just Awesome. Parked it one day and the next day the speedometer quit working. hooked a drill up to the cable at the wheel and had no response so I replaced the cable. All good then. Next day, didn't work so I replaced the speedometer gear box on the wheel and it worked fine for about 1 mile. Now I check the speedometer gear drive in the hub and it fits tight and catches the gear box gear and i can turn by hand from that point but once back together it still only bounces around at 8 mph when running down the highway. I have made sure that all connections where in place and secured properly I have manually checked the speedometer itself and it works fine. Is there something i am missing that could cause all these speedometer headaches? Thanks.

Well, you've replaced the gearbox and the cable - assuming that if you lift the front wheel and spin it, you can see the cable spinning correctly at the top end, the only thing left is the speedometer itself.

I checked the speedometer first and third. Shows no signs of trouble. Is it possible the gear box Drive Plate can wear down enough that under normal running speed it could have play and slip inside the gearbox? Kind of pointing to that end. By hand it feels like it catches but just doesn't hold. Thanks for your help.

I had this same problem on my '76 GL1000 LTD, and found that by spraying WD-40 up into the connector on the speedometer body, that it lubes up the internals and resolves the problem. I had to cut a speedometer apart to find this problem, but it was worth it. :idea:
