continuing speedometer saga

Postby diversity48 » Tue Feb 14, 2012 2:58 pm



i'm getting a bit frustrated with the speedometer on my '82. first, the old cable started with the screeching noises. after lubing it several times, it eventually just broke (inside). par for the course, because i'm sure it was pretty old. i replaced it with an aftermarket cable that broke almost immediately. replaced that with an oem cable and that seemed to fix the problem, for about a week. then the speedo quit working completely. disconnected the cable at the top, ran it down the road, and the cable was spinning like crazy...so that was still good. i got a replacement gauge cluster from ebay, replaced that and thought i had solved the problem. seemed to work great for about another week, and then the speedo quit again.cable appears to be ok...any suggestions from anyone who's had a similar problem?

No,but if the cable is turning and the spedo isn't ,there are a few possibilities.
The other spedo also failed

The cable is not quite long enough to stay coupled at both ends In the spedo and the wheel gearbox.

You could disconnect from the wheel and chuck up a battery drill to spin the cable.Be sure it's rotating the right direction and the cable is the same distance inside the casing when you test.Spin the drill and watch the spedo.

I did see a tach cable like that.the cable spins but was just a bit shy of coupling to the tach mechanism.

I ended up heating the crimped coupling and pushing it further down the cable to expose more of the cable.

You can also verify the spedo by the same drill method.Use a piece of the broken cable to spin the coupler.

Also look at the couplers themselves.They should be square in the center.They may be rounded out and not gripping the cable well.

I think after replacing a couple of cables and buying a used cluster off eBay and still having issues I would come to the conclusion that the one you got off ebay was just as bad as your original. If you still have your old one, pull it apart and see if you can find what's broken and then I'd check the other one and see if it had the same issue. Maybe between the two, you can get one good one to work properly without the noise and constant failures.

SUCCESS! at least for now. turns out the oem cable i had purchased also failed. it broke at the base (just behind the speedo gear drive on the front wheel). i bought a motion pro speedo cable. this time, before installing it, i made sure it was COMPLETELY lubricated. maybe i hadn't gotten enough lube on the other ones, although they appeared to be well lubed. after the lube was running out the opposite end, i let it set (horizontally) overnight. after routing it, i connected the base (into the front wheel gear) first and then connected the top end into the back of the speedo. now it seems to be working like a champ! 3 commutes to work (18 miles each way) and absolutely no needle vibration or noise from the speedo. i'm keeping my fingers crossed that it keeps on working. i kinda doubt that all of my "pre-installation procedures" had anything to do with it, but i really don't care. it works, at least for now. all i can figure out is that maybe the other ones didn't get enough lubricant before installation?

If the speedometer drive isn't in the correct position (its lug up against the lug machined into the fork leg), it will cause too sharp a radius bend in the speedo cable right at the bottom, and the cable will fail in very short order. Ask me how I know. :) That's a possibility, anyway.
