Speedometer
Speedometer
Back in August my speedometer quit working. I naturally thought it was the nylon driven gear. So I put one in. It quit again after only 14 miles. So I ordered the whole box on the wheel. Now nothing works. I put a drill on the cable & spun it. It works. So I thought maybe the dog that turns everything in the hub but it spins. So now what do I look for?

Re: Speedometer
If the brass bushing under the speedometer is stuck due to debrie or dirt, the cable can not spin freely, and it causes the cable to twist inside.
This may be causing the plastic gear damage.

Re: Speedometer
Did you actually pull the inner cable out and inspect it for rust traces on it? The outer sheath of the cable is made from regular steel that rusts. Rust is known as cancer in the northern states as it grows in size. That growth puts pressure on the inner cable which eventually binds and snaps the nylon gear in the drive box.....
Replace the speedo cable if the outer sheath is rusted..

Re: Speedometer
What about the nylon gear broke/wore out? If it's the teeth, Id suspect the problem cable/speedo side. But if it's the tabs on top, could something be wrong with the ring with the rubber tabs in the wheel that drives the nylon gear?
Re: Speedometer
Speedo cable ends are square, maybe the hole(s) they go into are rounded?
I'm hounded for posting helpful solutions? ARGO!!! (2012 film)

Re: Speedometer
Check the inside of the speedo while you're at it. A buildup of "gunk" in the speedo "collet", for want of a better term, caused mine to break above the square end at the drive gear where it is connected somehow, luckily without breaking the drive gear. It took some time to clean out the well in the speedo and get it turning freely, but it has been doing fine since then when the new cable went on in August '16, and no more needle bounce!
Autocorrect has become my worst enema!
