Hi guys new to site I have 90 softail fxstc my speedo stop working
And the speedo gear walk back and the tab that sits in hub is out what causes this and what holds it on the axel from wallking off like that and is there any specail tools to change it

 

If its walked along the axle then the spacers are wrong.

 

Its never been apart there is no spacer there

 

Did the odometer stop working too? If so, I bet it did, then...
Take off your dash and carefully remove the rubber boot that weatherproofs the electrics then unscrew the speedo drive. I would jack the front wheel off the ground and spin it. This is easier if another person can help to spin and you can see the male end of the speedo cable. You want to see if it is moving, spinning to ensure that it is working. If it ain't working then it is a good bet the speedo is cool but the drive or the cable is bad.
The drive is not serviceable per se because the worm gear is a bytch to remove the tiny flathead set screw. The drive from DS is $33. The cable varies by color and by manufacturer, length (stock vs ape height) etc...
I have not test for the drive or the cable. If you have owned the bike for awhile you can swap both of these out for less than $75.
The drive is the right side spacer and on my two bikes that have new drives and cables neither of them had a spacer in the brake/speedo side. The visual test would be if the drive notch is in the hub.rotor assembly.
On my 1995 flstc my drive was seized but I guessed wrong an bought a new cable then I discovered the crap drive because I installed the cable.
On my 1998 fltr I, having previous experience, decided that the drive MUST be bad and replaced it only to spin and have 0 miles to be reading after furiously spinning the wheel for miles.
The good part that this stocker cable was $18 from my favorite indy shop.

Good luck!

The middle of the speedo drive flange may be rotten. The drive is held in place by the spacers and shouldn't walk.

It is possible that you are seeing it wrong and the drive has seized up and pulled the tab from the slot.

 

pix? add some for a bit more help.

 

Found problem it is a newer hub has anyone put a trans speed gear on this to remove the speed gear onthe rim

 

I don't know if that will work as the older transmissions weren't setup for this but somebody may have another answer more to your liking. I just don't know if I've ever seen it. I am very interested because this winter's mod(s) will be a big one for me and I may need another way to pick-up the speedo.

I will say that on the JJ I have seen people go to the rear wheel for their speedo drives because they go over to aftermarket springer front ends.

Please update WHATEVER you do 'cuz I'm interested.

thanks,

tom

 

I've heard it can be done , but you have to change trans housing & speedo head to electric , never seen it just read it some where

 

That isn't practical! What is the wheel it currently has? There may be a way around this.
