Odometer reset wheel

There was a very cool 'step by step' thread, with pictures that I viewed a few days ago about taking apart the atari and fixing wiring and bulbs. I can't find it now. Any help? - The reason I was looking is because it showed the odometer reset wheel ( mine broke off) and I was trying to see if the wheel can be unscrewed( left handed thread) without taking apart the whole atari. So - if you know which thread it was - can you copy and paste it for for me, or even better, if you know if the wheel assembly can be removed without taking apart the whole panel - please advise. It will save me a lot of time and trouble - thanks, Rick

 

Rick,
I did a forum search for atari and I think I found the post you are lookin for. Unfortunately I am not intelligent enough to copy and paste it. It was a post about changing to red LED's in the atari. Maybe this will help a little.

 

You should be able to unscrew the tripmeter reset knob without disassembling anything else. The speedo itself is mechanical and not very different fom the others; however double-check inside the end of the knob to be sure it isn't retained by a tiny screw instead.

 

From what I remember, there was a little 'left to tighten' screw in the exploded diagram and that's what I wanted to find out about. If it's accessable from the wheel part then that's good news. I've since 'fixed' mine by hammered the end of a nail flat, heating it up and forcing it into what was left of the shaft. Once it cooled it was secure enough to turn the trip odometer without twisting. I then found a suitable wheel replacement ( the cut off end of a bic pen top) and it works fine. I just happened to have phoned a used bike parts place about 10 minutes away - just for fun - to see if they had any old 82 yamahas in their yard and ....... they guy said they brought in a 750 seca a couple of weeks ago. I'm going to take a look tomorrow and see if there are any usable parts so I just wanted to be know how easy it would be to get the trip wheel. Sure be nice to find some spare plastics, mirrors, and other stuff. Heck, I might try and buy the whole bike!

 

Boy, do I feel stupid. I visited my local bike wreckers and they had half a dozen 81/82 yamaha 650s in their yard. I showed the guy what I wanted and he just went to one of them, turned the knob in the opposite direction, and the whole knob assembly came out! No disassembly required, no little left handed screw either. Cost me $10. I'm learning a little everyday!
