Greetz all,

How does this thing actually work ?



Are you supposed to twist it to reset the trip mileage ???

 

Screw it itno the back of the speeodo case,,,make sure the square internal drive cable that turns the trip odometer. Pull out the cable and apply light grease then reinsert the cable and check again that it rotates the trip odometer.
Put the **** on the other end of the cable where it mounts under the dash,
PUSH in on the **** which causes the cable inner core to engage the trip odometer.
Rotate the **** while it is pushed in to change the Trio odometer back to Zero miles.

 

from what you have pictured, you are missing the setting **** which goes on the end of the cable afixed to the lower edge of the driver's side dash panel near the vacuum override switch assembly. having the **** (which you can buy a re-pop of if necessary) makes working the system much easier. my cable was also missing the ****, but was seized badly so i just replaced it. it also looks like you are missing the locking nut that you secure the **** end of the cable to the dash panel bottom

 

How does it actually work? Well.....

Inside the trip odometer, it's like this when you're not touching the reset. The shaft is slid to the right side by the spring inside and the worm gear there is from the speedometer cable and drives the odometer (removed in this picture) and trip meter down at the bottom



Here's the trip odometer and the gear at the end so looking up from the bottom, way in the background you can just see the regular odometer


On the bottom shown here, the pointed end bit on top of a gear with the spring under it is what the reset cable is attached to


When you push the cable in it moves that point against the taper on the side of the trip odometer shaft and forces it to the left, this disengages the gear to speedometer gears so it's not connected anymore and meshes the gear that gear to the gear connected to the reset cable instead (barely)


Then when you turn the **** (while holding it pressed in) it turns that end number and when it lines the 0 with the 0 on the next ring it picks that one up and they rotate until the catch the next number ring etc etc etc until you get them all to zero and stop turning.

Usually what happens is they get bunged up and don't slide all the way back to the right to engage the regular speedometer gears again so they just sit. Sometimes it's the cable sticking and if you pull it down instead of pushing it lets the shaft slide back to the right.. sometimes

Amazing pictures and information Mooser!

 

Agreed! Talk about a great answer to a question!

 

Agreed - this was quite fascinating.

I was looking at the squared of end of the cable and thinking... well, this needs to be twisted... and... that can't be, that's nuts !

Thanks for clearing this up for me

Now to see if mine still works.
