I'm looking to take my speedo apart for some cleanup and repairs. What's the secret for getting the mechanism out of the housing?? The odometer reset pin is not allowing me to withdraw the guts. I have the bottom part of the reset off. Do I have to take the dial face off???

Edit: OK, I bit the bullet and removed the needle and gauge face and it slipped out of the housing without a problem.

The odometer part of my original speedo doesn't work, plus the rod for the trip reset was broken. So I bought another speedo off ebay hoping I could swap over some parts. Looking at both of them now that they are apart, I will have no trouble making one good one from the two.
 
Whoa, Thanks for the link. There's some great stuff there. /ubbthreads/images/graemlins/cheers.gif
 
One of the most common things I've seen in the speedos is that the shafts of odo gears stick in the brackets. Then the fist time they get used in 30+ years the teeth on the pressed fiber gears dissapear into a pile of dust in the bottom of the speedo case.
It's fiddely to get everything freed up but it saves a lot of trouble to do it during the resto, before you try to drive the car.
 
Those odo gears are what I'm replacing on the original. The odo never worked from the day I got the car. Fortunatly, the gears in the speedo I bought from ebay are OK. I took a gamble, but it payed off. /ubbthreads/images/graemlins/cheers.gif
