Like many of you I've read this thread on fixing a stuck OD. Well today was my turn to clean up a frozen OD as mine stuck yesterday. What I will document here are some of the observations I made during the process.
When I went to disconnect the speedometer cable I didn't find any clip as shown in this thread. I did see a window on the cable housing and pushed in with a screw driver and the cable released.
I've heard/read that the speedometer needle will pull off. After a few tries with what I consider moderate hand pressure I gave up on it, not wanting to damage it. I figured out that to remove the clip on the OD shaft I needed to remove the two screws that hold the speedo face to gain more clearance.
Be careful when removing the OD wheels as one of the washers may stick to the housing.
My drive gear was different than the '84 that was used in the previously mention thread. Mine happens to be a '73 vintage.
As you can see in the following photo my gears were totally frozen/gummed to the shaft and would not budge. Also, the small gear has taller teeth every other tooth. These play a part in lining up the number. You just need to rotate the gear to get things to seat properly. You understand better when you actually start the assembly.
There is also a washer after the last number wheel.
I cleaned my parts with a combination of electrical contact cleaner and Dawn dish soap.
