Midyear Clock Repair
From Mike Cobine, corvettedoc@geocities.com
Clock repair in Midyears is really simple. If you just want it to run and not
want a face restoration, then pull the clock out and do it yourself. You will
save more than enough for gas money.
-
Pull the clock out of the dash. You should be able to reach the clips holding
it by removing the side panels by the radio.
-
Remove the back cover. Some twist tabs, I think.
-
Take a points file (ancient technology) and file the contact points smooth.
Usually they are pitted badly and sometimes stuck.
-
Go to your friendly electronics supply store and get a can of TV tuner cleaner.
Spray the shafts that pass through brackets, gears, etc. The idea is to clean,
not drown. This will also lubricate it some. Take care NOT to get it on the
face of the clock.
-
Test it before buttoning it back up. You need a ground wire and 12 volts. It
should take off on its own, but if not, pull the points up slightly (wind it)
so they will wind down to jump open again. If you have to move the flywheel,
you may need to respray it.
-
After you comfirmed it will run on its own for 15 minutes or so, put the rear
cover back on and stick it in the dash.
