Odometer repair
Posted: Tue Aug 14, 2007 1:45 pm
Ok ,here it is again,as I posted it on the OLD real 4x4 board.
Patiently/carefully peel back the bezel ring with a screwdriver or
side cutters,and remove the ring.
The next part is tedious,warm the speedo housing around the lens with
a hair drier to loosen the tar like sealer,use 2 small flat blade
screwdrivers on to pry the lens on opposite sides ,slowly walking the
lens off.
next remove the trip meter cable and the rest of the fastening
screws/nuts.
Now the guts are in your hand,look at the small worm gear,it is most
likely backed out,don't push it in yet!
Pull the worm gear out the rest of the way , and swab out the pin
bore.
Put a SMALL DAB of super glue on the tip of the worm gear shaft and
push it back in,YOU ARE NOT DONE YET!
This may sound wierd ,but get a small metal picture hook(the kind
that is folded and uses a small nail),unfold the hook to make a brace
to hold the pin in .There is a screw on the speedo body by the worm
gear ,bend and cut the hook to fit to this screw and over the end of
the worm gear shaft,apply a small amount of anti-sieze between the
worm shaft and the new limit/retainer you just made.
Test prior to re-assembly by rotating speedo input.
I wish I had a working camera when I did mine, a picture is worth a
thousand words.
I have over 12000 Miles since I repaired mine,and it still works fine.
I was shocked that a new(used) speedo head was over $400 , that is
why I repaired mine.
I am used to these kinds of repairs as I have restored many cars and
car parts dating back to models from 1916 and up. You can't get a new
part for those golden oldies ,so you find creative ways to repair,or
extend the life of the parts you have.
The alternative is to take it to a speedo shop, or try to negotiate a
good price for a replacement,or go electronic.$$$$$$
Hope that helps, Jim LaGuardia 74 710M.......been there , done that!
