Odometer repair

Share this page

~USUALLY~ we've been able to get enuff slack in the cables to undo 'em after the gauge is pulled out to expose the rear of its case.

As for the knurled nuts, I have what have been called "Lotus Fingers". Ten minute job...

All I need is a round-trip ticket. :jester:
 
71 MGB should have a 1280 at the bottom right side on the face of the speedo. If its a 1000 then your reading will be way off! The nut at the top center is a bear to get off. I remove the easier nut and bracket and then try to turn the speedo to make it easier to get at the other nasty nut. When installing, install the top bracket and nut with the speedo turned so that mess is at the bottom. then rotate the speedo and install the other nut. Tighten hard to get to nut if you can! When you are finished with that project you will understand why I like to play with earlier cars. 63-67 are much easier. Bob
 
Thanks guys...I'll give it a shot in the next couple of days. Doc I'd love to send you the RT ticket if only so I could meet you :smile:. But can't any of you just loan me a smart 2 year old??

I'm a smart two year old,---------------------------------------
with 59 years experience.

Wish I was closer, got time and small hands but 1 1/2 days away.

You can do it, just have patience.

Dave :savewave:
 
Dave...thanks for the offer AND the confidence in my ability !!
 
Well...as the "younger" generation says MY BAD !

I bought a used MGB Smiths speedo off of Ebay at a good price BUT it wasn't the correct one. It shows 1000 in the bottom right corner instead of 1280. What does this mean anyway? I guess everything would be way off like Bob says but how much (approximately) and in which direction? I guess I now have a speedo for sale :frown:

Gary -

That refers to the number of turns per mile (I think) coming off the cable.

I still have a couple of spares; if you'll give me the numbers on yours, I'll see if I have one that will work.

Mickey
 
Thanks Mickey...When Carla gets home from school with the car tonight I'll get the numbers off of it. It definitely shows 1280 in the lower right corner of the face.

Gary, The gears in the unit are made from a fiber material and when the shafts become dry they sometimes lock up and strip a couple teeth off. One gear runs the odometer and one runs the trip meter. It's not uncommon for both to go around the same time. $175.00 to rebuild it is not bad at all, just be glad you don't have a TF one to have restored! Close to $500.00.

This is out of a TF, but their operation and some parts are basically the same, as some MGB parts will fit. PJ

Should be quite a few around Gary. What year is your car? PJ
 
Paul...mine is a '71 MGB. Mickey has an old 1280 that he is sending me. We hope the gears in it are good and I can repair the odo and trip meter.

Gary
 
On its way...
 
Mickey...a BIG THANK YOU !! I have a new job that requires me to track mileage for pay purposes so a trip meter would be excellent !
 
My pleasure - hope it works, or you can use it to fix yours.

:cheers:
Mickey
 
It'll work somehow. Again, thanks. Hope we can do something for you or someone else somewhere along the line. Everyone just keep us advised !!

You already have, just by discussing your problem on the forum. Someone else out there will learn a bit and be helped from reading the post. Good luck with the fix Mickey provided. Hope it works out. PJ
