Hi there

Has anybody any basic maintenance advice for one of the smiths speedometers?

I have an 80 mph one on my b32, It works but sometimes the needle leaps around erratically showing all kinds of random speeds.
Is there a way to maintain them or fix this probem?

Thanks

max,
About par for the course for a Smiths. I think there was a thread on repairing these speedos some time back. I have not had any good luck sending them out to be fixed. Might just try it myself sometime. What could be worse it flutters all around anyway. there are some aftermarket speedos for about the same price as a repair...Taiwanese I think. Maybe someone will chime in.

Mr Mike

Maxwell; Is that a chronometric speedo you have. Most of the advice seems to be for magnetic types.

However if you look in members Projects under "1955 Triumph Thuderbird WVK 345" on page seven you will find a lot of good information on sorting out the chronometric.

Without frequent roadside repairs there is no fun in riding!

Usually it is either the cable or the drive and not the head although if it has not been to the shop since BSA installed it then it is way over due for a clean & lube.

Hi there thanks for the pointers, I cannot seem to get the search function to work so couldnt find the other threads.
This is the first time the bike has been ridden for about 15 years i think. Speedo worked fine for about 100 miles, then it started to go wrong.

I'll check those links

+1 an what the others said but if you do need a rebuild of your original intrument...

Joel Levine in Atlanta GA did a great job re-doing the Smiths for the Firebird.

Had the same prob with my speedo, took the cable out, sprayed a bit of WD40 up inside, unorthodox, but it worked and the needle is as steady as a rock.
