Speedometer stuck

Assume it's the old cable driven left front hub 356 repro Speedo?  If so take front hub cap off and check that cable sticks out the square hole in the wheel bearing cap.  Most use a C shaped clip to hold it on (or maybe cotter key).  Next I'd check back of speedo - is cable nut tighten on?  Remove it and look at cable end to see it is square at end.  Pull on end to see if it is broken somewhere in the sheathing.  My guess is it's the cable - pull it out - see if the inner drive cable out in one piece.  If all is good there - regrease it with Lubriplate or graphite.  Almost easier to replace cable with new one.  If that doesn't  work - then it's probably nylon drive gear in the Speedo.  It can be rebuilt - but costly.  Chinese repro are notorious for failing - Brazilian ones a little better.

If it does need a rebuild or replace, you have the option of a GPS Speedo.

Is it stuck at zero or some other speed?

It seems like if it was a faulty cable it would be at zero.

my husband ordered a new cable, got it installed, I took it for a spin, I was going about 40, it stayed at 0 zero....then it started moving a bit, got up to 45, then dropped back down to 30 where it was stuck before.  My husband even sprayed some graphite in it.  Nothing...

N. Hollywood rebuild, especially if its a Chinese repop

Some cables don't have a c-clip to hold the end in the driver's wheel hub. I've used both and on the 9ne without a clip, I had to zip-tie the cable to something (brake line?) to keep it inserted enough to reliably drive the speedo. Maybe?

Stuck at 30 makes me think old dried up grease in speedo and/or plastic worn gears.  NH costs seem to be near replacement costs but they use quality components.

Speedo cable end in cap w/o the small C clip you can dill the cable end out and put a piece of paper clip wire in the hole to secure it.    If the cable has excess grease  it could have worked it's way into the speedometer and coated the magnetic bell inside the speedometer that would also cause the problem you described.

My trip odo quit working so I sent it to N Hollywood.  $385 estimate to fix it.  No way I’m paying that.  I’ll go without a trip odo.

Tell us what kind of speedo it is or provide a picture of it.  I've taken several 914 VDO speedos apart and found the white grease turned to caulking.  You can clean up the gears and relube them.  I used white Lubriplate for fishing reels.  Oil or graphite would probably work too.  Some of the gears are nylon/plastic and others are pot metal.

Good article on taking them apart:

I’m not sure of the brand.  It’s 20 years old and sticker says “made in Brazil”.   I just finished putting it back in but I can pull it out again if there is a good fix
