The speedo was off anyways so I tried again and managed te remove the needle with a fork. Was quite easy actually. I have taken apart the mechanism as far as I could without doing damage and found the culprit. The screw shaped gear that drives...

Aha, is there anyway to take the needle off so I can take apart the mechanism at back of the speedo?

Well, I just had a brainwave and decided to use my batterydrill to power the angle drive (as Jeremy Clarkson would say: “sometimes I am frightened by my own genius”). Not only have I established that the speedo works as it should, but also that...

I took the cable out and pulled it out of its sleeve. I can’t see any sign of damage whatsoever, so I am afraid that Norsemen was right and the speedo has had its day…

121K is not a lot for a mechanical speedo, I've had one that hit 300K miles and was still working fine. The first thing to fail is generally the mileage recorder.

Well, I rather first check the speedocable before emptying my pockets on a new unit🫠

121K. However, the engine is from a a Disco 1 so the mileage of the engine is unknown. Also the car is a bit of a mishmash created from parts of different classics. So the mileage itself doesn’t really tell me anything…. I mostly use it to keep...

That makes a lot of sense. Thanks for clearing up 👍🏻

The spindle generally has a little lateral movement for alignment purposes. In my experience, the jumping is caused by the cable inner binding in the outer, sometimes due to broken strands. The inner alternately catches and then frees so causing...

ahhh right so here is the explanation....

Haha, yeah I got that. But is it supposed to be so loose that you can fiddle it in almost any direction (not just clockwise or counterclockwise)?

I haven’t been able to source an speedocable yet. However, I have taken off the angle drive and sprayed some Teflonspray on it. Sadly this didn’t do the trick. I did notice that small pin that fits into the speedo was very loose. Is it supposed...

Aha, a friend of mine also warned me to use Teflonspray instead, so I’ll give that a try

Anything, but not WD40, it's a Water Dispersant not a lubricant, it leaves a gummy deposit.

Ah great, I will check the cable first and give the angle drive a bit of WD-40 for good measure👌🏻

Hi Everyone, I have an odd problem with my speedometer on my 1983 Range Rover Classic (powered by 200tdi from disco 1). The speedomoter was working fine when suddenly it started going beserk. The speedo is constantly jumping up and down whilst...
