Hi Everyone
Happy New Year to you all. Just a question re LC/LJ speedo cables. My LC has a 308 and Trimatic with the shift on the drivers side. The speedo cable goes from the speedo, through the firewall and into a small aluminium looking mechanism. Another cable then goes from the other side of the mechanism into the tranny. I have snapped the cable (probably because I didnt route it properly under the dash) and I am not sure if its a standard 6cyl cable, a V8 one or a custom one. How many types are there? How do I know which one I have.
All help appreciated.
Cheers
Nando

I\The "aluminium mechanism" sounds to me like speedo converter.

 

The 2 cables will be custom. One from the auto to the converter & one from the converter to the speedo.

Thanks Dr Terry. I'll get under it tomorrow and pull the cable out and then I'll try and match it up.  The converter I assume is to converts from manual gearbox speed cable to auto? I am hoping the piece from the speed to converter is the standard 1600mm long  speedo cable.

No, the converter corrects the speedo reading, if/when a diff ratio or tyre size is changed.

 

See an instrument guy to get a new cable made, not expensive.

Ok got it, so the bit from the back of the speedo to converter won't be standard?

Any clues who I could go to in Melbourne? There's Howard Isntruments in Heidelberg but I'm no chance of getting anything out of them anytime soon.

Thanks Albert

I went to Rare Spares and put my speedo cable next to the off the shelf LC Torana (part no 2806786) and it lined up perfectly both in length, needles and hand screws.

I took the speed converter with me to make sure it screwed in and It did. Fitted it up and it all went in ok. The only thing is when I take off, it sits on zero and once you build up speed, it jumps up to the correct speed and the needle remains steady as a rock (the old used to bounce around a little. I have a digital GPS speedo which has both MPH and KMH and they match perfectly.

Any clues as to why it doesn't start reading until I get some speed up?

Cheers

Nando
