Bouncy Speedo Cable

[Guest ScottG]

With Mrs G suffering a hangover this morning, it seemed like a good opportunity to put some miles on the hood.

 

However a few miles in (and in search of fuel again) the speedo began behaving in a strange manner.

 

Upto about 40 mph it is very "bouncy" for a better word, it is not smooth and consistent like previous. Above 40 it seems to be ok.

 

It does this on the way up and down.

 

Any ideas?

 

Going to check all the cable connections now but if anyone has experienced this before it would be great.

 

cheers

I have the same type problem on my 2B, I think it's the speedo inner cable draging inside the outer, i've got a new short cable (with a terratrip probe on the end) to fit so the cable won't have to be bent

A quick inspection reveals that I have melted the cable against the manifold!

 

So next question-

 

Where to get a new (longer) speedo cable from,

 

And how easy is it to replace the gearbox end- space looks at a premium?

It can be caused by a bend being too tight. Changing the cable can be a nightmare. I would tape it up and run some oil down the inner cable and straighten any bends as much as possible

Had a look last night. Bends dont look too severe.

 

I think I will try the oil trick first (best do my throttle cable at the same time) and see how that works out.

If you do lubricate the inner cable DO NOT put any thing on the top 6" of cable as it WILL make its way into the speedo head and make a right mess of it.

When I was an apprentice with Ford it was regular practice to have to lube inner cables with a small amount of grease but the above rule was always enforced on all of us "younguns"

[Guest ScottG]

The above is going to be difficult from the speedo end.

 

If I have to remove it from the box end I am aswell changing the cable assembly.

[Guest Ian & Carole]

I might be wrong but IIRC the inner won't come out from the gearbox end.

 

'tis a long time since I did one though.

[Guest ScottG]

The oiling seems to have made a massive difference. Still a tiny bit bouncy at low speeds <20 but ten times better than before.
