My personal thanks to those who pitched in with information on the lambda "speedo" cable. That cable is now resting in a box of Volvo nostalgia.
Now comes another trick to master.
I thought I could install my 240's instrument cluster, no problem.
And for the most part, almost did.
Tach works, etc. but the same speedo unit won't give up without a struggle.
I see the fitting on the speedo's backside; it has what appears to be a non-threaded opening surrounded by a grey pot-metal-looking, fixed, stationary "cone" that appears to have a couple quite large threads.
I guess that device somehow connects to the speedo cable which can be twisted/pulled tight to the speedo.
But I don't see how.
My speedo cable ends in a chrome surround, which I can push into the non-threaded opening--but it gets no traction. Thus, the speedo gears do not turn.
So, there it is.
Is there some sort of gizmo that MUST be on the end of my speedo cable to twist it tight up to the speedo unit?
If so, that means my speedo cable is defective and must be replaced?
Thank you in advance for any information you may provide.
