54 Split screen - juke box dash. Speedo wobbled + - 20 mph at approx 40. Now it goes from zero to opp end. Have checked cable from g/box end & feels smooth. About to remove head to have a look. Cable seems to have weird route from head, goes left behind dash and enters engine comp in the near side. Appears to be original route but quite a lot of bends. Thinking about re routing it straight out & crossing over behind engine if cable long enough. Remember reading thread re head repair man but cannot find it now. Any ideas very welcome.
Pretty sure that's going to be a sticky cable -and the criss-cross route. But could be the drive gear in the gearbox has come loose - although that would more usually give pretty much complete failure. Worth checking the head - run it with an electric drill - set to 'unscrew' direction of course.
Well -it may just flood up into the speedo - jamming it all up. A wipe of Moly grease would be a much better ideas -and wipe the top 2 - 3 inches dry at the speedo end.
Hi,
Found a classic car workshop on my doorstep - well 50 mile round trip. Removed speedo head & paid him a visit. Two days later head was ready to pick up. He had stripped, cleaned & lubricated it. I lightly greased, re-routed the cable & fitted speedo . Road test & not a waver. JOB DONE!! Well pleased.
