Reiny Posted July 28, 2011 Share Posted July 28, 2011 My speedometer has suddenly started to play up. It was totally fine and accurate until this afternoon, however the needle suddenly started to bounce all over the place, hovering around the 30mph mark when I was actually doing 50mph and the odometer only registered 9 miles when in reality I covered about 15 miles. I am also hearing a ticking sound coming from the back end of the speedo. What do you reckon it may be? The cable or is the head a gonner?

western Posted July 28, 2011 Share Posted July 28, 2011 have a good look at the cable gearbox end, these do snap the squared end off & it can cause an erratic speedo. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted July 28, 2011 Share Posted July 28, 2011 I had the blue plastic gear on the transfer box end wear out and had the same effect .... apart from the ticking .... the gear didn't look worn out but I swapped for a spare and all went back to normal again.

landroversforever Posted July 28, 2011 Share Posted July 28, 2011 The ticking sound that youre hearing is exactly what I had... turned out to be the speedo head had gone bang! Solved with some nice shiny Td5 Gauges!! Quote Link to comment Share on other sites More sharing options...
Reiny Posted August 5, 2011 Author Share Posted August 5, 2011 Ok speedometer has been replaced but cable needs to be replaced too. I managed to remove the cable from the old speedometer without any hassle. Just a sharp tug. It clipped nicely into place on the new speedometer with a positve sounding "click" but now it just won't budge. I haven't got enough strength in my fingers to pull it out. How on earth do I get round to removing it? Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted August 5, 2011 Share Posted August 5, 2011 Hi, My LHD 110 had a speed limit warning device included in the speedo cable, which means that the speedo cable is in two sections with the join close to the brake servo. Disconnecting the two sections allows the instrument panel to be pulled far enough out to allow use of two small screw drivers to sufficiently pry open the ridged plastic fingers that hold the cable on the speedo head. Hope this helps. Mike Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted August 5, 2011 Share Posted August 5, 2011 You can get more slack on the cable by releasing the cable from it's clip in the engine bay, from memory to persuade the cable to release from the back of the speedo you need to use a pair of pliers to squeeze the sides of the white plastic part which will bend the plastic release the clamping part of it. Caveat it's from memory so may be wrong Quote Link to comment Share on other sites More sharing options...
Maverik Posted August 5, 2011 Share Posted August 5, 2011 I replaced my speedo cable last weekend, took a few hours. I manged to use a large flat blade screw driver to leaver the back of the cable socket off the back of the speedo head... Quote Link to comment Share on other sites More sharing options...
