    Default 205 Speedo Cable Help!

    Hi All.

    I own a 93 Si and my speedo has always been a bit jumpy, now it's time to fix it up. Has anybody had to changeover their speedo cable and can tell me whats involved?

    Is this going to be a dash on/dash off sort of affair?

    Thanks

    Been there done that! Crap job but you don't need to remove the dash but get in behind it from underneath. It's only a crap job because you don't have a lot of room.

    It's been a while but from memory it's a case of undo at speedo and remove the locking rubber 'cotter pin' at the gearbox (or diff?) and remove the cable from there. Insertion I think is speedo first then the bottom but I don't know why I think that! Possibly to ensure the seating of the cable in the speedo.

    Make sure you seal where the cable goes through the firewall (it has a ball arrangement that seals into a cup thingy in the firewall) or you will get some mechanical noise in the car. IT would be good to be Inspector Gadget at these times if you get my drift.

    My speedo wasn't working and I did this and it continued to not work! Turned out to be the little drive gear in the gearbox (diff? - can't remember/visualise).

    As David said there is a plastic gear in the gearbox that the cable attaches to check this first as it can wear and become sloppy causing a jumpy speedo, the second is the replacing the speedo cable easy, well sort of!

    You have to remove the top cowling on the dash to get at the back of the instrument panel, be carefuly undoing and reassembling the dash as the plastic can crack easily.

    Once you get access to the back of the instrument binnacle simply unplug the cable, then pop the bonnet and pull it through the firewall, follow it down to where it joins the gearbox and pull up the rubber boot and "pop" it just unplugs, plug in new cable and feed it back through the grommet in the firewall, make sure the cable is well away from the exhaust, tie-wrap to air-con hoses on the firewall to keep it well away from the exhaust manifold.

    Plug it into the instrument binnacle, rest binnacle and go for short drive down quiet street to make sure it is working, if working re-assemble dash...curse Peugeot engineering have a drink

    Yep, That's the easy part if you don't mind the grease and crap falling into your eyes as you do it - you're under the car so you will need some stands. There are different sizes (read number of teeth) so make sure you get the correct one.

    That'd be bloody right - I would find the hard way to do it!!

    Do you really need to replace the outer casing as well as the inner cable. If you just replace the inner cable you can do it once the instrument binnacle has been removed. I suppose if the plastic gear needs replacing you have to get under the car.

    THe outer casing and inner cable come as one from the Pug dealer... you do not need to replace the plastic gear in the g/box, but it worth checking especially on cars with high k's
