speedo cable replacement

Post  MrNutt on Mon Oct 29 2012, 19:54

ok stopid question alert!


my speedo has recently died , so I assume that its likely that the speedo cable has gone?? ok this is the stupid bit, the mileage counter and trip have also stopped, I assume that this is also ticked up by the speedo cable?

ok next bit, given I am a bit of an idiot, how easy is it to replace a speedo cable (if anyone has done it before?) I have a haynes manual, I have tinkered with a few things, I did my own oil and oil filter change at the start of the year, Took me all day so thats my current gauge of how hard things are to do!

thanks in advance

Quite a simple job. You have to get to the back of the instrument cluster which involves removing the screen and a couple of infil panels.

I think ur upto the job.

If u get worried ur welcome to ride up with the cable this weekend and I will help.

First of all, check that it isn't just that the knurled nut at the bottom end of the cable has come loose so the inner isn't engaging with the drive unit. Happened to me once after a tyre change (funny, that), so now I always nip it up with pliers.

Just the right shoulder that I am having problems with. It's getting better and my Company bought me a year at the local Bannatyne's so with the help of my trainer Ben it's starting to feel a bit better, still can't do shoulder presses yet but the Steam room, Sauna's & Jacuzzi are all helping! clappy

They have TV on some of the cardio - choose your own channel! I normally do 10mins on the bike but because MotoGP was on I did over 35mins, I could barely stand when it finished!!!! blind

The eye candy isn't bad either! naughty

** Stupid answer alert Very Happy **

Best to check that the cable has in fact broken.

I've been through several speedo problems and none of them were due to the cable. I seem to be heavy on the speedo pick up gear and the tabbed washer which drives it.

Guess there's a few ways to check if the cable is OK, I chose the lazy method of hooking up a drill to the cable (front wheel end). Might be a bit tricky operating the drill and looking at the speedo, but the odo should have moved.

thanks for the other idea steve and bobh, I will have a look around the bike this week, though might just take it to a spanner shop, one of the exhaust headers is bleeding ever so slightly too so might need a new gasket in it to.

for the sake of an hours labour.....

Easy enough job if you look at it with a little logic Dave, Nip the header nuts up a little Dave, it should stop it

I had the same problem, I did the drill check method which showed all was fine with the cable and speedo, when I took the wheel out I found the tabbed washer was minus its tabs. Whilst it was out I took the drive gear apart and cleaned and greased it.

Does your spanner supply and fit, or can he just fit? Mine prefers me to source my own non consumable parts and give to him to fit. Keeps the cost down.

I'd still check that the cable isn't your problem. If it does look like it's the front wheel internals the tabbed washer is about £3 from Mr Yamaha and has the strange name of a 'clutch meter'. In my experience it has broke because the gear has siezed up, a new one of those will be £50+ you could be lucky and get away with a clean and grease like nicko600

This happened to me too, It was a quick road-side fix in the next layby

Mine completely undid at the wheel end, the cable lifted out and the internal square drive wire is now decorating a verge in Gloucestershire somewhere. I assume you'd have noticed if the cable was detached.

That said, if it's a broken internal wire and it is broken at the wheel end, if you can get the bits out you may be able to simply run a new internal wire into the existing outer casing in approximately 30s flat. Sadly Yamaha don't sell just the internals, so I have a spare outer cable somewhere!
