Speedo sender repair.

[stevierst]

The Speedo on my mk1 gave up the ghost on my last rideout, apparently a fairly common thing where the front wheel sender lugs wear out and no longer lock into the wheel recesses.

With me being a notorious tight arse, I thought I'd have a go at re-manufacturing it to see if I could get it working again.

I stripped down the front end and took out the sender to find this, a step worn into the sender lugs rendering them useless.

I know I can repair this using build up materials, and set about it by using a piece of electrical tape to make a 'mould' for the material to sit in whilst it cures

I tried using chemical metal from plastic padding, but it became brittle and wouldn't stay in place. I decided on trusty old araldite as the filler, and put enough in to fill the 'mould'.

I left it for 1/2 hour to cure, and went for a brew.

I came back to it and removed the tape to find the araldite still fairly soft, so I gently trimmed off the excess with a knife and file to get the original profile back.

I know it doesn't look pretty, but its only a repair until I can get a new one.

I fitted it back to the bike taking care that the lugs went into the recesses and re assembled the wheel.

I left the bike for another couple of hours to let the araldite fully set, and then tested my 'bodge job'

C'est Voilla! It works! For how long, I don't know, but it works.

If you need a fix it job for a knackered Speedo drive, this works for now. I'm going to keep the bodge on the bike to see how long it lasts as an experiment, ill keep you updated on its progress.;D

Wear out???
I doubt it, they normally get fitted without the lugs in the right place then snap when you tighten the wheel nut!

Actually, ignore my comment, i've just seen what you mean by the first photo.
I stand corrected! Can't say i've seen that before though!

 Yep I can vouch for that

Well there's definate wear on mine which has made a step on the lugs somehow. I know it was put back together right when I last changed the tyre, as I've had one break before due to my previous incorrect assembly.

This must be a freak one then. Weird!

Yeah, i can't actually think how that can get like that?

[stevierst]

Mr neither, but its happened. The repair has held out for 200 miles so far. : probably cursed it now!

I can vouch for that, mine has had this exact same repair from a previous owner of my bike and ive never had a problem..
