Odometer disconnect switch? - For non-dodgy reasons!

[AutotestAddict]

I'm looking for a sensible solution to my limited road mileage policy which is being pushed to its limit by the fun wheel spinning times I spend at autotests/autosolos.  I've found a single grass test run of reasonable length can push my mileage up by a couple of miles thanks to my hooliganism, multiply this several times, and by several events, and I'm losing a significant amount of mileage where I shouldn't be.

I do use the car on the road, so I need a speedo and accurate odometer for road miles.  Is there a straightforward way to 'switch' the odometer on and off?  I don't know if it is electrical or mechanical or how it works, but it appears to be a fairly involved process involving the crucial brittle plastic clips to get at the thing, which isn't something I can really be doing every other weekend and expect it to go back together each time.

Anyone else doing motorsport doing a similar thing?  How did you manage it?

*troll mode engaged* additional savings can be gained with a SORN and a trailer.

but I'm quite interested in how trackdayers deal with this for road cars.

A lot of events require the car to be road legal and arrive under its own steam.

For clarity, reasons for not trailering;
Trailer cost
Trailer storage
Trailor licence
Fun road miles
'solo entry regs

So, about this odometer cable?

Odometer is mechanical - read cable driven.
So if you don't want to disconnect at the dashboard your only other option is at the gearbox.
That's on the left side about half way down the box.
No great shakes to remove it but a) you'll need to blank off the hole in the casing to avoid losing oil and b) the now exposed part of the cable needs protecting from dirt and grit.
Once you get your head around it similar time to changing a wheel but the question is do you really want the faff?
Cheers, Pewe.

Hmm. Ok, so what I need is a tiny little gear box located somewhere accessible. Maybe doubling up on the cables, with a cog between them which can be removed when off road and replaced when on road.

Food for thought thanks.

Could you not just increase the mileage on your policy, surely wouldn't add that much to it for another 1000 miles or so.

It is literally a 5/10 min job to remove it from the gear box on the passenger side, i believe its held in by a 8mm bolt?

I had thought about this, i remember there being a thread like this on that other forum that no speaks of its name...

Call your insurance company and ask them, sure there was a resolution that way.

[AutotestAddict]

I've already pushed the mileage as far as I can, its up to 5k from a 2k standard policy.

I guess having a go at removing it first is a sensible way to go. If it is a 5 minute job and I just need a plug maybe that's not so bad.

Taking the clocks out is a 5 min job. I'd be tempted to do it that way each time.

The only way I can think of doing this would be to do a mechanical to electronic speedo conversion - easy to do with a small speedo reader and a universal electronic speedo, and then wire in a switch on the feed.

You could even series a manual to electronic converter, then a switch, then a electronic to manual converter providing you could find ones with identical ratios, then you could keep your current dash.

Entirely theoretical tho, I've no idea if that would actually work, but the parts are available...
