So first wee modding/tweaking of the 4.2 Safari :sly

One thing I had noticed on the drive home was that the Trol's speedo was reading up to around 5 mph low compared with gps.

Obviously she's running on larger than standard tyres (33s) but I was keen to do what I could to fix it.

On checking the Aussie Trol forums this seems to be a common problem with Y60 Trols and there's a fairly straightforward solution it seems. Within the instrument panel there's a potentiometer which can be adjusted... if you're brave enough to drill through the instrument casing :eek:

So you'll need to remove the steering wheel and steering column casing then unscrew the instrument cover (I didn't bother unplugging the switches) and finally unscrew the four screws on the gauge unit.



Manoeuvre the the casing so you can get to the top above the speedo and then carefully drill a 5mm hole...



If you've got the right place you should see the crosshead for the top of the potentiometer, turn clockwise to increase the speedo reading (ie get it reading higher)... be careful though as the crosshead is very soft and thin screwdrivers very sharp so try not to butcher it like I managed to :doh



I left the casing loose, refitted the steering wheel and went for a drive to check the speedo vs the gps then re-adjust.

Once you're happy just refit the casing :thumb2

The speedo now reads about 3 to 5mph higher than gps at 30mph (ie gps speed about 27-25mph) rising to about 7mph higher when you're at 60 (ie. Gps speed about 53mph). I'm happy with that, gives good leeway as the speedo is a bit lazy anyway (being 27 years old) and it gives scope for larger tyres again if I should want in the future :thumbs

Ease off moaning myrtle :rolleyes:

Am I annoyed at warping the crosshead? Yes, but it wasn't intentional and I wasn't being careless it is just very soft plastic vs a sharp screwdriver point

The Trol is in great condition and I intend to keep her in good knick but she's there to be enjoyed not placed in a display case :thumbs

Plastic on those are like plasticine, you'll prob never need to touch it again anyways, I'd be more worried about this equation......diesel pump + 4.2 Trol = no holidays for Rob :lol

:lol Cheers mate, makes me feel a lot better!

It's fine, did a tad over 19mpg on the road up so can cope with that - not too bad for that size of engine and all the mods. I'll still get laning :thumbs

Get some LPG up its nose�� That'll get you a few more MPG s and a whole load more power ��Ideal for all that low down torque :sly
 
I got complete LPG kit for a petrol going cheap, tank,regulator, manifold injector, etc, Rick
 
Robs only mashed up a plastic screw head and we're on page 2 already. This thread is gonna be maaaasive:lol

What else can he do with it :nenau Put an air freshener in ever now and again? It's already been modded to near almost perfection. I think he's just going to jump in and enjoy it for a bit but no doubt some new stuff will be fitted to it somewhere down the line.

We have to buffer the thread out somehow
 
He'll have to source those himself :naughty

I can't help him this time
