Speedometer legalities

[merc-blue]

bugger,
Anyone know where i can get a copy of ADRs so i can read through?
you sure you have to have a odo?

[Rodger]

Here is the paragraph:

18.5.2. Odometers
18.5.2.1. Every vehicle other than L-group vehicles shall be fitted with an odometer which shall:
18.5.2.1.1. indicate distance travelled in one kilometre units (or less) from 1 to 999,999 kilometres; at
18.5.2.1.2. indicate the actual distance travelled by the vehicle to an accuracy of 4 per cent.
18.5.2.2. Every vehicle of category LC and LD shall be fitted with an odometer which shall:
18.5.2.2.1. indicate distance travelled in one kilometre units from I to 99,999 kilometres and
18.5.2.2.2. indicate the actual distance travelled by the vehicle to an accuracy of ± 4 percent

Link to ADR for instrumentation on the ComLaw (Commonwealth Law site)page for more:

The document I have taken info from is at the bottom of the page.

My car predates all teh RDA vehcle catagory, are they retrospective?

[Rodger]

As I understand the vehicle must meet the ADRs at the time of build. Which for all time stated that a speedo and odometer must be fitted into a new car at time of its build.

As long as the car has both it complies with ADRs and from my brief reading they may not even have to work. But I suppose you could then argue that a non working speedo does not meet the accuracy outlined in the ADRs so does not comply.

What numbers does your build plate have on it against the ADR line? If you can go back to the ADRs at time of build then your answer lies there.

Regards

Rodger

some ADR's are considered retroactive IF you make changes to the car..

for example, KE10's came with MPH speedos, they only read to 99,999 on the odo.

if i changed to say.. a VDO speedo, it would have to read Km/hr...

have you driven in a car with a digital speedo? i think they are sucky... you have to concentrate more to see what your speed is doing...
imho, it is better to have needle, so you can see at a glance, how fast you are going, and if you are gaining or losing speed (hard to see with numbers ticking over)

VDO speedos are cheap they have a digital ODO.. and iirc, are ok for ADR's...

if you want to build one, thats fine, but i would not want to risk the legalities of it by removing the original one and/or not replacing it with a legal fucntioning one as well as your device...

.

To check the speed they are easy IMO ie quick glance, but suck if they get direct sunlight on them because you can't see shit

sorry to hijack, but i was thinking about doing just that, do i have to wind it forward to read the same as the original odometer or something?

[merc-blue]

VDO speedo i was quoted almost 400 dollars for
just a base line 3 3/4 inch speedo

[STR8 2.8]

VDO speedo i was quoted almost 400 dollars for
just a base line 3 3/4 inch speedo

what the?
i was quoted just over $200 for a 100mm vdo electronic speedo

I've driven many km's in both, and personally don't see a difference.

One is just as easy as the other.

18.5.2.2.2. indicate the actual distance travelled by the vehicle to an accuracy of ± 4 percent

what if your car is used mainly for burnouts??? It could be 20-30% out...

[Rodger]

Well the outer surface of the wheel has travelled that distance and the motor and running gear has done those extra k's so I guess even doing burnouts the extra k's are recorded. Just no satisfaction of travelling anywhere.

[merc-blue]

But it does specify distance traveled, not how much the wheels have turned, but seeing as most burnout car capable of developing big odo proplems are likly to not be street driven/registerable
i would hate to think how far out the one on my TA22 is, its reads 45000 probly ran through the clock 3-5 times
