I'm replacing my broken guage cluster with another one with about 1,500 less miles than mine. I want to roll it back up to the correct mileage. How would you do this, or is it even possible?

 

3 ways that I know of.

1. the dealer
2. a speedometer repair shop
3. if it's a mechanical guage, disconnect the assembly from the transmission and attach a drill to the cable end. spin it up slowly until you get to where you want to be.

FYI - I never checked the cable on the Camaros. I had a car years ago that I was able to unplug from the tranny and the wire was visible inside the connector. The tranny just spun the wire. I don't know if the 700R4 is the same or not.

 

Once you remove the gauge from the cluster, there will be an electric motor attached with a couple screws... You can remove that motor and access the gear that it turns (which then turns the odometer)... I wish I had pictures, I could have done it on my firebird 140mph unit when I upgraded (I'm assuming a similar design on the camaro electronic unit).. You'd just need to turn that gear (might have to fab something to turn it at a reasonable rate or just be a patient dude..

 

ok this thread just gave me a stupid idea.

i know it wont go backwards, but i wouldnt mind having it back to zero when i put the new motor in.

when i switched it to SC tags, i also reported the odo as inaccurate, so no worries there.. and i could care less about carfax...




so heres the idea..


take the cluster out and put power to the correct pins... then take a VSS and chuck it up in a drill... get it all set up, and then run the drill for.... hours i suppose.. i'll assume 110mph at drill speed.....

lets see:
999999 - 125000 = 874999
874999 / 110 = 7954.53
7954.53 / 24 = 331.43875

so id only need to run the drill for 331.4 days and it would be back to zero. :lala:

 

Would it be at all possible to hook electronic gauges up to a parallel, serial, or lpt port and emulate a signal from the VSS?? That sounds much better than hooking it up to a drill for a year. :P

 

i donno... but even if you ran it at 4 times that speed (440mph) it would still take 82.85 days to roll around.

its not a elegant solution.. more of a joking solution... that could help 25THRSS with his problem, but pretty stupid for mine...

hed have to do it at around 100mph for 10 hours or so. not tooo bad.

 

Mr. Dude, props to you for having the ability to bring a math equation into every thread. You think too much.

If you do that and the drill survives, please let me know so I can go out and buy the same drill. I had a 3M cleanup wheel on my old drill and after 6 or 7 hours of non-stop suspension cleaning-- it caught on fire.

 

lol uhhh, thanks i think....

and yea, i had a cordless drill that you can plug into the wall with this pesudo batterypack... after a few hours, i melted the plastic housing.
