View Full Version : Rolling Back An Odometer Question *Read Before You Judge*

Okay yes this is an illegal act if it is your stock gauge cluster and you try to "trick" a buyer into thinking its less miles/kilo than it really is, but mine is for a completely different reason!

I bought a set of glow gauges a while ago as well as a 92 GT Gauge Cluster from Dave so I could get these installed, now here's the thing:

The current milage on the 92 GT cluster is far past the odometer on my GTS'. The GT reads approx 142,XXX miles where as my GTS is 214,XXX Kilometers.

I would like to roll back the GT to equal the proper amount of miles which reads on my GTS cluster.

Is there anyway I can go along doing this without damaging the gauge cluster or is this just a false sense of hope? If anyone has any VALUABLE information for me this would be GREATLY appreciated.

you could probly just open up the clusters, take the speedo from the GT-S and pull out the roller with your reading on it and swap it with the other one. it all comes apart. the rollers inside of it have a locking mechanism so you cant roll it back you have to go foward or risk breaking by trying to pull all of them apart. the easyest idea id see is try to swap the rollers from the speedo's if they fit.

I've done it before, easy to roll em back. How I did it I don't remember. I did it when I got a new gauge cluster.

There's a shop out here that does that. They quoted me 30bux to roll back. I almost bought a digital cluster for Celibaby.

My understanding is that you unhook the speedo cable and lock it into the drill where you'd normally put the drill bit. Then set the drill on reverse and spin away. Keep in mind, I've never actually done this, so proceed at your own risk. I think the speedo gauge swap might be easier or safer....?

I did it to a delsol gauge cluster (my buddy bought a pars car) and I was messing with it, used a screwdriver and just pryed them back, the paint on the numbers comes off way to easlier, and i think it broke it as well.

i've done this with one :D shhh.. lol not for illegal purposes... on a restore... and wanted to rebuild the title... actually i didn't do this... someone i was talking to was like "wanna see something cool?" lol and than he showed me... but this is how we did it

This possible then? Can anyone confirm? Itd be a lot easier to just swap the rollers IMO.

Ok here we go im just gonna take it from the top i dont know how far youve discected your gague pod.... so here is the speedo removed and the gague face taken off. your going to be left with this. There are two skrews nexto the needle holding the face on. you can take it off for more access.

what you want to access are the two clips here holding the "Roller" in place. The problem here is toyota didnt want to make it an easy task on us so it looks like a brittle plastic clip that has been melted in the middle, best idea i can think of is , find a way to warm the little end maybe melt it off or bend it apart if your going to plan on melting it backtogether. other than that i would suggest trying to cut off the clips from one side, find a VERRY small washer that fits the shaft size of the roller, using some type of epoxy to remount the washer so it holds the roller the way it was soposed to go.

Good info, dude.

ok update.. i got the roller out!

all you have to do is take a razer and dig out the top of the right clip, where it is melted together so that you can see the top of the metal shaft the roller works on.. then goto the other side and only cut off the outer side of it that keeps the roller from sliding. then you can push it out the one side, and when you goto put it back in it will just clip into the one you dug out

You don't have to pull the roller out...
Stand by.
I'll get a few pics tonite. I happen to have one apart atm.

Hmm..good info but a little confused, how bout you just fly here and do it for me :)

Might be easier to follow after I get the faces off the cluster.

ATman, if you can figure out something easier let me know!

Actually I just had an idea. Is it easier to roll the odometer forward? Cause then I could just take the GT cluster is roll it to the proper 2xx,xxx kilometers that I need. This a better idea?

Hold on for a bit.
I have to check something first.

This thread makes me question the legality of allowing it to remain open.

Im gonna let it go, but if my research determines it is indeed an illegal act, I will have no choice but to close it.

Carry on guys.

yeah i see where your coming from luni. but the story sounds legit. the GT speedo goes to 120 and the gts to 150. so he couldent just swap the gagues to keep his odo reading or his speedo would be pretty far off.

i had to replace my speedo when it stoped reading on me. the new one started out at 0 so now i have a gauge cluster that reads 14,000 insead of 63k like it should. so i can see how this type of info can be usefull.

one word of great caution is. i tried to take apart my broken speedo just to learn how to roll the new one forward. after i took everything apart, it was almost impossible to put it back the way it should be. so chances are if any of you try this, you could end up with a broken speedo .

Bleh this all is sounding very complicated. And Luni this isnt for illegal purposes, its for if I ever sell the car I want an accurate gauge reading for how many km's are really on the car.

I might just have to check someplace in town if they do any rollback/rollforward on odometers.

Prooooobably shoulda just left the gauge stock and not bought the indiglo, but it adds a nice touch to the interior.

Any luck with anything ATMan? If there is a possibility of rolling this forward it would work too, would just roll it up to 214,xxx km's instead of rolling back to 125,xx miles or whatever it equals.

Sorry.
I had to consult with my fellow mods first.
But The Mighty Lord of CTech said go for it. :D

SO

Ok, to start, this is not to be used to tamper with the actual mileage displayed for your car. It is in fact illegal to tamper with the portrayal of the actual mileage on a car. THIS IS FOR SHOW USE ONLY.

First off, I am not going to show how to remove the instrument cluster, or how to take it apart. At least not in this thread. This is only how to break the od down and change the mileage on it.

Secondly, the parts in this are DELICATE. BE GENTLE.

To start, you will need to GENTLY pry the needle off the pin. Note the pin in the pic. Then, you will need to remove the speedo face. It is held on by glue. Note the 2 glue spots on the facing. Use a razor blade and GENTLY work it under the glue, breaking free the face. If you work it too hard, you will ruin the face.

Once the face is off, you will see the 2 screws that hold the od to the plastic facing. Remove these.

Note the 2 screws sticking up. Remove both. Then remove the 2 metal pieces that they hold on.

Remove this screw as well. Then remove the trip od reset switch.

Now, you can pry the od apart as such. DO NOT pull it completely apart. You only need to get it a little bit, like in the pic. If you pull it too far apart, you will break it.

Rotate the numbers until the clip in the pic is up.

You will need a screw driver or key or such to push the clip off the metal pin. Lift the clip off the od.

You can now separate the rollers, and spin as necessary.

Here's the hard part. You have to align the numbers just right, or they won't line up. Note the pink inbetween the apart rollers. They are teeth. If you don't line them up EXACTLY right, the numbers won't line up.

In addition, the numbers you are looking at are not the ones that will be on the front once it's rotated back. You will need to adjust. There are 2 sets of teeth between the rollers. Note the smaller of the two teeth in between each roller [one is profiled against the brown gear]. You will need to put the number that is 2 lower than the one you want at the tooth.
For instance, say you want the last # to be a 5. You want the # at the tooth to be a 3. If you want the second # to be a 9, you want the # at the tooth to be a 7. If you want a 1, you will have to set it at 9. So on and so forth.

Actually believe it or not this is a completely LEGAL act in the USA as long as the vehicle being rolled back is 10 years old or more. We discussed this many times in a few of my Auto classes and alot of teachers all said it was legal and was used mainly when restoring old cars.
