How do I correct my Nismo odometer?

[halfjap1980]

Hey guys,

I have searched all over the net and can't find anything useful.

I just picked up a Nismo 320 km/h cluster for my R32 GTR. My car just broke 100,000 km last week and the cluster I bought has over 137,000 km on it. I tried using a drill to spin the odometer in reverse and it was working...until I got to 137,100 km and then it stopped. The trip meter still rolls back, but the odometer won't go any further. Is there any way to get around this? I'd hate to have to wait 37,000km before I can install it. It took me almost 4 months just to go 5,000 km.

Any help would be great guys!

Thanks!

Not a good idea to spin the dials. Note km on old dash, note km on Nismo dash and keep somewhere, give to new owner after you sell car. Most install new Nismo dash with 0 km on it. Or could take to speedo specialist.

Dude, stop it, now. You could of screwed up that Odo big time lol.

Like going over a pothole and your kms roll back screwed up. If you shake it and the numbers are still solid, you're probably fine though.

When i bought my Nismo gauge i had the same problem. The only difference with me, is that i had broke my stock speedometer and the base of the nismo gauge was broken as well. we tore everything apart on both gauges, using the stock base and built the nismo dials up from there. while we were doing it, we changed the odometer with a small mini screwdriver.
I'm not sure what damage you could have done already, but you can try this. Keep in mind you will have to get the computer checked out and match the new gauge with the actual speed of the car.
I haven't had any issues with my install other then not matching the speedometer with the actual speed I'm traveling. Just haven't had the time to do it.

Ya I gave up pretty quickly on this cuz I didn't want to break it. The odometer still rolls forward when I spin it the other way. Just got to install it and see if the speed is correct with my GPS. The last cluster I had was a MiNE'S cluster and it was off by 12 km/h hopefully this one will work better.

If anyone else has any ideas though, please post them up.

Thanks again guys!

Not a Skyline but the odometer are similar in design:

I was thinking of trying to pull that pin out, but I would have to bend stuff and if it didn't bend back properly then I'll have wasted $300 bucks. I'm just going to have to make note of the "original" km's and the new km's so I can show it when it comes time for resale.

Thanks for the help guys!

You could try taking the odometer apart and changing it from there, but i'm not sure if i would do it myself.

Does anyone know of a shop in the GTA that could calibrate and adjust the odometer on a mechanical speedometer? I'm guessing A domestic shop would probably be best. Any ideas?

Thanks!

Youtube has a two part instruction for a Toyota pick-up, same idea and quite detailed too.

Ya I saw those clips, but the metal clip that holds the pin on the top of the odometer is bent in on the one that I have and I don't want to try and force it since I've never done it before and don't want to break anything. Better to pay some money and get someone experienced to do the work.

I just have a good look at my spare odometer and it's easier then the video. I just used a pair of wire cutter and gently pry open one side of the clip. Lined my number up and tape it with a piece of tape. Now the tricky part is that those white gear has large and small taps. I didn't count then but I would say 5 of each (0 to 10). The number 7 is where the large tap get to hook-up with the preceding number. In my case I just reset to 0 so I just line the square part of the gears and the small taps to fit between the rolls. , but I don't think it matters as long as the tap doesn't rest on a 7. After I reset the odometer I just used a pair of pliers and gently clipped the shaft. Hope this make sense as I'm replying under the influence of alcohol (it's darn hot here in Vancouver!..more beer please)

I was bored last night so I decided to try what you said and it worked!

I used a small flat screw driver to GENTLY open that clip just enough for me to pop one end of the pin up. I was able to adjust the numbers I needed and now it reads 101,000 km! Woot!! Held everything in place with my finger while I put the pin back into place. Had to do it a couple times to make sure the teeth of the gears lined up properly. Used a pair of needle nose pliers to close the clip. You can tell that the clip isn't as tight as it was before, but everything is solid.

Now all I have to do is wait for my LEDs to arrive from StreetFX and I'm ready to go!

Thanks for all the help guys!
