my speedo is out by about 20ks, if it says 80 its more like 100. how do i change it myself or will it cost much for a guage place to do it

im not a gynecologist, but i'll take a look for ya

im not a gynecologist, but i'll take a look for ya

It depends on what sort of gearbox you have, if its a m20 or trimatic you can change the gear on the cable but I don't think it will alter by 20Km/h. It sounds like you have a speedo fault, to reco a speedo would cost about $50.oo

Hi speedotom. How do you get a HK tacho out of its housing and then how do you remove the glass?

I'm not sure how they come out of the housing, I guess there would be a U shape bracket behind the tacho, try removing the centre console and looking underneath it.

To remove the glass is a bit difficult, it will have a chrome bezel that holds it in. The bezel has to be carefully prised off without damaging it to much, once the bezel is off then the glass should come out.

If your not sure I can do it for you.

Yes I do. If it still hums then the electronic side of it is working, the movement may be jammed or worn.

If I can't repair them then I can fit a quartz movement and retain the original dial and case.

This cost around $150.oo

Hi Tom
I have a Supra box behind a 202 ina LH Torana. The speedo runs about 10% slow. The speedo cable is a Dellow conversion unit which runs a Toyota gear. Where can I get a Toyota gear to give more accurate readings? Will I have to replace the driven gear in the box as well?
thanks

I normally fit a ratio box, this is the simplest solution, it will correct your speed and your odometer in one go.

I sell them for $130.oo

I have an interesting tacho issue.

Tacho is reading too high, especially down low close to idle.
a normal 800-900rpm idle shows up as 1200rpm. At higher revs it seems more accurate (or possibly just less noticable). Tachno is original fitment and has never been tinkered with. Switch on back set to 6cyl.

Model: HT
Engine: 186 (With 12V blue ignition)
Tacho: HT GTS dash, GTS tacho.

Also the tacho needle travel is not linear. 1000-2000rpm is smooth and even, but it seems to move faster from 2000-2500 before slowing down again to normal. Is this fixable?

Thanks

Sounds like the tacho movement is out of balance.

It may also have something to do with the different ignition. I haven't had one to fix for a while, I will fit a 10K resistor on the tacho wire to suppress the signal.

If that doesn't work than it will be the balance.

This can be fixed, it will cost about $50.oo

You can check in the online Yellow Pages.

Is that the price fitted? If not, how much to fit and calibrate?

I'd really like one of those ratio box thingies for my supra 5 speed and the subsequent 20% error and the 6 points off my license for doing 65km/h just outside of Lismore city limits on an Easter long weekend. I think it would pay more itself immediately.

does that allow you to run a aftermarket speedo?

i have just put a 3.55 diff in my VK commodore and now it says i am doing 140 when i am doing 100.

looking to fix it but would prefer to ditch the drab speedo and go something new.

Speedo Tom,

Firstly welcome to the site Tom. It is good to see a new member offering there help. I am sure you will be flooded with requests.

I have a HG brougham and have fitted an electronic dizzy and now my tacho is out (HG GTS dash). I have checked the 6 - 8 cyl switch on the back and it is on 8 (I have a v8).

The tacho is out by a bit (says I am idling at 1350 when it's more like 750rpm) and i am wondering how to fix it. I have been told on here before that there is some difference in the output from the electronic and points dizzy's but I am unsure how to rectify it.

It doesn't seem to be going crazy and seems to be out over the entire rev range. Is there some kind of adjustment on the tacho needle or input signal thingo that can be used to calibrate it??

Cheers,
Adam. (HG Bro)

Try a 10K resistor in the tacho wire. Also check on the back of the tacho for a trim pot, its above the cyl 6-8 switch and near the word PINK.

If this dosent work you might have to change the printed circuit board inside the tacho.

cheers speedotom

Hey mate

Ive got a T700 in my WB (Behind injected 355)

Running a CRS transducer unit and custom speedo cable to original speedo and its currently running about 10k's higher than it should be.

I have 17x8 rims running 255/40 tyres and previously was running 235/60 14's and was running at the same amount out so that hasnt seemed to effect it.

Now im taking out the salisbury diff this weekend which has a ratio of 3.36 (open centre) and will in the next few weeks be fitting a Ford 9 inch from a XY falcon will be going in with 4.11 gears and centre will be locked.

Will the steep ratio change effect the speedo and if so what can i do to correct it, taking into account that i have the pulse converter thingo on?

Cheers

Changing the diff ratio will alter the speedo reading, going from 3.36 to 4.11 will reduce the cable ratio speed, but I think it will alter it more than 10Km/h.

I not 100% sure maybe someone else can help with the ratio difference.

cheers speedotom

What can I do to fix the difference?

You can fit a ratio box or get the speedo calibrated.

The ratio box will correct the speedo and the odometer, just calibrating the speedo only corrects the speed not the odometer.

Hi,

Have got a 350/ TH 350 in my HQ stateman, it runs 2.78 gears. The speedo needle bounces around sometimes, sits nice and 'still' sometimes, reads way low sometimes and doesnt go at all sometimes.

It has a new cable from rare spares and new gears from a gearbox shop. The speedo worked fine with the 308 / trimatic.

Have u got any ideas?

cheers mate
devilly.

Thats a hard one.....

Check the new cable for sharp bends or kinks.

Check the speedo end and make sure its connected properly.

Does it have a cruise control unit on the d/s inner gaude, I don't think the HQ's had them but they give a lot of trouble.

cheers

when fitting a vs fuel injected v8 to a hz will the gts tacho work fine?? or will it be incorect? i think mine is incorect but havent tested it. i was told that the efi eng requires the tacho to be redone.?

I don't think the tacho will be accurate, I would recommend fitting an after market printed circuit board to the tacho original movement, this will also keep the original dial and needle.

Hey, just wondering if i will hav to take my speedo to an istruments palce.... The speedo needle is stuck on around 60km/h even wen cars stopped.. It stays stuck bt randomly jumps and moves erratically around, goes to 80, then all of a sudden winds all the way to 200km/h.. My car is a Vk com with very mild 202 n 4 speed..

Another question is that wud u b able to supply me with a wiring diagram for a shift light tacho?? Please

Cheers, Sam

Yes, a very common problem in the VK speedo's the actual speedo frame bends and the movement is misaligned, it will need a new frame or if your careful you can realign the old one.

sorry I don't have a diagram for a shift light.

Again, welcome to the site.

A speedo calibration question - I have deduced that metric old holden speedos are calibrated 100kph = 1000rpm of speedo cable ... is that correct ? What is the cable / reading relationship for the imperial speedos ? I am using this info for an online calculator I intend to upload to Holdenpedia.

I have a hx gts tacho which works intermittently, I am running a HEI ignition at the moment but it was doing the same thing with points and Bosch electronic dizzy. The auto-electrician at work tested it and couldn't find a fault with it. I have tried fitting new wires with a good earth but nothing seems to change it any ideas ??

The HX tacho's have a problem with the internal coil also called a choke, it may have a broken wire.

They can be repaired but are very time consuming for around $60.oo.

Hi, I've got a Toyota Celica 5 speed behind a 186 in an EJ with 13 inch rims. It's reading nearly spot on 20 k's out. It reads 100 k's but i'm actully doing 80 k's. Can it be fixed easily and how much?
Thanks in advance Shannon.

Yes it's fixed with a ratio box.

First I have to do a 'cable count', this tells me exactly what revs are coming out of the gearbox, if you're confident that you know how far out it is then the 'cable count' isn't necessary.

Then I order a 'ratio box' which bolts between the gear box and the cable. (you need at least 3 " clearance)

The 'cable count' is $60.oo
The 'ratio box' is $130.oo
The fitting is free
Total = $190.oo

This corrects the speedometer and the odometer.

OR

You can just have the speedometer calibrated but not the odometer, this requires the speedo to be removed and adjusted, this will cost around $50.oo - $60.oo if the speedo is out of the car.

I do a lot of repairs through the mail.

cheers
Tom

HI, i just dropd a Aussie 4 speed out of a VK into my VK. my VK had a auto box installed in it, even tho came from factory with a MC6 box, i have used same cable from auto box and my speedo is playin up, i have swapd cluster over and now this one its out by say 20-30 kays, speedo says 40 but im doing around 60, speedo says 50 im doing around 80?

Do u think changing my sppedo gear will fix this, is so what colour should i get.

i got a GU5 axle, looks same as VL diff dunno if its a 3.45 tho???

Thanks Damo

your problem is with the speedo drive if u never changed it from the auto one.
if i recall i used a red colored gear for the aussie 4 speed in a vk but correct me if i am wrong.

u have an 85 vk which has a 3.08 borg warner diff

Hey mate thanks for that, well ive been told me mate put a red speedo drive in (he fitted the speedo for me) but is there a different red one for manual and auto??

the speedo is deff out by 20kmh, there wouldnt b a problem with my cable would there speedo goes fine. what do i ask for when i get a new speedo drive, how many teeth and where 2 buy from?

Thanks alot damo!

these are the speedo specs from my manual.
you need the m20 to have a brown (7tooth) speedo drive gear(inside gearbox), and a red (18tooth) driven gear (on speedo cable), running either 175/75 14's or 205/60 15.

there was to reds a 4 speed gear 18 teeth, and a auto one 23 teeth.

depending on how many teeth is on the drive gear u could match the driven gear to siut instead of pulling the rear housing off.

Hiya, I dont know if you can help...our bedford TL 750 B reg horsebox has just failed its MOT because even though its tacho exempt, they couldnt read the calibration date, so we had to get it recalibrated but when we went to get it recalibrated, it turns out the tacho doesnt work which affects the speedo etc. I dont suppose you know what our options are? Or if you have ANY advice!!? we're not having much luck in finding a replacement. Its a Veeder root 1200/1400 tacho which is electric from the box. Ooh and i'm in the UK if that makes any difference to our options? Thanks in advance if you can help in any way, Sam

I would enquire as to the legality of replacing it with a aftermarket item. There are many availiable that would suit this pourpose.Most of the auto accessory shops over there stock them beacause they are a favorite addition for boy/girl racers to add to their 1 litre car to make it look sick .It would only need to be a temp item to get it through the MOT. Wierd system that one of yours. Got me stumped why you would need to have something calibrated that you dont need to have.(on a lighter note you may be better riding the horse cause it will probably go faster than the bedford anyways.)Did anyone mention the cricket.

I had this issue in a VN. The speedo would drop out intermitently, stick on 0 when you took off, then bounce to about 120 km/h when you got to about 60 before settling, sort of, on your actual speed...and the odometer only recorded about a third of your actual K's...

It was the connector behind the speedo. It had that green, grungy electrical growth stuff on it. Pulled it off, cleaned up both sides of the connection, put it back together and it worked perfectly again (well, as perfectly as a VN speedo can...).

Hi Speedo tom,
the speedo(and odo) on my 5 speed VN started behaving erratically about two years ago, wobbling around, dropping to zero, and then returning to normal service, until eventually it gave out altogether. i rang around until i found an auto elec who would look at it, who 'tightened the pins' for 300 bucks and it worked for another 5 months until exhibiting the same symptoms as before. ive seen forums describing a broken cog on the speedo, but this doesnt sound like it fits the symptoms. any ideas?

I really cant afford to go to them and they will charge me $200 and then say buy a new one or some crap. I have sent you an email also I really need help here.

Hi Ian, its a good idea to open a new thred with a question like this......there is nothing wrong with what you,ve done...its just that not everbody see's it :)
I am hoping that a couple of members on this site may see this post as they were around when the Van Craze was in full swing, they could have the answer.
Failing that, try this.....pull the glass off the speedo and hook it back up, grab a mate with a sat nav and go for a run out the road, mark the speeds on the dial 60 kms, 80, 100 etc.
Take the speedo to a sign-writer, he should be able to make a nice vinyl sticker to go on your speedo, using the marks you made to put the numbers in the right spot.
Cheers,

I am planning to use a VZ cluster to show the temperature of different places in my new pizza oven. Considerable intermediate electronics are in involved. i need to know what frequency and drive level is required to drive the speedo and tacho to full scale.

My low KM wl statesman odometer isnt working.
My question is if I replace the cluster will my old Kms be there or will it be the new Kms

K's stay on the odometer, so it will read whatever is on new cluster

Hey what do I need so original vl speedo works with t5 cheers

my digital odometer is not working on my vn commodore, it is a stage 3 instrument cluster, all the rev gauge and the fuel and temp and speedo work but not the digital odometer, any idea's how to fix the prob as the display is blank

check your fuses first.

ok mate i'll go and check, but i'm pretty sure they are all good

checked the fuses and as i thought they are all good, so i'm at a loss what is causing the problem, as it should be working but the display is still blank

Did you check all the fuses?, there is one that shares for the cluster and something else. Check the plug is in the bottom of the cluster properly, you might be able to see the plug from under the fuse panel. Otherwise you may have a dead display.

the car has never had a digital cluster in before, so i'll need to locate the plug for the bottom of the cluster,it looks like it might be a fun job just locating the plug for the cluster

going from a stage 1 cluster to a stage 3 looks like a very time consuming effort just trying to locate the plug for the bottom of the cluster is being a right pain, the plug must be tucked right behind the cluster housing, aarrgghhh

That would be your problem, you can't just put the level 3 in. Search for a work guide on just Commodores.

some help to fix speedo and does any one have vent cable's plastic pull tag's broken

Got the speedo working after a couple of years without it (just reseated it). But the ratio is out of whack. For example: 20 on the speedo is 20 in reality, but 25 is 30, 30 is actually 40, 35 is 50, 40 is 60 and so on to 60 on the dial actually being 100. The speedo goes up 5km for every 10km increase in speed. So I can accurately know what speed I'mI'm doing but wondering if it's gearing or something?? Thanks.

Hi.

I have a Saab 9-3 2006 model which has a really annoying problem. Whenever there is power going to the main instrument panel, it makes a constant, high frequency sound of around 17 kHz. It is constant regardless of having the engine running, key in hand or anything else. I have traced the sound to the four dial engines inside the speedometer, but I dont know how to fix it. Do you have any experience with such an issue?

I've tried to replace it with another instrument but it had the same sound. I also sat in a different 9-3 2006 mod and it had the exact same sound so it seems to be a common fault amongst these cars, although from a very small sample size.

Here is an image of the four parts: https://www.dropbox....

A&P PAT 050513 2626 Ver 3.0.G(I think its G, was a little blurred)

Hoping you might have a solution.

Hi I had 3.73 diff gears fitted to my VN Calais . my problem is that my speedo is out by 15/20 ks when traveling around town but on the highway it climbs more every 10k incriments . and also my odometer is turning over a lot quicker

Hi mate.
Been searching but cant find any post similar to my issue but my speedo reads zero until i get to 70-80 then reads 110kmh and 120kmh when im doing less than 100kmh.
Advice on what you think the issue may be would be much appreciated and save alot of time continuing my search on forums and money having to take it into a workshop
Cheers Jay

Hey tom, some of the pixles in my digital display screens in my vn calais are stuck on permanently effecting the display, can this be fixed? Are the kms stored somewhere else? If they are I should just be able to change out the screens? And also my speedo isnt working at all

Thanks heaps, zac

Hii , i have a vp and the speedo bounces and sometimes sits around 5km , what could be the problem?? Thank you jack

I have had trouble with the digital speedo on my VN commodore...
Tried everything...so has an auto electrician...to no avail....
Do you have a digital speedo conversion to mechanical, or know of one I can purchase so as to relieve me of this incessant bother....I don't mind mounting an mechanical a speedo on the dash if that is what it takes...Cheers Llew...

Maybe you need to find a new auto elec. what's the problem?

My tacho stopped working recently. The speed alert & speedometer still work, just not the tachometer. any preliminary quick checks i should do before i pull the housing apart?
