vl speedo out due to different gears.
 
Hey guys

Just got my Calais back after having some 4.11s fitted.my speedo is out by 20ks just wanting to know how I'd go about fixing it?

I'm using an r33 gearbox.

Thanks Scott.

you need a speedo adapter. Last I recall the rod shop (castlemaine rod shop?) used to sell them. perhaps give them a call and see if they still do.

Your gearing is out, as far as I know there realy isn't an easy or cheap way to change it because it's all mechanical. the adapters were over $100 last time I checked.

Thanks for that I'll give them a call this arvo and see how I go!

TheChad 24-11-14 17:40

theyre over east so you'll have to give them a call in the morning.

Scott there's a mod you can do to your speedo drive using parts from an R33 electronic Speedo drive, I'll find the how-to link tomorrow.
PS, how does she go with the 4.11's??

skoota 26-11-14 12:44

Hey Steve that would be great!
The 4.11s have really woken the car up, it is a lot nicer to drive around town now. I also replaced all the rear bushes with super pro bushes and they have made a big difference as well.

We will have to catch up when you get your car on the road! Are you far off finishing?

TheChad 27-11-14 13:44

Steve I went through all that before, the 3.9 (3.89) and 4.11 come from SR boxes from memory, the drives are much shorter so not a direct bolt in. **** me if I could figure out how to get the plastic gear off the drive without completely rooting it, would love to see a step by step of how someone's done it.

skoota 27-11-14 14:53

I've ordered a gear from an s14 speedo drive that is a 4.11 ratio. I'll see how I go fitting it once it gets here.

TheChad 27-11-14 15:30

oh bummer, I'm 80% I've got one in one of my parents garages, you could have just had it.

Let me know how it goes because I might have a shot at it myself.

skoota 27-11-14 15:48

Haha that's always the case. Cheers anyway! It took me a whole to find the part.

I'll keep posted once it arrives!

if you get stuck go to flexible drive in welshpool. a few doors up from the dutch butcher. they do custom cables, gears whatever you want. well priced too.

Steve 28-11-14 10:02

Sorry I've been busy with work and havent found the link yet.

Jack, its using RB parts not SR parts and works fine. The black cog on the VL speedo has to be destroyed to remove and you use the red cog from the RB25 speedo drive. Little bit more to it though.. I'll find it soon...

I havent touched it since you last asked me haha - I've been on too many Holidays this year :D




Well, while searching for the info I wanted, I found this instead:

Ring Nissan and see if they can order you a pinion drive p/n 32702-31G20

Heres a list of speedo drives to suit different diff gears.

32702-31G21 21 teeth (PURPLE) Ratio 4.375:1
32702-31G20 20 teeth (RED) Ratio 4.11:1
32702-33G19 19 teeth (WHITE ) Ratio 3.90:1
32702-31G18 18 teeth (BLUE) Ratio 3.70:1
32702-33G17 17 teeth (BLACK ) Ratio 3.545:1
32702-33G16 16 teeth (YELLOW) Ratio 3.364:1



The other info I've seen in the past involved machining the end of the VL speedo drive shaft to look the same as the R33 shaft once the circlip has been removed to get the red gear off.
Then you need to cut a grove in the other end of the drive housing as the gear is offset in the housing so its not too tight in the box.
These part numbers for the complete assembly including the required gears means no machining required.


EDIT:
Found some conflicting info, seeing as the VLT/Navara Speedo drive p/n is actually 32702-02G17 (I've bought and used of 2 these now - one of which is in your gearbox now, Scott)

If you ring Nissan, see what the first part number in my post is and then see what 32702-02G20 is...

I have a feeling the first PN's in this post are for 4x4 model Navara's and these are to suit the 2wd D21 Models, which have similar box to VLT/R33

32702-02G21 21 teeth (Purple) Ratio 4.375:1
32702-02G20 20 teeth (RED) Ratio 4.11:1
32702-02G19 19 teeth (WHITE ) Ratio 3.90:1
32702-02G17 17 teeth (BLACK ) Ratio 3.545:1 (VLT)



Cheers
