anyone got a strip type speedometer spare? trying to see if i can convert one to electronic so it will work with the zf gearbox i'm fitting.

thanks craig
 
just send an address and i'll post it off
i don't want anything for it, i just hope its of use to you
regards jules
 
Craig, I live down the road at Garstang and I'm reorganising my workshop, guess what I found yesterday in my spares dept? It's yours if you need it to experiment with. No idea which model it's from, I would suggest an auto looking at the shift marking numbers, and 4 cylinder by the fuel tank sizing, but it isn't suitable for my series 2.

Craig, have you seen the various discussions in the ZF thread about speedo alternatives? I use a Dakota Digital converter to operate the unmodified speedo in my ZF-equipped car. Very happy with it. Which variety of ZF are you using? You will need a signal generator for most, if not all.
 
yes i've read through the threads but must have missed the bit about running a Dakota converter, i thought that was a separate speedo head which to be honest nearly put me off doing the job altogether. it may sound sad but i quite like the plain simple design of the strip speedo so i'm not wanting to put extra gauges in at all.

i will have another look through, on a different tack does anyone know who breaks/fixes up the borg warner boxes? i'm going to look into getting the tail cover of the zf machined to take a mech speedo if i can find a suitable drive worm.

p.s i'm using a jag type zf box.

Sounds like a lot of work to fit a speedo drive worm in the tailcone of the Jag, I am not saying it cannot be done, but it does seem a long winded and expensive option, especially if you have to employ the services of a machine shop.
As Warren suggested, the Dakota digital kit is a very good option, and is a straightforward fit.
If you go ahead with the speedo worm option, then you may have to trim a little off the output flange, so the speedo worm fits on the output shaft, the drive worm would also need to be modified, as the BW 35 drive worm splines does not match the ZF splines.
All doable, but time consuming and costly, you could also use the range rover lower speedo cable, as this has the option of fitting cruise control or other electrical options that require speed inputs.

I have seen it done, but I can't remember where. It was somewhere on the net, but that's a pretty big place.....
 
Here's a link to the Dakota Digital ECD-100. Mine is mounted on the underside of the dash, to the left of the brake pedal, and the connections are all in behind the front speaker, where I pick up the signal from the sender unit (wires come through the old speedo cable grommet) and an auxiliary 12V feed (same one that powers the radio).

I also bought the SEN-4165 sender unit - scroll down the following page:

I hope this helps: I looked at a range of options for the speedo, and in the end this seemed like a no-brainer.
 
thanks for the input folks, i'll agree the Dakota option is the most sensible option all round apart from the cost. easy to fit and as proved works well.

however i am fortunate enough to have access to cheap machining through work and i like the challenge i'm going to carry on with the options I've got so far....(then probably buy the Dakota anyway :D )

Craig

p.s the Dakota kit costs more than the whole conversion so far..
 
Craig, you are what made Britain great, please tell me you machine to aerospace spec, in a shed, on a first world war gun lathe with a 39 thou run in the bed, using a technical drawing made on the back of a fag packet. :LOL:
Give me a bell when you want the speedo, 'taint going nowhere.

My entire conversion cost somewhere around NZ$4000, including the rebuild of the transmission and torque converter, the custom cross member (made by a professional), new exhaust mid-section, the extortionate cost of compliance inspection and certification, and all the other sundry costs picked up along the way. The Dakota Digital converter was about NZ$450 all up with postage, so it represents a little over 10% of the total project cost. It was bearable, and the convenience certainly won it back points it lost in cost.

Well if that is the case, then the world is your oyster, if we can put a man on the moon, you can fit a speedo drive to your tailcone for sure.
There are drive worms available to fit your ZF output shaft, but they are rare now, and you would still have to overcome the cable drive side of things.
Interesting stuff.

I hate to break this to you, Andy, but you lot didn't put a man on the moon. It was the Americans (although some say it was all filmed on a set in the New Mexico desert). However, I do want to know more about one of Britain's great achievements. I'm presently commissioning a BMS project alongside a bunch of Indian electricians (imported for the earthquake rebuild) who are carrying out the installation work. Keeping them organised and under control is proving to be very hard work. How did the Raj manage it?
 
I am a humanist, so the "we " is a collective we, concerning all mankind 8) , we are all links in a very long chain.
What is BMS?
