Hi There,
A couple of people asked for me to post what I did to resolve the speed sensor issue off the transfer case. So please find a couple of pictures attached. I have a very talented machinist who has now machined up a fitting with a female thread that will mount to the transfer case and a male cap made out of brass that will seal off the cable drive.
I have decided to go with a GPS mounted speedo with a distance measurement included. I haven't found out about the legalities of this as yet, having not found a person willing to comment, a problem they hadn't come across before. I'm sure if I am stopped the speedo drive will be the easiest thing to explain away.
The thread is approximately 22mm x 1.5mm pitch, however when done exactly to that diameter and pitch the thread still required some "tweaking" which took a fair while.
I'll post some more pictures when the speed sensor is mounted on the transfer case.
Sensor fitted to transfer case...........that was tight!!!
Hi there,
Well the sensor and the two adapters are now fitted. I wouldn't have been possible to fit an adapter for the speedo cable flange without some significant issues and modification. The later speedo cable with the screw end could well work. There is about 0.015 thou between the sensor and the end of the gearbox shaft. The gearbox shaft is hardened and you can't get a grinder in, I tried.
I had to file off the flats of the coupling attaching to the sensor to the transfer case adapter and had to tap the nut tight with a small pin punch, didn't feel very good however options were very limited.
Couple of pix attached.
