Thread: Series 3 Rebuild.

My Bro has the same setup on his 2A.Works via magnets on the tailshaft and a pick up sensor.
As TJ states to calibrate you hit set it to calibrate,drive1000m and finish the calibration.You then have a Series with a very accurate speedo/odo without a waving needle AND you can run ANY tyre size/diff ratio all thats needed is a simple re-calibrate.

I found that you can actually get a sensor which screws into the original speedo cable connector on the transfer box. So there's no need for gluing magnets on the tail shaft. I'm definitely going to look into getting one (Or Two) of these..

Hey Wolfman, was that a VDO sensor? Tell us more.

Yes, from VDO. I downloaded the VDO catalogue and it had a series of sensors for their speedo range. It's just the matter of finding out which one we need for the Land Rover. (And that model of Speedo). I believe there is two , clip on (Series 3) and screw on (2/2A). And need to get the sizing etc.. Not sure whether we can get it here, but I'm sure that it can be ordered if needed.. I'm going to see one of the guys at Autobarn tomorrow, and see if he can get me some pricing, and maybe even order me one..

This is the Catalogue:

That describes the speedo end of the cable, not the transfer box end. Transfer box fitting is the same on all Series Landrovers (except Stage 1 and possibly early 80") and has a circular plate with three screws that holds the fitting on the end of the outer cable, driving by a square hole that fits the inner cable.

I would go for the magnet pickup.Chances are using the Landrover speedo drive you will still get an in-accurate speedo.Part of,if not all that "Series Needle Dance" is caused by the transfercase speedo drive.
From memory my brother first mounted the magnets on the park brake drum but lost them off-road.He then went for the more protected tailshaft.

The wavering needle on many Series Landrovers is caused by the speedo drive worm gear slipping on the output shaft - but this is easily fixed! The gear is only fixed to the shaft by being clamped between the output flange and the rear bearing. Simply tightening the nut holding the flange on will fix the problem (and prevent wear on the splines of the shaft and flange)

And the other thing that stops the speedo bounce. Is that, this speedo that TJ acquired is electronic, so if there is any play in the gearing that will cause the bounce (So to speak) the speedo will compensate for it. So the speedo will sample the signal, much like the electronic fuel gauges do. To stop the needle from bouncing around and giving inaccurate fuel level readings, speedo will do the same thing..
