Hi folks

This has probably been asked before but so accept my apologies if so.

How do I fix the two magnets to my prop shaft which work with the speedo sensor?

For info, I'm using ETB instruments supplied via Luego.

Cheers in advance

Ive just done this very job. Ive fitted magnets to the rear diff flange rather than the prop (my diff is rigid mounted therefore will see less movement seeing as the sensor has to be only 1mm away!!).

Cleaned the fleange up to bright steel - absolutely no rust.
Mixed up small amount of Araldite precision. Put a blob on the flange.
Put magnet on the adhesive with the pip down over - magnet pulls itself through the glue onto the steel.
built up the adhesive aroung the magnet.
Left it overnight to go off a bit.

Rotated prop throu 180deg and repeated process with second magnet.


Make sure the sensor bracket is well secure and has no flex. Ive made a kind of bridge over the lower trans tunnel bars so it will be fixed at both sides. Sensor will then be vertical under the diff flange and adjusted to be 1mm away from both magnets. Ive heard too many stories where the brackets are flimsy, come into contact with magnets and do some damage.


If you go on the ETB website there are some downloads for this. I got above details from DD2 installation manual.
