Playback tach magnet question
 

I have a 2 channel Autometer playback tach that I use to record every pass I make to make sure the clutch tuning is in line. I just changed a rear gear and when running in the new gear this past weekend I had the magnets come off in the driveway. It appears that the JB weld de-bonded from the U-joint cap. Is there a better or an improved method to attach the two magnets to the driveshaft U-joint caps besides the JB weld that Autometer suggests?
Thanks
Dave

Oopps I just realized I put this in the wrong section sorry..

Collar from Williams

Autometer also has collars a couple differant rear end sizes and a universal one you can machine.

Hi,

Sometimes there are clearance issues with the collar around the companion flange.

As an alternative solution, you can drill the companion flange and insert the magnets with a little epoxy.
