[Healeys] Another thread question

[m.g.sharp at sympatico.ca]

Mike, it is a longshot, but could the fitting have been over-tightened in the past and the threads have pulled?  That is not uncommon on smaller bolts, and I had that issue with the rear axle of the TC once.  I could not get a new nut on the right side and when I looked carefully the tpi varied across the threaded length of the axle.  In that case it was a LH thread, and I think some ham-fisted in the mechanic, in trying to “undo” it used excessive force.  Of course he was turning it the wrong way and he simply stretched the threads.  I had a devil of a time fixing that!

 

Cheers, Mirek

The inhibitor switch which is used in overdrive gearboxes has a thread that I cannot identify.

Measuring the outside diameter of the thread I get 0.618" ... probably 5/8" (0.625)

The TPI is 13 ... definitely not 12 or 14.

Can't find it in my limited resources ... 

Anyone able to identify this thread for me?
