Reverse switch location

Question:  I am finally reinstalling my back up switch after years of it sitting in the engine bay.  The ZF cover is not threaded and the stock switch (which does work when the lights are on and depressed sufficiently) threads are smaller than the hole.  On the early cars, was there a nut put inside the case to secure the switch along with a nut on the outside to lock it in place?  Any insight would be appreciated.  thanks

As I recall there are 2 nuts to allow for depth adjustment. If the switch is too far in it can prevent the trans from going into reverse.

Is the nut on the inside bonded to the case somehow?  Not sure I see how to adjust it once installed if it is a loose nut?

Seeing these pictures reminds me there were spacers, no nut on the outside. The nut was not attached on the inside.

A previous owner has managed to destroy the OEM mount for the back up switch. The selector housing cover was built with female threads that accepted the male threads on the back up switch. The OEM design had adjusting nuts inside and outside the housing. You might be able to securely mount the switch with nuts and washers despite some idiot having drilled out the OEM threads

Good luck

Here's a pic of the new style of reverse switch. Notice the Weatherpak connector. This is the switch you now get from the Vendors. I got this one from Wilkinson.

David,

does that replacement switch you just pictured above retain the OEM threads?

Larry

Yes.

thanks guys
