Does anyone know the spanner size for the inhibitor switch lock nut. Just to ease the pain of trying to loosen something I cannot see without knowing the spanner to use.

Hello Barry,
The locknut is 11/16th. One of those little mirrors on a stick is useful down there to see what’s what.
Good luck
Steve

Re: Lock nut dimension inhibitor switch
Thank you Steve. I was worried that it would not pass the German MOT test without the reversing light working, but I took it there and the tester showed little interest in failing such a lovely car and passed it with no fuss at all!!
So I will leave the Gynaecology operation for a later time.

Re: Lock nut dimension inhibitor switch
I have a need to replace the inhibitor switch on my V8 BW35 gearbox, but it is the most awkward job with the gearbox fitted. I have temporarily by passed the switch to allow me to continue with my restoration (checking the electrics). Reversing light and starter circuit now on switches.
Any suggestions on how it can be done without removing the gearbox?

Re: Lock nut dimension inhibitor switch
It is perfectly possible to replace the switch with the gearbox in situ, just a bit fiddly. When I did mine I found that partially removing the heat shield above the exhaust gave a little bit more room for manoeuvre, and using a mirror was helpful.
Good luck

Re: Lock nut dimension inhibitor switch
Thanks Steve for your info.
I have just removed the heat shield this morning but the only 11/16" A/F spanner is have is too long so I am in the process of making up something that I hope will do the job. (I'll let you know)
Not sure that the switch is U/S but removing the connections and crossing them allowed me to turn the engine over on the button and the reversing light worked too, so hopefully it is the switch and not something within the gearbox. This is the last electrical item to resolve as all the others are woking fine.

Re: Lock nut dimension inhibitor switch
The switch needs to be correctly adjusted. The workshop manual covers this in some detail - if you don’t have access to this let me know and I’ll post the details. With my car the issue was that it would start in any gear, and that the reversing light would be on in all forward gears!! I replaced the switch, but in hindsight it was probably just out of adjustment.

Steve

Re: Lock nut dimension inhibitor switch
Steve,
Just an update. The only problem I have with the inhibitor switch is the reversing light not working, as it is totally disconnected. Some clever mechanic, instead of messing with the switch, got over the safety aspect by wiring the starter solenoid through the brake light switch, so it will only start when the brake is applied. Not a bad idea!
