Gear lever jam nut 506157

[ianc]

At the NEC Show, Mike Walter told me that he was missing this nut and had no idea how to obtain one as it is an odd size: 7/16" AF, 32 TPI and very slim.

Moss don't list it, but Revington has it superseded by NP505064 - which is available and less than a quid!

Thanks, Ian -- this is a tricky little bit. And for those who missed a similar discussion a few months ago:

Is this car a TR 2/3? If so.....

109047 is the lock nut for TR 2/3 gear lever They are made in England and Moss stock them.

Correct 7/16. X 32 ME thread..

I prototyped them for the maker.

PS NP 505064 I guess is a 5/15 Unc to me that fits tr4 onwards.

Mike Walter told me that he was looking for a nut to lock his knob (well ... the car's) onto the gear lever.

Looking at the TR2/3 WSM, I cannot see a nut up there, but 109047 would appear to be present to lock the gear lever to the ball end (i.e. at the bottom of the lever). It's 44 years since I owned a TR2, so I cannot remember how the knob (which was alloy in my case) was locked to the gear lever.

On the TR4, the ball end and gear lever are a single item, but there's a jam nut (506157) to secure the knob to the gear lever. I thought this was what Mike needed, and Revington lists NP505064 for that duty.

I am sure that my old friend Peter will correct me if I have made a mistake.
