[Healeys] Thread size on shift knob.

[Simon Lachlan]

The so-called “check strap nut” is 5/16 Whitworth. I dug out the paperwork from when I ordered both back in May ’05.

Many have probably read this but if not here is an interesting post on BN1 gearbox threads.

Michael is right, now that I think about it.  But I’m not sure on the door hold-opens.

Tore my generator down the other day; surprised to find that the pulley retaining nut is BSF (20TPI).

 

I believe all the fuel fittings are Whitworth (fortunately, a 13/16" socket works well on the banjo bolts).

Coarse threads...
Off topic, but there are some other coarse threads that I can think of...

The RH and LH threads in the door check assemblies.

The head studs into the block and other studs into cast iron components.

And oddly the generator end bracket uses a BSW thread for the tensioner locking bolt...

All for good reasons I suppose...:-)
