Thread of Front Wheel Hub Cotter Pin Hole
Posted: Wed May 15, 2002 3:11 pm
by Rob & Tammy Greaves
Does anyone know the thread of the small hole on the side of the front hubs? I am trying the replace the screw that goes in the hole ... Murphy's Law ... one of the holes is buggered up enough to not allow me to do this... I have a fairly large tap and die set, however, I do not have whatever size this is.

Rob,
1/2"-26 tpi, I have the special tap. If you don't install the TC special
steel plug use an MGA type of rubber bung/seal on the inside of the hub.
Otherwise water can enter the hole and may ruin a wheel bearing.

Bob, good call on the 1/2" - 26tpi hub hole. That's BSC thread - British
Standard Cycle, one of two places I'm aware of where TABCs use BSC threads.
The entire range of diameters is 26 tpi and to my knowledge it's the only
1/2" size that uses 26 tpi. Tough tap size to find.

A Google search should turn up a few leads. I've occasionally come
accross specialist fastener vendor sites listing BSC taps aned dies, but
didn't make note of them.

Tomm, Chip et al.,
AND if I may continue this THREAD!..............! (Ahem!) The head light
mounting bolts (tubes?) are BSC 26 TPI, as are the track rod and drag link
ends; these latter of course are left-hand threaded on one end.
Now THERE'S a must-have die to challenge us! Believe me!

David,
Before you buy that expensive left hand die for the track rod/drag link
ends, you better check the thread. I believe you will find it to be 5/8"- 20
tpi left and right thread on the TA/TB/TC ( not 26 tpi ).
