Hi Ray,
I think that you will find that the worm is actually internally splined
and is secured to the steering shaft by the shaft having been swaged at
the lower end.
I have not had much luck trying to use worms with pitted bearing faces,
the box feels very rough. If you contact some of the Australian
restorers you may have some luck finding LHD worms because they are
usually replaced when cars are converted to RHD.

Subject: [Healeys] steering box rebuild
List:
I am still working on rebuilding those BN-1 BN-2 steering boxes. (
I'm Making two out of the three I have on the bench ) A real job came
up and delayed things a couple of weeks. Got the last one out of the
car and cleaned up yesterday. One box has cracks at the steering column
so that leaves two good ones. I will mike the bushings and replace and
hone as necessary. I also intend to bore the seal diameter about .090"
deeper and fit two lip seals. I did this on the idler bodies and it
puts the lip seal on a part of the shaft that shows no wear. All the
pegs look good so I'm OK there. Of the three worm gears one has very
deep wear but looks smooth, the other two show much less wear but have
tiny pitting on the bearing surface. How much will the pitting affect
things with such a slow moving bearing? What is the group knowledge on
the best repair? If I can find new worm gears I can cut and re-weld the
steering shafts. It doesn't look like the later worm gear will
fit the early box. Is there a source for the worm gear? If I just put
the best parts together I will probably have pretty good boxes but it's
not a job I want to do twice. Especially after the car is all painted
and pretty. Anyone got any ideas?? Answer on list so we can all share.
Regards
