[Healeys] [Fwd: Re: steering box rebuild]

I had this pitting problem with my 3000 steering box worm ( a second
hand one I got to convert my box to RHD). You say BN1 and 2 boxes, isn't
the worm on the later BN1 and 2 boxes rivetted onto the splined steering
shaft like the early 3000 boxes? I removed the worm, re machined the
pitted area, re hardened and refitted. Had to heat the end of the shaft
and worm red hot to get the riveting to close down to get the worm off.
I then shimmed the bearings to allow for the reduced length between the
bearings from the machining. All the new worms I have seen aren't made
with a high spot in the middle like the originals, so can have a tight
spot in them over their range. I would try to fix yours. I have a left
hand drive worm that came out of my car that is in good condition, but
it has been red hot on the end and would need re hardening.
Cheers

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.
