[Healeys] Broken Screw

[John Spaur]

The location of the broken screw makes it very hard to access with a drill
unless the engine is removed.

There are a few options, none guaranteed.

 

1. Drill a hole in the broken screw and use a screw extractor. Apply as much
heat as you can.

2. Drill the correct size hole in the broken bolt for a tap and rethread the
hole. Works well if you can drill very close to the centre but this is
easier said than done when drilling by hand.

 

Good luck.... Harold

Mike - if anyone in your area does EDM electronic discharge/disintegration
work, that might be the way to get it out without damaging anything in the
process.

Went to install the rebuilt horns on my BN2 last night and could only screw
one on the cross member of the frame.  The other mounting hole were a
problem.  Somewhere, sometime in the past whoever removed the horns snapped
one of the screws off flush with the frame.  Best way to get this out?  Must
have been corroded in place to snap off like that.
