Hydraulic pump rebuild - Day 9
>Bugger. Now I have a sheared-off driver to drill and extract from a

I feel your pain. I snapped off a no-name brand 4mm trying to >remove< one
of the caps. I tried everything I could think of and could not get it out.
Let me know if you find a way to drill it.
The best bits I could find had no effect.
So I never did replace that O-ring. But it wasn't leaking either.
Your problem sounds more serious though because it still needs to be
tightened. I don't remember how much more than 5 lbs though.
If you can't get the broken hex out maybe you could either remove the
capscrew, or rotate it a bit tighter, with a centerpunch and hammer?
