Stanley's water pump needed to come off, something (probably the oring in where
the impeller shaft goes into the engine) was causing leaking out of the weep hole.

We busted one of the bolts that holds the water pump on, flush with the case.
Then we broke off an ez-out in the stump. We tried hard to drill out the ez-out
with some nice drill bits I have, it seemed like it would take days.

He went home in my truck, is coming back in the morning. He may try to spot
weld a nut on the stub, but there's not much stub and we have advice that
the weld joint on the bit of hardened ez-out will be poor at best.

If that fails, we plan to try to drill at the edge of the bolt, case be damd, put
liquid wrench down in there and try to bump the stub loose with a punch,
and fix the damage with a helicoil.

If we mess up the case (its not looking good for us so far  Cheesy ) Mitch has
volunteered to let Stanley bring the bike to his house... that part of
the case is just a little cover. I don't want to take that cover off because
I'm sure engine parts would spill out, but Mitch can do it  cooldude ...

I guess it would be a bad idea to run Stanley's bike with only one bolt
holding the water pump  Roll Eyes ...

I saw the pic of the broken bolt. My experience with easy outs hasn’t been easy. My plan would have been, centerpunch the broken bolt and start with a small drill bit and move to progressively larger bits until not much is left then try an easy out. If that fails then make sure you have all the bolt drilled out that is safe the get out the taps and retap the hole. It worked on my Wing frame.

Yeah, it was a drag when the bolt broke. And a REAL drag when we filled
the hole we drilled in the stub with part of an ez-out...

We didn't centerpunch a pilot dent and the hole we drilled in the stub
was off center which led us to try a too small ez-out in a too small hole
in a too stuck stub...

If I feel any resistance , I have blunt punches. Tapping ot hitting the bolt  head and WD most times will work. If resistance is felt , soak and turn bolt in. Try again.

A good drill press or mill with milling tool will be able to remove it.  If you have a tig welder you can heat up the bolt, aluminum will expand faster than the steel bolt as I am sure you already know. Heat and let cool a few times. Allow metal to cool naturally. Do not spray anything on it while it is hot.

Also slow cooling will change the properties of the easy out.

I've had luck in the past by drilling very small holes (#40 - #45 drill) into the stud as close to the easyout as possible - even if its a little ways into the surrounding metal.  Put a succession of holes about half way around the easyout about 1/8" deep, then get a punch and knock the easyout towards the holes you drilled. Then knock it back where it was and repeat. It usually lets you wiggle the easyout enough to un-wedge it and get it out.  Good luck.

We worked on it a bunch today... well... mostly my local welding guy worked on it.
Plus instead of sunny and nice it was drizzly and chilly.

We didn't get the stub out. Stanley's going to bring his bike to Mitch's in a few
days...

We called it a day around 3:00, ate some hotdogs at the local eatery, and I
hauled Stanley back to Athens...

Time to remove the cover to do the repair or replace cover. You can purchase a used cover for about $40.00.
If cover is not damaged bolt and easy out can still be removed with a milling cutter or diamond tip.
I have drilled hardened transmission shafts with a good concrete drill bit that a good standard drill bit will not touch. Cutting/cooling liquid required.

The welder guy said the same thing about good concrete drill bits.

I have these "Roll Forged High Speed Steel. Superior to carbon steels." bits
that I think of as my "good bits". I worked on the stub/ez-out-chunk for a long
time with the drill turning real slow and lube on there, but only made a little
dent that I could see with my magnifying glass.  The welder guy drilled on it
with his bits too in preparation for his third try to get a nut welded to the
stub...

I've formed some opinions about ez-outs during this episode... center punch a
a good place to start drilling the stub, drill numerous holes with successively
bigger bits until you get a good sized hole, get as big an ez-out as you can
stuck into the hole, and turn the ez-out with a wrench or hand-power somehow.
A powerful drill will make something give, but maybe not what you want...
ez-outs are hard and brittle...

By the time you drill a big enough hole for a large easy out, act like you never ever heard of an easy out and drill just shy of the threads and than pick the threads out or tap if possible. Reverse drill bits can be helpful but are hard to come by.

EZ out is an oxymoron. If it is seized, the EZ out seldon works.

There are those with the skills and patience to use such tools.   I would not be one of them.   Can't tell you how many EZ outs I've broken inside of that offset/not centered drilled pilot hole in a stuck bolt. 

Hey, I'm still looking for my talents in life.   So goes the search.  Wink

Off center hole does not allow circular torque, it causes an elliptical torque. Not good in this case.
