I'm not sure of the exact location of these pins, and my

suggestion may not

work if there is not enough surface for a base for the lever

(enough to

locate the head of a pair of side cutting pliers) , but we used to

get

hardened pins out of blind holes in injection molds by using a

pair of side

cutters (to get a "bite" on the pin) and leveraging it against a

block of

hardwood or brass under the jaws (to protect the mating surface of

the

mold).

Working the pin out of the hole this way always worked, as long as

you

weren't going to reuse the pin.

Not much place to get a bite as the pins are flush. Grinding the
inside
of the diffuser until the end of the pins appear may be the best
way.

How about a small drill bit to drill througn the housing to the
 other side ? Then back drill a larger hole to allow the pin to
pass through ? Virg

Sorry guys, but neither of these methods will work.
It will be hard to drill through the stainless steel sleeve. Even if you
do, than what? You can not line up a drill bit to back drill since you are
inside the sleeve and it's is too narrow for that.
Now! This foreigner with funny name has done it four times without
problems: Get a drill bit smaller than the OD of the pin and start shaving
the inside of the pin. You may have to go on the second pass with next size
up, but still smaller than the OD of the pin. Eventually the walls of the
pin are so thin and weak that it will spin  and come out.
