[Vwdiesel] crazy cam gear removal

[Erik Lane]

it sounds like you're doing everything i've ever done.
if there's another good trick out there that someone
comes up with i'd love to hear it!!

as far as advice - i'd just say keep working on it.
don't give up - sometimes they'll stick at first but
then eventually give. but be careful about putting too
much pressure or stress on that gear! unless you don't
mind replacing it, which i guess you might end up
getting stuck with. i'd just keep penetrating oil on
it and let it sit along with putting pressure on it
with the puller and tapping it lightly as well as the
heat. i think all those things are good. just
alternate from one to the other (or multiple at once -
even better) and give it time to sit with the oil and
puller just sitting on it with pressure. maybe it will
move a hair? as long as it's not a big hurry then you
should be able to get it off eventually.

oh yeah, make sure that your puller is really pulling
straight. it can make a big difference, and sometimes
they really seem to want to pull crooked in spite of
everything! tho you having drilled it a bit should
keep at least that part pretty good.

good luck!
