I'm thinking my crank hub woodruff key is toast -
can I use a parts house kit to remove and inpect ?

Symptoms:
I went to check the timing on my car and balancer
was showing 60 deg advanced !!!

I think the problem was due to an incorrectly installed A/C compressor -
the a/c bracket was rubbing against the balancer.

Finally removed the balancer last night - no signs of failure,
but numerous bolts were loose (including the crank hub nut !)

Checked for chain stretch/TDC/cam timing -
Hand cranked using a wood dowel in spark plug hole
to "reckon" TDC - Top of pistion travel is at Cam Timing Mark,
so I don't think there is chain stretch /slippage.
(Chain is almost brand new).

At this point, I think the woodruff key on the crank has been sheared,
and the "hub" has rotated. (the flange looking piece of metal the balancer attaches to).

any input appreciated....
