That's a great suggestion on marking it ..so you can see at a glance if
it's moved.
I use 'a little' lock-tite on them.
I have taken apart thousands of things I lock-tited..
I've never found it to be that permanent at all really.
and it is underdesigned some on the subaru.
the pulley only goes down over the crank a short way. like a quarter
inch or so ..
not that good.
On the waterboxer engine it's about and inch and an eighth or so ..it
really is down over the end of the crank,
not stuck on the end of it .

The ONLY problem I have had with my Subaru installation is this bolt
coming loose. When it does, the pulley does a number on the woodruff
key and slot in the tip of the crankshaft that aligns the pulley and
timing sprocket, and the timing sprocket (which normally justs slips
on) is nearly impossible to remove. So lesson learned. Torque the piss
out of it (...or factory recommended setting, whichever comes first),
a dab of locktite (obviously not the permanent type) and then I index
marked the bolt and pulley with a yellow paint pencil line (like they
use to mark parts at the junk yard). You can see the pulley and bolt
from the rear license plate door, and every so often I will look in to
make sure the bolt has not loosened.

Thanks,
I planned on using the higher torque value. Just did the timing belt
on my wife's 04 Impreza and the torque value was 130 ft lbs. in the
Haynes manual. I also remember reading a discussion on the torque
values and how it is listed to low in manuals. Is the lock tight,
medium strength, not needed? I figure it wouldn't hurt since I don't
plan on taking the crank pulley off for a while and definitely don't
want it coming off during operation.
Thanks for all the info,
Matt

Matt,
The earlier Subaru specification for the torque (69 to 76 ft
lbs)was far too low - the later manuals call for 120 ft lbs. I always
use 120 ft lbs and never use lock tight at that torque.
The lower torque value often resulted in loose crank pulley and
damage to the crank shaft. Be sure to use the higher torque as Leon
suggested.

Then my plan is to get a new crank pulley bolt and maybe a
little lock tight.
