When mine fell out a while back, it was while backing into my parking space at work. Noticed the PS was gone, but no !, and good pressure. At lunch I got maybe 10 parking spaces before the ! came on for pressure and voltage. So maybe it can fail a little "slowly" and you really did have some pressure. Good luck.

Should I use Loctite blue or red on this crankshaft pulley bolt?

Blue, if you use red you will have to apply heat to remove it. I would also torque it to the proper value with a torque wrench rather then an air gun.

I laugh everytime I see that picture, looks like something our group would have done when I was in the service.

never use red imho.. but make sure this thing is torqued down exactly to what it needs to be.. if all else fails maybe its even better to get a new one.

with 912 engines we replace the gland nut every time you do an engine rebuild or a clutch change. they are 40 bucks ea. but better to be safe than sorry (and they are notorious for backing off if reused)

amen!! never use an air gun on anything with an engine. use a big *** breaker bar if you have to on the torque wrench to get the leverage you need.

This picture is correct procedure.
It is safe, provides enough force and gives good control.

If your gauge is reading correctly (and I assume that it is) you're fine. Check the oil for shavings to be sure - but my car and other track cars are regularly down in the low 2's at the end of long hot track sessions.

There's no reason you can't get the crank bolt off with a big breaker bar (like above) and on with a regular 1/2" drive torque wrench.

Who needs air tools? I do all my wrenching with hand tools and have never had a problem and frankly, air hoses and compressors and crap are (1) expensive and (2) just more stuff to get in the way.

I have put several of these on using a big *** breaker bar/torque wrench combo. Have yet to use an impact when removing/installing the main crank bolt.........

I would think Airgunning it would give you the 250 ft/lbs needed to torque the sucker on there. Why not use air?

Becuase an impluse is different from a sustained force. That, and my impact does not fit in there........

I've used my impact and loctite blue on my 928 and it has NEVER backed out on me. Either it's luck or the loctite is doing it's job. The pulley hasn't been removed for about 2 years now and is trouble free on that car.

Go down to OSH or someplace similar and search through ttheir little hardware bins. I match a rectangular shaft "key" to my damaged one then used a bench grinder to give it the proper shape.
It has been in the crankshaft for 75,000 miles with no problems . Even had it out a couple of times doing belts and rollers and a waterpump.
