I've just used my 425 lb. impact gun on max. with  blue loctite for years and everythig has been fine and a whole lot easier.

I forget what it actualy is but the gun makes it a whole lot easier taking the bolt out too, axel nuts too which I seem to end up doing quite often for one thing or another, different transmissions and such :D

I've got a 110 volt 1/2 inch gun also that I got from Harbor Freight, I think it's rated 250 lbs and the are only $49 now, I saw one the other day there.  It comes in handy especialy if you have a generator {which luckily I do} and you can take anything apart on these cars with it that's sitting in a field or a junk yard all rusted to hell and such wth a little PB Blaster or the equivelant on axel nuts it's especially nice.  I've used it also on the crank nut with the blue loctite with no problems but I usualy use the bigger air gun on it, never had anything come loose so far :wink:

According to the manual the torque spec for the crank bolt is 66 ft-lbs + an additional 90 degrees of turn.  Yes, it is a big number.

As I have a wobble in my PS pulley I am going to take all the pulleys off and see what is the problem.  For certain I will replace my crank bolt with the updated one.   In fact, last week I bought this at the VW dealer for around $4.00--it was a surprise to me that the dealer in Tucson actually had it in stock.   I am also planning on replacing the crank toothed belt pulley.  Of course, once I take it off if the crank nose is damaged seriously it will be time for Plan B.

The question I have is what method or methods do people use to lock the crank so that they can remove the bolt as well as to reinstall the bolt?   Is there a special tool that can be purchased or one that people fabricate?

Thanks for any suggestions or advice as I am putting off doing this but know it needs to be done before the gear skips a tooth on the timing belt.

Here is the one that I built.  It's just a 4' piece of angle iron that has the matching bolt pattern to the crank sprocket.  Thanks to Libbybapa for the idea on this one.
