took us 2 days to get ours off. in the process, we smoked one of them loaner impact wrenches <it was rendered trash by them when we got done> and split a socket too. we tried the starter trick and everything. ended up having to get a set of 6-point impact sockets, and a 24 inch breaker bar. my daddy turned while i held a prybar that was wedged in the flywheel. as for retorqueing, we just got it as tight as we possibly could, because our torgue wrench only went to 150 also. never had a problem with it in the year and a half it was on the road since. anyway, doesnt the forces from the engine and stuff tighten it up anyway?

No tightening forces in driving, woodruff key holds dampner in place. Am concerned about vibration loosening. 6 point impact sockets are the only way to go.

Have pulled four "C" dampners now (not something that has been required often) but only had one that resisted the starter trick and some persuading with the Monkey-Ward impact took care of that.

And on that subject, my wife surprised me last Christmas with a Sears 6 HP (2 hp running) 150 psi compressor that came with a set of air tools. Not sure what the 1/2" impact is supposed (claims up to 250 lb-ft) to do but at about 120 seemingly light taps per minute it doesn't seem to be doing much., the aunchient electric one tries to twist my hand and the impacts seen at least fout times as fast. Does get a bit warm after a minute.

well seeing as how I have to go to the parts store tomorrow to get the sensor that I broke off in the process........I will see if they have that loan a tool program and see what I can do I really dont feel like getting it towed to a garage.....and I like doing things myself....so an electric impact gun should do the trick you think? and what is the best way to stop the pulley? Mine seems to have come seperated as well as it turns to the left and right very easily...not a full turn more like an 8th of a turn..so that could be casuing a problem too...I dont know....had my dad stumped and hes a mechanic.....we had a large pipe and wrench....when we did finally get the thing to lock...it would not budge.....my dad was using all his weight and force and nothing!

well I have no choice but to get it to a garage now...and yes I heard of one....but I dont own a compressor so off to the garage it goes......cause I cant drive it....broke the cam sensor and the harmonic balancer itself is f****d so its a tow truck and to a garage

you try using a breaker bar w/ prybar? that worked for us

yup tried that....wouldnt budge....looks like its been on there for awhile :(

These never come off easy (wouldn't want it to) sometimes you just have to come back a few times. Bought an electric impact a long time ago because I did not have a real compressor. Claimed to be good to 250 lb-ft but probably more like 2/3 that in reality.

Have had a number of big bolts take several minutes to move the first fraction but after that they spin off nicely. Occasionally I have had to stop and let it cool off before coming back to it.

Think I paid $100 on sale 25 or 30 years ago if that is any indication, do not even know if they are made any more since prices on air tools have dropped so far.

Have seen air impacts rated up to 650 lb-ft but have not checked just how much air they need - may require a commercial compressor. PSI alone it kinda like HP, it is torque times RPM that is important and for air tools it is PSI vs SCFM. One without the other won't get you there.

This is the sort of thing where just torque won't work. Sometimes you have to hit the end of the breaker bar with a hammer to jar the bolt loose.

meh Im just gonna take it in and have it done for me....I cant be bothered....I am already going to be without my car for more than 4 days now
