Dunno about his electric impact, but my electric impact went at it for a long time on the rotor bolt (factory installed) till the socket got warm and the bolt just sat there giggling at it. Suppose I could go read what it says but I am guessing its rated for somewhere between 150~250 ft pounds, and im sure would have been fine to install the bolt, but the factory must use a 1" drive 300psi@200cfm to install them... Cause this impact has always gotten lug nugs off fine and they "should" be torqued to 90~100 ft pounds by spec. Also have heard the stories of the dealers that just use a impact for off and the same impact back on. Its not like its a Space Shuttle or anything, biggest thing is making sure the flywheel is on the shaft all the way aka: woodrift key not binding But as per normal.. its your ride, borrow a torque wrench if your nervious about it, go buy a cheapy Beam type only one I had access to happen to stop at 120 ft pounds so I borrowed a clicker type, but do not think I would again, but its my ride.

It took all my strength to get the rotor off and all my strength to put it back so I figure its OK. Dennis A18 The Big Red 1 [Non-text portions of this message have been removed]

I must just be missing something. Without a rotor holder wrench -- which the original poster wants to not have to buy -- what keeps everything from wiggling around on each blow from the impact wrench? I can't see how it is any better to use an impact wrench to tighten the bolt *without the rotor holder wrench in place* vs. an ordinary wrench. Can someone please explain this to me? *With* the rotor-holder wrench in place, sure. I know that it's possible to apply reasonably repeatable torque values with an impact wrench, even without a torque limiter (a.k.a. "torque stick). But without it, why would you expect things to work? That's the part I don't get. Thor

the reason this works is because of the way in which an impact works it bangs and just taps it in little increments. in otherwords it isn't just a constant steady applied force which is therefor harder to resist. whereas due to the nature of the impact it only requires a little bit of resistance in order to resist the short and sudden impacts. the definition of impact is a large amount of force applied over an incredibly short period of time ie) ball hitting bat. so the rotor is only wanting to move in little increments which are quite easy to resist with very little force. i doubt if i explained this very well but i am sure if you have seen an impact in use a couple of times my explaination might help a little. glenski a14 --- In DSN_klr650@yahoogroups.com, Thor Lancelot Simon wrote:
