Re: Impact wrench size advice
First thing I would do is spray the offending bolt with penetrating solution (Kroil, wd40, liquid wrench or 50/50 mix of ATF and acetone)..bang at it a little to get the penetrant into it and help break free the rust.. ...repeat over the course of a few days..after a few applications, hit it with some heat and try it with a breaker bar.....if it is a 3/4 inch bolt...what size is the head on it?.......I think if your compressor gets up to 150PSI ...and a lot of 120V units do that....it should drive the impact gun sufficiently to break the bolt free....is it a bolt that is screwed directly into a threaded piece...or does the bolt extend through the piece with a nut on the other end?
If it protrudes all the way, oil up the extended piece that goes past the nut to ease the rest of the unscrewing
If you are going to reuse them throw them in some engine oil, even used oil, while you are doing your other work and coat them with some anti seize compound before reassembly so they come off easier the next time...good luck....let us know how it goes
