what size compressor is required to break harmonic balancer bolts loose using this tool? Can you give SCFM / gallonage / psi?

I don't have a harmonic balancer, but I used this on the crank bolt holding my miata's harmonic damper in place. I previously torqued it to > 100ft lbs and used red loctite. It came loose after about 10 seconds of pulling the trigger. Barely used any of the air in my smallish sized compressor.

This tool is intended to work off no more than a nominal 90 psi, but given frictional losses in the airhose, you can safely set your compressor to 100 or 110 psi without doing damage. Harmonic balancer bolts may come in various sizes, so an answer is difficult - but I can tell you that I've loosened overtightened wheel nuts (probably run up to 100 lb-ft of torque), though only after boosting compressor output to 100 psi. As for SCFM, keep in mind that such tools are heavy users of compressed air, so continuous running will cause rapid cycling of the compressor, unless you have a commercial/industrial size unit. I use it with a 4 cubic foot receiver and find that adequate for cyclic use - but would expect the compressor to run continuously if the trigger is held down. I'm not sure I believe the assertions that the unit develops 500 lb-ft in the reverse mode, except maybe "instantaneously" since 500 lb-ft would probably shatter a wrist! Additionally, the unit may be stymied by totally rusted bolts, even of moderate size.

I took off a crankshaft pulley bolt (using this impact wrench) with a 20 gallon compressor that produces 5.3 CFM at 90 psi. It worked great; ripped it right off, no fuss.

depends on the balancer and how tight it is. I'd run the compressor at what ever tank pressure will consistently read 90psi with the tool running, probably 100 psi or more. I wouldn't go lower than 4.5-5 CFM, but it'll want more like 10-15 cfm under full load. Compressor ratings are for constant usage, your usage is momentary for an impact wrench. I have a 33gal compressor that'll do about 4.9 cfm and that's adequate. Next compressor is going to be a 60-80 gal though, but not specifically for this tool.

I believe you could safely use the 20 amp rated sq D pressure switches, I am currently using one on 2 different compressors 1 is a 30 amp 240 vac 20 cfm unit the other is a 25 amp 240 vac 14 cfm unit. I think the worst that would happen you will burn the points out sooner (the origonials went 20 years and 11 years respectively).

I don't know the specific requirements for the compressor. I use my nailer with a small 6 gallon Porter-Cable portable air compressor and it works great. This is an excellent tool that has given me good service. I hope this helps.

I'm not sure I would buy a compressor for one job: they're not cheap. But if it's a big shed, and you have other future stuff in mind, OK. I would think you need a compressor that will do 2-3 scfm at 90 psi. The gun needs 80 psi or so but doesn't use much air in normal use. Depending on compressor type (oil or oil-free) you will probably need a small filter as well, not expensive. And hose fittings. All on Amazon. I spray wood finishes as well, and have a Makita 4.5 cfm, highly recommended, but more than you need.

Jim - The universal pressure switch will work on any compressor whose tank has a two wire motor connection, male 1/4 pipe thread tank fitting, and unloader connection to the compressor. It starts the compressor at around 90 psi. and shuts off at about 125 - 130 psi. Hope this helps. :)

I am not sure how much psi as my compressor is too small for it. If you have the air you could use any surface grit or polish

Not sure if it will work with that particular compressor. You could probably check it out locally at most any bicycle shop.

My small (6 gallon)compressor has plenty of power. I set the pressure to between 80 and 100lb. I operate everything from this tool to brad nailers to my big framing hammer...I shoot a lot of nails and brads...framing, laying sub-flooring, laying hardwood floor and trim work/base board etc..

Get quick release adapter...Male on compressor end. Ask any hardware store...Good luck.

I would think a 3 gallon compressor would work well. I use mine to blow off the mower deck and air filters on various types.

I used a Kobalt 10 gallon compressor with a tank pressure of 155 lbs and set the line pressure from 85 to 92 lbs. and it worked just great. Compressor was not overworked, and nails were driven through various dimensions of lumber.

I had no trouble with this tool on my Bostitch 6 Gal 3.8CFM @ 90 PSI compressor. I did need to use 110PSI, and it could drain the tank in a min, but the tool worked quite well.

It will work, but you will have to wait so compressor recovers. Better off with hammer and chisel

I believe its 120 psi. There are also some excellent videos on this product on You Tube. One is all about this compressor. I think you might get all of your questions answered from it.

It did for me. I had the compressor to 90 psi and it worked fine. It did not have the power to remove the brake caliper bolts that had been on the vehicle for 110k miles though. Had to use a breaker bar and a hammer to break them free.

You haven't provided what your small household compressor's CFM is. You need to have a compressor that can support the at load cfm value for the impact gun. It easily takes the toughest lug nuts off. Good Luck.

Yes you need an air compressor with a minimum of 16 cfm to run this tool. I would however recommend even more cfm than that as this tool is a bit of an air hog.
