For the people who work on their vehicles, impact wrenches…

[morfiend]

I'm guessing you've tried a few drops of acetone based finger nail polish remove mixed with a few drops of automatic transmission fluid an hour or more before trying to remove the bolts?
Only asking because you didn't mention it and it's amazing stuff.
Also sounds like those bolts were set with some version of lock-tight requiring heat as suggested above if the lub doesn't do the trick.

Years ago when I liked to tear apart engine the ATF and acetone was a go to. We’d use a hot plate full of ATF to take apart close fit parts and even some dry ice to shrink stuff to make it easier to take apart.

But ya if you heat bolts or nuts you should get replacements as you’ll mess the tempering up.

Original poster needs 120psi minimum to use air.   
The electric ones are good and strong but bulky……..and may create sparks.   

If you do use air, a single restriction can make 150psi feel like 15 psi if you are requesting high volume.

Not according to its manual. 90 lbs pressure max. I tried it there with the same disappointing results.  No line restrictions. Picked up a cheaper corded one, it is bulkier for sure.
Going to keep breaker bar and long pipe in reach.

I have a large 220 volt compressor, but it red lines at 90 or 100 according to the gauge. I finally realized that impact wrench I use wants 120. I'm guessing get different gauges?

Safety valve might be set to 100lbs so you might want to check that also.

Safety valve no issue here as it’s been fuzemaned to keep it running.
I don't let it run and walk away.  It’s an old one Dad had his crew make with a Square D valve.
A bit of a perk being head of maintenance at Health Research.

Sorry fuse I was talking to BJ as to why his compressor won’t go up to 120lbs. You can change the gauges but then the safety pops before you can reach the desired pressure. Then there’s volume as in how large the tank is,you don’t want the compressor running the whole time.

All very important. Include condition of tank.

No need to be sorry morphiend,  . , I cogitated it was to him but added my two cents as I had spares.
I picked up 5 pennies that day.!I had lots of common sense ( common cents… ) that day and could spare some.


Good thing no rule about bad ‘humour’.

We don’t have Pennie’s anymore so I can’t add my 2 cents…

[fuzeman]

I’ll bet you two cents you do have common sense though!!

I’ll send you a penny or two to wager.

Some of us at the dealership level use 150psi. 
When I take my 30 year old mac to a Toyota Land Cruiser with stuck lugs, it quickly either gets the lugs off or snaps the stud within 3 seconds.   

Also noticing very few motor/belt/compressor and instead see only the super high rpm roaring pumps and very low flow rates and lower pressure.   
I’m getting back to using air at home so I’m shopping motors, tanks, and compressor heads to build a nice air system here that can indefinitely run a d/a sander.   
I’m using multiple tanks with the second at the other end of the system.   

[Shuffler]

Yup.... pressure with volume. That's the ticket.

I got a corded one at Harbour Freight on sale for $40. It didn't blink at the six 15 mm , trailer hitch mounting plate bolts I removed, well, it removed.
