sufficient air compressors
 

so im disassembling my 13b and have got to the notorious front eccentric shaft bolt and the flywheel nut. i found a old small air compressor laying around and was wondering if it would be good enough to power this thing [ 1/2 in. Professional Air Impact Wrench ] to take off the nut and bolt mentioned.

The compressor i have is a craftsman with 1hp, 7-1/2 gal. tank that puts out 5.0 scfm @ 40psi and 3.3 scfm @90psi. Im debating whether or not to get that impact gun to help me because i dont know if that compressor is good enough lol. Cause a impact gun is only good with the right compressor, correct? What kind of air compressor should i be looking at to power good enough tools to take out the front eccentric shaft bolt and flywheel nut?

Most any compressor can run most any impact gun, but a cheap compressor may only be enough to run the gun for a couple seconds. Also it is probably oil-less so it only has a 30-40% duty cycle which will require frequest breaks for it to rest. You will probably eventually get the flywheel nut off, but with that small of a compressor it may be a cycle or two of letting the tank fill, compressor rest, and impact use it all up again.

Always buy an oiled compressor if you will be using it for anything serious, beyond that size and CFM ratings will be based on what you are doing with it and how much down time you want to be forced to take while using high volumes of air.

If you are just buying the compressor to inflate tires, run an impact long enough to zip off bolts, use a blow gun, use a nailer/stapler or use an tiny air brush, then any old compressor will do the job.

But if you intend to be able to run things like die grinders, sanders and media blasters, you will need at least 10 CFM continuously. Which means a real 3 - 5 HP compressor.

As for the front and rear nuts, the most important thing about that is to heat them to release the Loctite. After that, a decently sized air gun even on a small compressor should have little trouble removing them.

k thanks guys. i ended up getting the nuts off with just 1 extra set of hands without air tools haha. might still get that impact gun to make things easier. i actually have the compressor already its been sitting in the garage.

I just use....."MR PERSUADER"....duh,dadada!..42 inch long ,3/4 inch headed Breaker bar!

I just got this thing about air tools..Nice to use sometimes But I hate the damn hose.
I'm a ratchet and wrench Old School type of guy..so If I ain't sweatin..It ain't work!

yeah haha i used a 4 foot cheater bar with a 1/2in breaker and rb's flywheel bar socket.
