Did a search already and found out you could remove the crank pulley with 150 psi but I was wondering about the size of the tank. Will a 15 gallon tank be enough to take the crank pulley off?

Someone must know.
HELP

 

suggest you IM the people who did it.

 

It should be, but keep in mind that the type of gun you use is just as important as the compressor (since you're only using very short bursts, large capacity isn't really critical). Our old 1/2" gun (I don't remember the specs or brand right now) wouldn't budge a crank pulley bolt, but when we switched to a much larger 3/4" Craftsman gun, they're off in a matter of seconds.

 

Thanks Padawan.
You happen to answer my next question about the impact gun.

 

Most impact guns work best @ 90psi. It's all in the gun you get, you dont need anymore than 90 if you have a good gun. I've done it plenty of times with my 1/2".

 

I had to crank my brother's gun up to 150 and let it pound on the bolt for a little bit before it came off. It was just a matter of patience for me since we didnt have one of those rambo impact-guns

 

i just did one and if u cant get it with just the gun u will need to heat it..
i was told red hot but i dont have torches but i have propane and jus theat it for like 5 min and try it... worked for me

 

yup, red-wrenching does wonders to locked nuts and bolts.

Very true, and most people set the psi @ the compressor regulator to 90psi. What some people forget is that usually there is a hose between the gun and compressor, so depending on the length of the hose there may not be 90 psi at the other end. I have a 50 ft hose so i bump mine up to like 115-125 psi @ the compressor and i have no problems taking anything off. 1/2 Husky 500 ft lb impact wrench with a 30 gallon 150 psi max compressor.

 

ingersol 1/2inch TNT impact gun. made out of titanium with 650 lbs of nut bustin torque. works really good.

 

Any 3/4" gun from harbor freight will do the trick for less than 80$.

If you don't use the guns that often, a cheap one will be fine... (why waste money on a professional

My 3/4" harbor freight gun with 90 psi from a small IR portable 2HP compressor has removed several crank pulleys VERY easily.

I'm looking to get the same impact gun as BuddhaSiR. Look excellent.
Thanks for all your feed back.

$80 for a 3/4 impact? I paid $280 for my IR261 and thought that was a good deal.

Yup I have a ton of tools from harborfreight, even a car lift... not great quality, but does the Job fine, and nothing more is NEEDED for DIYer's ... I have have the Impact gun for 2 years now and it's still perfect.

I believe the one I have is:
http://www.harborfreight.com/c...32871

But I thought mine was more powerful... Something like 600ft/lbs max.

Otherwise I saw this one 1/2" drive which should also be fine:

two years!! I'm impressed. For something i have to use everyday, i need tools that are gonna last me a while.

 

if you have the crank pulley holding tool, you don't even need an impact gun.

 

i use some harbor freight tools too, as is my impact wrench. but you always get what you pay for...
get one thats more than 250ft/lb's though

Like I said, DIYER's do not use their stuff EVERY DAY all day long. For those applications, an Ingersoll Rand Pro series is definitely appropriate.
I use the gun on weekends once in a while, it's still fine. I use another cheap 1/2" gun for smaller bolts, and the 3/4 for heavier duty...

People always talk of spending big money on tools that they really don't need... I have purchased a lot of tools in the past few years, much of them from harborfreight and am still very satisfied.

With regards to what higher quality (Snapon, husky, craftsman, IR, facom...) tools you should get, here's my list:

- Air Compressor
- 12 sockets
- flat wrenches
- Allen/torx impact sockets
- torque wrenches
- electric tools
- floor Jack
- mig/auto darkening mask

Stuff you can go cheap on (I use harbor freight for cheap stuff):

- 2nd/3rd set of flat wrenches (i have 4 sets to leave around 2 is garage, 2 in basement)
- 3/4 inch impact (OR get 1 high power 1/2" instead of 2 cheap ones)
- 1/2 inch impact
- 1/2 impact 6 point sockets - deep and regular (Also have a few sets) - as long as you use the right size (ie nice tight fit) you wont break them easily...

 

Home-made pulley holding tool - 1/4" x 2" bar 18" long. Drill 2 holes to match up with the pulley, skip one hole on the pulley so you have more leverage.

2 foot breaker bar w/impact socket. Don't use an extension.

One foot on breaker bar, hold onto bumper. Pop that sucker off.

you mean this thing:http://www.thetoolwarehouse.net/shop/SP-60100.html

sure cost a hellva lot less then the getting a impact gun + the cost of a compresser. I've done alot of timing belts on hondas and acuras, I have yet used a impact gun. all it takes is a breaker bar, 3 ft cheater bar, and good ol' fashion MUSCLE!!!

 

remember
heat is ur friend...

 

definatly use some muscle. chances are if your bolt was like mine the impact gun isnt gonna do ****, i broke the pully bolt in my crank on my old motor. got it out tho so its cool. im with the guy and the 3ft pry bar. mine was 5ft long and my dad stood on it lol come out like a champ just have fun keeping the pully from spinnin on ya, and buy craftsmen tools. i snapped SOOOO MANY 17mm sockets. and broke the mech in a wrench. spend the cash on the impact socket
