Can't get this ****** off. Using an impact and it won't budge. I don't think it's the compressor or gun cuz I've taken out a few others already with the same gun and compressor. Already tried spraying and letting it soak with PB blaster but no go. Don't really want to heat up in that area...

EDIT: Well the motor is already out and just sitting here so a breaker bar or anything like that probably wouldn't help much haha.

Hum. Probably should have mentioned this but I didn't think it matter till now. The block is seized and I just tried turning the crank with a ratchet and it only goes like a little under half a turn either way. Guess I'm fucked? lol

What kind of gun and compressor are you using?

Compressor is a Campbell Hausefeld (125psi) and not sure on the gun, dad got it from his work (he does all kinds of machine work). I mean, I'm pretty sure its not either of those as I done tons of others without a problem.

 

i used the heat method. burn that sucker up!

It may be a particularly stubborn bolt, but it really seems as if the gun simply isn't powerful enough, or it isn't getting enough air.

Ours is a Craftsman 3/4" impact gun (I believe 700+ ft. lb. of torque) and 33 gallon 150 psi max compressor, and has never failed to remove a crank pulley bolt.

 

I just did mine...

I used a breaker bar, 4' pipe, 1/2 socket and extension... propped a jackstand to support the pivot... and slowy leaned on pipe.

I thought I was going to break something... fortunately it was the bolt breaking loose.

Prior to this I had tried the impact gun, and gone through three 3/8's extentions.

How much CFM does that put out? You should never run the impact on more than 90 psi (unless you want to damage your tools), but if the compressor doesn't pump out enough air, it's not going to budge that bolt.

My dad's smaller compressor wouldn't loosen my crank pulley bolt. However my 30-gal. upright compressor pumping out 6.4 CFM @ 90 psi and an Ingersoll-Rand 600 lb-ft in reverse impact makes quick work of CV axle nuts and crank pulley bolts.

hum says

SCFM
6.4 @ 40 psi
5.1 @ 90 psi

 

okay, and how much does your gun consume? Mine develops about 600 lb-ft in reverse, using 4.8 CFM @ 90 psi. That's how I know my compressor is plenty big enough.

When shopping for compressors and impact wrenches, you always have to pay attention to CFM at a certain PSI, usually 90 psi. All the other specs like tank size, max tank PSI, etc. really don't make much difference, other than a smaller tank will kick on and off more often than a larger tank will.

Not sure on the gun, all it says on the gun is UNIPOWER AIR TOOLS. I mean it was free, never failed on taking out any bolts except for this one. Taken out axle nuts easily.

 

How about this... If it's an option.

Toss the motor in the back, take it to a tire place or machine shop... Have them pop it off for you... I couldn't imagine them charging too much, if anything. Save the hassle... :-)

 

You probably need a better gun. Mine is the 3rd one I've had. At first I bought a cheap one from Harbor Freight for like $30. It was a POS. I took it back and got a Husky one from Home Depot for $80. It was a POS also. Finally I got my Ingersoll-Rand gun from Lowe's for about $110 and it has been nothing but great. It puts out more torque in reverse so it will always remove a bolt that it had previously tightened, no matter what.

There you go!!... even lighter to throw around.

 

Can I spray some carb cleaner or pb blaster or something on the pistons? I think it's getting stuck there...since I'm pulling the pistons/rods and the sleeves need to be rehoned anyways will it hurt anything?

 

Go get a 20.00 propane or map gas set at homedepot. Put some heat to it and then try to use the air gun.

Gotta get creative when you DIY.

Some really good **** that I use and love:

or

http://www.crcindustries.com/ei it is called knock'er Loose

 

One thing that helped me was going forward and backward. Yeah, it sounds senseless but I spent a 1/2 hr just trying to back it out. Then I started going back and forth and it was out in 10 minutes.

 

i had the same problem and i ended up using a 5 speed impact gun and it worked. but do not use heat on that bolt. think about the seal on the other side. unless you just dont mind wasteing money. o yea hold breaks to stop engine if it still wont budge.

 

theres a special tool that you use and itll come off.

 

Had that problem, use a propane torch and heat it up. WORKS LIKE MAGIC:D

 

I tried taking mine off a couple weeks ago with an air impact and the gun wasn't strong enough so I took it to a little mechanic shop and the guy took his airgun and unbolted it for me, then bolted up it lightly so that I could drive home and still be able to take it off with just a ratchet. He did it for free, but I had to go to a few different places and ask around and nobody would do it because of liability reasons, but then this one guy that worked at one of the shops suggested to go to the place that finally did it for me.

HAHAHAHAHAHAHA oh man cant stop laughing...anyway i have a 80 gallon with 175 max psi and like a 150 3/4 inch impact...works like a charm...but if you dont have the money do this...

take the starter off, jam a big friggin screw driver in there...put a nice strong breaker bar on the crank bolt slip a long metal pipe over the handle, and viola properties of simple machines...basic science my friend.

did it both ways when i didnt have the inpact and last weekend changed timing belt so bought a nice 3/4 impact and got it off in about 5 seconds on 90 psi...
