I am in the process of replacing the rings and bearings in my d16y7 dd, I've taken many Honda crank pulley bolts off before, but this one is being impossible, I hit it with my IR air impact, a new 650ft/lb air impact I bought today just for this, and two grown adults with pipes and breaker bars. This just refuses to come off, please help!

3/4 inch air gun. i bought one just to get some crank pulley bolts off a few years ago. other than that...with your impact gun, make sure compressor air pressure is all the way up and try hitting the bolt clockwise and counter-clockwise a few times. i would only do it for maybe 15-20 seconds at a time or the bolt will get hot and your air compressor will probably be ready for a recharge anyways. if that doesn't work i don't know what to tell you lol. they are a pain sometimes.

spray some pb blaster and let it soak overnite then use your gun. or a pry bar at the flywheel and breaker bar at the pulley bolt. its always a bitch to take it out! FML too

no no if that IR gun isnt breaking it loose either a stronger gun and higher pressure might work... i have an IR with almost 900 ftlbs break away torque at 120 psi and ive had trouble taking a few off, but they come off with patience and know how.

Crank pulley tool, two big guys and some breaker bars should break it loose. Spray PB Blaster too

If the above does not work...well I hate to admit it but I had to put heat on mine...I bought the tool from napa to hold it in place and everything did not work...borrowed a 3/4 drive and I have an ir nada...put a lil heat on it for just a lil bit make sure your pressure is maxed and as stated before hit it for 15-20 seconds....you may also want to try the back and forth technique...i e switch the reverse/forward button in quick pushes...my 2 cents...good luck...took me like a week of trying on my b16 I got from jhot imports...true p.i.t.a. for those that don't agree I concur I only did as a last resort but the motor is boosted and still running on stock internals....

do the back and forth thing with a very powerful air gun like turbo civic and i said. if that doesn't work use heat, but not for more than 15-20 at a time with a torch. if the bolt is glowing it's way too hot. you want it just starting to get orange. do not hold the torch in the same spot for more than a second, move it around and heat evenly. replace the crank seal/oil pump seal if you use heat to get it off or it will most likely leak.

i think my ir 3/4 gun is rated for 1200 ft-lbs. it's the most powerful one you can get, i know that, just a few years old. bought it just for crank pulley bolts lol

Crank pulley bolts are a bish lol. I have an Orthodox Pulley on the GSR I picked up and that **** has to go, but it wouldn't budge from my Dewalt. It's time for some breaker bars, crank tool and my 260lb roomate lpl
