So what did you guys use to remove the crank pulley bolt? Air impact? Electric impact? Breaker bar? Strap wrench? wedged breaker bar and starter?

My pulley and belt are both here but before I try to install them I'd like to know how hard it is to remove that crank bolt on a auto. I was gonna try a breaker bar and strap wrench but maybe I should get an electric impact wrench instead? TIA.

 

breaker bar and a leangth of pipe for leverage

 

I used an impact gun. After a few hits, it came right off.

 

i know with the gen 1's you can't get in there with an impact. If you can get in there on the gen2's impact gun all the way, just set the tourq to the right psi when re-installing!

 

Thanks guys. I should have been more specific in my question. For instance, if using a breaker bar, how did you prevent the crankshaft from turning? I have an auto so 3rd gear and parking brake won't help.

If you used an impact gun, was it a low-torque electric or a high-torque air impact? Most electric impacts only generate 200-250ft/lbs vs ~600ft/lbs for a good air impact. I don't mind buying an electric impact wrench if it will do the job but an air compressor is out of the question. I could also try a strap wrench and breaker bar but since I'll be working alone, that method could be tough. Thanks again.

 

I just used a medium duty air impact wrench to take off and replace the bolt. i had no settings to torque it down so i just did alittle more than i do with my tires. Not very scientific but i will check again soon.

i used an electric impact. (kawasaki) and it zipped right off. i'm sure that as long as you buy a name brand electric impact you'll be fine...

 

Thanks Renegade and whitebreadbox. That's exactly what I wanted to know. I've heard of cases where electric impacts didn't have enough torque to loosen crank bolts and didn't want to buy one only to find out it wouldn't work.

I ordered the Kawasaki 1/2 impact wrench from Amazon. I'm sure I'll find lots of other uses for it.

 

I used the exact same thing. corded kawasaki impact wrench from pepboys for 70 bucks.

U kinda have to go at it for quite a bit to loosen the bolt it but it works!

And you can't use breaker bar or torque wrench on this since the pulley will turn as you tighten/loosen

 

Thanks.

The Kawasaki impact wrench worked great after I took it apart and removed the loose screw that some underpaid, overworked Chinese worker left in it. I probably should have returned it when I heard the rattling inside but I got it from Amazon and didn't want to wait weeks for a replacement. Anyway, it took the crank bolt out in 15 seconds.

The NST UD pulley is on and the Gates K060750 belt is a perfect fit. By far the hardest part was loosening the idler pulley but I managed to get it by myself. Took about an hour.
