Hard bolt removal

[Silverrider]

I have met my match, I am working on a XB 2010 and I cant get the last bolt out of the rear pulley, the ones I did get out have blue loctite on them, I have put the heat to it and still broke 2, T45 star bits. Any suggestions ??

If heat and soaking suspect bolt/screw with penetrating oil aren't working try a hand held impact tool.
Something similar to this:

I used my Dewalt 18 V impact, thats how I broke my first bit with, I need to go buy more bits just to put the others back in .

both the rear pulley bolts and rotor bolts have factory loc-tite type thread sealant on them. perhaps do what i did years ago and buy the finest T45 3/8th inch drive tool you can find and be done with it. got mine from local snap-on driver and has been flawless plus lifetime warranty. i first loosen those pesky rear pulley AND front rotor bolts by hand....then once loose run them out with air impact. i do NOT use an impact to initially loosen them....only long handle ratchet driver.

Yes, I have been using Kobolt from Lowes , Life warranty, . I will try a better quality tool, Thx guys.

Yeah, you can get away with using the lesser quality tools 90% of the time. Then you run into that last fastener that won't budge, that's when one must move up in quality and, that usually means Snap-On.

I have put the heat to it

I have, in the past, had the same issues. What type of heat are you using, and how are you applying it to the bolt? I have found that using an oxy-acetylene torch with a small tip directed to the center of the bolt head until you develop a red dot works. Once you have done this allow it to cool down before using the T45 socket. When you get the bolt out throw it away and purchase a new one. Sometime you have to do the heat cycle a couple of times before it breaks free.

Good luck.

:up: Don't know if it would have helped, my a buddy of mine who is a retired airplane mechanic swears by Mouse Milk as the best penetrating oil of all time. I guess they use it all the time for really hard to get off bolts on airplanes.

I have a penetrating oil ( only a little left, less than an ounce ) that will unseize a seized engine, it was on all moving equipment that went to Dessert Storm. I've sent it loosen a bolt that torches couldn't break, my friends call it " the nuclear stuff "

I bet you only have a little left cuz it penetrated out of the bottle. LOL
