| Attempting to clean up and repaint my 45 year old 300421. Got to the last headbolt and no go. Turned very tough for about 15 degrees when I decided I should stop. What do I do next? Thanks for any help. |

Couple of things. Flood the area around the bolt with penetrating and let it set over night. Then try turning the bolt back and forth to work the oil down around the threads. Keep adding penetrating oil and you should be able to work it the rest of the way out. If it stops turning start the process over again from that point.
I don't know if you have an impact driver (not an impact gun) or not but this can be use also. install a 3/8th's drive socket to fit the head of the bolt. Use penetrating oil and drive the bolt in and out until it loosens up. An impact gun can be used also but you need to keep it turned down so you don't twist off the bolt.
Good luck. |

| Chris, my Ridgid impact driver has 120 foot pounds, and I've broken off 5/16" bolts with it. But then it's variable trigger. Chris guided you right Mike! |

Try the old stand by 50% ATF 50% Acetone mix, for penetrating oil. It works better than any commercial product know to man!
Let it work for at least 24 hours, then try to work the bolt back and forth. I would not use an impact gun of any sort, if the bolt snaps you are in for a lot of work as you well know.

| Using a tiny ball peen hammer (or any tiny hammer), tap the bolt head several times "lightly" after applying whatever penetrating oil you use. Work it back & forth a few times, then repeat the whole process again & again until she comes out. |

Never use force, always use a bigger hammer! |
