Rear stationary bolt broke.... Please help..
Hi from Norway,
During my rebuild of a 13 B NA, one of the 6 bolts of the rear stationary gear broke. I have tried to drill the rest of the bolt out, but with no success so far. My questions: 1) Can I skip this one of the 6 bolts ? 2) Any advice as to get the rest of the bolt out without hurting the threads more that I probably have.... Any comment would be greatly appreciated. Thanks, Oivind |
you could try to groove a slot in the top of the bolt and remove it like a screw.

Thanks for the reply.
Unfortunately I had already started to drill a hole in the middle of the bolt. I guess I will have to continue drilling tomorrow ... Oivind |
Get yourself an easy-out kit. Little guys that look like backwards drill bits, kind of. Drill the hole as deep as you can in the center of the bolt, insert a properly-sized easy-out (should "catch" as you twist it counter-clockwise), and turn CCW with whatever tooling you need on the easy-out.
Most of the time, I use a #8 easy-out, with a #40 drill bit sized hole, a hammer (gets the "grabbing" going quicker if you give it a couple of taps first) and a small crescent wrench to hold & turn the easy-out |
The guy is from Europe - I doubt he's got access to those tools. :)

Thanks for interesting feedback.
What I did was to use too much power on my easy-out kit (or the quality of the steel was bad). The reverse stud broke..... You can imagine how hard it was drilling this piece of steel out of bolt... I have been working on it for an hour, finally I got through the bolt using a diamond type of drill. One of my friends will help me with making new threads, if needed. The welding technique seems really professional. Thanks for the advice! After some frustrating hours, I think I have passed the worse obstacles in the rebuild process... Thanks !! Oivind |

Shit, forgot about the other option...left-hand or reverse drill bits!
You need to find an industrial or machining / milling shop to get them. -Ted |

If it breaks, the one you used was too small, or you applied the wrong directional pressure while turning it (i.e. bent it "sideways")... |
What Wayne88 said. Those things are mandatory in the aircraft maintenance world.
