Default Nuts and bolts.

Working up the nerve to replace my original nuts and bolts with the new ones with retainers (going to flip the bolt). My 8 does not have the gear tower mod and there's lots of stuff runnng through that area. Any words of wisdom or is it just bleed and cuss time? I am going to use my rivet gun with an offset to just bump them out. I know you have to modify the retainers slightly to clear one nut. Any other hints? I'm at the point in the condition inspection where I need to torque the nuts so, I guess, it's just time to dive in, do the mod, and be done with it.

Hi Rob,

Yes, some have done it w/out the gear mod. https://vansairforce.com/community/s...d.php?t=130904 Brush up on your yoga or shove your grandson up front under the panel!

I have a cheap bore scope, and that's been pretty helpful at seeing inside the towers. I think the biggest obstacle will be on the rear gear bolt and interference with the vent line coming through the fuselage. I believe it will have to be removed. If you want, send me an email and I'll send you some photos of the inside my towers.

Brian

Default I have spares

I have spare NAS6606-27 bolts and NAS1804-6 nuts. I purchased a 10-pack from Military Fasteners and only need four plus a spare.

My cost with was $9.74 for each nut plus bolt. Ping me if you want four or five at say $8 each plus postage.

Cheers,
Bob

I'm looking for a set of NAS6606-27 bolts and NAS1804-6 nuts. If there's some spares floating around, I'll take them off someone's hands.

I plan on installing NAS6606-27 bolts and NAS1804-6N nuts at my next condition inspection in June. Hopefully with the bolts in from the top. I expect friction drag added to the 240 inlb torque will probably be somewhat higher than the NAS679A6 nuts, since the NAS1804-6N is self locking and has longer thread engagement.

Anyone know what friction drag to expect?

You're expecting them to just lock up on top and not need to use a tool or anything to hold it from the top? If so then you're the first person I've read about who thinks this.

I bought some wedges someone made exactly to avoid the spin and not need a tool.

I have the bolts, nuts, and those wedges for sale if anyone needs them. I didn't need them and later sold my plane.
