| Subject: | Nose gear torque tube. |
Bob,
I stripped the paint off the torque tube and found a few locations of rust. Can
I remove the bolts near the center to expose the tube where the collar sits?
I've never taken one apart before.

I have some better ones, but will have to keep digging for them.

If yours has the shear bolts at the inboard ends, you can't get the brackets too
far apart.

They are shear bolts, and the holes are reamed to a drive fit. If you remove them
(which you may need a big hammer to drive them out), it may leave the holes
oversized. I don't think they are considered field serviceable.
The only ones I've taken apart are ones that are going in for repair.

The NAS shear bolts are not field serviceable, in my opinion. Not sure how you'd
get to them while the torque tube is in place. After taking the assembly out,
one would need either a press or a hammer to push them out, and the holes may
be damaged in the process.
There may be data on oversize bolts, but I don't have access to it. Perhaps Garner
Rice, or Frank Johnston's son-in-law, now that Frank and Patricia have both
died, may have that data.
I'd be very wary of any rust on such a highly stressed part.
