OK, let's try again.

I removed the nose gear torque tube from 28747.  

I stripped all of the paint.

Under the paint in a few places is rust.  

One place is at a joint . .  I'll investigate that today.

On the inboard are two bolts, one on each side of the center.

There are brackets on either side of center.  These brackets are held together by AN bolts.

Inside of the brackets is a collar. 

The surface of the brackets that sits on the collar have some rust.

I would like to sand off the rust and paint the inside of these brackets.  Problem is the bolts prevent me from moving the brackets very far apart.

I've never had one  apart before.

Can I remove these bolts?

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.

Bummer.  I'll have to do the best I can.
