From what I understand, the main purpose of the torque strut is to maintain wheel alignment. It will move back and forth just a little to absorb loads on the two landing gear struts. There is no need for pressure inside the unit.
Unfortunately, there is very little info in the tech orders.
Railrunner is correct, the fittings have been installed on the rear and front beams since Christ was a corporal, I do believe. They are in the drawing dated 1958. We had electronic pods for the E-model birds we had at Ramstein that went out there. Don't know any weight limitations.
Don't know anything about blue paddle lights. Here is the purpose statement from the TCTO. This TCTO wasn't even issued until 2001.
"The purpose of this Time Compliance Technical Order (TCTO) is to document the installation of
Night Vision Goggle (NVG) compatible cockpit lighting by replacing selected lens covers and
caution/warning lights with replacements already in use by other C-130 airplanes. This action will
provide optimal visual acuity for crewmembers using NVG and permits use of NVGs by aircrews
throughout entire mission profiles without measurable degradation and within the airplane’s full
performance envelope."

I would guess that every 10 percent is 3.5 degrees, that's using old math. I don't know how it would come out using common core math. Can't find anything on clearance.
All equipment on the bird is manufactured to work +/- 20 Hz. This is out of the -23GS:
40 kVA Engine-Driven Generator
The phase-to-phase voltage is 200 VAC. The generator is connected as a 3-phase wye circuit with a grounded neutral. The output frequency range is from 380 to 420 Hz.
I really don't see the reason for it, but it is in all of the books. Maybe it has something to do with the 3 phase power used by the cargo compartment recirculation fan.
