munirabbasi Posted September 27, 2016 Share Posted September 27, 2016 Hello world expertise How main landing torque strut (MLG Torque STRUT) works internally, how cylinder retain its original position without spring/air/hydraulic. regards Munir Abbasi Quote Link to comment Share on other sites More sharing options...
tinyclark Posted September 27, 2016 Share Posted September 27, 2016 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.

munirabbasi Posted September 28, 2016 Author Share Posted September 28, 2016 tinyclark how it back its original position i.e neutral position, please describe internal function of cylinder, I thank i works like bellow regards munir abbasi Quote Link to comment Share on other sites More sharing options...
tinyclark Posted September 29, 2016 Share Posted September 29, 2016 I wish I could explain it any better. The MLG struts wouldn't have much movement front to back, so there wouldn't be much travel in a bellows, as you stated. Again, there is no better instruction in any books that I have seen. We avionics folks call it FM, Frikkin' Magic. Quote Link to comment Share on other sites More sharing options...

Tiny is correct on both counts.Once the weight is off the gear it will hang to a pretty much neutral position.On the ground on a straight ahead taxi the side loads will drop to "0" after just a few feet of travel.The fore/aft loads will be taken care of by the pins when they engage the shelf brackets.(remember those pesky shelf bracket bushings?)

Student1 Posted November 4, 2016 Share Posted November 4, 2016 Okay so one of the people above me asked me for a job guide on mlg wheel alignment. Now idk if he is just messing with me as a joke or this is a serious thing. Everyone I work with thinks he is sending me on a wild goose chase. So idk. I would appreciate an answer though. Thank you.

tinyclark Posted November 6, 2016 Share Posted November 6, 2016 How about a gallon of prop wash and 50' of flight line. All tasks are listed in the 1C-130H-2-00JG-00-1. Quote Link to comment Share on other sites More sharing options...
Luca11271 Posted November 10, 2016 Share Posted November 10, 2016 Years ago I had the chance to disassemble all the torque struts of our fleet in order to perform a detailed NDI inspection and can conferm it's just a piston free to move inside a cylinder. Its purpose is to keep the wheels perfectly aligned both on and off ground. Drag pins, once they are engaged in the shelf bracket, lock the shock struts in DOWN position but the cylinders, with the wheels attached, would be free to spin without the Torque Strut conecting them each other. The extension of the Torque Strut is enough to have one gear completely extended and the other one completely retracted with no interference.

tinyclark Posted November 13, 2016 Share Posted November 13, 2016 Thanks, Luca, makes complete sense. Quote Link to comment Share on other sites More sharing options...
