SonnyJ Posted September 5, 2008 Share Posted September 5, 2008 Which part number ballscrews? Quote Link to comment Share on other sites More sharing options...
victorp1 Posted September 5, 2008 Share Posted September 5, 2008 I have not located the tech data but I remember 27 inches. It has been about 20 years ago, I was a FE on the Navy LC\'s. I will follow-up if I find a different number. Vic Quote Link to comment Share on other sites More sharing options...

A97Stallion Posted September 5, 2008 Author Share Posted September 5, 2008 thanks for your help guys I will confirm the part number (Calco type), but where is that figure from (manual reference) and is this set at the repair center, therefore all ready set up when the item is installed on the aircraft, or can you/do you set this dimension as required?

victorp1 Posted September 6, 2008 Share Posted September 6, 2008 I could not find a spacific value but after looking at USAF TO 1C-130H-2-32GS-00-1 I found the following in paragraph 2-2.2.7: \"The ballscrew and pillow block on LC-130H airplanes is the same as other airplanes except for two differences. The ballscrews are provided with upper bumper stop extension tubes to restrict gear retraction at the point where the main skis mate with the ski fairings. The mating point is approximately 27 inches lower than the full gear retraction level if skis were not installed. Also, the trunnion cap attaching screws are spring- loaded with ring springs. During nose-high landings, a downward force is exerted on the forward part of the main skis at touchdown. Since the main gear shock struts are fully extended at this time, the ring springs allow the lower strut support to bottom on the shelf bracket to relieve the load on the trunnion cap attaching screws.\" Vic Quote Link to comment Share on other sites More sharing options...
