We have almost 200 separate documents relating to all types of aircraft wheels, brakes, struts, and landing gear in general - browse here.Engine lubrication system diagram.
#Bendix aircraft manual manuals#
Bendix tail wheel manuals were indicated by a “2”: TO 4W 2-3-23 ( Tail Wheel 10.5 x 4, Type II), while nose wheels were distinguished by a “3”: TO 4W 3-6-43 ( Nose Wheel 22 x 7.25-11.50, Type VI).īendix wheel information is just a small portion of the information we have relating to landing gear. For example, I noticed that all the documents with a “1” following the “4W” related to Bendix Main Wheels: TO 4W 1-4-123 (for Main Wheel 26 x 6.6, Type VII) and TO 4W 1-3-3 (for Main Wheel 30 x 5, Type II). Grouping Like Bendix Wheels TogetherĪnother thing that I noticed when adding this group of manuals to the site was how the different types of Bendix wheels were grouped together by their new document number, after 4W-1-31 was broken up. From the titles of these smaller supplements you will notice that Bendix wheels were distinguished by size and a roman numeral “type” distinction for each wheel, for example: Main Wheel 17:00-20 (type III), Nose Wheel 27 inch (Type I), Tail Wheel 10.5 x 4 (Type II), the list goes on and on. Once 4W-1-31 was broken up, each supplement that was taken from it pertained to a specific model of Bendix wheel, whether it was a main, nose, or tail wheel.
As time progressed, systems and components were becoming more and more complicated and it was natural that manuals were separated into more detailed sections that eventually became their own document with a unique document number. The big change clearly happened on 1-March-1955, when 4W-1-31 was broken apart into separate smaller documents. The Air Force returned to the “TO” distinction (from AN) in the early 1950’s - read more about this change, and the tech order system by clicking here. TO 4W-1-31 & Subsequent ChangesĪs changes in the military Tech Order System evolved, the document number AN 03-25BB-1 would have been updated to TO 4W-1-31, and at that time would likely have contained the same information.

This manual would have covered many different models of Bendix wheels, and I’m imagining it was pretty large. Long story short, the title of AN 03-25BB-1 is “Operation, Service, and Overhaul Instructions with Parts Catalog for Bendix Main, Nose, and Tail Wheels". We have several versions of the Alphabetical index, along with multiple versions of its counterpart, the “ Numerical Index of Technical Publications”, both of which I use on a regular basis. Using the “ Alphabetical Index of Technical Publications” (an invaluable resource) I was able to determine the title of AN 03-25BB-1 without having a copy of this manual on hand. On the cover of almost every manual that I was processing, I noticed the same disclaimer: “This publication replaces in part T.O.
This week I came across something interesting when uploading over 35 new Bendix wheel manuals to the AirCorps Library website. Many people are interested in landing gear components - I get questions about it all the time. So many wheels, so little time: Breaking down a comprehensive Bendix wheel manual into smaller supplements Wheels, Brakes, & Struts
