About this file
This is a technical engineering drawing for a Backing Plate (Part Number 200037001-1) developed for the U.S. Air Force by the Defense Supply Center, Columbus. The backing plate is a 4130 alloy steel component designed for use in a BAK-12 Clutch assembly, with a cage code of 98752. The drawing specifies a circular plate with a bolt circle diameter of 5.125 inches containing 10 holes (0.453 inches through), dimensions of approximately 12.75 inches outer diameter, and a thickness of 0.438 inches. The material must comply with AMS E4340, AMS 51, or AMS 45 specifications.
The component requires comprehensive surface finishing, including a Sherwin Williams zinc clad coating (0.5-5.0 mils dry film thickness) followed by two coats of Sherwin Williams Acrylon 218 HS polyurethane topcoat (5.0-6.0 mils dry film thickness) in color #405 (olive drab green) per FED-STD-595. All dimensions and tolerances conform to ANSI Y14.5M-1994 standards, with specified tolerances of ±0.01 inches for two-place decimals, ±0.004 inches for three-place decimals, and ±0.5 degrees for angles. The drawing has undergone multiple revisions and was approved by Todd M. Balducci. The part is manufactured to MIL-STD-1006 standards and is approved for public release with unlimited distribution.
