Manufactured in the United States under CAGE code 97153, this piston housing is available as a direct OEM replacement and is 8130-3 eligible for use in FAA maintenance documentation programs. ECCN is 9A991.d and Schedule B code is 8807200010.\u003c\/p\u003e\u003cp\u003eAircraft brake piston housings contain the hydraulic pistons that apply clamping force to the brake disc stack during braking operations. The housing provides the pressure boundary for the brake hydraulic circuit and must maintain bore dimensional accuracy to ensure proper piston travel, seal engagement, and leak-free operation across the hydraulic pressures applied during brake actuation. The housing material and surface finish must be compatible with the brake hydraulic fluid type and must resist wear from piston travel over the service life of the brake assembly. The 74-830 measures 1.07 x 1.00 x 1.00 inches and weighs 0.05 lb. This piston housing ships as a single unit ready for installation per the applicable component maintenance manual.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e74-830\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eGoodrich Wheel \u0026amp; Brake\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Type\u003c\/td\u003e\n\u003ctd\u003eBrake Piston Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\u003ctd\u003e1.07 x 1.00 x 1.00 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.05 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eECCN\u003c\/td\u003e\n\u003ctd\u003e9A991.d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSchedule B\u003c\/td\u003e\n\u003ctd\u003e8807200010\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Goodrich Wheel and Brake","offers":[{"title":"Default Title","offer_id":46095078097032,"sku":"74-830","price":405.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0331\/9391\/8600\/files\/noimage_2048x2048_1f06d499-08ac-47b0-a9f0-36680698de2d.webp?v=1780934692","url":"https:\/\/www.pilotshq.com\/products\/goodrich-wheel-brake-brake-piston-housing-74-830-oem-replacement","provider":"Pilots HQ LLC.","version":"1.0","type":"link"}
