Overview

The 856A3276G01 is a high-performance, precision-engineered Strengthening Ring and hydraulic interface assembly custom-designed for the rigorous maintenance, structural repair, and overhaul (MRO) of commercial turbofan low-pressure turbine (LPT) casings. Positioned at the critical structural juncture of the LPT case rear flange, this specialized hardware serves as a dual-purpose heavy-duty reinforcement fixture and high-pressure fluid-containment interface. Manufactured by JUNXUN to comply with strict aero-engine technical parameters and micro-tolerance indexing specifications, the 856A3276G01 provides an absolute rigid backing that redistributes bolt-tightening loads uniformly, preventing dynamic casing distortion, flange face scoring, or pneumatic pressure bypass during scheduled ground static pressure and containment diagnostics.

Key Points

Dedicated LPT Casing Profile Mating: Custom-machined to clamp seamlessly onto the standardized rear flange bolt-hole circles and indexing lips proprietary to commercial high-bypass engine architectures.

Integrated Precision Hydraulic Porting: Outfitted with heavy-duty, leak-free hydraulic coupling ports engineered to interface directly with external tensioning pumps for synchronized multi-bolt preloading.

High-Tensile Aerospace Alloy Construction: Fabricated from premium, heat-treated high-strength alloy steel certified to withstand immense mechanical shear and internal pressurization forces without geometric deflection.

Non-Marring Ground Seal Interface: Features closely toleranced, passivated mating surfaces and elastomeric backup matrices that prevent metal-on-metal scratching and eliminate pressure loss across the flange interface.

Applications

Turbine Module Disassembly & Rebuild MRO: Deployed within specialized engine repair facilities to reinforce and balance the LPT outer housing while technicians secure or release high-torque rear structural fasteners.

Hangar Engine Case Pressure Diagnostics: Utilized as a primary pressure-blanking and fluid-injection fixture during hydrostatic or pneumatic sealing audits of the aft propulsion sections.

Airlines Engine Tool Crib Fleet Logistics: Essential specialized tooling inventory for global commercial airline engineering hubs and third-party powerplant MRO facilities to ensure compliant, safe engine module overhauls.
