PWA85368 is a self‑lubricating high‑load bushing for aviation maintenance tools and ground support equipment, engineered for heavy‑duty pivot, lift, and actuation systems. Manufactured to AS9100D standards, it is made from oil‑impregnated sintered bronze with a wear‑resistant surface, supporting high radial and axial loads without external lubrication. It resists dust, moisture, Skydrol, jet fuel, and deicing fluids, while reducing friction and maintenance needs. With standard shaft and housing dimensions, it enables drop‑in replacement, ensuring smooth, long‑lasting articulation, extending service life, and minimizing downtime in hangar and tarmac MRO operations.

Overview
The PWA85368 is a high-performance, heavy-duty Arm Lifting and Engine Assembly Support Tool custom-engineered for the rigorous maintenance, repair, and overhaul (MRO) of commercial jet engine powerplants. Classified as a critical powerplant-handling Ground Support Equipment (GSE) asset, this specialized lifting arm is purpose-built to safely anchor, balance, and hoist the engine assembly specifically at the No.1 and No.1-1/2 bearing support structural bays. Manufactured by JUNXUN to comply with strict aerospace dimensional criteria and weight-distribution profiles, the PWA85368 establishes an absolute, rigid mechanical link that allows workshop technicians to execute fluid vertical transitions and horizontal indexing without introducing airframe skin stress, housing distortion, or geometric misalignment to flight-critical rotor shaft systems.

Key Points
Targeted Bearing Station Interfacing: Custom-machined to clamp seamlessly onto the standardized casing index lips, hoist points, and flange patterns proprietary to the engine No.1 and 1 1/2 bearing support architectures.

High-Tensile Rigging Stability: Fabricated from premium, proof-tested structural alloy steel engineered to withstand intense static and dynamic lifting forces without structural deflection, thread stripping, or joint deformation.

Micro-Level Load Distribution: Features an engineered cantilever arm geometry designed to optimize the lifted center of gravity (CG), ensuring the heavy engine module remains perfectly level during crane transit.

Non-Marring Precision Passivation: Outfitted with specialized contact-surface treatments and protective backings to completely eliminate scratch hazards against high-value titanium forgings or internal acoustic panels.

Applications
Core Engine Teardown & Rebuild MRO: Utilized by certified powerplant technicians as the primary hoisting adapter to support and manipulate the forward bearing modules during scheduled heavy maintenance checks.

Rotor Shaft Alignment Workshops: Deployed within specialized engine overhaul cells to hold the bearing support housings perfectly rigid during the replacement of main carbon seals and roller bearings.

Airlines Maintenance Tool Crib Support: Essential hardware for international airline engineering hubs and third-party overhaul facilities to complete rapid engine module separations safely and reduce turnaround times (TAT).
