The Rolls-Royce (Allison) Oil Transfer Tube, Part Number 6856067, is a critical aircraft turbine engine component designed to transfer lubricating oil between the engine housing and the oil pump module. Offered in used (as removed) condition, this part has been previously installed and removed from service and is intended for inspection, evaluation, repair, or overhaul in accordance with approved aviation maintenance procedures.

Oil transfer tubes are essential to the lubrication system of a turbine engine. They ensure continuous and controlled oil flow to critical rotating and bearing assemblies, helping to reduce friction, manage heat, and prevent premature wear. Reliable oil circulation is vital for maintaining engine efficiency, operational stability, and long-term component life. Any restriction, leakage, or misalignment within the oil transfer system can significantly impact engine performance.

Part number 6856067 is manufactured to precise aerospace tolerances to ensure proper routing, fitment, and sealing within approved engine configurations. Oil transfer tubes must withstand vibration, pressure variation, and thermal cycling while maintaining structural integrity and internal cleanliness. For this reason, these components are typically produced from durable, corrosion-resistant materials designed for continuous exposure to engine oil and elevated temperatures.

This oil transfer tube is associated with turbine engine systems developed by Rolls‑Royce, including Allison-origin engine platforms widely used in helicopter and light fixed-wing aircraft. During maintenance and overhaul activities, oil transfer tubes are carefully inspected for cracking, deformation, internal contamination, and seal interface condition to ensure proper oil flow and leak prevention.

As an as removed component, the 6856067 oil transfer tube is well suited for MRO facilities, repair stations, and aviation parts distributors supporting repairable inventory programs or exchange pools. Final determination of serviceability must be made following detailed inspection and any required reconditioning by qualified aviation maintenance personnel.

Installation and approval for return to service must be completed in accordance with applicable engine maintenance manuals, oil system specifications, and regulatory authority requirements. Proper handling and cleanliness are essential to prevent contamination of the engine lubrication system.

The Rolls-Royce (Allison) Oil Transfer Tube 6856067 remains an important lubrication system component for turbine engines where reliable oil delivery, system integrity, and compliance with original manufacturer specifications are essential.
