Allison Rolls-Royce Oil Collar Seal Carrier | P/N 3015871A

The Allison Rolls-Royce Oil Collar Seal Carrier, Part Number 3015871A, is a precision-engineered aircraft turbine engine component designed to support and retain oil sealing elements within the engine lubrication system. Seal carriers play a critical role in maintaining proper oil containment, pressure control, and leak prevention in high-speed rotating engine assemblies.

In turbine engines, oil collar seal carriers provide structural support for seals that isolate lubricated bearing areas from adjacent engine sections. Proper sealing is essential to prevent oil migration, reduce contamination, and ensure stable lubrication of bearings and rotating components. A properly fitted seal carrier helps maintain oil system efficiency while protecting surrounding engine structures from heat and oil exposure.

Part number 3015871A is manufactured to strict aerospace tolerances to ensure precise alignment, secure seal positioning, and compatibility with approved Allison-origin engine configurations. Components in the oil system must withstand continuous vibration, thermal cycling, centrifugal forces, and long-term exposure to engine oil. For this reason, oil collar seal carriers are typically produced from high-strength, corrosion-resistant materials capable of maintaining dimensional stability under demanding operating conditions.

This component is associated with turbine engine platforms originally developed under Allison and now supported by Rolls‑Royce. These engines are widely used across helicopter and fixed-wing aircraft, where dependable lubrication system performance is essential for safe and efficient operation.

During maintenance and overhaul activities, oil collar seal carriers are carefully inspected for wear, surface damage, distortion, and interface condition to ensure proper seal retention and oil containment. Correct part selection and installation are critical to preventing oil leaks and ensuring long-term engine reliability.

The Allison Rolls-Royce Oil Collar Seal Carrier 3015871A is suitable for aviation maintenance organizations, engine overhaul facilities, and parts distributors supporting turbine engine lubrication system maintenance. Final determination of serviceability and approval for installation must be completed by qualified aviation maintenance personnel in accordance with applicable engine manuals and regulatory authority requirements.

The Allison Rolls-Royce Oil Collar Seal Carrier P/N 3015871A provides a reliable solution for turbine engine oil system applications where precision, durability, and compliance with original manufacturer specifications are essential.
