The Multiquip 5133111141 is a genuine OEM Rocker Oil Feed Pipe designed for the DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator series. As a direct OEM component, it is manufactured to the exact specifications of the original part, ensuring a proper fit within the engine's valvetrain oiling circuit. Sourced directly from Multiquip, this part carries the same part number — 5133111141 — used by authorized service technicians, so you can order with confidence that you're receiving the correct component for your machine.

Key Features

• Genuine OEM Oil Delivery Accuracy — Engineered to maintain the precise flow rate and routing path required by the engine's rocker arm oiling circuit, avoiding the lubrication inconsistencies that can come from improperly sized replacement pipes.
• Direct Drop-In Fitment — Matches the original mounting points and connection interfaces within the engine, allowing straightforward installation without reworking surrounding components.
• Confirmed Compatibility — Verified for the DCA25SSI, DCA25SSI2, DCA25SSIU, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator models.
• Protects Valvetrain Components — Consistent oil delivery to the rocker arms prevents accelerated wear on rocker arms, push rods, and valve stems, helping the engine maintain proper compression and smooth operation.
• Correct Part Number Reference — Listed under Multiquip part number 5133111141, matching factory service documentation for the DCA25SS series engines.

The rocker oil feed pipe is a small but critical part of the engine's internal lubrication system. Its job is to route pressurized oil from the engine block up to the rocker arm assembly, ensuring the rocker arms, valve stems, and related valvetrain components receive a steady supply of lubrication during operation. When this pipe cracks, becomes blocked, or develops a leak, oil delivery to the rocker assembly is compromised — leading to increased friction, accelerated wear on valvetrain components, and in severe cases, engine damage from heat and metal-to-metal contact. Replacing a damaged or leaking rocker oil feed pipe promptly is essential to maintaining engine health and consistent generator output.
