0414799008 New Aftermarket Unit Pump fits Mercedes-Benz OM904 OM906 – GOTTO PARTS

Product Specifications:

Engineered to restore peak injection pressure and fuel economy for heavy-duty commercial freight, transit buses, and extreme off-road operations, the 0414799008 is a premium aftermarket PLD Unit Pump. Explicitly designed to fit the robust commercial trucks, buses, and specialty vehicles powered by the OM904, OM906, OM924, and OM926 engines (including Atego, Axor, Unimog, and Citaro models), it ensures relentless durability under extreme payload and torque demands. Featuring a true Plug & Play (No Coding Required) architecture built to exact factory parameters, it bypasses complicated ECU calibration steps for a seamless direct-fit installation. We strongly warn against replacing only a single unit; mixing old and new pumps creates severe fuel pressure imbalances that directly lead to catastrophic engine failure, including cracked cylinder heads and melted pistons. Protect your heavy-duty engine block and reduce downtime by leveraging our Tiered Pricing to upgrade the complete 4-cylinder or 6-cylinder pump set today.

👨‍🔧 Tech Notes & Installation Guide (FAQ)

Q: Why should I replace the full set of 4 or 6 unit pumps on my OM904 / OM906 engine?

A: Mixing old and new unit pumps creates extreme fuel pressure imbalances across the cylinders. This leads to rough idling, heavy vibration, and a high risk of catastrophic engine failure such as cracked cylinder heads or melted pistons. Replacing the full set ensures balanced torque output, and you instantly save money through our Tiered Pricing bulk discount.

Q: Does the 0414799008 unit pump require IMA coding?

A: No coding is required. As a PLD unit pump, it is manufactured to precise mechanical tolerances for a pure physical direct fit. It operates entirely as a Plug & Play (No Coding Required) system, relying on mechanical cam actuation to deliver fuel without the need for complex IMA software pairing.

Q: What is the critical cleaning step before installation?

A: You must completely flush the high-pressure fuel lines and system to eliminate all microscopic metal debris. Furthermore, it is mandatory to install a brand new 5-micron diesel fuel filter before cranking the engine to prevent immediate contamination and valve scoring in the new pump.
