Understanding the Mercedes-Benz OM471 Engine
The OM471 is a 12.8-liter, six-cylinder inline diesel engine designed for heavy-duty applications. Introduced in 2011 and now in its third generation (as of 2022), it boasts up to 530 hp, 2600 N·m of torque, and a 4% fuel efficiency improvement over earlier models, thanks to advancements like an optimized piston geometry and a 20.3:1 compression ratio. Its compliance with Euro VI emissions standards makes it a favorite for environmentally conscious fleets.
The piston assembly is the heart of the OM 471, translating combustion energy into mechanical power. Key components include the steel piston, piston rings, piston pin, and connecting rod bushing, all engineered to withstand peak ignition pressures of 250 bar. Using OEM parts ensures these components meet Mercedes-Benz’s exacting standards, maintaining performance and longevity.

Why Choose OEM Mercedes-Benz OM471 Piston Parts?
When replacing piston parts, OEM components are the best choice for several reasons:
- Perfect Compatibility: OEM parts are designed specifically for the OM 471, ensuring a seamless fit. For example, the piston’s 132 mm diameter and cooling duct design are tailored to the engine’s unique requirements.
- Uncompromising Quality: Manufactured to Mercedes-Benz’s rigorous standards, OEM pistons use high-grade steel and advanced coatings to handle extreme conditions, unlike some aftermarket parts that may wear prematurely.
- Warranty Protection: Using OEM parts preserves your truck’s warranty, while aftermarket parts may void it, a critical consideration for fleet operators.
- Fuel Efficiency and Emissions: The OM471’s piston design contributes to its 4% fuel savings and Euro VI compliance. OEM parts maintain these benefits, reducing operating costs and environmental impact.
- Long-Term Savings: While OEM parts may cost more upfront, their durability reduces repair frequency, lowering the total cost of ownership (TCO). As Karin Rådström, CEO of Mercedes-Benz Trucks, has emphasized, the OM471 is engineered for cost efficiency over its lifespan.

How to Choose the Right OEM OM471 Piston Parts
Selecting the correct piston parts for your OM471 engine requires careful consideration. Here’s a step-by-step guide to ensure you make the right choice:
1. Identify Your Engine Variant
The OM471 comes in multiple configurations (e.g., Euro VI, EEV, Euro V), each with specific piston requirements. Check your truck’s documentation or use the Mercedes-Benz Electronic Parts Catalog (EPC) to confirm your engine’s variant and part numbers. For example, the third-generation OM471 uses a piston with a 20.3:1 compression ratio, distinct from earlier models.
2. Understand the Components
The OM471 piston assembly includes:
Piston: A two-piece steel design with a cooling duct and 132 mm diameter.
Piston Rings: First ring, second ring, and oil scraper ring for sealing and heat transfer.
Piston Pin and Circlip: Connects the piston to the connecting rod, secured by a circlip.
Connecting Rod Bushing: Reduces friction at the rod’s small end.
Each component must match your engine’s specifications. Volgen Power provides detailed part descriptions to simplify selection.
3. Verify OEM Authenticity
Counterfeit parts can damage your engine. Look for:
Official Mercedes-Benz part numbers (e.g., A471030XX).
OEM packaging and certifications.
Trusted suppliers like Volgen Power, which guarantees authenticity and offers documentation.
4. Consider Piston Kits
For major repairs, opt for a complete piston kit that includes the piston, rings, pin, and circlip. Kits ensure compatibility and streamline installation. Volgen Power offers OM471 piston kits with competitive pricing and lifetime replacement guarantees on select items, similar to industry leaders like FCP Euro.
5. Compare Suppliers
Choose suppliers with a strong reputation, fast delivery, and reliable customer support. Volgen Power stands out for its focus on heavy-duty truck parts, offering free express delivery on qualifying orders and expert guidance.
6. Check Warranty and Return Policies

Step-by-Step Guide to Installing OEM OM471 Piston Parts
Proper installation is critical to maximizing the performance of OEM OM471 piston parts. While professional installation is recommended, experienced mechanics can follow these steps:
Tools Needed
Torque wrench (for precise bolt tightening).
Piston ring compressor.
Feeler gauges (for ring gap measurement).
Low-viscosity engine oil (as specified for OM 471).
Mercedes-Benz Workshop Information System (WIS) manual.
Installation Steps
- Preparation: Disconnect the battery, drain the coolant and oil, and remove the cylinder head and oil pan to access the pistons. Consult the OM 471 WIS manual for detailed procedures.
- Remove Old Components: Carefully detach the connecting rod and remove the old piston assembly. Note the orientation of rings and pins for reference.
- Inspect the Cylinder: Check cylinder walls for scoring or wear. If damaged, consult a professional for reboring or sleeving. The OM 471’s cylinder bore is 132 mm, requiring precise measurements.
- Install New Piston Parts:
- Lubricate the piston, rings, and pin with low-viscosity oil.
- Use a ring compressor to install piston rings, ensuring correct orientation (e.g., top ring facing upward).
- Insert the piston into the cylinder, aligning it with the connecting rod.
- Secure the piston pin with the circlip and torque the connecting rod bolts to 200 N·m (per Mercedes-Benz specs).
- Reassemble the Engine: Reinstall the cylinder head, oil pan, and associated components. Verify timing and valve settings using diagnostic tools.
- Test the Engine: Start the engine at low RPMs, checking for leaks, noises, or performance issues. Use a diagnostic scanner to confirm proper operation.
Common Mistakes to Avoid
Incorrect ring orientation can lead to oil consumption or blow-by.
Over–– or under-torquing bolts, risking damage to the connecting rod.
Skipping cylinder inspection may cause premature piston wear.

Maintenance Tips for OEM OM471 Piston Parts
Regular maintenance extends the life of your OM471 piston parts, reduces downtime, and maintains performance. Here’s a comprehensive maintenance checklist:
Regular Inspections
Check for signs of piston wear, such as:
- Unusual engine noises (e.g., knocking).
- Reduced power or fuel efficiency.
- Increased oil consumption or exhaust smoke.
Use diagnostic tools to monitor piston and ring performance.
Oil Changes
The OM471 uses low-viscosity oil with an electronically controlled oil pressure valve to minimize friction. Change oil every 60,000–100,000 km (depending on usage) using Mercedes-Benz-approved oils. Volgen Power stocks compatible oil filters and lubricants.
Monitor AdBlue and Exhaust Systems
The OM471’s exhaust aftertreatment system relies on AdBlue for NOx reduction. Low AdBlue levels or faulty sensors can increase backpressure, straining pistons. Check AdBlue levels monthly and inspect sensors during routine maintenance.
Coolant System Maintenance
The OM471 uses a coolant pressure control sensor to manage engine temperature. Ensure coolant levels are adequate and replace coolant per Mercedes-Benz’s schedule (typically every 2–3 years).
Fuel System Care
Clogged or faulty fuel injectors can disrupt combustion, affecting piston performance. Clean or replace injectors as needed, and use high-quality diesel fuel to prevent carbon buildup.
Professional Servicing
Schedule regular maintenance with a certified Mercedes-Benz technician. Volgen Power provides maintenance guides and OEM parts to support these efforts.
