Whether you are rebuilding a generator set in North America or overhauling a bulldozer in the Middle East, this bearing set provides the dimensional accuracy and material integrity required for a successful engine rebuild.

Key Features & Benefits

• OEM-Grade Fitment: Produced as a direct cross-reference for Cummins part numbers 3801260 (main/con rod) and 214950 (thrust washer), guaranteeing proper clearance and load distribution.
• Proven Material Technology: Mahle utilizes high-strength aluminum alloy or tri-metal steel backing (depending on specific variant) for superior fatigue resistance and load-carrying capacity.
• Complete Set Convenience: Includes all necessary main bearings, connecting rod bearings, and the thrust washer in one package, simplifying procurement and reducing sourcing errors.
• Global Standard Quality: Manufactured in Mahle-licensed facilities with 100% new condition, meeting international quality benchmarks for heavy-duty diesel applications.
• Enhanced Durability: Engineered to withstand the high cylinder pressures and thermal stresses common in turbocharged NT855 engines, extending overhaul intervals.
• Reduced Downtime: Precision machining eliminates the need for selective fitting in most standard applications, accelerating the engine assembly process.
• Corrosion Protection: Oil film retention and anti-corrosion coatings protect the bearing surfaces during initial start-up and storage.

FAQ

Q1: How do I verify that this bearing set fits my specific NT855 engine?
A: First, check the stamped part numbers on your old bearings. Look for “3801260” on the main and rod bearings, and “214950” on the thrust washer. This set is a direct replacement for those numbers. If your engine uses a different suffix (e.g., 3801260-01), it is likely the same dimension but verify the width and thickness against a micrometer. For non-standard applications (e.g., engines with oversized crankshafts), you may require a specific undersize bearing.

Q2: Do I need to replace the thrust washer at the same time as the main bearings?
A: Yes, it is highly recommended. The thrust washer controls the crankshaft’s end-play. Even if the old washer appears serviceable, the new main bearings will alter the crankshaft’s axial position slightly. Installing a new thrust washer (214950) ensures correct end-play is maintained, preventing premature bearing and crankshaft thrust face wear.

Q3: What installation precautions should I take with these Mahle bearings?
A: Ensure all bearing bores and the crankshaft journals are perfectly clean and free of burrs. Lubricate the bearing surfaces with clean engine assembly lube or 30-weight oil during installation. Do not file, scrape, or sand the bearing backs. When torquing the main bearing caps, follow the Cummins NT855 service manual procedure (typically a multi-step torque sequence to specified ft-lbs). Always check bearing clearance with Plastigauge on at least the first and last main bearing to confirm proper oil clearance.
