4326596 3408503 Crankshaft Cam Position Sensor Replacement for Cummins Engine M11 ISM11 QSM11 N14 Excavator Loader 4326595

Product Overview The 4326596 / 3408503 Crankshaft Position Sensor (also functions as a Camshaft Position Sensor depending on application) is a critical diagnostic component designed for Cummins Heavy-Duty Diesel Engines. Mounted near the crankshaft or camshaft gear housing, this high-precision sensor monitors the exact rotational timing and speed of the engine, sending real-time electronic pulse data to the Engine Control Module (ECM). By ensuring accurate fuel injection and ignition synchronization, it prevents engine misfires, hard starting conditions, and sudden stalling, making it an essential maintenance replacement part for high-hour construction machinery and commercial fleets. Technical Specifications Main OE Number: 4326596, 3408503 Interchangeable Numbers: 4326595, 3049092, 3073894, 3078150, 3078151, 3408502, 4984223, 2872362 Aftermarket Reference: PAI 050700, B07A-Cam Crank Sensor Function: Crankshaft / Camshaft Position, Speed & Timing Monitoring Connector Design: Premium Heavy-Duty Weatherproof Sealed Plug with Wiring Harness Material: High-Grade Anti-Magnetic Metal Alloys and Wear-Resistant Engineered Composites Condition: 100% Brand New Premium Aftermarket Replacement Broad Vehicle Compatibility This position sensor features a widespread application footprint, crossing over major Cummins-powered heavy equipment, industrial loaders, crawler excavators, and commercial trucks: Series Compatible Models & Engine Applications Cummins Engine Platforms M11, ISM11, QSM11, N14, Select ISM and QSM Series Heavy-Duty Diesel Engines Construction Machinery Heavy Crawler Excavators, Large Wheel Loaders, and Industrial Power Units (such as Komatsu, Terex, and LiuGong equipment powered by Cummins engines) Commercial Trucks & Fleets Heavy-duty freight trucks, dump trucks, and transit vehicles equipped with Cummins M11/ISM/N14 drivetrains Key Benefits Dual-Position Utility: Highly versatile cross-compatibility allows this part to seamlessly serve as either a crankshaft position or a camshaft position reference sensor depending on the specific Cummins ECM layout. High Thermal Stability: Engineered with a premium ruggedized housing to withstand prolonged exposure to intense engine block heat, harsh engine oils, and severe off-road vibrations. Precision Signal Tracking: Effectively eliminates common electronic timing faults, erratic idling, and “Check Engine” dashboard codes, preventing forced limp-mode states. Easy Installation: Built to exact OEM dimensional specifications (4326596 / 3408503) for a tight, leak-proof, plug-and-play fit without cutting or splicing the harness. Cross-Reference Guide This sensor interchanges with the following original and aftermarket part numbers: CUMMINS: 4326596, 3408503, 4326595, 3049092, 3073894, 3078150, 3078151, 3408502, 4984223, 2872362 PAI / AFTERMARKET: PAI 050700, Premium heavy-duty electrical components calibrated to factory diagnostic parameters Maintenance Tip: If your Cummins QSM11 or M11 Engine experiences extended cranking before starting, intermittent stalling while hot, or throws active timing codes, inspect the 4326596 sensor plug. Because it reads gear tooth rotations, the magnetic pick-up head frequently collects fine metallic dust over time. We highly recommend pulling the sensor, wiping the inductive face completely clean, and checking the plug pins for oil intrusion before installing this new replacement unit.
