4326596 3408503 Crankshaft Cam Position Sensor Replacement for Cummins Engine M11 ISM11 QSM11 N14 2872362 4984223

Product Overview The 4326596 / 3408503 Crankshaft Position Sensor (also widely designated as a Camshaft Position Sensor or Krukas Positie Sensor) is a high-precision diagnostic timing component engineered explicitly for Cummins Heavy-Duty Diesel Engines. Positioned adjacent to the crankshaft flywheel ring gear or camshaft gear lobe, this inductive electromagnetic sensor continuously tracks real-time rotational speed (RPM) and top-dead-center (TDC) timing. It feeds stable digital wave pulses straight to the Engine Control Module (ECM) to regulate flawless fuel injection cycles and optimal engine timing, making it an indispensable maintenance replacement part for global heavy equipment, generator sets, and line-haul commercial fleets. Technical Specifications Main OE Reference Numbers: 4326596, 3408503 Interchangeable Numbers: 2872362, 4984223, 3078151, 3073895, 3049093, 3049092, 3073894, 3078150, 3408502, 4326595 Aftermarket Industry Reference: PAI 050700, B07A-Cam Crank Positioning Module Function: Crankshaft / Camshaft Rotational Position, Engine Speed, and Ignition Timing Synchronization Connector Design: Heavy-Duty Sealed Weatherproof Multi-Pin Plug with Anti-Chafe Wiring Tail Material: Premium Anti-Magnetic Stainless Steel Shell and High-Heat Resistance Internal Coils Condition: 100% Brand New Premium Aftermarket Replacement Broad Vehicle Compatibility This premium position timing sensor boasts an extensive global footprint, primarily crossing over between standard Cummins-powered heavy industrial machinery, marine power blocks, and global commercial truck drivetrains: Engine Platform Compatible Heavy Machinery & Commercial Applications Cummins M11 / ISM11 Series Heavy-duty dump trucks, regional transit buses, and freight haulers (e.g., Freightliner, International, Kenworth fleets using ISM/M11 platforms) Cummins QSM11 Industrial Heavy crawler excavators, mega wheel loaders, rock crushers, and container handlers (such as Komatsu, Terex, LiuGong, and Sany heavy machinery) Cummins N14 Legendary Block Classic commercial highway semi-trucks, high-output industrial water pumps, and heavy mining support machinery Power Generation & Marine Compatible with heavy-duty commercial marine diesel gen-sets and emergency standby power units utilizing 3408503 / 4326596 diagnostic monitoring loops Key Benefits Dual-System Utility Calibration: High versatility cross-engineering allows this exact unit to function flawlessly as either a crankshaft position sensor or a camshaft timing pickup based on native Cummins engine wire layouts. Elite Thermal & Fluid Stability: Ruggedized potting and premium outer shielding protect the internal magnetic pickups from simmering engine oil mist, aggressive diesel grime, and severe off-road vibration cycles. Precision Synchronization: Eradicates typical high-hour engine faults such as erratic idling, sudden dropping of the RPM gauge needle, white smoke emissions during cold-cranking, or active timing codes. Drop-In Installation: Manufactured to exact original factory structural standards for a tight, leak-proof, thread-in fitment, keeping the perfect clearance gap with internal gears. Cross-Reference Guide This sensor interchanges with the following original and aftermarket part numbers: CUMMINS: 4326596, 3408503, 2872362, 4984223, 3078151, 3073895, 3049093, 3049092, 3073894, 3078150, 3408502, 4326595 PAI / AFTERMARKET: PAI 050700, Premium heavy-duty industrial electronics calibrated to match factory diagnostic parameters Maintenance Tip: If your Cummins QSM11 Excavator or ISM11 Truck Engine experiences extended cranking cycles before catching, intermittent stalling when reaching peak operating temperatures, or triggers active diagnostic codes, check the 4326596 sensor plug. Since it relies on magnetic induction over moving gear teeth, fine metallic filings frequently accumulate on the sensor face over long operation cycles. We highly recommend unscrewing the sensor, wiping the inductive tip perfectly clean of any metallic dust, and verifying that no engine oil has seeped into the multi-pin connector plug before sealing this new replacement unit.
