116-6680 Engine Revolution Speed Sensor Replacement for Caterpillar CAT Excavator M312 M315 Loader 924G Truck 793F 797 1166680 T115148

Product Overview The 116-6680 Engine Revolution Speed Sensor is a critical diagnostic and timing component designed for Caterpillar (CAT) Industrial Machinery and Diesel Engines. This premium inductive sensor is engineered to monitor engine rotational speed (RPM) and cam/crankshaft position, sending precision electronic pulses to the vehicle’s Electronic Control Module (ECM). By providing real-time timing tracking, it prevents erratic gear shifting, engine sputtering, and throttle synchronization failures, making it an essential high-quality replacement part for high-hour commercial equipment and heavy construction fleets. Technical Specifications Main OE Number: 116-6680, 1166680 Interchangeable Numbers: T115148, T115148-00 Function: Engine RPM / Revolution Speed and Timing Monitoring Connector Type: Factory-Spec Heavy-Duty Waterproof Sealed Plug Material: High-Strength Anti-Magnetic Metal Housing and Heat-Resistant Internals Condition: 100% Brand New Premium Aftermarket Replacement Broad Vehicle Compatibility This heavy-duty speed revolution sensor is highly versatile and compatible with standard Caterpillar C4, C6, and C7 diesel engine platforms across the following application series: Series Compatible Models & Engine Applications CAT Wheeled Excavators M312, M315, M315B Series Wheeled Machinery CAT Wheel Loaders & Tool Carriers 914G, 924G, 924GZ Integrated Tool Carriers CAT Off-Highway Mining Trucks 793F, 797, 797B, 797F Ultra-Class Mining Trucks Engine Platforms Caterpillar C4, C6, C7, 3054, and 3126 Industrial Diesel Engines Key Benefits Multi-System Utility: Seamlessly interchanges with factory number T115148, functioning perfectly as either a primary governor reference or transmission gear-speed pickup. High Thermal Stability: Built with a premium ruggedized chassis to withstand prolonged exposure to intense engine block heat, engine oils, and severe off-road job site vibrations. Precision Accuracy: Resolves common dashboard issues like “RPM Gauge Needle Jumping,” preventing the excavator or loader from forcing itself into limp-safe power mode. Easy Installation: Exact direct-fit profile matches OEM specifications (116-6680) for a tight, clip-on plug-and-play installation without wire splicing. Cross-Reference Guide This sensor interchanges with the following original and aftermarket part numbers: CATERPILLAR: 116-6680, 1166680 PERKINS / OTHERS: T115148, Heavy-duty commercial electrical accessories calibrated to original CAT diagnostic parameters Maintenance Tip: If your CAT M315 Excavator or 924G Loader experiences rough idling, sudden engine cutting out under hydraulic load, or fails to communicate engine speed to the monitor panel, inspect the 116-6680 sensor head. Because it sits near rotating engine gears, the magnetic pick-up tip easily collects fine metallic dust over months of heavy duty use. We highly recommend pulling the sensor, wiping the inductive face completely clean, and checking the wiring harness plug for any oil intrusion before installing this new unit.
