Optimized Compatibility: Designed specifically for Caterpillar 3116 and Komatsu 6D102 series to eliminate dashboard error signals.
Heavy Duty Durability: The 7861-92-4800 signal lamp is built to withstand high-vibration excavator environments.
Precision Sensing: Komatsu Float Switch ensures accurate fluid level monitoring to prevent engine overheating or dry running.
High-Quality Replacement: Cost-effective domestic alternative to expensive original parts without compromising on service life.
Easy Installation: Plug-and-play design compatible with standard Caterpillar wiring harnesses and Komatsu monitor systems.
Turbocharger: Found in Cummins QSB6.7 engines; enhances power output. Example: Cummins QSB6.7 Turbocharger.
Fuel Injector: Installed in Isuzu 4HK1 cylinder heads; atomizes fuel for combustion. Example: Isuzu 4HK1 Fuel Injector.
Water Pump: Attached to Caterpillar C7 engine blocks; circulates coolant. Example: Caterpillar C7 Water Pump.
Cylinder Head Gasket: Placed between block and head on Yanmar 4TNV98. Example: Yanmar 4TNV98 Gasket Head.
Piston Ring Set: Located on pistons in Komatsu 6D107. Example: Komatsu 6D107 Piston Ring.
Main Bearing: Supports the crankshaft in Weichai WD615. Example: Weichai WD615 Main Bearing.
Oil Pump: Lubricates moving parts in Kubota V2403. Example: Kubota V2403 Oil Pump.
Solenoid Valve: Controls fuel shut-off in Caterpillar 320D. Example: Caterpillar 320D Flameout Solenoid.
Radiator: Front-mounted cooling unit for Komatsu PC200. Example: Komatsu PC200 Radiator.
Accelerator Motor: Controls throttle on Isuzu-powered excavators. Example: Isuzu 4JJ1 Accelerator Motor.
Diagnosis: Often caused by a faulty 7861-92-4800 (7861924800) sensor or damaged wiring. If the red signal lamp persists despite normal fluid levels, the float switch may be grounded.
Solution: Replace the signal lamp and inspect the connector for corrosion. For long-term maintenance of your Caterpillar 3116 engine, ensure the overhaul gasket kit is checked every 5000 hours to prevent leaks that can damage electrical sensors.
