[email protected]Part Number: 381-2499 (3812499)
Precision-engineered for CATERPILLAR C6.6 engines.
Ensures stable electrical signal transmission to fuel injectors, vital for combustion.
Constructed with durable high-temperature insulation materials for engine bay resilience.
Direct fitment replacement for OEM 381-2499.
Effectively resolves intermittent misfire and harness failure issues in C6.6 machinery.
Part Number: 7861-92-4800 (7861924800)
Provides high-accuracy liquid level detection for Komatsu excavators.
Designed for use as a reliable fuel or hydraulic tank sensor.
Features reliable sealing against contaminants and harsh operating conditions.
Critical component for protecting KOMATSU 7861-92-4800 system components from low fluid levels.
Easy replacement ensures proper monitoring functionality on your Komatsu machine.
Fault Example:
A Komatsu PC200-8 Excavator Engine (6D107E-1) suddenly experiences power loss or stalls intermittently.
Potential Cause & Solution:
A common culprit is a damaged or aged Injector Wiring Harness (like the CATERPILLAR 381-2499 for C6.6 engines). High heat and vibration can cause insulation breakdown, leading to signal loss and misfire. The solution involves checking the electrical continuity of the harness and ensuring proper routing away from heat sources.
General Maintenance:
Perform routine engine oil analysis and replace fuel pre-filter and main filter every 500 working hours to protect the delicate Fuel Injector and Diesel Fuel Pump components.
