Q: What Komatsu models use the 6741-81-9220 and 7861-93-4210 sensor kit?
A: The COGENG OEM-compatible engine oil pressure and level sensor kit is a direct replacement for Komatsu part numbers 6741-81-9220 and 7861-93-4210, designed for various Komatsu excavators, dozers, wheel loaders, and other heavy equipment models where these sensor part numbers are specified. Always verify both part numbers against your machine's parts manual or the original sensors' identification markings to confirm exact compatibility before ordering.
Q: What are the symptoms of a failing engine oil pressure or oil level sensor on Komatsu equipment?
A: Common symptoms include false low oil pressure warnings, inaccurate or erratic oil pressure gauge readings, false low oil level alarms, the engine control system entering a derate or failsafe mode, diagnostic trouble codes related to the oil pressure or oil level sensor circuits, or failure of the automatic engine shutdown protection to activate during actual low oil pressure conditions. Faulty sensors can lead to unnecessary downtime or, in worst cases, catastrophic engine damage if genuine low oil pressure goes undetected.
Q: What is the difference between the 6741-81-9220 and 7861-93-4210 sensors?
A: The 6741-81-9220 is typically the engine oil pressure sensor, while the 7861-93-4210 is typically the engine oil level sensor. Both sensors work together to provide comprehensive engine lubrication monitoring. The COGENG kit includes both sensors for a complete oil monitoring system replacement, ensuring reliable engine protection.
