Good To Know
Q: How do I know this sensor fits my excavator? A: This sensor is designed for the listed for Caterpillar D-series models, but always verify your machine's serial number and existing part number 434-3436 before ordering to confirm compatibility.
Q: What are common signs of a failing sensor? A: Common symptoms include erratic hydraulic performance, error codes on the display, or pressure readings that seem inaccurate, which can indicate a faulty sensor that should be replaced promptly.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
