FAQ
Q1: How do I confirm this sensor fits my specific Caterpillar 320C excavator? A: First, locate your existing sensor and check the part number stamped on it. If it reads 5i7579, 125-2966, or 196-7973, this is a direct match. If the number is different, please contact our support team with your engine serial number (e.g., from the engine data plate) for verification. While the listed engine models are common applications, variations exist between different years and machine configurations.
Q2: What are the symptoms of a failing revolution speed sensor? A: Common symptoms include: the engine cranking but not starting, sudden stalling while running, erratic RPM readings on the dashboard, a check engine light, or a noticeable loss of power. The engine may also run roughly or misfire. If you experience any of these, testing or replacing the speed sensor is a recommended first step before investigating more complex issues.
Q3: Is installation straightforward, and what tools are required? A: Installation is generally straightforward for a qualified mechanic. The sensor is typically located on the engine block near the flywheel or crankshaft pulley. You will likely need a socket set and possibly a Torx bit to remove the retaining bolt. It is crucial to clean the mounting area and ensure the sensor gap is set correctly (usually a non-contact air gap of 0.5-1.5mm, but always consult your machine’s service manual for the exact specification). We recommend using a thread locker on the retaining bolt to prevent loosening due to vibration.
