1. Why is the CAT 320B excavator engine speed stuck or hunting?
This is commonly caused by a faulty throttle motor like the 7Y-3913X. Internal gear wear or sensor failure prevents the motor from holding the correct position. Replacing with a new 4I-5496 unit usually restores smooth RPM control.
2. How to identify if I need part number 247-5227 or 7Y-3913X?
Check the connector pin count and the cable length. 247-5227 is frequently found in 320C models, while 7Y-3913X and 4I-5496 are standard for 320B. Verify the part number stamped on your old motor or contact our team for a serial number check.
Why Choose This Throttle Motor?
Answer: Our units utilize an OEM-standard tri-metal structure for the internal bushings and are trusted by repair shops and equipment fleets globally for their long-term stability under harsh construction environments.
