FAQ

Q: How do I confirm this injector will fit my specific Weichai engine?
A: The most reliable method is to match the part number. Locate the number stamped on the body of your current injector (e.g., K4100, WC495) and verify it matches one of the numbers listed in our OEM Cross-Reference section. Providing your engine model and serial number can also help us confirm compatibility.

Q: Are these injectors sold individually or as a set?
A> They are typically sold as individual units, allowing you to replace only the faulty injector(s). However, we offer competitive pricing for full engine sets (e.g., 6 units for a 6-cylinder engine). Please inquire for set pricing.

Q: What precautions should be taken during installation?
A> Proper installation is critical. Always use new sealing washers or O-rings. Ensure the injector bore in the cylinder head is clean. Tighten to the manufacturer’s specified torque using a calibrated torque wrench to avoid damage. It is highly recommended that installation be performed by a qualified technician familiar with diesel fuel systems.
