222-5967 Fuel Injector FAQ
Q1: What is the exact application of the 222-5967 injector?
A: It is a HEUI (Hydraulic Electronic Unit Injector) specifically designed for Cat 3126B and 3126E diesel engines. It is widely used in medium-duty freight trucks, school buses, motorhomes (RVs), and mili-tary tactical vehicles (such as FMTV/LMTV) manufactured between 1998 and 2004.
Q2: What are the interchangeable part numbers for 222-5967?
A: This injector is fully interchangeable with the following Cat part numbers:
173-9267 (Previous/Old OEM number)
0R-9349 ( Official Remanufactured/Reman number)
Q3: What causes this type of HEUI injector to fail?
A: Because HEUI systems utilize high-pressure engine oil to actuate fuel injection, the most common causes of failure are contaminated engine oil, neglected oil changes, or poor fuel quality. These issues lead to internal O-ring wear and debris buildup, resulting in hard starts (especially when hot), misfires, or rough idling.
Q4: Is a core charge required for this injector?
A: If you are purchasing a genuine Cat Reman (0R-9349), a core deposit is typically required by the dealer until you return your old injector. However, if you are purchasing aftermarket brand-new replacements, no core charge is required.
Q5: Are installation seals/O-rings included?
A: Most reputable suppliers include the external O-rings and the copper crush washer pre-installed on the injector body. It is highly recommended to verify this before purchasing and to pre-lubricate the O-rings with clean engine oil during installation to prevent tearing.
