Caterpillar original Fuel Injector 140-8413 1408413 0R8867 OR-8867 Replacement for OEM 3114 3116 3126 Diesel Engine Wheel Loader Excavator Bulldozer original new injector

The Caterpillar 140-8413 Fuel Injector is an industrial-grade diesel injection component engineered for the CAT 3116 Series engine, with related compatibility across CAT 3114 and CAT 3126 applications. It is widely used on CAT 938G Wheel Loaders, IT38G units, and other Caterpillar engine-powered construction machinery, industrial diesel engines, trucks, generator sets, and marine auxiliary equipment. The injector is cross-referenced with 1408413, 0R-8867, 0R8867, OR-8867, OR8867, 127-8220, 7E-6193, 7E6193, 9Y-4982, 9Y4982, and 127-8230, supporting distributor inventory, export spare parts supply, and aftermarket replacement sales.

Manufactured to OE-style fitment standards, this injector assembly delivers metered fuel into the combustion chamber at the correct timing, ensuring stable atomization and strong sealing performance. It helps maintain stable idle, strong torque output, cleaner combustion, easier starting, lower exhaust smoke, and reliable overall engine performance. The heavy-duty construction supports individual replacement, full engine set replacement, diesel engine rebuilding, fleet maintenance, and diesel repair shop operations, making it suitable for both single-unit service and wholesale distribution.

To maximize service life, operators should focus on fuel cleanliness, timely filter replacement, water separation, and fuel tank condition. Dirty filters, water contamination, or rusty tanks can shorten injector life. Sealing rings should be replaced during installation, and torque values must follow the official Caterpillar service manual. After installation, inspect for leakage, idle stability, smoke output, misfire, and load performance. In severe cases of rough running, cylinder imbalance, or power loss, testing or replacing the full injector set is recommended to restore balanced engine operation.
