Frequently Asked Questions (FAQ)
Q: Is this engine oil pump a genuine Caterpillar part?
A: This is a premium-grade, OEM-compatible aftermarket replacement oil pump. It is engineered to exact CAT dimensional and technical standards, serving as a direct drop-in replacement for part number 4N-4864 / 4N4864.
Q: My equipment engine is showing low oil pressure warnings. Is replacing the 4N-4864 oil pump necessary?
A: Low oil pressure is often caused by internal gear wear or housing clearance degradation within the oil pump. Replacing your worn pump with this new 4N4864 oil pump restores proper oil flow and pressure, protecting your engine against catastrophic bearing and crankshaft damage.
