NISSAN TB48 BILLET OIL PUMP GEAR

Nissan Patrol TB48 High-Strength Billet Steel Oil Pump Gear Set

The stock sintered metal or powdered-iron oil pump gears in the Nissan Patrol TB48DE engine are notoriously fragile when exposed to high RPM limits, aggressive hard-cut rev limiters, rapid torque spikes, and engine harmonic vibrations. Under heavy drag or dune racing stress, OEM gears shatter—causing instantaneous oil pressure loss, bearing starvation, and catastrophic engine destruction. Installing precision CNC-machined EN26 high-tensile billet steel or MartenWear-treated oil pump gears permanently fortifies the front cover pump housing, providing unbreakable structural integrity, high flow rates, and rock-solid oil pressure across extreme operating conditions.
