Claim 11:
12. The method of claim 10, wherein the hydraulic fracturing pump comprises a drive assembly including the crankshaft and at least one planetary gearbox arranged at an end of the corresponding opposite ends of the hydraulic fracturing pump, and driving the opposite ends of the crankshaft includes:
rotating a sun gear of the planetary gearbox coupled to a first one of the opposite ends of the crankshaft, the rotation of the sun gear being translated to a ring gear by a plurality of planetary gears arranged between the sun gear and the ring gear;
driving a first pinion gear with the rotation of the ring gear, the first pinion gear engaged with a connector shaft at a first end thereof, the connector shaft positioned substantially parallel to the longitudinal axis of the crankshaft and circumferentially positioned between a first plane in which the corresponding first plunger of each of the plurality of plunger pairs reciprocates and a second plane in which the corresponding second plunger of each of the plurality of plunger pairs reciprocates, wherein the first plane and the second plane are angularly offset by a non-zero angle about the longitudinal axis; and
driving a second pinion gear engaged with the connector shaft at a second end thereof, the second pinion gear configured to engage with and drive rotation of the crankshaft from a second one of the opposite ends of the crankshaft.
