KOMATSU excavator pc300 swing pump

The swing pump of the Komatsu PC300-7 excavator is a precision hydraulic unit responsible for supplying oil to the swing motor of the upper structure. This pump is a gear-type design with a volumetric capacity of approximately 45 to 55 liters per minute and an operating pressure of 280 bar. The housing is made of alloy steel with a hardness of 210 to 230 Brinell, ensuring excellent wear and fatigue resistance. Its drive shaft is supported by rolling bearings with a diameter of 45 millimeters for stability and durability.

In terms of type, the Komatsu PC300-7 swing pump operates as an internal gear hydraulic unit that directs oil into the swing motor circuit through the rotation of its driving gear. Heat-resistant O-rings capable of withstanding up to 120 degrees Celsius prevent leakage under high pressure. The pump achieves a volumetric efficiency greater than 92 percent under standard conditions, which ensures smooth and precise swing system performance during heavy-duty excavation tasks.

The repair process of the swing pump involves complete disassembly of the housing, inspection of the gears for wear or micro-cracks, and measurement of radial clearance with a feeler gauge. If the clearance exceeds 0.08 millimeters, gear replacement becomes necessary. Bearings and seals m

KOMATSU excavator separator filter

KOMATSU excavator is among the most well-known manufacturers of excavators in the world that have high performance and durability. separator filters that are used on KOMATSU excavators help eliminate not only solid particles from the fuel which is gas-oil for most heavy duty machines but also removes liquid drops of water, oil and ..
by removing the liquid drips that is absobed first and stored on the top head cap of the separator filter that can later be discharged, separator filters help KOMATSU excavators have better combustion within the engine and have higher external torque. there are various manufacturers of KOMATSU excavator fuel separator filter including international brands such as FLEETGUARD, DONALDSON, MANN, SAKURA , ...
