CENTER JOINT COVER
The center joint cover on a Komatsu PC200-7 excavator serves as a protective and structural component located over the center joint (also called the swivel joint or rotary manifold), which allows hydraulic fluid to pass between the upper and lower parts of the machine while the upper structure rotates. The center joint cover has several […]
FILTER REGULATOR KOMATSU
When you mention a Komatsu filter regulator, I’ll interpret that as a hydraulic filter, since most excavator systems don’t combine filtering and pressure regulation in one single part—but rather use separate filter elements and valves/regulators. Based on typical Komatsu excavator setups, here are five key functions of the hydraulic filter: 1. Remove Foreign Particles from […]
PC35MR-2 PUMP GEAR
The gear pump in a Komatsu PC35MR‑2 excavator (often functioning as the pilot or auxiliary pump) plays a critical role within the hydraulic system. It’s distinct from the main variable‑displacement piston pump, but it’s essential for supporting overall performance. Here are five key functions of this gear pump: 1. Generates Hydraulic Pressure for Pilot Circuits […]
PC200-5 SWING DEVICE OIL SEAL COVER
The swing device oil seal cover on a Komatsu PC200-5 excavator plays a vital role in protecting and maintaining the integrity of the swing machinery system. Here are five key functions of the oil seal cover: 1. Protects Internal Components 2. Retains Lubricating Oil 3. Supports Oil Seal Positioning 4. Enhances Component Longevity 5. Prevents […]
ENGINE VALVE COVER
