Quick Answer The Komatsu PC210-8K hydraulic pump (reference part numbers 708-2L-00701 / 708-2L-00700 / 708-2L-01701 / 708-2L-01700) is the main pump assembly for the 21-ton-class PC210-8K excavator. RITO HYDRAULIC supplies this complete assembly — net weight 162 kg — with OEM-parameter fit for easy installation and high replacement precision. Key characteristics: responsive electronic ...

Quick Answer The Kawasaki K3V180DTP is a tandem variable-displacement axial piston pump built for the Hyundai R340 and R340L (30–40 ton class). It uses a twin-plunger structure for stable high-pressure output under heavy load, a precision valve plate and wear-resistant plunger assembly for long service life, and the original OEM interface for direct replacement. Reference part number 31N9-10...

Quick Answer The Komatsu PC210-7K (20-ton class) runs the main pump referenced as 708-2L-00202 (alternates: 708-2L-00200, 708-2L-00203), net weight about 181.6 kg. It uses a variable plunger, load-sensing structure for precise control and strong digging power. This guide helps you answer the real question: is the pump actually failing, or is something else in the circuit? — then how to confi...

Quick Answer An excavator's hydraulic system turns the engine's rotating power into force and motion using pressurised oil. The main pump pushes oil; the control valve directs it to the right function; cylinders create straight-line force (boom, arm, bucket) and motors create rotation (swing and travel). Oil then returns to the tank and through the filters. Understanding this loop explains why the...

Quick Answer The control valve assembly is the "brain" of an excavator: it directs the pump's oil to every function. You must replace it when the body or bore is damaged, when a spool sticks or leaks internally beyond repair, when metal contamination has scored the valve, or when the valve has been rebuilt once already and failed again. You choose the right model by matching six points: machine mo...

Quick Answer The Kobelco SK200 / SK210 / SK220 / SK250 / SK260 excavators — the whole -8 generation plus the SK210-9 — share one family of main control valve assemblies, commonly ordered under two numbers: YN30V00101F5 and YN30V00126F1. They are the same family, but "same family" does not mean freely interchangeable: the suffix and build level decide which machine each number belongs t...

Quick Answer This page is a quick reference for the main hydraulic pump assembly on the Komatsu PC200-7 and PC220LC-7 excavators. The assembly is a twin (tandem) variable-displacement axial-piston pump — two pumping sections in one housing — ordered under 708-2L-31123 or 708-2L-00300. It weighs about 195 kg and ships in a 53 × 53 × 81 cm case. Use the tables below to identi...

Quick Answer The main pump is the heart of a Komatsu PC200-8 excavator. It takes mechanical power from the engine and turns it into hydraulic power — pressurised oil flow — that moves every boom, arm, bucket, swing and travel function. The PC200-8 uses a variable-displacement piston pump: instead of always pumping the same amount, it continuously changes its output to match what the op...
