Mini Excavator hydraulic K3V63DT K3V180DT K3V280DT repair kits kawasaki Komatsu K5V80 K5V200 Excavator hydraulic piston pump Assembly parts

The Kawasaki K3V series plunger pump is an open hydraulic pump, mainly composed of a rotary body and control components. The structural components include a housing oil distribution plate, a swing assembly, and a servo mechanism. The inner liner of the Kawasaki K3V series plunger pump adopts modern advanced surface wear-resistant coating technology, which greatly improves the service life of the pump. Featuring advanced performance, reliable operation, and convenient maintenance, it is widely used in various construction machinery. 

Currently, Japanese brands such as "Kobe Steel", "Sumitomo", and "Kato" all use the Kawasaki K3V series plunger pump for excavators. The designed service life of the pump variable mechanism is 10000 hours. However, when the metal particles in the hydraulic oil seriously exceed the standard, the oil in the internal parts of the pump variable mechanism will be washed and worn, causing the clearance between the variable piston and the valve stem and the hole to increase. The servo pressure oil will leak into the pump casing from the clearance between the valve stem and the hole. When the leakage inside the variable mechanism is severe, Without reaching the standard servo pressure oil, it is impossible to push the variable shift lever to the predetermined position, resulting in a decrease in the total output power of the pump. When repairing the pump, attention is often only paid to repairing or replacing the internal components of the pump, without paying attention to checking the internal leakage of the pump's variable mechanism. This way, the repaired pump is usually twice as efficient, and even after installation and use, it still cannot achieve the desired calibration results. The common models of Kawasaki K3V series plunger pumps include: Kawasaki K3VG plunger pump, Kawasaki K3VGSB plunger pump, Kawasaki K3VGTB plunger pump, Kawasaki K3VLSB plunger pump, Kawasaki K3VLTB plunger pump, and Kawasaki K3VL plunger pump.
