KAWASAKI hydraulic pumps are widely used in concrete pump trucks, excavators, and other heavy machinery due to their reliable performance and durable design. The K3V and K5V series are two of the most commonly used pump families, with displacements ranging from 63cc to 200cc. Correctly matching the internal components is crucial for stable operation and long service life.

Key Principles for Spare Part Matching:

1. Identify the Pump Model and Displacement Size
   For example: K3V112 = 112cc displacement, K5V200 = 200cc. Their parts differ in size and design.

2. Cross-verify OEM Numbers or Drawings
   Quality suppliers typically provide one-to-one matching based on OEM part numbers, ensuring exact fit for sealing surfaces, threads, tolerances, and overall structure.

3. Replace Complete Component Sets Together
   This includes: piston & shoe assemblies, valve plates, cylinder blocks, drive shafts, support blocks, springs, and ball guides. Avoid mixing old and new parts, which can cause internal noise or misalignment.

4. Check for Small Variations Based on OEM Brand
   Even for the same model (e.g., K5V200), minor design differences (like spline shapes or flange positions) may exist across different equipment brands (CAT, SANY, XCMG). Always confirm with your supplier.
