The Swash Plate is the central control element inside the variable displacement K3V112DTP pump. Its angled surface determines the stroke length of the piston assembly, directly controlling the volume of hydraulic oil the pump delivers. Over time, the high-pressure sliding contact between the piston shoes and the swash plate surface leads to wear, grooves, and loss of precision. This causes internal leakage, reduced pump volumetric efficiency, and ultimately, weak machine performance. Our replacement swash plate is precision-machined from high-grade materials and hardened to restore the original angle and mirror-smooth surface finish, ensuring optimal pump control and efficiency.

Key Features & Benefits

• Precision Engineered for K3V112DTP: Guaranteed compatibility and performance for the K3V112DTP hydraulic pump used in the Kobelco SK200-8 excavator.

• Restores Full Hydraulic Power & Speed: A new, precisely angled swash plate eliminates internal slippage, restoring pump output to factory specifications for strong, responsive digging and fast cycle times.

• Superior Durability & Surface Finish: Manufactured from high-strength alloy steel and treated with advanced surface hardening (e.g., nitriding) to resist wear and grooving, ensuring a long service life.

• Optimized for Efficiency: The ultra-smooth, precisely ground contact surface minimizes friction and heat generation, improving overall hydraulic system efficiency and reducing fuel consumption.

• Critical for Complete Pump Overhaul: This part is essential for any serious rebuild of the K3V112DTP pump. It is highly recommended to replace it alongside the piston/cylinder assembly (rotating group) and valve plate for a balanced repair.

• Cost-Effective Pump Restoration: Replacing the worn swash plate is a far more economical solution than purchasing a complete new or remanufactured pump, saving thousands in parts and downtime.

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a worn swash plate in my K3V112DTP pump?
A: Key indicators include:

• A significant, gradual loss of overall hydraulic power and digging force.

• Slow cylinder movement and sluggish machine operation.

• The engine does not lug down under heavy load (a sign of pump slipping internally).

• Increased hydraulic system noise and overheating.

Q2: Is this swash plate sold individually or as part of a kit?
A: This listing is for the Swash Plate as an individual component. For a complete and reliable rebuild, we strongly recommend purchasing it as part of a K3V112DTP Repair Kit that includes the matching piston/cylinder assembly, valve plate, and seals.

Q3: Can I install this swash plate myself?
A: No. Replacing the swash plate requires a complete, professional-level teardown and rebuild of the K3V112DTP hydraulic pump. This demands a cleanroom environment, specialized tools, and expert knowledge. Installation must be performed by a qualified hydraulic pump technician.

Q4: Why should I replace the swash plate and not just the piston kit?
A: The piston shoes and swash plate wear together as a matched pair. Installing new pistons against a worn plate will lead to rapid, premature failure of the new parts. For a lasting repair, both must be replaced simultaneously.

Q5: Is this an OEM part?
A: This is a high-precision, aftermarket replacement part manufactured to meet or exceed the original OEM specifications for material, hardness, and dimensions for the K3V112DTP pump.
