Precision Components for Kubota Z600 & D850 Diesel Engines

Ensure maximum compression and longevity for your Kubota Z600 or Kubota D850 engine, commonly found in compact tractors (like the B6200 series) and small excavators (like the KH-35). These engines rely on high-quality internal components for optimal performance. We supply certified parts for a complete rebuild:

• Kubota Z600/D850 Piston: Precision engineered Part Number 15956-21110, also available as 1595621110. This part is crucial for converting combustion energy into mechanical work.

• Kubota Z600/D850 Piston Ring Set: Essential for sealing the combustion chamber, Part Number 15901-21050, and its simplified version 1590121050. These rings prevent oil from entering the combustion chamber and maintain power.

Although the cylinder liner number was not provided, we offer OE-specification Kubota Cylinder Liner sets and complete Kubota D850 Engine Overhaul Kits to cover all your maintenance needs.

10 Engineering Machinery Parts Definitions:

1. Piston Pin Bushing: A sleeve inside the Connecting Rod small end. Isuzu 6HK1 Connecting Rod Piston Pin Bushing – Ensures smooth connection between the piston and rod.

2. Camshaft: Located in the Engine Block/Head. Cummins QSL9 Engine Camshaft Lobe – Controls the opening and closing of the intake and exhaust valves.

3. EGR Cooler: Sits externally, often near the Exhaust Manifold. Caterpillar C15 Engine EGR Cooler Assembly – Cools exhaust gas before recirculation to reduce combustion temperature.

4. Cylinder Head Gasket: Seals the joint between the Cylinder Head and Engine Block. Yanmar 3TNA72 Cylinder Head Gasket Seal – Critical barrier for maintaining combustion pressure and fluid separation.

5. Vibration Damper: Attached to the front of the Crankshaft. Weichai WP12 Engine Harmonic Balancer – Minimizes torsional vibrations from the crankshaft rotation.

6. Oil Cooler: Typically mounted on the Engine Block or Oil Filter Housing. Kubota V2403 Oil Cooler Core – Reduces engine oil temperature for better lubrication.

7. Solenoid Valve: Can be mounted on the Fuel Pump, Starter, or Injection Pump. Komatsu PC78US-6 Engine Fuel Shutoff Solenoid – Controls fuel flow to stop the engine.

8. Thermostat: Located in the Cooling System Housing, usually near the radiator hose connection. Kubota Z600 Engine Coolant Thermostat – Regulates the engine operating temperature.

9. Exhaust Valve: Located in the Cylinder Head. Cummins ISB 6.7 Exhaust Valve Seat – Allows burnt gases to exit the combustion chamber.

10. Bearing Shells (Main/Con Rod): Fit between the Crankshaft/Connecting Rod and their respective housings. Caterpillar 3412 Engine Main Bearing Shells – Reduce friction and support rotating parts.

Troubleshooting Guide: Addressing Engine Malfunctions

Fault: Komatsu PC200-8 Excavator (Engine SAA6D107E-1) Overheating

Fault Detail:

The Komatsu excavator's engine temperature gauge frequently rises into the red zone during heavy operation or long periods of use, and coolant levels drop rapidly. This is a severe problem requiring immediate attention.

Solution/Treatment Plan:

1. Cooling System Integrity: Inspect the Radiator for external clogs and internal blockages. Check all Radiator Hoses for leaks and swelling. Confirm the Komatsu Water Pump is circulating coolant effectively.

2. Thermostat and Fan Check: Test or replace the Thermostat, as a stuck-closed thermostat will prevent cooling. On this model, verify the Fan Clutch/Drive is engaging properly to pull sufficient air across the radiator.

3. Internal Engine Damage: If external checks fail, suspect a Cylinder Head Gasket failure. A failed gasket allows combustion gases to pressurize the cooling system, leading to rapid coolant loss and overheating. A coolant pressure test is required to confirm this. The engine may require a complete Engine Overhaul Kit for repair.
