Sany Original Hydraulic Pump and Engine Flange Coupling CF-K-150-D-11-11561, Sany Material Code: 60265367

Sany Original Hydraulic Pump and Engine Flange Coupler CF-K-150-D-11-11561, Sany Material Code: 60265367
Core Information
- Model: CF-K-150-D-11-11561 (CENTAFLEX-K-150)
- Sany Material Number: 60265367
- Compatible Models: Sany SY305/SY335/SY365/SY375 and other excavators equipped with Isuzu 6HK1 engine + main hydraulic pump
- Structural Form: High Elasticity Flange Coupler (CENTAFLEX-K Series), with rubber vibration-damping disc + splined sleeve
- Functions:
1. Power Transmission: Connects the engine flywheel to the hydraulic pump input shaft to transmit torque
2. Vibration Damping and Shock Absorption: Absorbs engine torsional vibrations, protects the hydraulic pump, and prevents resonance damage
3. Misalignment Compensation: Allows minor axial/radial/angular installation misalignment, reducing assembly requirements
Key Parameters
- Rated Torque: 1200 N·m
- Maximum Torque: 3000 N·m
- Maximum Speed: 4000 rpm
- Flange Specification: SAE 11-1/2" Standard Flange
- Spline Parameters: 16 teeth/19 teeth, compatible with Kawasaki K5V/K7V series main pumps
- Material: High-strength fiberglass-reinforced plastic + high-quality rubber vibration-damping layer, corrosion-resistant and aging-resistant
- Operating Temperature: -40℃ ~ +95℃, suitable for harsh engineering machinery conditions
Purchase and Installation Notes
- Code Verification: Confirm CF-K-150-D-11-11561 + 60265367, distinguish flange specifications and spline tooth counts to avoid mixing with CF-K-100/200 and other models
- Replacement Timing: Replace when rubber disc cracks/delaminates, coupler makes abnormal noise/vibrates, hydraulic pump input shaft spline wears, or power transmission slips
- Installation Focus:
1. Axial alignment error between engine and hydraulic pump ≤ 0.1mm to avoid uneven loading
2. Tighten flange bolts diagonally in stages, torque 80–100 N·m, use anti-loosening adhesive
3. Ensure no looseness between splined sleeve and pump shaft; apply a small amount of lubricant if necessary
- Fault Correlation: Hydraulic system noise, excessive pump body vibration, abnormal engine load, fluctuating power output – prioritize checking this coupler
