Frequently Asked Questions
Q1: What is the service life of a Cat OEM hydraulic pump under normal conditions?
A: Under proper maintenance and operation, Cat OEM pumps typically last 8,000-12,000 operating hours.
Q2: What is the replacement part number for Cat pump 487-6207?
A: The direct replacement part number for 487-6207 is CA4876207, an upgraded remanufactured version.
Q3: How to prevent hydraulic pump contamination?
A: Keep hydraulic oil tanks sealed, replace filters regularly, clean the oil fill cap before refueling, and avoid using contaminated tools during maintenance.
Q4: What is the rated displacement of Cat pump 369-9655?
A: The 369-9655 axial piston pump has a displacement of approximately 280 cc/r, suitable for large excavators like 374F/390F.
Q5: Can cold weather affect Cat hydraulic pump performance?
A: Yes, cold temperatures increase oil viscosity, leading to poor lubrication, reduced flow rate, and increased pump startup load.
