Frequently Asked Questions
Q: What are the symptoms of a failing hydraulic piston pump on CAT 414E, 416E, 422E, or 428E backhoe loaders?
A: Common signs include slow or weak loader lift and tilt response, the backhoe dig function losing power or stalling under load, hydraulic oil overheating during normal operation, whining or knocking noise from the pump area, and visible hydraulic fluid leakage. The 414E, 416E, 422E, and 428E are widely used in construction and municipal work — pump failure affects both the front loader bucket and rear backhoe digging performance simultaneously.
Q: Does the 2477867 fit all four backhoe loader models?
A: Yes, the 2477867 (247-7867) is designed as a direct OEM-compatible replacement for the CAT 414E, 416E, 422E, and 428E backhoe loaders. These models share the same pump mounting and hydraulic system architecture. Contact us with your backhoe serial number to confirm exact compatibility.
Q: What hydraulic functions does this pump support on a backhoe loader?
A: As the main hydraulic pump, it supplies flow to both front loader circuits (lift, tilt) and rear backhoe circuits (boom, stick, bucket, swing). It also supports auxiliary functions such as stabilizer legs and steering. A failing pump causes weak operation across all these functions — if only one function is affected, the problem may be a control valve rather than the pump itself.
Q: Should I flush the hydraulic system when replacing this pump?
A: Always. Flushing is essential — metal contaminants from the old pump can destroy the new pump within hours. Drain and replace all hydraulic oil, flush the system with clean oil, replace all filters, and refill with fresh Cat HYDO Advanced hydraulic oil. Backhoe loaders in construction and municipal applications are exposed to dirt and debris — a thorough flush is critical for long pump life.
Q: What type of hydraulic oil is recommended for the 414E, 416E, 422E, and 428E?
A: Caterpillar specifies Cat HYDO Advanced 10W or 30W depending on operating temperature. Backhoe loaders in construction, utility, and municipal applications should use Cat-approved fluids to ensure long pump life and maintain warranty coverage.
Q: How do I confirm this is the correct pump for my backhoe loader?
A: Check the part number on your current pump — if it reads 2477867 or 247-7867, this is the correct replacement. If the label is worn or missing, provide your backhoe serial number and we will verify compatibility before you order.
Q: Does this pump come with mounting hardware or gaskets included?
A: The pump is supplied as a complete unit. Depending on your backhoe configuration, you may need separate mounting bolts, gaskets, or O-rings. Contact us with your serial number and we will confirm exactly what is included and what additional parts you may need for installation.
Q: What is the warranty on this hydraulic piston pump?
A: This piston pump comes with a 12-month warranty covering manufacturing defects. The warranty does not cover damage caused by contaminated hydraulic oil, improper installation, failure to flush the hydraulic system, or using non-CAT approved hydraulic fluids.
