Frequently Asked Questions
Q: What are the symptoms of a failing hydraulic piston pump on a CAT 980G II wheel loader?
A: Common signs include slow or weak lift and tilt response, the loader bucket hesitating or stalling when raising heavy loads, hydraulic oil overheating during normal loading cycles, whining or knocking noise from the pump area, and visible hydraulic fluid leakage. The 980G II is a large wheel loader used in high-production mining, quarry, and construction — pump failure causes significant throughput loss and should be addressed immediately.
Q: Which CAT models does the 2093258 piston pump fit?
A: The 2093258 (209-3258) is designed as a direct OEM-compatible replacement for the CAT 980G II wheel loader. The 980G II is a large wheel loader commonly used in mining, quarry, and heavy construction applications. Contact us with your 980G II serial number to confirm exact compatibility.
Q: What hydraulic functions does this pump support on the 980G II?
A: As the main hydraulic pump on the 980G II, it supplies flow to the lift and tilt circuits (bucket functions), steering system, and any auxiliary circuits. A failing main pump will cause weak or slow operation across all functions simultaneously. Given the 980G II's size and production demands, pump issues should be diagnosed and addressed promptly to avoid expensive downtime.
Q: Should I flush the hydraulic system when replacing this pump on a 980G II wheel loader?
A: Always. Flushing is essential — metal particles and 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. We strongly recommend professional installation by a qualified technician or CAT dealer service center.
Q: What type of hydraulic oil is recommended for the CAT 980G II?
A: Caterpillar specifies Cat HYDO Advanced 10W or 30W depending on ambient operating temperature. For a large wheel loader working in mining or quarry applications under constant heavy load, using non-CAT approved fluids can cause immediate pump failure, accelerated wear, and void the warranty.
Q: How do I confirm this is the correct pump for my 980G II?
A: Check the part number on your current hydraulic pump — if it reads 2093258 or 209-3258, this is the correct replacement. If the label is worn or missing, provide your 980G II 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 980G II 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.
