177-2577 Gear Pump supports CAT330C hydraulic oil delivery for B2B excavator parts repair, replacement stocking, and wholesale sourcing.
The 177-2577 Gear Pump YNF16828 is supplied for compatible CAT330C excavator hydraulic applications. Mechanical rotation is converted into hydraulic oil flow through the internal gear mechanism, allowing oil to be delivered to the corresponding machine circuit during operation.
The supplied product information includes a 9T reference. Because the exact meaning and measurement basis of this specification have not been provided, it should be compared directly with the original pump rather than being assumed from the reference alone.
For B2B buyers, the 177-2577 Gear Pump should be verified by part number, CAT330C machine information, shaft configuration, mounting flange, hydraulic port arrangement, rotation direction, overall dimensions, and existing-pump photos. Gear pumps with similar housings may use different internal displacement, shafts, ports, or mounting patterns. Accurate physical comparison before bulk purchasing helps reduce incorrect inventory, workshop delays, customer claims, and unnecessary international freight.

Q: What does the 9T specification mean?
A: It is supplied as a 9T configuration reference. Its exact measurement or structural meaning should be confirmed against the original pump.
Q: What does the gear pump do?
A: Mechanical rotation is converted into hydraulic oil flow for the corresponding machine circuit.
Q: Is the exact hydraulic circuit confirmed?
A: No. The installation circuit should be verified according to the machine and existing pump.
YNF Machinery supplies 177-2577 hydraulic gear pumps for CAT330C excavator workshops, hydraulic repair companies, machinery dealers, wholesalers, fleet operators, and international importers.
The YNF16828 gear pump is a configuration-sensitive hydraulic component. The supplied information includes a 9T reference, but this specification should be compared with the original pump together with shaft form, flange layout, port positions, and rotation direction before quantity purchasing.
Professional B2B buyers can provide the 177-2577 part number, CAT330C machine information, required quantity, pump nameplate, shaft photos, mounting dimensions, hydraulic port arrangement, 9T detail photos, and clear images of the removed pump for fitment confirmation.
Hydraulic motors, control valves, pump couplings, hydraulic hoses, filters, seal kits, oil coolers, and related CAT330C hydraulic parts can also be consolidated into the same inquiry to simplify procurement and reduce fragmented shipping costs.
