381727 DYNAPAC Gear Pump is an original factory hydraulic component for B2B construction machinery repair, replacement inventory, and wholesale sourcing.
The 381727 DYNAPAC Gear Pump YNF16417, also referenced by 8400088 and 4700396079, is supplied as an original factory hydraulic component for compatible DYNAPAC construction machinery. Mechanical rotation is converted into hydraulic oil flow by the internal gear set, allowing the corresponding hydraulic circuit to receive the fluid supply required for machine operation.
Because the exact machine model and hydraulic circuit position have not been supplied, the pump should be identified primarily through the reference numbers and physical configuration. Shaft style, mounting flange, rotation direction, inlet and outlet ports, overall dimensions, and existing-pump appearance should all be compared before ordering.
For B2B buyers, using an original-specification pump can simplify replacement when a direct configuration match is required. Before bulk purchasing, 381727, 8400088, and 4700396079 should be cross-checked together with machine information and pump photos to reduce incorrect inventory, installation delays, and costly international returns.

Q: Are 381727, 8400088, and 4700396079 related references?
A: They are supplied as reference numbers for this product and should be cross-checked during fitment confirmation.
Q: Is the exact DYNAPAC machine model confirmed?
A: No. The exact machine application should be verified before ordering.
Q: Is this an aftermarket pump?
A: No. The supplied product information identifies it as an original factory part.
YNF Machinery supplies 381727 / 8400088 / 4700396079 DYNAPAC gear pumps for road-machinery workshops, hydraulic repair companies, construction-equipment dealers, wholesalers, fleet operators, and international importers.
This YNF16417 gear pump is supplied as an original factory part, making it suitable for buyers who prioritize original configuration when replacing hydraulic components. Because gear pumps can appear similar while using different shafts, flanges, ports, rotation directions, and displacement specifications, identification should not be based on appearance alone.
Professional buyers can provide the 381727, 8400088, or 4700396079 reference, DYNAPAC machine model, serial information, required quantity, pump nameplate, shaft photos, port arrangement, and dimensions for fitment confirmation.
Hydraulic motors, control valves, seal kits, hydraulic hoses, filters, couplings, and other construction-machinery hydraulic parts can also be consolidated into the same inquiry for more efficient B2B procurement.
