Large Hydraulic Oil Tank Cap closes the reservoir filling port for B2B excavator parts repair, maintenance, stocking, and wholesale sourcing.
The Large Hydraulic Oil Tank Cap YNF17631 is supplied for compatible excavator and construction machinery hydraulic reservoirs. It is installed at the hydraulic oil filling or service opening so the reservoir can be closed after oil inspection, refilling, or maintenance work has been completed.
This product is identified as the large-size version, making physical fitment confirmation especially important. Hydraulic tank caps with similar appearances may still use different diameters, locking structures, threads, sealing interfaces, or filler-neck designs.
For B2B buyers, the YNF17631 cap should be compared with the removed part by overall diameter, connection method, filler-neck dimensions, sealing area, and clear photos before quantity purchasing. No specific machine model or OEM reference has been supplied for this listing, so fitment should not be assumed from appearance alone. Accurate verification helps distributors reduce incorrect stock, customer returns, and unnecessary international freight.

Q: What should be checked before ordering?
A: Cap diameter, filler-neck dimensions, connection structure, sealing interface, and existing-part photos should be compared.
YNF Machinery supplies large hydraulic oil tank caps and related excavator hydraulic parts for repair workshops, machinery dealers, hydraulic service companies, wholesalers, and international importers.
The YNF17631 hydraulic reservoir cap is identified as a large-size version. Since no specific machine model or OEM reference has been provided, dimensional and structural comparison should be prioritized before bulk ordering.
Professional buyers can provide the YNF17631 number, required quantity, cap outside diameter, filler-neck dimensions, connection or locking structure, and clear photos of both the old cap and hydraulic tank opening for fitment checking.
Hydraulic filters, tank strainers, hoses, pumps, valves, seals, and other excavator hydraulic components can also be included in the same inquiry, helping B2B buyers consolidate replacement stock into fewer shipments.
