15852-33140 Oil Filler Cap protects the lubrication filling port for B2B excavator parts maintenance, replacement inventory, and wholesale sourcing.
The 15852-33140 Oil Filler Cap YNF17963, with YJ-C012-019 supplied as an additional reference, is used to close the lubrication oil filling opening on compatible Kubota diesel engines. After engine oil has been checked or replenished, the filler opening is covered by the cap so direct exposure to external contamination can be reduced.
Oil filler caps are small maintenance components, but proper fitment is important in construction machinery that is routinely operated in dusty environments. A damaged, missing, cracked, or incorrectly matched cap may leave the lubrication-system opening insufficiently protected.
For B2B buyers, the 15852-33140 Kubota oil filler cap should be checked by both reference numbers, filler-neck configuration, cap diameter, fastening structure, sealing interface, and existing-part photos. Since no specific engine model has been supplied, reference-number and physical comparison should be prioritized before bulk purchasing.

YNF Machinery supplies 15852-33140 / YJ-C012-019 Kubota oil filler caps for machinery repair workshops, engine parts dealers, wholesalers, and international importers.
The YNF17963 oil cap is a compact maintenance item that can be conveniently stocked with filters, gaskets, dipsticks, oil pumps, and other engine service parts. Because similar-looking caps may use different filler-neck dimensions or fastening structures, fitment should be checked before quantity purchasing.

Related Kubota engine maintenance components can also be included in the same inquiry, helping distributors build practical replacement inventory and consolidate international shipments.
