Product Overview

The 247-8888 hydraulic cylinder seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Caterpillar part number 247-8888 (also written 2478888). Independent parts stores identify the kit as the bucket cylinder seal kit for the Caterpillar 319D, 320D, 323D and 324D excavator family (partsasap.com “Hydraulic Seal Kit – Bucket Cylinder fits Caterpillar 320D 320DL 320DLN 324DL … 247-8888”; tractorpartsasap.com; suncar-seals “CA2478888 … Bucket Cylinder Seal Kit for C.A.T. Excavator 319D L, 324D”; wkzparts “247-8888 2478888 Caterpillar Excavator E320D Bucket Seal Kit”).

The kit reseals the bucket cylinder of the verified Caterpillar D-series excavators. DJF Seals manufactures and supplies the 247-8888 kit at factory-direct wholesale pricing for Caterpillar equipment dealers, repair shops and fleet maintenance programs.

Verified Application

The following application data was cross-checked against independent parts-store and marketplace listings:

Note: the current page carries a lengthy model list together with pressure, temperature, material, cycle-count and certification claims and states that the kit replaces Cat part numbers other than 247-8888. No independent source in this package confirms those figures or the additional part numbers, so they are treated as unverified factory data and are not repeated. Materials, pressure rating, temperature range, exact piece counts, certifications and service life are not independently verified.

Replacement Scope

This kit covers the sealing elements required to reseal the bucket cylinder of the verified Caterpillar 319D, 320D, 323D and 324D excavators. The verified reference is 247-8888 cross-referenced to the bucket cylinder position; the exact kit contents and piece counts should be verified with the factory against your cylinder before shipment.

Fitment Verification

The part number, bucket position and fitments were verified through multiple independent sources:

• partsasap.com: “Hydraulic Seal Kit – Bucket Cylinder fits Caterpillar 320D 320DL 320DLN 324DL … 247-8888” — establishing the part number, the bucket position and the 320D / 324D model rows.
• tractorpartsasap.com: the same kit listed for the 324D, 324DL, 324DLN, 324EL and 324ELN — corroborating the bucket position and extending the model rows.
• suncar-seals (Thailand): “CA2478888 247-8888 2478888 Bucket Cylinder Seal Kit for C.A.T. Excavator 319D L, 324D” — corroborating the bucket position and the 319D / 324D models.
• wkzparts: “247-8888 2478888 Caterpillar Excavator E320D Bucket Seal Kit” and a Facebook parts listing (“CA2478888 … 319D L, FM, 320D GC, 320D”) — corroborating the bucket position and the 320D family.
• Alibaba listing: “247-8888 266-7892 … E320D” — corroborating the number, the 320D application and the companion number 266-7892; a made-in-china listing groups 247-8888 with 247-8878 and 259-0631.
• eBay.ca listing: “for Caterpillar E319D, 320D, 323D, and 324D excavators” — corroborating the combined 319D / 320D / 323D / 324D model cluster stated above.
• Conflict note: the current page makes many performance and certification claims (pressure, temperature range, material grades, cycle counts, test figures, ISO references) and states that the kit replaces additional Cat part numbers. No independent source in this package confirms that data, so it is flagged as unverified and not asserted.
• Conflict note: a second DJF page using the same 247-8888 number positions the kit for the Caterpillar E320B / E320C / E320D machines, which differs from the 319D / 320D / 323D / 324D cluster confirmed by the independent listings above — an internal duplication to note rather than merge.
• Note on naming: 247-8888 is described here as an aftermarket replacement cross-reference, not as a genuine or OEM-original part.
• Materials, pressure, temperature, exact piece counts, certifications and service life are not independently verified.
