Caterpillar 3G2751

3G2751 is a Caterpillar cartridge kit for a vane-type hydraulic pump—specifically the 20VQ11N cartridge used in select CAT machines. The cartridge is a right-hand rotation (Rot R) unit that carries a Vickers reference of 416427 and lists a displacement of Gal 11. Alternate identifiers found in catalogs include 0R-1464, reflecting cross-reference mappings for the same vane-pump kit. This kit is designed as a direct replacement for the pump cartridge within the 20VQ11N assembly and is typically installed in Caterpillar loaders such as the 988A, restoring hydraulic flow and pressure performance without replacing the entire pump housing. When replacing, technicians remove the old cartridge, install the 3G2751 assembly, and reassemble per the hydraulic system’s service procedure. The 3G2751 cartridge kit is intended for maintenance and repair on legacy Caterpillar equipment, and is commonly used by service professionals performing vane-pump cartridge rebuilds to extend the service life of hydraulic systems in machines like the 988A loader.
