Olive Branch Hydraulics manufactures the 4110015875 / CBGJ0025 SDLG gear pump in Hebei, China, as an aftermarket replacement for the Lingong auxiliary pump on SDLG wheel loaders. Our catalog lists it under SKU OBH-LD-065, described as a low-pressure auxiliary hydraulic gear pump.
Some supplier tables list the same part number as an SDLG transmission pump, cross-referenced to CBJj0025A. Because the two descriptions differ, every order starts with a fitment check against the buyer's original pump.
Only catalog data is listed below. Unverified dimensions are marked for confirmation, not estimated.

Have the old pump's nameplate at hand?A clear photo of the nameplate, shaft end and port side is enough to start the fitment check for 4110015875.
The unit is listed under 4110015875, CBGJ0025 and SKU OBH-LD-065 in our own catalog, so quotes and repeat orders use one reference.
The unit has a black pump body and blue protective port covers. These are photos of a real unit, not renders.
The gallery shows the complete pump, a direct shaft/flange crop and a covered-port/body crop for visual comparison.
Displacement, rotation and mounting dimensions are not published as specifications. They are verified against your sample or drawing.
CBGJ0025 and CBJj0025A are recorded as separate references. A suffix match is not treated as proof of interchangeability.
We produce hydraulic gear pumps and aftermarket replacement components in Hebei, China.
Every quote cites part number, model and SKU OBH-LD-065. This keeps reorders traceable to the same specification.
We accept sample-based and OEM/ODM enquiries. A customer's original pump or drawing serves as the reference for matching.
