4120003676 SDLG LG946L Loader Tandem Hydraulic Gear Pump

Product Overview: 4120003676 SDLG LG946L Gear Pump

Part number 4120003676 is a tandem hydraulic gear pump for the SDLG Lingong LG946L wheel loader hydraulic system. Olive Branch Hydraulics manufactures this wheel loader replacement pump in Xinji, Hebei, China, under catalogue reference MODEL-025 / SKU OBH-LD-025.

The full pump model designation is not confirmed. The exact hydraulic circuit and machine serial range must be checked against your unit before ordering.

Match by part number first, then by physical interface.

We build this Lingong LG946L tandem hydraulic pump against your sample or drawing and quote on EXW terms.

Key Features

• Two-section tandem housing: Two pump sections share one drive line in a black housing. Each section can supply a separate circuit.
• Projecting splined shaft: Drive input is through an external splined shaft. Tooth count, diameter and length are verified against your old pump before production.
• Front flange mount: A front mounting flange locates the pump on the drive housing. The bolt pattern and pilot must match your machine exactly.
• Large upper square side connection face: One square-pattern port face sits on the upper side of the body. Bolt spacing and bore are confirmed from your sample.
• Smaller lower square connection face: A second, smaller square port face sits lower on the body. Its position helps tell this pump apart from similar tandem units.
• Sample- and drawing-based build: Interfaces are reproduced from your physical sample or engineering drawing, not estimated from photos alone.
• Packaging and labelling: White-label and custom packaging are available, subject to confirmation per order.

Technical Specifications

No numerical ratings are published for this pump. Displacement per section, rated pressure, speed, rotation, spline tooth count, dimensions, weight and material grades are unknown, and we do not infer them from the part number.

Fitment is confirmed by checking the physical interfaces against your machine.

Fitment Checklist Before Ordering
