4120000866 CBGJ2063/2040 SDLG LG936 LG936L Tandem Hydraulic Gear Pump

4120000866 CBGJ2063/2040 SDLG Tandem Hydraulic Gear Pump

Olive Branch Hydraulics supplies a replacement tandem gear pump identified by SDLG material number 4120000866 and model CBGj2063/2040. SDLG LG936 and LG936L parts documentation identifies this component as a steering and transmission tandem pump. Use the material number together with the machine serial number, complete original pump model and installation photographs to select the correct configuration.

Material Number and Model Names

Compatible Equipment References

LG936 and LG936L are useful identification references for customers searching by machine model. They do not establish universal fit across every production year. Hydraulic layouts, mounting arrangements and replacement revisions can differ. A pump with the same family name should be checked against the removed unit before installation.

Installation Parts in the LG936L Catalogue

These numbers identify nearby installation components rather than alternative numbers for the complete pump. Check the parts diagram to determine which seals and flange components must be replaced. Installation accessories are separate quotation items unless explicitly included in the confirmed supply scope.

Construction and Technical Selection

The pump contains two coupled external gear-pump sections driven by one input shaft. Its separate connections serve the machine hydraulic arrangement. The 63/40 designation is a model-code reference; confirm actual displacement per section from the supplied-pump specification before calculating flow. Replacement listings describe a six-spline configuration, but spline count alone is insufficient to select the shaft. Diameter, tooth profile, engagement length and shaft projection must also match.

Measure the mounting pilot, bolt centres, flange thickness and installation clearance. Compare inlet and outlet positions, port opening sizes, flange bolt pitches and seal seats. Verify rotation from the original pump arrow and the specified shaft-end viewing direction. Pump colour and external similarity do not replace these checks.

Operating Parameters and Flow

Continuous pressure, intermittent pressure, maximum speed, oil-temperature limits and viscosity limits must be confirmed for the actual supplied configuration. A machine relief-valve setting should not be presented as the pump pressure rating. Follow the machine service instructions and the replacement-pump specification when selecting fluid and commissioning the system.

With verified displacement in cm3/rev, theoretical section flow in L/min equals displacement multiplied by shaft speed in rpm and divided by 1,000. Delivered flow also depends on volumetric efficiency, pressure, oil temperature and pump condition. Keep the two sections and their connections clearly identified when comparing hydraulic requirements.

Quotation Information

Send material number 4120000866, the LG936 or LG936L machine serial number, complete pump model, and readable photographs of the original label, shaft, mounting face and all ports. If the nameplate is missing, provide measurements and the machine parts-diagram reference. Olive Branch Hydraulics uses these details to check the replacement configuration before shipment.

Frequently Asked Questions

Is CBGJ2063/2040L always identical to CBGj2063/2040? The L suffix is part of the configuration reference and must be matched to the original pump and rotation requirement.

Are 29110000041 and 4030000026 replacement pump numbers? No. They identify a gasket and an O-ring used in the installation, not the complete tandem pump.

How should I search or request this product? Use 4120000866 SDLG gear pump, CBGJ2063/2040 tandem pump, or LG936L steering transmission hydraulic pump, then confirm the complete configuration.
