4120005046 CBGJ2063/2040A Tandem Pump for SDLG LG953N and LG955N Wheel Loaders

Product Overview

Olive Branch Hydraulics manufactures the CBGJ2063/2040A tandem gear pump for SDLG Lingong LG953N and LG955N wheel loaders. Our catalogue groups part numbers 4120005046, 4120008620 and 4120003067 under this model as catalogue entry MODEL-029, SKU OBH-LD-030.

These numbers are grouped references only. They are not automatically identical or interchangeable, so the configuration suffix, serial range and interfaces must be confirmed before you substitute one for another.

We produce at our plant in Xinji, Hebei, China, and supply OEM/ODM units on EXW terms from sample or drawing.

The gallery shows one original composite photo plus direct crops of its left view, right view and overall view. The crops are taken from the same image and do not show additional angles.

Key Features

• Tandem gear pump layout: The catalogue lists CBGJ2063/2040A as a two-section tandem unit. Do not quote or source it as a single pump based on the photo.
• Projecting splined drive shaft: The shaft is visible in both photo views. The spline count is not verified and must be matched against your original pump.
• Front mounting flange: Flange geometry decides whether the pump bolts straight into the loader. Check it before any substitution.
• Blue side port covers: The covers protect the ports in transit. Port threads and positions must be confirmed per configuration.
• Lower rectangular cover: This cover appears on the photographed unit. Compare it with the housing on the pump you are replacing.
• Yellow/orange finish: This is the finish shown in the photos. Colour and labelling can be changed for OEM and private-label orders after confirmation.

Technical Specifications: CBGJ2063/2040A Selection Points

Our current catalogue data does not verify displacement, pressure, speed, rotation, dimensions or weight for this pump. We do not derive these values from the "2063/2040" digits in the model code.

Base your selection on four checks:

1. The full part number and configuration suffix on your original nameplate: 4120005046, 4120008620 or 4120003067.
2. The loader model and serial range: LG953N or LG955N.
3. The shaft spline and flange pattern, measured or photographed from the old pump.
4. The port positions and thread types on both pump sections.

Practical Fitment Checklist

• Nameplate photo, plus any stamped housing numbers.
• Machine model and frame serial number.
• A clear end-on photo of the shaft, and a photo of the flange face.
• Side photos of both port faces, with fitting types noted.
• Rotation direction, if it is marked on the old pump.

Why Choose Us

Gear pumps and steering pumps are our core production lines in Xinji. Orders follow the buyer's sample or drawing, and each one is quoted EXW for its confirmed configuration.

MOQ and delivery depend on the configuration. They are stated in writing on each quotation rather than as a fixed catalogue figure.

FAQ: 4120005046 CBGJ2063/2040A Tandem Pump

Are 4120005046, 4120008620 and 4120003067 interchangeable?

Not automatically. They share one catalogue group, but the suffix and interfaces must be matched before substitution.

Does CBGJ2063/2040A fit every SDLG LG953N and LG955N?

No. Fitment depends on the loader's serial range and original pump configuration, so send both.

What displacement and pressure does this pump have?

These values are not verified in our catalogue data. We confirm them from your nameplate, drawing or sample.

Is this a single or tandem gear pump?

It is a tandem gear pump according to our catalogue. The photo alone should not be used to determine the type.

Can you supply samples and private-label packaging?

Yes. Samples are made to your drawing or sample, and packaging and label options are confirmed for each order on EXW terms.
