W-01-0276 JHP3100/GJ1020-XF R Changlin Tandem Gear Pump for SINOMACH Wheel Loaders

Product Overview

Part W-01-0276, full model JHP3100/GJ1020-XF R, is a tandem hydraulic gear pump for the Changlin SINOMACH wheel loader hydraulic circuit. Olive Branch Hydraulics manufactures it in Xinji, Hebei, China, and lists it as catalogue MODEL-018, SKU OBH-LD-018.

The exact loader model, serial range and circuit function are not fixed in our catalogue. Each order is matched against the buyer's old pump before quotation.

The full model string, including the final R, is kept exactly as marked. A pump sold under a shortened code is not treated as an equivalent.

Key Features

• Tandem layout: Two gear pump sections share one blue housing and one input shaft, replacing a two-section unit in a single fitting.
• Upper port face: The upper section has a rectangular side port face.
• Lower port face: The lower section has a smaller polygonal port face. Hose and flange adapters must match each face separately.
• Front flange mounting: The flange bolts directly to the drive housing.
• Splined input shaft: The pump is driven through a splined shaft. Tooth count and spline standard are verified against the old pump, not assumed.
• Sample- or drawing-based build: OEM/ODM orders are produced to the buyer's sample or drawing. Packaging and label options are confirmed per order.

Technical Specifications and Fitment Check for JHP3100 GJ1020

Displacement, rated pressure, speed, rotation, dimensions and material grades are not published for this part. We do not derive them from the 3100/1020 digits or the R suffix.

Practical Fitment Checklist

1. Photograph the old pump nameplate, including the full suffix and final R.
2. Record the loader model and serial number from the machine plate.
3. Note which section is front and which is rear, and which circuit each feeds.
4. Map each port face (upper rectangular, lower polygonal) to its hose or line.
5. Count the shaft spline teeth and measure the flange bolt pattern.
6. Confirm rotation from the old pump marking or the drive layout.

FAQ

Does W-01-0276 fit every Changlin loader?

No. Fitment is confirmed per machine against the old pump, its nameplate and the loader serial number.

Is JHP3100/GJ1020-XF R the same as JHP3100/GJ1020?

Not necessarily. The XF and R suffix are kept exactly, and a pump without them is checked before it is offered as a substitute.

What rotation does the R indicate?

We do not assign rotation from the R. Rotation is confirmed from the old pump or the drive layout.

What is the displacement of each section?

It is not published here. Send the nameplate or drawing and each section will be matched to it.

What are the trade terms and MOQ?

Prices are quoted EXW Xinji, Hebei. MOQ and delivery depend on the configuration and packaging chosen.
