JCB Hydraulic Gear Pumps: Model And Interface Guide

Find your pump by reference number, then confirm the interfaces. Olive Branch Hydraulics supplies hydraulic gear pumps for JCB backhoe-loader and telehandler applications. This selection guide brings together 13 catalogue groups and 28 enquiry references, with a separate identification section for each group.

We offer original-equipment quality (原厂原装品质) under the Olive Branch Hydraulics brand. JCB model names and part references identify the intended application. Final supply is matched to the machine PIN and approved configuration drawing.

Ready to enquire? Send the number from your pump, machine model and PIN, photographs of the shaft and ports, and required quantity through this page's enquiry form.

332/G7134 · 20/903000 · 20/925366 · 20/925337 · 20/925472 · 20/925592 · 7049520006 · 20/925647 · 334/Y1469 · 332/T4833 · 20/925732 · 20/925588 · 20/925591

Numbers grouped together below follow the catalogue's enquiry grouping. They do not establish unconditional interchangeability. Equipment names indicate applications to investigate; confirm the specific machine build before ordering.

Check these interfaces before choosing a pump

1. Identify the machine and reference. Record the full machine PIN and every character on the pump plate. A 3CX or telehandler family name alone is not enough.
2. Check the drive. Distinguish a straight keyed shaft from a splined shaft or a pump supplied with an external drive gear. Measure engagement length and photograph the coupling.
3. Check the mounting flange. Record pilot diameter, fixing-hole count and centre distances. Count mounting holes on the front flange, separately from oil-connection bolts on the body.
4. Map all hydraulic connections. Identify inlet and each outlet from machine documentation. Record port size, connection type, orientation and any external block.
5. Confirm each section's specification. Agree displacement, rotation as viewed from the shaft end, operating requirements and overall envelope on the configuration drawing. These values cannot be determined reliably from a photograph.

332/G7134 — Tandem pump with splined input

Catalogue enquiry references: 332/G7134; 333/G5389. Compact reference notation: 332G7134, 333G5389.

Equipment enquiries: JCB 3CX backhoe-loader enquiries; selection is subject to PIN and configuration approval.

The catalogue configuration uses an oval two-bolt mounting flange and splined drive shaft. The large side connection has a four-hole attachment face. Compare the position of this connection with both outlets on your own pump; four oil-connection holes do not mean a four-bolt mounting flange.

Selection check: Confirm shaft engagement length, mounting pilot and port orientation before selecting this reference group.

20/903000 — Keyed-shaft tandem pump

Catalogue enquiry references: 20/903000. Compact reference notation: 20903000.

Equipment enquiries: JCB 3CX, 4C, 4CN and 3CXSM backhoe-loader enquiries; selection is subject to PIN and configuration approval.

This version has a straight keyed drive shaft rather than a splined shaft. Its oval mounting flange has two fixing holes. A similar-looking tandem body cannot identify the drive connection: inspect the keyway, shaft end and coupling together.

Selection check: Measure shaft diameter, key width and projection from the flange face; include a photograph of the mating coupling.

20/925366 — Tandem pump reference family

Catalogue enquiry references: 20/925366; 20/925586; 333/C5234; 333/G5392; 7029120009; 7029120022. Compact reference notation: 20925366, 20925586, 333C5234, 333G5392, 7029120009, 7029120022.

Equipment enquiries: JCB 214e, 214e-LE, 214e-LL and 214e-Turbo backhoe-loader enquiries; selection is subject to PIN and configuration approval.

The illustrated configuration has a splined input and oval two-bolt flange. This catalogue group contains several enquiry numbers. The number on the removed pump and the machine PIN are more useful than choosing by the 214e model name alone.

Selection check: Compare the large inlet connection, two outlet positions and overall body length against an approved drawing.

20/925337 — Splined-shaft tandem configuration

Catalogue enquiry references: 20/925337. Compact reference notation: 20925337.

Equipment enquiries: JCB 214E and 3C 14-B / 3C 14-T2 / 3C Plus enquiries; selection is subject to PIN and configuration approval.

The catalogue shows a tandem assembly with an oval two-bolt flange and splined input. Similar flange outlines occur on other references in this guide, so the front view alone is insufficient to select the hydraulic configuration.

Selection check: Provide a full side view and both port faces as well as the shaft photograph; confirm the machine build rather than assuming all 214E pumps match.

20/925472 — Two-bolt pump for 3DX enquiries

Catalogue enquiry references: 20/925472. Compact reference notation: 20925472.

Equipment enquiries: JCB 3DX, 3DXHM, 3DXL RCP, 3DX Super and 3DX ED enquiries; selection is subject to PIN and configuration approval.

An oval two-bolt flange and splined shaft identify the illustrated front interface. These visual features should be checked separately from hydraulic output. Machines within the 3DX family can require different configurations.

Selection check: Use the front view to check mounting-hole spacing and pilot diameter, then confirm displacement, rotation and outlet arrangement from the machine data and drawing.

20/925592 — Four-bolt pump with valve block

Catalogue enquiry references: 20/925592; 20/925357. Compact reference notation: 20925592, 20925357.

Equipment enquiries: JCB 526-56, 531-70, 533-105, 535-95, 536-70 and 541-70 telehandler enquiries; selection is subject to PIN and configuration approval.

The square front mounting flange has four fixing holes around the splined input. The catalogue configuration also includes an external valve block. The block is part of the interface comparison, including its connections and clearance around the installed pump.

Selection check: Send the valve-block view and the machine hydraulic information; appearance alone cannot establish valve settings or circuit functions.

7049520006 — Telehandler pump with external block

Catalogue enquiry references: 7049520006; 332/E6671. Compact reference notation: 7049520006, 332E6671.

Equipment enquiries: JCB 535-125, 535-140, 540-140, 540-200, 541-70, 550-140, 550-80 and 560-80 telehandler enquiries; selection is subject to PIN and configuration approval.

The illustrated assembly combines a square four-bolt flange, splined shaft and externally mounted block. Its shape can resemble the previous group, but the reference number, body sections and port details must be checked independently.

Selection check: Quote the exact number including every digit. Confirm the valve-block orientation and rear-section clearance before ordering.

20/925647 — Pump supplied with geared input

Catalogue enquiry references: 20/925647; 7029522013. Compact reference notation: 20925647, 7029522013.

Equipment enquiries: JCB SD80, PD80, PD55, S55, PD70, SD40 and PD40 machine enquiries; selection is subject to PIN and configuration approval.

This configuration is visually distinguished by the external gear at the input end. A pump offered as a bare shaft assembly may therefore differ from the arrangement you need, even when the hydraulic body appears similar.

Selection check: State whether the drive gear is required. Check its engagement, retention, mounting pilot, port connection and installed envelope against the machine arrangement.

334/Y1469 — Splined-input pump for 3DX enquiries

Catalogue enquiry references: 334/Y1469. Compact reference notation: 334Y1469.

Equipment enquiries: JCB 3DX backhoe-loader enquiries; selection is subject to PIN and configuration approval.

The catalogue illustration shows an oval two-bolt flange, splined input and tandem body. Keep this reference separate from 20/925472 during selection; sharing a machine-family description does not establish the same hydraulic or mechanical specification.

Selection check: Identify the stamped reference and PIN, then compare both outlet positions, input spline and mounting dimensions.

332/T4833 — Compact multi-section configuration

Catalogue enquiry references: 332/T4833. Compact reference notation: 332T4833.

Equipment enquiries: JCB 524 and 527 telehandler enquiries; selection is subject to PIN and configuration approval.

This assembly has a splined input, oval mounting flange and compact front-to-rear arrangement. The side-port face and rear section are useful identification views. Check available space for the pump and hose connections inside the machine.

Selection check: Include overall length, rear clearance and inlet/outlet views with your enquiry; do not judge fitment from shaft type alone.

20/925732 — Multi-section pump with valve block

Catalogue enquiry references: 20/925732; 20/925613. Compact reference notation: 20925732, 20925613.

Equipment enquiries: JCB 540-170 and 550-170 telehandler enquiries; selection is subject to PIN and configuration approval.

The catalogue group shows a square four-bolt mounting interface and a multi-section body with external block. The rear view helps identify the additional section and its connections. Section output and valve configuration must be specified separately.

Selection check: Supply front, rear and block-side photographs plus the machine PIN. Confirm the complete assembly rather than only the front pumping section.

20/925588 — Multi-section telehandler pump family

Catalogue enquiry references: 20/925588; 20/925356; 20/918500; 7029530002. Compact reference notation: 20925588, 20925356, 20918500, 7029530002.

Equipment enquiries: JCB telehandler enquiries identified by these pump references; selection is subject to PIN and configuration approval.

This catalogue group uses a square four-bolt flange, splined input and extended multi-section assembly. The additional reference numbers belong to the same catalogue enquiry group; they are not a declaration that every machine build uses an identical pump.

Selection check: Compare the rear-section length, port positions and block arrangement. Send the exact machine model and PIN before choosing a configuration.

20/925591 — Extended pump assembly with block

Catalogue enquiry references: 20/925591; 20/925355; 20/918300. Compact reference notation: 20925591, 20925355, 20918300.

Equipment enquiries: JCB 540S, 530S, 533-105, 540, 530SXL and 530SWAY telehandler enquiries; selection is subject to PIN and configuration approval.

The illustrated configuration has a square four-bolt mounting face, splined drive and extended pump body with an external block. It must be distinguished from the other multi-section groups by its actual reference, interfaces and hydraulic requirements.

Selection check: Confirm every pumping section, rotation and block connections on the drawing; request the complete assembly configuration in your quotation.

Send an enquiry that identifies the right configuration

Please provide the reference number, machine model and PIN, quantity, shaft-end photograph, inlet and outlet photographs, and any available dimensioned drawing. For pumps with an external block or drive gear, include those components in the photographs. If the original plate is unreadable, clear measurements and several views are especially useful.

Our team reviews the mechanical and hydraulic requirements before confirming a configuration and EXW quotation. Trial quantities and OEM/ODM enquiries are welcome. Shaft, flange, port, label and carton requirements can be discussed against the approved drawing. Inspection is arranged before dispatch; quantity, price and timing are confirmed in the quotation.

International enquiry terminology

You may describe your requirement as a hydraulic gear pump for JCB, tandem hydraulic pump or multi-section telehandler pump. Spanish: bomba hidráulica de engranajes; French: pompe hydraulique à engrenages; Russian: шестерённый гидронасос. Include the part reference in any language so we can identify the same configuration.

Frequently asked questions

Can I order using only a part number?

The part number starts the selection process. Add the machine PIN and interface photographs so we can confirm the actual build, drive and hydraulic connections.

Are the numbers in one group automatically interchangeable?

No. They are catalogue enquiry references. Any cross-reference needs a drawing and machine-configuration check before supply is confirmed.

Why do several pumps look almost the same?

Similar housings can have different shafts, displacement combinations, rotations, ports or valve configurations. Compare the complete specification rather than the outside shape alone.

Does a four-hole oil port mean a four-bolt pump flange?

No. Oil-connection fixing holes are on the hydraulic port face. The mounting-flange fixing holes are around the input shaft and must be checked separately.

What should I send for a pump with a valve block?

Include the block from several sides, its connections, the machine PIN and available hydraulic documentation. Do not infer settings or valve functions from a photograph.

Can you discuss a tandem or triple pump configuration?

Yes. Send the required section arrangement and hydraulic specification. Each section and its connections are checked on the proposed drawing before configuration approval.

Can I request a sample or private-label supply?

Trial orders and OEM/ODM enquiries are welcome. Tell us the configuration, quantity, label and packaging requirements; availability, sample arrangements and timing are quoted individually.

What are your supply terms?

Supply is quoted EXW Hebei, China. Confirm the reference group, approved configuration and quantity in your enquiry so the quotation covers the assembly you need.
