| Supply identity | Olive Branch Hydraulics aftermarket replacement; OEM numbers used for identification and fitment reference |
Olive Branch Hydraulics supplies aftermarket tandem gear pumps selected by the original material number and installation configuration. This page covers the Lovol FL936F transmission-pump reference 9D651-31A010000A0 and the associated CBGj1032/1010-XF designation. The supplied product catalogue also uses JHP1032/1010. A replacement quotation should identify the final model, shaft, mounting, port layout and hydraulic requirements rather than relying on a shortened series name.
| Search reference | Meaning and ordering use |
|---|---|
| 9D651-31A010000A0 | Full part-number spelling in supplier transmission-system lists |
| 9D651-31A01000A0; 9D651/31A01000A0 | Shorter spelling in supplied catalogue and supplier product titles |
| 9D630-530100; 9D630-5301000 | Associated CBGj1032/1010-XF pump references in supplier listings |
| 96D630-530100 | Supplied-workbook and JHP supplier-title spelling; confirm the original code |
| CBGj1032/1010-XF; CBGJ1032-1010-XF | Capitalization and punctuation variants used for this pump |
| JHP1032/1010; JHP1032-1010 | Alternate model search; interchangeability requires configuration comparison |
Keep every digit and suffix when requesting a pump. Catalogue transcription can change the number of zeros or replace a hyphen with a slash. These strings help identify the relevant product family; they do not establish that every item sold under a similar title has the same mounting or performance. Send a readable picture of the old label with the enquiry.
| Equipment reference | Selection status |
|---|---|
| Foton Lovol FL936 / FL936F | Direct supplier application for the tandem transmission/hydraulic pump |
| FL935E / FL938G | Supplier catalogue-category reference; match the machine serial number before ordering |
| Shantui SL30W (new) | Additional supplier catalogue association; confirm the exact transmission installation |
| TD226 / WP6G125E | Supplier-listed engine reference; verify pump drive and equipment configuration |
Identify the circuit served by each section before replacement. A loader can carry separate working, steering and transmission pumps. Matching only the loader name or engine model can therefore produce the wrong part. The original pump code, transmission configuration and inlet/outlet arrangement provide a more useful comparison.
A supplier FL936F parts catalogue records CBGj1032/1010-XF with a speed reference of 2300 r/min and a pressure notation of 20/3.5 MPa. Those pressures convert to 200/35 bar. This is a catalogue reference, not an independently verified maximum-pressure rating for every replacement. Confirm which section corresponds to each value, the permitted continuous and intermittent pressures, and the actual pump drive speed.
The 32/10 size-code interpretation must be checked against the exact displacement sheet. Once displacement is confirmed, theoretical section flow in L/min equals displacement in cm³/rev multiplied by pump rpm, divided by 1000. Actual delivery depends on efficiency, oil condition and pressure. Specify the required test speed, pressure and oil temperature when requesting a performance report.
The shaft-end reference photograph shows a spline drive and a two-hole mounting flange. Measure the spline profile, tooth count, shaft diameter, projection and engagement length. Record the locating pilot, bolt centres and flange thickness. Confirm all port sizes, flange-hole patterns and sealing faces; protective plugs do not establish the underlying connection specification.
Rotation must be confirmed from the original direction mark using the agreed shaft-end viewing convention. Check the old drive coupling for wear before fitting the new pump. Final outline dimensions, net weight, seal material, oil viscosity and temperature limits are configuration-specific and should appear on the approved quotation or drawing.
| Separate component | Reference |
|---|---|
| Connecting sleeve | 9D650-31A000005A0 |
| Pump mounting flange | 9D650-31A000004A0 |
| Low-pressure filter assembly | 9D650-31A030000B0 |
| Filter cartridge | 9D650-31A030200A0 |
These numbers identify associated transmission-system components, not alternative complete-pump material numbers. Specify pump-only supply or any required connecting parts separately so the quotation is clear.
The gallery combines the supplied catalogue product image with supplier-reference side and shaft-end views. Overlay watermarks on the reference views have been removed for presentation. Colour and external details can vary by configuration; confirm the actual shipment photographs and drawing before delivery.
For selection, provide the old material number, complete model suffix, machine serial number, transmission identification, shaft-end photo and clear views of every oil connection. State the quantity and destination. Olive Branch Hydraulics can discuss sample matching, OEM/ODM and the inspection requirements agreed for the order.
Can I search by JHP1032/1010 or 9D630-530100? Yes. These references are included to help customers locate the pump family, followed by configuration confirmation.
Does a FL936F model name guarantee fitment? No. Match the original pump and installation details, including rotation and the section-to-circuit connections.
Are the related flange and filter included? They are separate service references. Inclusion depends on the confirmed quotation.
