Specifications follow the supplied series drawing. Maximum pressure is a catalogue limit, not a continuous-duty guarantee. Flow is calculated as displacement × speed / 1000 and is not a measured delivery value. Length L excludes the projecting drive shaft; configuration-specific dimensions must be checked.
Mounting and Ordering Options
| Item | Specification |
|---|---|
| Mounting pilot | 85 mm |
| Mounting-slot centre distance | 130 mm |
| Mounting-slot width | 11 mm |
| Body | Aluminum alloy |
| Ports | Threaded or flange configuration: confirm complete code |
| Shaft options | Plain key or rectangular spline: confirm drawing |
| Rotation | CW or CCW configuration: confirm complete code and direction reference |
Product Information
Product Overview
CBF series hydraulic gear pumps use an aluminum-alloy housing and are available in multiple displacement and drive configurations. This catalogue configuration uses an 85 mm mounting pilot and 130 mm mounting-slot spacing. Select the complete pump code to match displacement, shaft, ports and rotation.
Product photographs illustrate the available pump configurations. Confirm the exact mounting, shaft and port arrangement against the selected full model code.
Part Numbers and Equipment Catalogue References
The following references identify pumps listed in equipment catalogues. They are not a claim that every pump in this series fits every listed machine. Match the complete code, machine serial number, mounting pilot, shaft and ports before ordering.
| Complete pump code | Part / material number | Equipment reference | Catalogue location |
|---|---|---|---|
| CBF-F425-ALPL | Pump model used as part number; no separate numeric code verified | Farmer Helper BH5 backhoe attachment | BH5 manual: pump assembly, printed page 20 |
Replacement Matching
Send the original pump code, equipment model and serial number, displacement, rotation direction, pilot diameter, mounting spacing, shaft dimensions and port details. We will check the requested configuration before confirming a replacement.
Part Number Search Guide
CBF-F425-ALPL is the hydraulic pump part number printed in the Farmer Helper BH5 and Value-Leader BHM8 backhoe manuals. Buyers searching for a CBF-F425-ALPL backhoe hydraulic pump can quote this complete code. BHM8 manual section 7.0 lists the pump using this code; it does not assign a separate numeric pump number. Confirm the pump and PTO drive assembly separately.
