Select the replacement using the complete original pump designation, machine serial number and installation measurements.

Material Numbers and Cross References

Full Model Names and Search Spellings

Manufacturer supplier documentation identifies 1121302385 as P124B085**ZA12-**BPZA12-1/Y200. The asterisks are placeholders for configuration characters, not a complete ordering code. Marketplace references also associate 1121302385 with P124-G25085BL54/G25DIGL. Preserve all suffix characters when comparing a quotation with the old nameplate. P124 G25085BL54 G25DIGL is a spaced search spelling of that reference, while P124 alone names a family with many configurations.

Motor Grader Applications

These references support identification for customers searching by machine model or material number. They do not mean every production version uses an identical pump. A related part number may represent a different displacement, port arrangement or machine generation. The machine parts book and existing pump determine the correct supplied configuration.

Construction and Installation Checks

The illustrated pump uses a front mounting flange, a splined shaft and two external gear-pump sections. Compare the flange pilot diameter, mounting-hole centres, shaft projection, spline profile and port sealing faces. Check every inlet and outlet connection before reconnecting hoses. The direction arrow must agree with the machine drive direction when viewed from the specified end. Pump colour is a visual reference and does not establish fitment.

Operating Data and Fluid Guidance

P124 manufacturer-family guidance recommends fluid viscosity of 9–220 cSt, filtration of 10 micron with Beta 200, and maximum fluid temperatures of 82 °C for mineral oil or 57 °C for water glycol. Family inlet guidance limits vacuum to 0.237 bar for mineral oil or 0.101 bar for water glycol. These are family reference conditions, not certification of every replacement supplied under 803011197. Confirm oil compatibility, seal material and the machine service requirements for the selected pump.

Section displacement, continuous pressure, intermittent pressure and maximum operating speed must come from the supplied configuration datasheet. Flow in L/min is calculated from verified displacement in cm3/rev multiplied by rpm and divided by 1,000, then adjusted for volumetric efficiency. Avoid using machine relief pressure as a substitute for pump ratings.

Quotation and Replacement Identification

For an accurate quotation, send 803011197 or 1121302385, the machine model and serial number, a readable original nameplate, and photos of the shaft, mounting face and all ports. Include the complete model suffix if available. Olive Branch Hydraulics can use these details to check the replacement specification before shipment.
