11C0353 P257-G63487ZGA6/P124-G20ING LiuGong CLG862 Steering Gear Pump

11C0353 Steering Gear Pump for LiuGong CLG862

The 11C0353 hydraulic steering pump is identified in the LiuGong CLG862 parts catalogue as P257-G63487ZGA6/P124-G20ING. This tandem external gear pump combines a P257 front section and a P124 rear section. Olive Branch Hydraulics accepts enquiries for an aftermarket assembly matched to the complete model, machine serial number and mounting interfaces.

Searching only for P257 or P124 can return many different configurations. Use the complete pump number and both model sections when requesting a quotation. The CLG862 equipment reference helps locate the correct application, while the shaft, flange, ports and rotation must still be checked before replacement.

Material Number, Model Names and Service References

Model punctuation and spacing may vary between catalogues. Preserve the suffix letters from the original nameplate rather than assuming every shortened listing is mechanically identical. No additional whole-pump OEM number is confirmed for this product here.

Compatible Equipment and Hydraulic Function

The CLG862 parts catalogue CLG8622008.05.004 identifies 11C0353 at item 6 of pump installation group 44C0060 003. The CLG862 operating manual CLG862-200904001 lists the corresponding P257/P124 assembly in the steering system. This supports the CLG862 steering-pump application. It is separate from the 11C0318 working-pump reference listed in the same equipment documentation.

The operating manual gives a steering-system pressure of 17.5 MPa, equivalent to 175 bar, and a flow reference of 127 L/min at 2200 rpm. These are equipment operating references. They do not establish the pump’s maximum permissible pressure or the combined flow of every tandem section. Confirm the installed configuration if the loader has been modified or uses a different production variant.

Performance Parameters and Series Limits

The Permco 257 technical brochure describes a cast-iron, sleeve-bushing pump with pressure-balanced plates. Its series chart covers approximately 21–105 cm³/rev and shows a maximum speed of 2400 rpm. The chart’s pressure limits vary with gear width, from 2500 to 4500 psi. These are P257 family references, not a certified performance sheet for every 11C0353 tandem assembly.

The G63 and G20 portions of the assembly code are useful capacity-designation references, but exact displacement for the supplied front and rear sections should be confirmed from the assembly drawing. A supplier catalogue lists a net weight of 31.3 kg for this reference; weight may change with supplied fittings and configuration. Exact dimensions and a production test sheet should be requested with the quotation.

Shaft, Flange, Ports and Installation Checks

Reference photos show a splined drive shaft and a two-bolt mounting flange. Check the spline tooth count, shaft diameter, usable engagement length, locating pilot and mounting-hole spacing against the removed pump. The trailing digit in the model must not be used by itself to determine the number of spline teeth.

Compare inlet and outlet positions, connection styles, port diameters and flange-hole patterns on both sections. Confirm rotation viewed from the shaft end. Correct material-number identification does not replace these interface checks. Do not force an unmatched coupling or alter the hydraulic lines to compensate for an incorrectly selected pump.

Product Images and Reference Identification

The image set includes the Olive Branch product-pack photograph and two different supplier catalogue views showing the shaft/flange and assembled pump. External reference photographs retain their original supplier markings. Confirm the appearance and configuration of the actual supplied unit during quotation; reference photos are provided for identification.

Request a 11C0353 CLG862 Steering Pump Quotation

For a 11C0353 hydraulic pump, LiuGong CLG862 steering pump or P257/P124 tandem gear pump enquiry, send the old nameplate, loader serial number and clear shaft, flange and port photographs. Include the quantity, required delivery destination and whether you need the complete pump or a service seal kit. The SP129157 seal-kit search reference describes a different ordering item.

Technical Reference Notes

Identification is based on the LiuGong CLG862 parts catalogue and operating manual, the Permco 257 technical brochure, and supplier catalogue references from Guangxi Linqian and Jinan Union. Brand and equipment names identify compatibility references. Olive Branch Hydraulics supply should be specified as aftermarket unless the quotation explicitly documents a different origin.
