Replacement Selection for a Rexroth A10VO28 Hydraulic Pump on a Sandvik LH410
During maintenance of the hydraulic system on a Sandvik LH410 LHD loader, replacement of a worn Rexroth axial piston pump supplied under Sandvik OEM reference 56024635 became necessary. The objective was to identify a fully compatible replacement while preserving the original control configuration, drive interface and installation parameters. A technical assessment of the OEM specification was carried out and a replacement unit suitable for installation without equipment modifications was selected.
Identification Challenge and Procurement Risks
Within Sandvik documentation, the assembly is identified by OEM reference 56024635, while the hydraulic unit itself belongs to the Bosch Rexroth A10VO28 product family. Since the LH410 operates in demanding underground mining conditions, hydraulic system performance directly affects manoeuvrability, productivity and operational safety. Procurement of a standard catalogue version without verification of the original specification may result in installation issues, control incompatibilities or deviations in system performance.
Assessment of the OEM Specification
A detailed review of the available technical documentation and equipment data was carried out. Particular attention was given to the control configuration, shaft interface, mounting arrangement and hydraulic connections. The purpose of the assessment was to verify all parameters critical to installation and operation before selecting a replacement unit.
Selection of a Compatible Replacement
Based on the results of the technical assessment, a complete compatibility profile was established. Direction of rotation, installation geometry, hydraulic interfaces and operating characteristics were compared against OEM requirements. Following verification, a new Rexroth A10VO28 pump in a compatible configuration was selected as a replacement solution requiring no modifications to the equipment.
Installation and Operational Verification
The replacement pump was installed using the existing mounting arrangement and hydraulic connections of the Sandvik LH410. Standard commissioning procedures were completed, including filling the pump housing with hydraulic fluid and performing system checks. Subsequent functional testing confirmed stable hydraulic performance, predictable response of the hydraulic actuators and reliable operation of both steering and implement systems. The machine was returned to service without modifications to the hydraulic circuit or drive interfaces.
