Frequently Asked Questions
Q: Which Uline pallet jack models are compatible with the H-1043-B147 piston assembly?
A: The H-1043-B147 hydraulic pump piston assembly fits Uline models H-1043, H-1193, H-1366, H-1484, and H-1491. Verify your equipment model before ordering to confirm compatibility.
Q: What is the cross-reference part number for the H-1043-B147?
A: The H-1043-B147 has a documented cross-reference part number of H-1366-B147. Both part numbers refer to the same hydraulic pump piston assembly component.
Q: What function does the H-1043-B147 piston assembly serve?
A: The H-1043-B147 is the reciprocating piston component in the hydraulic pump assembly, positioned as item 31. It interfaces directly with the cylinder cap, seal system, and spring assembly to create the pumping action that generates hydraulic pressure for manual lifting operations.
Q: Is the H-1043-B147 part of a larger hydraulic assembly?
A: Yes. The H-1043-B147 is a critical component of pump assembly H-1043PUMP and is included in the complete hydraulic unit H-1043BP100. This part should be ordered only when performing repair or replacement of pump subassembly components.
Q: What material is the H-1043-B147 piston manufactured from?
A: Specific material composition and detailed manufacturing specifications for the H-1043-B147 are not published in available documentation. Contact the parts department for material specification details if required for your application.
Q: Can the H-1043-B147 be used as a replacement in non-Uline equipment?
A: The H-1043-B147 is designed exclusively for Uline hydraulic pump assemblies. Cross-compatibility with other manufacturers such as Crown, Toyota, or Raymond cannot be confirmed without detailed dimensional and specification matching.
