BG 103-315

Frequently Asked Questions

Q: What is the BG 103-315 and what function does it serve in a pallet jack?
A: The BG 103-315 is an OEM hydraulic pump piston for Blue Giant manual pallet jacks. It is a critical component inside the hydraulic pump assembly that converts handle pressure into lifting force. When the handle is pumped, the piston creates hydraulic pressure to raise the load.

Q: Which Blue Giant pallet jack models use the BG 103-315 piston?
A: The BG 103-315 is designed for Blue Giant PT-50 and PT-55 manual pallet jacks. Verify your equipment model number matches either PT-50, PT 50, PT-55, or PT 55 before ordering.

Q: What material is the BG 103-315 piston made from?
A: The BG 103-315 is engineered from hardened steel and features a machined surface with a corrosion-inhibitor coating. Hardened steel provides the strength and wear resistance required to withstand repeated hydraulic pressure cycles and maintain a tight seal with the pump cylinder.

Q: What does the corrosion-inhibitor coating do?
A: The corrosion-inhibitor coating protects the hardened steel piston from rust and oxidation caused by humidity, hydraulic fluid exposure, and warehouse environments. This coating extends the service life of the piston and maintains the integrity of the hydraulic seal.

Q: Are there cross-reference or equivalent part numbers for the BG 103-315?
A: The BG 103-315 is the OEM part designation for Blue Giant PT-50 and PT-55 hydraulic pump pistons. Always order by the exact part number BG 103-315 to ensure you receive the correct OEM-specification component.

Q: What symptoms indicate the hydraulic pump piston needs replacement?
A: Signs of a failing piston include weak or slow lifting, loss of hydraulic pressure, visible hydraulic fluid leaking from the pump, or handle resistance that feels different than normal. If the jack no longer lifts smoothly or holds load, the piston may need replacement. Have the pump inspected by a qualified technician.
