Frequently Asked Questions
Q: What is BG 105-734 used for?
A: BG 105-734 is an OEM hardened steel check ball for Blue Giant manual pallet jack hydraulic units. It controls one-way hydraulic fluid flow, preventing backflow and maintaining system pressure during lifting and load holding.
Q: Which Blue Giant models use BG 105-734?
A: BG 105-734 fits Blue Giant manual pallet jack models PT-50 and PT-55 (alternate designations PT50, PT 50, PT55, PT 55). It is also compatible with hydraulic units ROI-5, ROI-55, and MTS 2000.
Q: What material is BG 105-734 made from?
A: BG 105-734 is manufactured from hardened steel, plain unfinished. The hardened steel construction provides the durability needed for high-pressure, high-cycle hydraulic duty. It is not plated or coated.
Q: What pressure ratings does BG 105-734 support?
A: BG 105-734 is engineered for the high-pressure hydraulic duty cycles of manual pallet jacks (typically 1500-3000 psi depending on load). It is rated for the full load capacity of PT-50 and PT-55 models. Do not exceed manufacturer load limits.
Q: What are symptoms of a failing BG 105-734?
A: Replace BG 105-734 if the jack drifts or slowly lowers under load, loses pressure between lifts, or makes unusual noise during pump operation. These symptoms indicate the check ball is not sealing properly. Failure to replace allows hydraulic fluid to bypass the valve.
Q: How long does BG 105-734 last?
A: Under standard duty, BG 105-734 lasts 5-10 years or longer. Lifespan depends on hydraulic fluid condition, contamination control, and duty cycle. Contaminated or degraded hydraulic fluid accelerates check ball wear. Maintain hydraulic fluid condition per manufacturer guidelines.
