Frequently Asked Questions
Q: What does the AT PT2748W-84 overload valve kit do?
A: The AT PT2748W-84 is a pressure relief valve assembly that protects the hydraulic pump and cylinder from over-pressurization. It vents excess pressure when the system exceeds the set threshold, preventing damage to seals, hoses, and pump components. The adjustable design allows pressure limiting within a specified range for the PT2748W pump.
Q: Which pallet jack models does the AT PT2748W-84 fit?
A: This overload valve kit is an OEM replacement for Atlas EZ Lift and Jet W Series manual pallet jacks with PT2748W, PT-2748W, and PT2748W84 hydraulic pump units. Cross-reference equivalent part number JT PT2748W-84 (Jet W Series). Verify your pump assembly model before ordering to confirm compatibility.
Q: What symptoms indicate the overload valve needs replacement?
A: Replace the AT PT2748W-84 if you notice uncontrolled pressure (extreme resistance when lifting under normal loads), inability to achieve full lift height, hydraulic fluid leaking from pump housing joints, or if the lift operates at inconsistent pressure. These symptoms suggest the valve seal is degraded or the valve seat is damaged and cannot hold pressure.
Q: What parts are included in the AT PT2748W-84 kit?
A: The kit includes the complete overload pressure relief valve assembly with all internal valve components and seal components required for direct installation into OEM pump housings. All necessary internal parts for a full rebuild are included; no additional components are required for installation into the PT2748W pump.
Q: Is the AT PT2748W-84 an OEM Atlas part?
A: Yes, AT PT2748W-84 is the OEM Atlas part number for this valve kit. Manufacturer part number is ATPT2748W-84. The equivalent Jet W Series cross-reference is JT PT2748W-84. Confirm your pump OEM brand and model before ordering to ensure correct fitment.
