Frequently Asked Questions
Q: What is the JT PT2748A-025 ram piston?
A: The JT PT2748A-025 is the ram piston component for Jet manual pallet jack pump assemblies. It is located on the pump and is designed for units manufactured before serial number 704xxx. The ram piston is the moving component that generates hydraulic pressure during the lift cycle.
Q: Which Jet pallet jacks use the JT PT2748A-025 piston?
A: The JT PT2748A-025 is compatible with Jet Model A, L, and J series manual pallet jacks with model AJL designation and serial numbers below 704xxx. Locate your serial number on the pump to determine if this is the correct piston.
Q: How do I know which ram piston version my Jet pallet jack needs?
A: Check the serial number on your Jet pump assembly. If the serial number is below 704xxx, use the JT PT2748A-025. If your serial number is 704xxx or higher, use the updated JT PT2748A-025A. The wrong piston will not fit correctly and may cause seal leaks.
Q: What should I inspect when replacing this ram piston?
A: When replacing the JT PT2748A-025, inspect the pump bore for scoring, wear, or corrosion that could damage seals. Verify that all seal stack components (backup rings and O-rings) are present and undamaged. Any bore damage may require additional repairs beyond piston replacement.
