Frequently Asked Questions
Q: What does the LF 20250 pump piston kit include?
A: The LF 20250 pump piston kit features a chrome-plated carbon steel piston body combined with nitrile rubber (NBR) hydraulic seals. The piston diameter is 1.25 inches with a 2.50 inch stroke length and accepts a 3/4-16 UNF hydraulic port thread.
Q: Which Lift-Rite models is the LF 20250 compatible with?
A: The LF 20250 is compatible with Lift-Rite model L-55 (alternate designations L55 and L 55). Related configurations include L50, LF50 Low Profile 4-way, and LR2055 models. Verify your jack model matches before ordering.
Q: What are the material specifications for the LF 20250?
A: The piston is chrome-plated carbon steel, providing corrosion resistance and wear durability. Seals are nitrile rubber (NBR), formulated for compatibility with standard hydraulic oils used in manual pallet jack systems.
Q: Does the LF 20250 require a separate seal kit?
A: Yes, the LF 20250 pump piston kit works with seal kit PL-20278 for complete overhaul. The PL-20278 is the referenced seal kit for LR2055 and L50 pump piston replacements.
Q: When should the LF 20250 pump piston be replaced?
A: Replace the LF 20250 if the jack fails to lift full load, descends under load without pump operation, produces weak pump handle resistance, or if hydraulic fluid leaks from the pump cylinder head during operation.
Q: What is the piston stroke capacity of the LF 20250?
A: The LF 20250 piston has a nominal 2.50 inch stroke length with a 1.25 inch diameter, calibrated for Lift-Rite L-55 manual pump hydraulic specifications. This displacement provides standard lift volume for L-55 load wheel raise operations.
