LF 20250B

Frequently Asked Questions

Q: What is the LF 20250B and what equipment does it fit?
A: The LF 20250B is a pump piston washer designed as a replacement component for Lift-Rite model 6600 manual pallet jacks. This washer is part of the internal hydraulic pump assembly and ensures proper piston sealing during pump operation.

Q: What is the function of this pump piston washer in the hydraulic system?
A: The LF 20250B washer sits against the piston and provides a sealing surface within the hydraulic pump. It helps maintain hydraulic pressure by reducing internal leakage past the piston during pump strokes. Proper contact between the washer and pump bore is critical for pump efficiency.

Q: Will the LF 20250B fit model L-55 or other Lift-Rite manual pallet jacks?
A: No. The LF 20250B is engineered for the Lift-Rite model 6600 only. Do not substitute this part on L-55 or other Lift-Rite models, as pump internal dimensions vary between models and incorrect washers will not seal properly, causing loss of pressure.

Q: What material is the LF 20250B washer made from?
A: The LF 20250B is manufactured to OEM specifications using materials designed to withstand repeated compression and movement within the hydraulic pump. The washer is engineered for durability in manual pump applications and maintains its sealing properties under normal warehouse operating conditions.

Q: When should the LF 20250B washer be replaced?
A: Replace the LF 20250B if your model 6600 pallet jack shows signs of pump failure such as slow or no platform rise, excessive pump effort, or reduced holding pressure. A worn washer cannot maintain hydraulic seal integrity. The washer may also be replaced during pump overhaul or when servicing other internal pump components.
