Frequently Asked Questions
Q: What is the ML A327 wiper and what does it do?
A: The ML A327 is a wiper seal component in the hydraulic pump assembly. It removes contaminants and debris from the piston rod, protecting the pump from external contamination.
Q: Which pallet jacks use the ML A327 wiper?
A: The ML A327 fits Mighty Lift ML55 and ML55L manual pallet jack models. This includes alternate model designations ML55-II, ML55II, and ML55 II with matching L variants.
Q: Why is a wiper seal important in pallet jack pumps?
A: The wiper prevents dirt, moisture, and particulates from entering the pump cylinder and contaminating the hydraulic fluid. A degraded wiper accelerates seal wear and system failure.
Q: When should the ML A327 wiper be replaced?
A: Replace the ML A327 if the rod extends with visible dirt accumulation, if the pump makes grinding noises during operation, or during standard pump maintenance. Wipers typically require replacement before primary seals fail.
Q: Is the ML A327 wiper included in pump seal kits?
A: The ML A327 wiper is typically sold as an individual component for replacement or repair. Check your pump seal kit contents to confirm inclusion before ordering.
