RL 3-27059

Frequently Asked Questions

Q: What is the function of the RL 3-27059 plunger?
A: The plunger is a critical hydraulic component that regulates pressure and controls the raise/lower cycle on manual pallet jacks. It moves in response to pump action and directs hydraulic fluid flow.

Q: Which Rol-Lift pallet jack models use this plunger?
A: The RL 3-27059 plunger is compatible with Rol Lift manual pallet jacks that use the standard plunger assembly. Verify your equipment pump configuration matches this part number before ordering.

Q: What material is this plunger made from?
A: The plunger is manufactured from hardened steel or high-strength alloy steel to withstand repeated pressure cycling and resist wear from hydraulic fluid contact and pump sleeve friction.

Q: How do you know when this plunger needs replacement?
A: Replace the plunger if the jack loses pressure during hold, requires excessive pumping to raise loads, leaks hydraulic fluid around the pump, or the handle feels spongy with no resistance. These symptoms indicate plunger seals or the plunger itself is worn.

Q: What is the lifespan of a plunger assembly?
A: Under normal use, plungers last 4 to 7 years. Lifespan depends on usage frequency, hydraulic fluid condition, and contamination. Poor maintenance or dirty fluid shortens lifespan significantly.
