Frequently Asked Questions
Q: What is the WW PM-43P plunger component?
A: The WW PM-43P is a plunger assembly for Dayton model 3KR84 manual pallet jack hydraulic pumps. It is the primary piston element that generates hydraulic pressure when you work the handle up and down.
Q: Will the WW PM-43P fit my manual pallet jack?
A: The WW PM-43P is engineered for Dayton model 3KR84 pallet jacks only. Cross-check your equipment model plate before ordering. Using an incorrect plunger can damage your hydraulic pump.
Q: What happens if the WW PM-43P plunger wears out?
A: A worn plunger creates internal leakage within the pump, resulting in slow lifting speed, inability to reach full height, loss of load holding, and reduced hydraulic pressure. Replacement is required to restore full functionality.
Q: What material is the WW PM-43P plunger made from?
A: The WW PM-43P plunger is precision-machined from hardened steel or cast iron, depending on the specific manufacturing batch. The plunger surface is honed smooth to maintain a seal against the pump cylinder bore.
Q: How long does the WW PM-43P plunger last before replacement?
A: With regular maintenance and proper hydraulic fluid cleanliness, the WW PM-43P plunger typically lasts several years of heavy use. Contaminated hydraulic fluid accelerates wear. Replace when you experience lifting performance loss or pressure drop.
