27843260

Frequently Asked Questions

Q: What does the 27843260 hydraulic plunger assembly do?
A: The 27843260 is a replacement hydraulic plunger assembly for manual pallet jack pumps. It converts manual handle force into hydraulic pressure that lifts the load. A worn or damaged plunger reduces lift performance and causes pump failure.

Q: Which manual pallet jacks is the 27843260 plunger assembly compatible with?
A: The 27843260 fits standard manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers with similar pump designs. Verify your pallet jack model and pump serial range for compatibility.

Q: What are the symptoms of a failed plunger assembly?
A: Signs of plunger failure include loss of lifting pressure, inability to raise load fully, visible leakage from pump, spongy pump handle action, or complete loss of lift. These indicate the plunger seal has failed or the plunger is scored.

Q: What material is the 27843260 plunger assembly made from?
A: The 27843260 features precision-machined steel construction designed to OEM fitment and durability standards. Steel provides resistance to wear from repeated pump cycles and maintains tight tolerances for pressure sealing.

Q: How long does a hydraulic plunger assembly typically last?
A: Plunger life depends on pump frequency and maintenance. With regular use and oil changes every 1 to 2 years, expect 3 to 5 years of service. Poor maintenance or continuous heavy use reduces lifespan significantly.

Q: Is the 27843260 compatible with standard seal kits?
A: Yes, the 27843260 plunger assembly is compatible with standard hydraulic seal kits for manual pallet jack pumps. Always replace seals when installing a new or rebuilt plunger to ensure a proper pressure seal.
