Saillong 3 Ton Dual-Pump Floor Jack Rebuild Kit — Large & Small Plungers with 17‑Piece Seal Kit

Saillong's 3 Ton Dual Pump Floor Jack Rebuild Kit supplies both large and small low-side pump plungers, cylinders, springs, and a 17-piece seal set to restore pumping power and stop hydraulic leaks. If your 3-ton dual-pump floor jack has lost lift height, feels spongy, or leaks oil, the root cause is often worn plungers and degraded seals. This all-in-one kit replaces the internal pumping components that control pressure and return action, letting you revive a trusted workshop jack without buying a new unit. Materials and seal compounds are chosen to resist wear and repeated high-pressure cycles typical in automotive use.

How will this rebuild kit improve my jack's performance?

Replacing both the small and large low-side plungers together with fresh seals restores proper hydraulic pressure and smoother pumping action. The new return springs and retainers ensure consistent rebound, reducing jerky movement and variable lift heights.

• Reestablishes sealing surfaces to stop oil bypass and pressure loss
• Smoother, more even pump strokes for consistent lift
• New springs improve return speed and stability under load

Which floor jacks are compatible with these parts?

The kit is designed for many popular 3-ton dual-pump floor jacks, including models from Pittsburgh, Torin Big Red, Arcan, and select Harbor Freight units. It is engineered to match common low-side pump dimensions, but you should compare the provided measurements with your original components to confirm fit.

• Check dimensions: small and large plunger/cylinder sizes included in product listing
• Compatible with common 3-ton dual-pump designs; not for Daytona 3-ton low-profile super duty
• Ideal for both home garage and shop repair projects

What exactly is included and how difficult is installation?

The package contains 17 pieces: two pump piston assemblies (large and small), two return springs, and 13 sealing and retaining components including O-rings, oil plugs, nylon stoppers, base pads, cap rings, and C-rings. Installation follows straightforward mechanical steps and can be completed with basic tools by anyone comfortable disassembling a floor jack.

• Stepwise install: remove old cylinder, insert packing and C-ring, grease parts, insert retainer, plunger, and spring
• Requires simple hand tools; no specialized hydraulic equipment needed
• Manual measurement tolerances noted — confirm sizes before starting

What are the key dimensions and material features I should know?

Dimensions are provided to help you verify compatibility: large plunger with seals 2.88" × 0.86", large cylinder 2.59" × 1.19"; small plunger with seals 2.88" × 0.59", small cylinder 2.64" × 1.06". Components are manufactured from durable metals and rubber compounds meant to withstand repeated high-pressure cycles and resist corrosion.

• Large plunger/cylinder and small plunger/cylinder dimensions listed for accurate match
• Heavy-duty metal plungers, springs, and corrosion-resistant retainers
• Seal kit uses pressure-rated rubber compounds for reliable sealing longevity

Who is this for: This Saillong rebuild kit is meant for mechanics, DIY enthusiasts, and fleet operators who want to repair and extend the service life of a 3-ton dual-pump floor jack rather than replace it. If you maintain a common brand jack like Pittsburgh, Big Red, Arcan, or a compatible Harbor Freight model and you notice leaks, reduced lift, or inconsistent pumping, this kit provides the internal parts needed for a cost-effective, professional-grade rebuild. Always verify the part dimensions and jack model compatibility before ordering to ensure a proper fit.
