328.12031 Hydraulic Floor Jack Rebuild Seal Kit
The 59-piece rebuild kit is designed for Sears Craftsman 2 Ton floor jacks. It focuses on replacing essential seals to reduce leaks and restore pressure. Best for: DIYers with Sears Craftsman 2 Ton jacks who want an all-in-one seal solution. Caution: Verify compatibility with your exact model number before purchase to ensure correct seals.
MANUTEX Store 3 Ton Dual Pump Rebuild Kit
This kit targets 3-ton hydraulic floor jacks with dual pumps.

Best for: users with dual-pump jacks from brands like Pittsburgh, Harbor Freight, Daytona, or Torin. Why chosen: it restores hydraulic pressure and load capacity by addressing both pump plungers. Limitation: kit focuses on plungers, so you may need additional seals depending on your jack’s design.

This kit fits Sears, Craftsman, or MVP floor jacks rated around 3 tons or more, focusing on O-rings and related seals. Best for: users performing a mid-to-high-ton rebuild who need reliable O-rings to prevent slow leaks. Limitation: Ensure the kit’s seals match the exact jack model for a proper seal fitment.

Buying Guide: Key Considerations For Hydraulic Floor Jack Rebuild Kits
Choosing the right rebuild kit hinges on matching your jack’s tonnage, brand, and dual-pump configuration. Below are practical questions and guidance to help you compare options.
- Which tonnage does my floor jack support? Choose a kit that explicitly states compatible tonnage (1.5, 2, or 3 tons).
- Is my jack single-pump or dual-pump? If dual-pump, consider a kit that includes plungers for both pumps.
- What seals are included? Ensure the kit contains the necessary O-rings, rubber seals, and any required steel balls for your model.
- Does the kit specify Sears/Craftsman compatibility? Some kits are model-specific; verify model numbers in your user manual.
- Are replacement parts easy to install? Look for kits with straightforward parts fitment and clear component descriptions.
- What is the risk of leakage after rebuild? Seals must meet hydraulic pressure requirements to minimize future leaks.
Frequently Asked Questions
- Q: Do rebuild kits come with all seals required for a full rebuild? A: Most kits provide the essential seals for targeted leaks and pressure restoration, but verify the exact contents before purchase.
- Q: Can I mix parts from different brands? A: It’s best to use brand- or model-specific kits to ensure proper fit and function.
- Q: How do I know if I need a dual-pump kit? A: If your jack has two pump plungers, a dual-pump kit helps maintain hydraulic balance and pressure across both pumps.
- Q: Will a rebuild restore hydraulic lifting capacity? A: Replacing worn seals and plungers can restore pressure and lifting performance when components were degraded.
- Q: Are these kits reusable for multiple jacks? A: Some components are model-specific; check compatibility for each jack model before reuse.
- Q: Do these kits require professional installation? A: Basic rebuilds can be done by DIYers with basic tools, but consult a professional if unsure about hydraulic safety.
