Tools And Materials Needed
Rebuilding a Craftsman floor jack requires the right tools and materials. Having everything ready makes the process smooth and efficient. This section lists all essential items for a successful rebuild.
Essential Tools
Start with basic hand tools. A set of wrenches and screwdrivers is a must. Pliers help grip small parts firmly. A hammer may be needed for stubborn components. A socket set speeds up nut removal. Clean rags keep the parts free of dirt. A drain pan catches old hydraulic fluid safely.
Replacement Parts
Identify worn or broken parts first. Hydraulic seals often need replacement. The pump piston and release valve may wear out. Check the handle and lifting arm for damage. Use genuine Craftsman parts for best fit and durability. Keep new hydraulic oil ready for refill. A rebuild kit can include most needed parts.
Safety Gear
Protect yourself during the rebuild. Safety glasses shield your eyes from splashes and debris. Gloves protect hands from sharp edges and oil. Wear old clothes to avoid stains. Work in a well-ventilated area to avoid fumes. Keep a clean workspace to prevent accidents.

Preparing The Floor Jack
Preparing the floor jack is the first step to rebuilding it safely and correctly. This process ensures the jack works smoothly and lasts longer. Proper preparation helps spot any issues before starting the rebuild. Take your time and follow the steps carefully.
Start by cleaning the jack thoroughly. Dirt and old grease can hide problems. Cleaning also makes inspection easier. Next, drain the old hydraulic fluid. Fresh fluid improves performance and prevents damage. These steps set a solid base for the rebuild.
Cleaning And Inspection
Use a clean cloth to wipe off dirt and grease. A brush helps remove stubborn grime from tight spots. Clean every part you can reach. Check for cracks, rust, and worn components. Look closely at the lifting arm and wheels. Damaged parts must be fixed or replaced. This check prevents future breakdowns.
Draining Hydraulic Fluid
Place a container under the jack’s fluid reservoir. Open the drain valve or remove the fill plug carefully. Let all old fluid flow out. Dispose of old fluid safely according to local rules. Clean the reservoir with a cloth to remove residue. This step clears out dirt and old fluid before refilling.
Disassembling The Jack
Disassembling the Craftsman floor jack is the first step to rebuild it. This part needs care and attention to avoid damage. Start by working in a clean, well-lit space. Organize all parts as you remove them. This makes reassembly easier and faster.
Removing The Handle
Begin by taking off the handle. Locate the handle pin or bolt that holds it in place. Use the correct tool, such as a wrench or pliers, to remove it. Pull the handle straight out. Avoid twisting or bending the handle. Set the handle and pin aside carefully. These parts are essential for the jack’s operation.
Taking Apart The Hydraulic System
The hydraulic system is next. Release any pressure inside the jack by opening the release valve. Use a wrench to remove the hydraulic pump assembly. Be careful not to spill hydraulic fluid. Place a container underneath to catch any leaks. Remove the cylinder and piston parts with gentle force. Keep track of small seals and springs. These tiny parts can easily be lost but are vital for rebuilding the jack.

Replacing Worn Components
Replacing worn components is key to rebuilding a Craftsman floor jack. Old parts cause leaks and poor lifting power. New parts restore strength and safety. Focus on seals, O-rings, and the pump system. These parts wear out over time and need careful checking.
Seal Replacement
Seals keep hydraulic fluid inside the jack. Worn seals cause fluid leaks and loss of pressure. Remove old seals gently to avoid damage. Clean the area before installing new seals. Use the correct size and type for your model. Proper seal replacement stops leaks and improves jack performance.
O-rings And Gaskets
O-rings and gaskets also prevent leaks. They fit between parts to create a tight seal. Check for cracks or flattening in these rings. Replace any damaged or hardened O-rings and gaskets. Use lubricant to help fit new O-rings without tearing. Good seals keep the jack working smoothly.
Checking The Pump And Release Valve
The pump lifts the jack, and the release valve lowers it. Dirt or wear can block these parts. Test the pump by pumping the handle and watching lift speed. If slow, clean or replace the pump parts. Open and close the release valve to check smooth flow. Replace faulty valves to keep control over lifting and lowering.
Reassembling The Floor Jack
Reassembling the floor jack is a key step in the repair process. It brings all parts back together for smooth operation. Careful assembly prevents damage and ensures safety.
Follow each step slowly. Check parts for wear or dirt. Clean or replace parts as needed before putting them back.
Reinstalling Internal Parts
Start with the internal parts. Place the piston carefully inside the cylinder. Make sure it fits snugly without force.
Insert the springs and valves in their correct positions. These parts control the jack’s lifting power.
Check seals and O-rings. Replace any that look cracked or worn. This stops leaks and keeps pressure steady.
Use a small tool to guide tiny parts into place. Avoid dropping or losing any components during this step.
Securing External Components
Attach the handle to the pump lever. Tighten the screws or bolts firmly but do not over-tighten.
Reinstall the release valve. This part controls the jack’s lowering speed.
Fix the outer casing or cover. It protects the internal parts from dirt and damage.
Test the jack by pumping the handle. Look for smooth movement and no leaks before final use.
Refilling And Bleeding The Jack
Refilling and bleeding the Craftsman floor jack is a key step to keep it working smoothly. This process restores the hydraulic system to full strength. Proper fluid level and no air bubbles make the jack lift heavy loads safely and efficiently.
Hydraulic fluid moves pressure through the system. Air bubbles reduce this pressure and make the jack feel weak. Follow these steps carefully to refill and bleed the jack properly.
Adding Hydraulic Fluid
First, locate the fluid fill plug on the jack. Clean the area around it to stop dirt from entering. Remove the plug slowly. Use a clean funnel to pour the correct hydraulic fluid inside. Fill until the fluid level is just below the fill hole. Avoid overfilling, or the jack may leak. Replace the fill plug tightly to avoid spills.
Removing Air Bubbles
Air bubbles trap pressure and cause the jack to fail. Open the release valve fully to let air escape. Pump the handle slowly several times to push out trapped air. Watch for fluid leaking from the release valve. Close the valve when no more air or fluid escapes. Repeat pumping and releasing until the jack lifts smoothly and holds pressure. This ensures the jack works safely and reliably every time.
Testing And Adjustments
Testing and adjustments are key steps in rebuilding a Craftsman floor jack. They ensure the jack works safely and smoothly. After rebuilding, check every function carefully. Make small changes to pressure and lift height for best results.
Functionality Check
Start by inspecting the jack’s basic functions. Pump the handle and watch the lift rise smoothly. Lower the jack slowly to confirm controlled descent. Listen for any strange noises or leaks. Test the release valve to make sure it opens easily. Check for smooth movement without sticking or jerking.
Adjusting Pressure And Lift Height
Adjust the pressure to match the jack’s specifications. Use the pressure valve to increase or decrease force. Set the lift height by adjusting the release valve. Raise the jack to its full height and ensure it holds steady. Lower and lift a few times to confirm consistent performance. Fine-tune these settings until the jack feels stable and reliable.
Maintenance Tips For Longevity
Keeping your Craftsman floor jack in good shape helps it last longer and work safely. Simple care steps stop damage and wear. Follow these tips to keep your jack strong and ready for use.
Regular Cleaning
Clean the jack after every use. Wipe away dirt, dust, and grease. Use a cloth with mild soap and water. Avoid harsh chemicals that can damage parts. Dry the jack well to stop rust from forming.
Periodic Inspections
Check your jack often for signs of wear or damage. Look for cracks, leaks, or bent parts. Test the hydraulic system to ensure it lifts smoothly. Replace any worn or broken parts quickly. Regular checks keep your jack safe and reliable.
Proper Storage
Store the floor jack in a dry, clean place. Keep it away from moisture to prevent rust. Lower the jack fully before storing. Cover it with a cloth to block dust. Proper storage extends the life of your floor jack.
