Step-by-Step Instructions for Rebuilding Your Dewalt 51844 Nail Gun
Now that you have your tools and parts ready, it’s time to start the rebuilding process. Be sure to follow these steps systematically for the best results.
Step 1: Safety First
Before starting any work, it is crucial to take safety precautions:
Warning: Always disconnect the nail gun from any power source or air supply before beginning any repairs or rebuilding tasks. Wear safety goggles and gloves to protect yourself from any flying debris or sharp edges.
Step 2: Disassembling the Nail Gun
Carefully disassemble your nail gun:
1. Remove the Housing
Start by unscrewing the screws holding the housing together. Ensure you place the screws in a safe location for easy reassembly later.
2. Take Out the Driver Blade
Once the housing is removed, you will have access to the driver blade. Gently pull out the driver blade; be cautious, as there might be springs or other components attached to it.
3. Inspect Each Part
Inspect the driver blade, trigger mechanism, and pneumatic components for any signs of damage or excessive wear. Make a note of any parts that require replacement, such as O-rings or the driver blade itself.
Step 3: Cleaning the Components
Cleaning is essential for a smooth operation:
1. Remove Debris
Using a soft brush or compressed air, clean any dirt, dust, or debris present in the nail gun’s components.
2. Lubricate Moving Parts
Apply a few drops of lubrication oil to the moving parts, including the driver blade and trigger mechanism. This will help in reducing friction, ensuring smooth operation.
Step 4: Replacing Damaged Parts
If you’ve identified any damaged parts during your inspection, it’s time to replace them:
Driver Blade Replacement
If the driver blade shows signs of excessive wear, it should be replaced. Remove any screws securing it, then install the new driver blade in the same position.
O-Ring Replacement
If the O-rings are worn or cracked, they must be replaced. Remove the old O-ring and replace it with a new one, ensuring it’s seated correctly.
Trigger Assembly Replacement
If the trigger mechanism is faulty, follow the specific instructions provided for its replacement, as it can vary based on the specific model.
Step 5: Reassembly
Now that your nail gun is clean and all necessary parts have been replaced, it’s time to reassemble:
1. Reinstall the Driver Blade
Carefully reinstall the driver blade into its original position. Make sure it moves freely and does not obstruct any other components.
2. Secure the Housing
Put the housing back on and secure it with the screws you removed earlier. Ensure that everything is aligned correctly and secure to prevent any future issues.
3. Conduct a Final Inspection
Before testing the nail gun, do a final inspection to ensure all components are correctly installed and secured.
Step 6: Testing Your Nail Gun
Once you’ve reassembled your nail gun, it’s time to test it:
1. Connect to Air Supply
Reconnect the nail gun to its air supply. Ensure there are no leaks by checking for any hissing sounds.
2. Test Firing
In a safe environment, conduct a test fire on scrap materials. Observe how the nail gun operates, paying attention to any unusual noises or failures to eject nails.
Common Problems and Solutions
Despite careful rebuilding, issues may still arise. Here are a few common problems and their potential solutions:
- Nail Jamming: This may occur due to debris or a malfunctioning driver blade. Regular cleaning and maintaining will help prevent jamming.
- Weak Firing: If nails are not driving in sufficiently, inspect the air supply or consider replacing the compression spring.

What tools do I need to rebuild my Dewalt 51844 nail gun?
To rebuild your Dewalt 51844 nail gun, you will need a variety of tools to ensure a smooth process. Essential tools include a screwdriver set (both flathead and Phillips), a set of wrenches, pliers, and possibly a hammer for certain adjustments. A workbench or a sturdy surface with good lighting will also be beneficial for assembling and disassembling the components safely.
Additionally, you may want to have some lubricant on hand to ensure that the moving parts function smoothly after the rebuild. A clean cloth or paper towels will be useful for wiping down the components and removing debris. Having these tools readily available will set you up for a successful rebuild of your nail gun.
How do I know if my nail gun needs rebuilding?
Signs that your Dewalt 51844 nail gun may need rebuilding include consistent misfires, a lack of power when firing nails, or the gun leaking air. If you notice that the gun isn’t driving nails flush or is struggling to penetrate the material, these are also indicators that internal components may be worn out. Regular maintenance can mitigate some issues over time, but if problems persist, a rebuild is likely necessary.
Another factor to consider is the age of the tool and its usage frequency. If your nail gun has been under heavy use for several years, it may naturally require a rebuild to restore its performance. It’s advisable to regularly inspect the tool and carry out preventative maintenance to help identify problems before they become serious.
Can I rebuild my nail gun, or should I seek professional help?
Rebuilding your Dewalt 51844 nail gun is certainly something you can do if you are comfortable with basic tools and following instructions. The process generally involves disassembling the tool, replacing or cleaning internal components, and reassembling it. Many DIY enthusiasts find this a manageable task, especially with the right guidance and resources, such as the step-by-step guide you have.
However, if you feel unsure about your ability to handle the rebuild or if you encounter complex issues beyond your expertise, it may be wise to seek professional help. Professionals have experience dealing with various problems and can ensure that the rebuild is completed correctly without further damage to the tool. Ultimately, the choice depends on your skill level and comfort with tackling mechanical repairs.
What are the common parts that need replacement during a rebuild?
During a rebuild of the Dewalt 51844 nail gun, some common parts that often require replacement include the O-rings, seals, and the firing mechanism. O-rings can wear out over time, leading to air leaks or inconsistent firing. Seals may also degrade, causing performance issues, and the firing mechanism is critical for the tool’s function, so any wear there can significantly impair usage.
You may also want to examine the piston assembly, driver blade, and springs for signs of wear. If any of these components are damaged or excessively worn, they should be replaced as part of the rebuild process. By addressing these key parts, you’ll help ensure that your nail gun performs optimally once you’ve completed the rebuild.
Are there specific maintenance steps I should take after rebuilding my nail gun?
Yes, maintaining your Dewalt 51844 nail gun after rebuilding is crucial for its longevity and performance. First, regularly clean your nail gun after each use to remove dust, debris, and any nail fragments that may have accumulated. Pay close attention to the magazine and firing mechanism, ensuring that they remain free of obstructions. Using compressed air can help clear hard-to-reach areas.
Additionally, lubrication is essential after a rebuild and should be performed periodically based on usage frequency. Use a light machine oil or the manufacturer-recommended lubricant to keep the moving parts functioning smoothly. Following the proper maintenance steps will help extend the life of your nail gun and keep it performing at its best.
What should I do if the nail gun still doesn’t work after rebuilding?
If your Dewalt 51844 nail gun doesn’t function properly after you’ve completed the rebuild, first take a deep breath and retrace your steps. Check to ensure that all components were reassembled correctly and that no parts were missed or improperly aligned. Refer to the guide you followed during the rebuild to verify that each step was executed accurately.
If everything appears to be in order and the tool still does not operate as expected, consider checking for external issues such as the air supply (if it is pneumatic) or the battery (if it is cordless). If troubleshooting doesn’t yield results, it may be best to consult a professional repair service for further diagnosis. Sometimes, problems can arise from deeper mechanical issues that require expertise beyond a standard rebuild.
