Step 1: Safety First
Before beginning any repair work, safety should always be your top priority. Wear safety goggles and gloves to protect yourself from any debris and sharp edges.
Step 2: Disassemble the Tool
To access the motor pinion, you must carefully disassemble the tool.
Instructions:
- Remove the battery: Always start by removing the battery from the tool to avoid accidental activation.
- Unscrew the housing: Use your screwdriver to remove the screws holding the housing together. Keep them in a safe place for reassembly.
- Gently separate the housing: Carefully pull apart the housing to expose the internal components. Take your time to avoid damaging any clips or wires.
Step 3: Locate the Motor Pinion
Once you have the housing open, identify the motor assembly. The motor pinion should be visible at the front of the motor.
Step 4: Remove the Old Motor Pinion
With the motor now exposed, you can proceed to remove the old pinion.
Instructions:
- Use pliers: Grasp the motor pinion securely with your pliers.
- Gently twist and pull: Carefully twist and pull to dislodge it from the motor shaft. If it’s stuck, you may apply a small amount of lubricant to help it come off.
Step 5: Prepare for Installation of the New Pinion
Now that the old pinion is removed, it’s time to prepare for the installation of the new part.
Instructions:
- Clean the motor shaft: Use a cleaning cloth to remove any debris or old lubricant from the motor shaft.
- Lubricate the shaft: Apply a small amount of lubricant to the motor shaft to ease the installation of the new pinion.
Step 6: Install the New Motor Pinion
It’s time to install your new motor pinion (part number: 629151-02). Follow these steps carefully:
Instructions:
- Align the pinion: Position the new motor pinion over the motor shaft, ensuring it aligns properly with the gear teeth.
- Push down firmly: With a steady hand, push the new pinion onto the shaft until it’s fully seated. It may require some force but be gentle to not damage the new part.
Step 7: Reassemble the Tool
Once the new pinion is in place, it’s time to reassemble your DeWalt tool.
Instructions:
- Replace the housing: Align the two halves of the housing and press them together.
- Screw in the housing: Use your screwdriver to secure the screws back in place. Ensure all screws are tight but avoid over-tightening, which can strip the threads.
- Reinsert the battery: Once fully assembled, reinsert the battery to bring your tool back to life.
Step 8: Testing Your Rebuilt Tool
After reassembly, it’s essential to test your tool to ensure everything is functioning correctly.
Instructions:
- Power on the tool: Start the tool without any load to listen for any unusual noises.
- Perform a test cut or task: To thoroughly assess the rebuild, use the tool for a small project to see how it handles under load.
If everything operates smoothly, congratulations! You’ve successfully rebuilt your DeWalt 18V 629151-02 motor pinion.

What tools are needed to rebuild the DeWalt 18V 629151-02 Motor Pinion?
To successfully rebuild the DeWalt 18V 629151-02 Motor Pinion, you will need a few essential tools. These typically include a Phillips screwdriver, a flat-head screwdriver, a small wrench set, and pliers. A multimeter can also be useful to assess the motor’s performance once rebuilt. Additionally, having a heat gun or a soldering iron can be beneficial if you need to replace components that are soldered together.
Beyond these, it is advisable to have a work surface that can hold small parts securely, as you may be dealing with tiny screws and pins that could easily get lost. A magnetic tray or a container to hold these parts can prevent any mishaps during the rebuilding process. With the right tools at your disposal, the rebuilding task becomes much more manageable.
Can I rebuild the motor pinion myself, or should I hire a professional?
Rebuilding the motor pinion yourself is entirely possible if you have a basic understanding of electric motor mechanics and follow the instructions carefully. Many DIY enthusiasts take on such projects, and there are ample resources and tutorials available that guide you through the entire process step-by-step. If you enjoy hands-on work and have the necessary tools, rebuilding it yourself can be fulfilling and cost-effective.
However, if you are unsure about your skills or are not comfortable with disassembling the motor, it may be wise to consult a professional. Hiring someone who has experience with electric motors can save time and ensure that the job is done correctly, minimizing the risk of further damage. Ultimately, your decision should be based on your comfort level with mechanical tasks and your assessment of the complexity of the problem.
What common issues can arise when rebuilding the motor pinion?
When rebuilding the motor pinion, several common issues can surface, often stemming from the disassembly process. One frequent problem is losing small components, such as screws or washers, which can hinder reassembly. Additionally, applying too much force while disassembling the motor can damage fragile parts, leading to further complications in the rebuilding process. Keeping organized and being gentle with the assembly can help mitigate these issues.
Another issue that may arise involves faulty wiring or electrical connections. If wires are frayed or connections are loose, the motor may not function correctly after the rebuild. It’s crucial to inspect all wiring thoroughly and make necessary repairs before reassembly. Properly testing the motor with a multimeter can help identify potential electrical issues before causing further problems after the motor is put back together.
How do I know if the motor pinion needs replacement or just rebuilding?
Determining whether the motor pinion needs a complete replacement or just a rebuild involves examining its condition closely. Signs of wear, such as excessive grinding noises, overheating, or grinding during operation, can indicate that the pinion is damaged and may need to be replaced. Additionally, if you notice visible cracks or deformation of the pinion gear, a replacement is likely necessary.
If the motor operates but shows some performance issues, a rebuild may be sufficient. Cleaning the motor and lubricating moving parts can often resolve minor performance problems. Conducting a thorough inspection of the motor components and testing their functionality can guide you in making the right decision. If you’re still unsure, consulting a professional for their opinion can provide clarity on the best course of action.
Are there any specific safety precautions to take while rebuilding the motor pinion?
Yes, there are several important safety precautions to consider when rebuilding the motor pinion. It is crucial to begin by disconnecting the power supply from the tool to avoid any accidental starts while you are working on it. Wearing safety goggles can protect your eyes from any debris that may fly off during disassembly. Additionally, gloves are advisable as they can protect your hands from sharp edges and potential injuries.
Another safety measure includes working in a well-lit area free from distractions. This allows for better visibility and minimizes the risk of accidents. Always ensure you are using tools that are in good condition to prevent slip-ups that could lead to injury. Lastly, if you’re unfamiliar with electric motors or the tools involved, take your time to read the instructions before starting and don’t hesitate to seek guidance when needed.
What should I do if the rebuilt motor pinion doesn’t work as expected?
If the rebuilt motor pinion doesn’t work as expected, the first step is to conduct a thorough diagnose of the assembly. Check for any loose connections, improperly aligned parts, or missing components. Sometimes, a minor oversight such as a misplaced screw can lead to malfunction. Rechecking each step you took during the rebuild process can help pinpoint where things might have gone wrong.
If everything appears to be assembled correctly, using a multimeter to check the electrical connections and motor windings can provide more insight into the problem. If the motor is drawing power but not functioning correctly, you may have to consider whether the issue lies with the pinion itself or another motor component. In some cases, it may be necessary to disassemble and rebuild again or consult with a professional for further diagnosis and repair.
