The best specialty gear tools for removing and installing gears in a driveshaft include: 1. **Gear Pullers**: These are essential for removing gears from a driveshaft. They come in two-jaw or three-jaw configurations and can be adjusted to fit various gear sizes. Hydraulic gear pullers offer more power and ease of use for stubborn gears. 2. **Bearing Splitters**: Used in conjunction with gear pullers, bearing splitters help to grip gears with limited clearance. They provide a secure grip on the gear, allowing for safe removal without damaging the gear or shaft. 3. **Presses**: Hydraulic or mechanical presses are used to install gears onto a driveshaft. They provide controlled force to press the gear onto the shaft without causing damage. A press with a gauge is preferable for monitoring the applied force. 4. **Gear and Bearing Installers**: These tools are designed to evenly distribute force when installing gears, ensuring they are seated properly on the shaft. They often come with interchangeable sleeves to accommodate different gear sizes. 5. **Snap Ring Pliers**: These are necessary for removing and installing snap rings that may hold gears in place on a driveshaft. They come in various sizes and configurations, including straight, angled, and interchangeable tips. 6. **Torque Wrench**: Ensures that gears are installed with the correct torque specifications, preventing over-tightening or under-tightening, which can lead to gear failure. 7. **Dial Indicator**: Used to measure gear backlash and ensure proper alignment during installation. It helps in achieving precise gear positioning. 8. **Soft-faced Hammer**: Useful for gently tapping gears into place without causing damage to the gear teeth or shaft. These tools are essential for ensuring the safe and efficient removal and installation of gears on a driveshaft, minimizing the risk of damage and ensuring optimal performance.

To use a gear puller to remove stuck gears, follow these steps: 1. **Select the Right Gear Puller**: Choose a gear puller that fits the size of the gear. Pullers come in two-jaw or three-jaw designs; three-jaw pullers provide more stability. 2. **Prepare the Area**: Ensure the machinery is turned off and secured. Clean the area around the gear to remove any debris or grease. 3. **Position the Puller**: Place the jaws of the puller around the gear. Ensure the jaws are evenly spaced and securely grip the gear. The center bolt of the puller should align with the shaft or the center of the gear. 4. **Tighten the Center Bolt**: Use a wrench or socket to slowly tighten the center bolt of the puller. This action will pull the gear away from the shaft. Apply even pressure to avoid damaging the gear or the shaft. 5. **Apply Penetrating Oil (if necessary)**: If the gear is particularly stuck, apply penetrating oil to the shaft and gear interface. Allow it to sit for a few minutes to loosen any rust or corrosion. 6. **Continue Tightening**: Gradually continue tightening the center bolt. If the gear does not move, gently tap the puller with a hammer to help break the gear free. 7. **Remove the Gear**: Once the gear starts to move, continue tightening until the gear is completely removed from the shaft. 8. **Inspect and Clean**: After removal, inspect the gear and shaft for damage. Clean any remaining debris or oil. 9. **Store the Puller**: Clean and store the gear puller properly for future use. Always wear safety gear and follow manufacturer instructions for both the gear puller and the machinery.

Common types of gear pullers include: 1. **Two-Jaw Pullers**: These have two arms or jaws that grip the gear or bearing from opposite sides. They are adjustable and suitable for smaller gears or bearings. 2. **Three-Jaw Pullers**: Featuring three arms, these pullers provide a more balanced grip, making them ideal for larger gears or bearings. They distribute force evenly, reducing the risk of damage. 3. **Hydraulic Pullers**: These use hydraulic force to remove gears, bearings, or pulleys. They are powerful and efficient, suitable for heavy-duty applications where manual pullers might struggle. 4. **Slide Hammer Pullers**: These pullers use a sliding weight to generate impact force, effectively removing tightly fitted gears or bearings. They are useful in situations where space is limited. 5. **Internal Pullers**: Designed to grip the inside of a gear or bearing, these pullers are used when external gripping is not possible. They expand inside the component to provide a secure hold. 6. **External Pullers**: These grip the outside of the gear or bearing. They are the most common type and are used when there is enough space around the component. 7. **Bearing Splitters**: These are used in conjunction with pullers to remove bearings or gears that are flush with a surface. They provide a secure grip by fitting behind the component. 8. **Specialty Pullers**: Designed for specific applications, such as steering wheel pullers or harmonic balancer pullers, these are tailored for particular tasks. Each type of gear puller is designed for specific applications, and the choice depends on the size, location, and type of gear or bearing being removed.

To choose the right gear tool for tight spaces, consider the following factors: 1. **Size and Compactness**: Opt for tools specifically designed for tight spaces, such as stubby screwdrivers, mini ratchets, or compact wrenches. These tools are shorter and can fit into confined areas more easily. 2. **Flexibility and Articulation**: Look for tools with flexible heads or articulated joints, like flexible socket extensions or swivel-head ratchets, which allow you to maneuver around obstacles and reach fasteners at awkward angles. 3. **Tool Type**: Select the appropriate type of tool for the task. For example, a ratcheting wrench can be more effective than a standard wrench in tight spaces because it requires less movement to turn fasteners. 4. **Drive Size**: Smaller drive sizes, such as 1/4-inch drive ratchets, are better suited for tight spaces compared to larger drives, as they provide more control and require less clearance. 5. **Length and Reach**: Consider the length of the tool. Longer tools can reach deeper into tight spaces, but ensure they are not too long to handle comfortably. 6. **Grip and Control**: Ensure the tool has a comfortable grip that allows for precise control, even in awkward positions. Ergonomic handles can reduce hand fatigue during extended use. 7. **Material and Durability**: Choose tools made from durable materials like chrome vanadium steel, which can withstand the stress of working in confined areas without breaking or wearing out quickly. 8. **Special Features**: Some tools come with special features like magnetic tips or built-in lights, which can be beneficial in tight, dark spaces. 9. **Brand and Quality**: Invest in reputable brands known for quality and reliability, as they are more likely to offer tools that perform well in challenging conditions. 10. **User Reviews and Recommendations**: Check reviews and seek recommendations from professionals who frequently work in tight spaces to find tools that have proven effective.

Yes, gear tools can be used on rusted or seized gears, but with caution and proper technique. Rusted or seized gears often require additional steps to ensure safe and effective removal or repair. 1. **Assessment**: First, assess the extent of rust or seizure. Light surface rust might only need minimal intervention, while heavily rusted or seized gears may require more intensive treatment. 2. **Lubrication**: Apply a penetrating oil or rust remover to the affected area. Products like WD-40 or PB Blaster can help loosen rust and make the gears easier to work with. Allow the lubricant to penetrate for several hours or overnight for best results. 3. **Manual Tools**: Use manual gear pullers or wrenches to gently attempt to move the gears. Apply steady pressure to avoid breaking or damaging the gear teeth. If the gear is still stuck, do not force it, as this can cause further damage. 4. **Heat Application**: In some cases, applying heat to the gear can expand the metal slightly, breaking the rust bond. Use a heat gun or torch carefully, ensuring not to overheat and damage the gear or surrounding components. 5. **Mechanical Tools**: If manual methods fail, consider using mechanical tools like impact wrenches or hydraulic pullers. These tools provide more force but should be used with caution to prevent damage. 6. **Cleaning and Repair**: Once the gear is removed, clean it thoroughly to remove rust. Use wire brushes or sandpaper for surface rust. Inspect for any damage and repair or replace the gear if necessary. 7. **Prevention**: To prevent future rusting or seizing, regularly lubricate gears and store them in a dry environment. Using gear tools on rusted or seized gears is possible, but it requires patience, the right tools, and careful handling to avoid further damage.
