Disassembling the Gearbox
Before diving into the disassembly process, ensure you have the necessary tools: a set of small screwdrivers (flat and Phillips head), needle-nose pliers, a pair of tweezers, and possibly a small pry tool. It’s also helpful to have a clean workspace and a container to keep screws and small parts organized. The gearbox is the heart of the drivetrain, and removing it requires careful attention to avoid damaging the plastic components. Start by locating the gearbox housing, typically found beneath the chassis of the RC military truck. The housing is usually secured with screws, so use the appropriate screwdriver to remove them. Be mindful of the screw sizes, as they may vary, and keep them organized for reassembly.
Once the screws are removed, gently pry the gearbox housing apart using a pry tool or a flat-head screwdriver. Apply even pressure to avoid cracking the plastic. Inside, you’ll find the gears, bearings, and possibly a motor or differential assembly. Take note of how the gears are aligned and meshed together, as this will be crucial for reassembly. Carefully lift the top half of the housing, ensuring no parts fall out. If the gears are held in place by clips or pins, use tweezers or needle-nose pliers to remove them gently.
Next, focus on removing the gears themselves. Start with the largest gear, often the one connected to the motor or differential. Depending on the design, it may be press-fit or secured with a small screw. If it’s press-fit, gently wiggle it free using a pair of pliers, taking care not to apply too much force. If it’s screwed in, remove the screw and lift the gear out. Repeat this process for the remaining gears, working from largest to smallest. Keep track of the order and orientation of each gear, as this will ensure proper reassembly.
After removing the gears, inspect the gearbox for any remaining components, such as bearings or shims. These are often seated in specific locations and may require gentle prying or twisting to remove. Use tweezers to extract them carefully, avoiding damage to the plastic housing. Once all components are removed, clean the gearbox housing and parts thoroughly to prepare for reassembly or replacement.
Finally, if your goal is to replace the plastic drivetrain with a metal one, take detailed notes or photos during disassembly to aid in the installation of the new components.

Removing the Motor and Pinion Gear
Before beginning the process of removing the motor and pinion gear from your RC military truck's plastic drivetrain, ensure you have the necessary tools: a set of hex drivers, a pair of needle-nose pliers, and possibly a small flathead screwdriver. Start by placing the truck on a stable surface and removing the body to access the internal components. Locate the motor, which is typically mounted near the center or rear of the chassis, connected to the drivetrain via a pinion gear. The pinion gear is a small, toothed wheel that meshes with the spur gear on the drivetrain. Familiarize yourself with these components before proceeding to avoid any confusion during disassembly.
To remove the motor, first disconnect the motor wires from the electronic speed controller (ESC). Gently pull the connectors apart, taking care not to damage the wires. Next, locate the screws securing the motor to the motor mount. These are usually two or three small screws accessible from the side or bottom of the mount. Use the appropriate hex driver to remove these screws, setting them aside in a safe place. Once the screws are removed, carefully lift the motor out of the mount, ensuring the pinion gear disengages from the spur gear smoothly. If the pinion gear is stuck, gently wiggle the motor side to side to free it.
With the motor removed, focus on extracting the pinion gear. The pinion gear is often press-fit onto the motor shaft and secured with a setscrew. Locate the setscrew on the side of the pinion gear and use a small hex driver to loosen it. Be cautious not to strip the screw, as it is typically small and delicate. Once the setscrew is loosened, use a pair of needle-nose pliers to grip the pinion gear and pull it straight off the motor shaft. If the gear is stubborn, gently tap the pliers handle with a small hammer to dislodge it. Avoid excessive force to prevent damaging the motor shaft.
After removing the pinion gear, inspect both the motor and the gear for wear or damage. If the pinion gear shows signs of excessive wear, such as stripped teeth or deformation, consider replacing it. Similarly, check the motor shaft for any burrs or damage that could affect future performance. If everything appears in good condition, set the components aside for reassembly or further maintenance. Ensure all screws and small parts are stored securely to avoid loss.
Finally, take this opportunity to clean the motor mount and surrounding area. Use a soft brush or compressed air to remove any dirt or debris that may have accumulated. Cleaning these areas will ensure smooth operation once the drivetrain is reassembled. With the motor and pinion gear successfully removed, you can now proceed to the next steps in disassembling or maintaining your RC military truck's drivetrain. Always work methodically and keep track of each component's orientation for easier reassembly.

Start by placing the truck on a stable work surface, ensuring it’s securely held in place to prevent any accidental movement. Locate the spur gear assembly, which is usually positioned near the center of the chassis, connected to the motor via a pinion gear. The spur gear is the larger gear with teeth that mesh with the pinion gear, driving the drivetrain.
Next, inspect the spur gear assembly for any screws or clips holding it in place. Most RC trucks secure the spur gear with a combination of screws and a gear cover. Use the appropriate hex driver to carefully remove the screws from the gear cover. Be gentle to avoid stripping the screws, as they are often small and delicate. Once the screws are removed, lift the gear cover off, exposing the spur gear and its mounting plate. If the cover is tight, use the needle-nose pliers to gently pry it loose, taking care not to damage any surrounding components.
With the gear cover removed, focus on the spur gear itself. The spur gear is typically mounted on a shaft or a bearing assembly. Depending on your truck’s design, you may need to remove a retaining clip or a small screw holding the gear in place. Use the needle-nose pliers to carefully remove any retaining clips, ensuring they are set aside for reassembly. If there’s a screw securing the gear, use the appropriate hex driver to loosen and remove it. Be cautious not to lose any small parts, such as washers or shims, that may be positioned beneath the gear.
Once the retaining clip or screw is removed, gently pull the spur gear off its shaft or bearing assembly. If the gear is tight, lightly wiggle it back and forth while pulling to free it without forcing it. Take note of the orientation of the gear and any spacers or bearings that come off with it, as these will need to be reinstalled correctly during reassembly. If the gear is particularly stubborn, avoid using excessive force, as this could damage the plastic components or the shaft.
Finally, inspect the area where the spur gear was mounted for any debris or wear. Clean the shaft or bearing assembly with a soft brush or compressed air to ensure smooth operation when the gear is reinstalled. With the spur gear assembly successfully detached, you can now proceed to the next steps of removing the rest of the plastic drivetrain or performing any necessary maintenance or upgrades. Always keep track of the removed parts and their positions to simplify the reassembly process.

Extracting the Drive Shafts
Begin by ensuring your RC military truck is securely placed on a stable surface, preferably with the wheels off the ground to allow free movement of the drive shafts. Locate the drive shafts, which are typically connected to the transmission at one end and the axles at the other. These shafts are responsible for transferring power from the motor to the wheels. Before proceeding, it’s essential to disconnect the battery to prevent accidental motor engagement during the removal process. Use a screwdriver or appropriate tool to remove any screws or clips securing the drive shaft covers or guards, exposing the shafts for easier access.
Next, focus on the universal joints (U-joints) that connect the drive shafts to the transmission and axles. These joints often have retaining clips or pins that hold them in place. Carefully pry out the retaining clips using a pair of needle-nose pliers or a small flathead screwdriver. If the U-joints have pins, gently tap them out using a punch and a hammer, ensuring not to damage the surrounding plastic components. Once the clips or pins are removed, the U-joints should be free to slide out of their housings, allowing you to separate the drive shafts from the transmission and axles.
With the U-joints disconnected, carefully pull the drive shafts out of their housings. Be mindful of any resistance, as there may be additional clips or seals holding the shafts in place. If the shafts are stuck, gently twist them back and forth while pulling to dislodge any debris or tight seals. Avoid forcing the shafts, as this could cause damage to the plastic drivetrain components. If necessary, use a small amount of lubricant around the shaft ends to ease removal.
After extracting the drive shafts, inspect them for wear, damage, or bent sections. If the shafts are in good condition and you’re simply removing them for maintenance or cleaning, set them aside in a safe place. If they need replacement, take note of their length, diameter, and any specific features to ensure you purchase the correct parts. Cleaning the drive shaft housings and U-joints at this stage is also recommended to remove dirt and grease buildup, ensuring smooth operation once reassembled.
Finally, if your RC truck has multiple drive shafts (e.g., front and rear), repeat the process for each shaft. Keep track of the orientation and position of each component, as drive shafts are often specific to their location in the drivetrain. Taking photos or notes during disassembly can be helpful for reassembly. Once all drive shafts are removed, you can proceed with further disassembly or maintenance of the plastic drivetrain components as needed.

Separating the Axles and Differentials
When separating the axles and differentials of your RC military truck's plastic drivetrain, begin by ensuring the vehicle is powered off and placed on a stable, flat surface. Gather the necessary tools, such as a screwdriver set (typically Phillips or flathead), pliers, and possibly a hex key, depending on your truck's design. Start by locating the screws or clips that secure the differential housing to the axle assembly. These are often found on the sides or top of the differential cover. Carefully remove these screws or disengage the clips, taking note of their positions for reassembly.
Next, gently pry or lift the differential housing away from the axle. Be cautious not to force it, as plastic components can be brittle. If the differential feels stuck, inspect for additional retaining clips or pins that may need to be removed. Once the housing is separated, you’ll typically find the differential gears and axle shafts exposed. Carefully lift the axle shafts out of the housing, ensuring you don’t damage the gears or bearings in the process. If the axles are press-fit or secured with C-clips, use a pair of pliers or a small pick tool to remove the clips and free the axles.
After removing the axles, focus on disassembling the differential itself. Most RC truck differentials consist of a gear set, cross pins, and side gears. Carefully remove the cross pins, which hold the side gears in place, using a small punch or pliers. Once the pins are out, the side gears and differential gears should be free to separate. Take note of the orientation of the gears to simplify reassembly. If your differential includes shims or spacers, keep track of their positions to maintain proper gear mesh.
If your RC truck has a locked or spool-type differential, the process may vary slightly. In this case, you’ll likely need to remove a locking plate or spool assembly after separating the housing. Use a screwdriver or hex key to remove any screws holding the plate in place, then carefully lift it out along with the spool. Again, be mindful of small components like shims or O-rings that may be present.
Finally, inspect all components for wear, damage, or debris before proceeding with further disassembly or maintenance. Clean the axles, differential gears, and housing thoroughly to ensure smooth operation once reassembled. Separating the axles and differentials is a delicate process, but with patience and attention to detail, you can successfully remove the plastic drivetrain components for repair or upgrading.
