Safety Precautions
Before you start disassembling your Echo 58 V battery motor, there are a few safety precautions you should take to ensure you don’t get hurt:
-
Disconnect the spark plug wire
Remove the spark plug wire from the spark plug using a spark plug wrench. This will prevent the engine from starting while you are disassembling it.
-
Drain the fuel and oil
Drain the fuel and oil from the engine using a siphon or a drain plug. This will prevent spills and make the engine lighter to work on.
Place a container underneath the engine to catch the draining fuel and oil.
Locate the fuel and oil drain plugs on the bottom of the engine.
Use a wrench to loosen the drain plugs.
Allow the fuel and oil to drain completely.
Retighten the drain plugs once the fuel and oil have drained.
-
Use safety glasses
Wear safety glasses to protect your eyes from flying debris or sawdust when you are drilling or cutting.

Locating the Motor Housing
Identifying the motor housing of your Echo 58 Voly Motor is crucial for proper disassembly. Here’s a detailed guide to locate it accurately:
1. Remove the Lower Housing
Begin by detaching the lower housing from the motor body. This usually involves removing a few screws located at the bottom of the motor.
2. Locate the Upper Housing
Once the lower housing is removed, you’ll have access to the upper housing. It typically consists of a plastic or metal enclosure that covers the top of the motor.
3. Identify the Motor Housing
| Characteristic | Description |
|---|---|
| Position | Located inside the upper housing, usually in the center |
| Shape | Typically cylindrical or rectangular, often with cooling fins |
| Size | Varies depending on the motor, but generally the largest component within the upper housing |
| Color | Usually black or silver |
| Markings | May have markings or labels indicating the motor model or specifications |
To confirm the identification, gently tap the suspected motor housing with a wrench or screwdriver. A metallic sound indicates the presence of the motor assembly.
Removing the Top Cap
1. Position the motor upside down on a stable surface.
2. Locate the top cap, which is the round, plastic cover at the top of the motor.
3. Use a Phillips screwdriver to remove the four screws securing the top cap.
4. Carefully lift the top cap off the motor. Note that the top cap may be attached to the wires leading to the motor. If so, be careful not to pull the wires excessively.
Disassembling the Rotor Assembly
To disassemble the rotor assembly, follow these steps:
5. Inspecting the Rotor Assembly
Once the rotor assembly is disassembled, inspect it carefully for any signs of damage or wear. Look for any cracks, nicks, or other defects in the rotor windings or the commutator. Also, check the bearings for any signs of wear or play. If you find any damage, replace the affected components before reassembling the motor.
The following table summarizes the key components of the rotor assembly and their functions:
| Component | Function |
|---|---|
| Rotor windings | Conduct electrical current to create a magnetic field that interacts with the stator windings to generate torque. |
| Commutator | Rectifies the electrical current to the rotor windings, ensuring that the correct direction of current is applied to each winding. |
| Bearings | Support the rotating shaft and reduce friction. |
Removing the Stator Housing
The stator housing is the outer casing of the motor that holds the stator windings. To remove the stator housing, you will need the following tools:
Once you have the necessary tools, you can follow these steps to remove the stator housing:
Replacing the Stator Housing
To replace the stator housing, simply follow the steps in reverse order. Be sure to tighten the screws that hold the stator housing in place securely.
Inspecting the Motor Components
Once you have disassembled the motor, it is important to inspect the components carefully to identify any potential problems. Here are a few key areas to check:
Rotor
The rotor is the rotating part of the motor that generates power. Inspect the rotor for any signs of damage, such as scratches, dents, or broken windings. You should also check the bearings that support the rotor to ensure they are not worn or damaged.
Stator
The stator is the stationary part of the motor that creates the magnetic field. Inspect the stator for any signs of damage, such as loose windings, burnt insulation, or broken laminations. You should also check the air gap between the rotor and stator to ensure it is within specifications.
Commutator
The commutator is a component that makes contact with the brushes and helps to convert AC power to DC power. Inspect the commutator for any signs of wear, such as burnt or pitted segments. You should also check the springs that hold the brushes in place to ensure they are not worn or broken.
Brushes
The brushes are components that make contact with the commutator and transfer electrical current to the rotor. Inspect the brushes for any signs of wear, such as worn or frayed bristles. You should also check the brush holders to ensure they are not worn or damaged.
Bearings
The bearings support the rotor and allow it to rotate smoothly. Inspect the bearings for any signs of wear, such as grinding, squealing, or excessive play. You should also check the lubrication of the bearings to ensure they are properly lubricated.
Electrical Connections
Inspect all of the electrical connections in the motor to ensure they are secure and free of corrosion. This includes checking the connections between the stator, rotor, brushes, and any other electrical components.
Reassembling the Rotor Assembly
To reassemble the rotor assembly, follow these steps:
Installing the Stator Housing
Before installing the stator housing, ensure the stator is correctly seated in the motor housing and all the screws are in place securely.
Locate the stator housing, which is typically a large, cylindrical component. Align the stator housing with the motor housing, ensuring the mounting holes on both components match up.
Insert the mounting bolts into the holes and tighten them securely using a wrench or screwdriver. Ensure the stator housing is seated flush against the motor housing and there are no gaps between them.
Once the stator housing is securely mounted, proceed with the remaining assembly steps to complete the disassembly process.
Additional Details for the Installation of the Stator Housing
Closing the Motor Housing
1. Turn the echo motor over so that the stator is facing up.
2. Place the rubber o-ring into the groove on the motor housing.
3. Align the two halves of the motor housing and press them together.
4. Insert the four screws into the holes on the motor housing and tighten them.
5. Install the blade onto the motor shaft and tighten the nut.
6. Connect the spark plug wire to the spark plug.
7. Attach the battery to the motor.
8. Turn the echo motor over and place it in the case.
9. Secure the case with the screws.
10. Your echo motor is now reassembled and ready to use.
