Removing the housing from a Generator is a necessary step for maintenance, repair, and inspection. Proper removal prevents damage to internal components and ensures safety during the process.
Managers overseeing maintenance teams need to understand the correct process. This helps you avoid unnecessary downtime and costly mistakes.
This guide explains how to safely remove generator housing from a generator, the tools required, and solutions to common challenges.
Tools and Safety Precautions
Tools you’ll need:
- Wrench set
- Screwdrivers
- Dead blow hammer
- Block of wood
- Drill (for riveted housings)
- Protective gloves and eyewear
Safety Steps Before Starting
- Disconnect the generator from all power sources.
- Allow the unit to cool if recently in use.
- Place the generator on a stable surface to prevent sliding.
- Wear protective gloves and safety glasses to avoid injury.
- Keep all tools within reach for a smooth workflow.
Step-by-Step Guide to Removing Generator Housing
Step 1: Accessing the Housing
- Identify all fasteners securing the housing. These may include bolts, screws, or rivets.
- Remove the fasteners using the appropriate tool.
- Then, check for hidden fasteners, especially in corners or beneath insulation.
- If the housing is riveted, use a drill to remove the rivets carefully.
- Disconnect any wires attached to the housing before you remove it.
Step 2: Removing the Stator and Rotor
- Unbolt and carefully remove the stator from the engine.
- Loosen, but do not completely remove, the rotor through-bolt. This bolt runs through the rotor into the crankshaft.
- Position a block of wood against the rotor and use a dead blow hammer to tap it free.
- Rotate the rotor slightly and repeat tapping on different sides until it separates.
- Next, fully remove the through-bolt and carefully pull the rotor off.
Step 3: Handling Riveted Housings
- Drill out the rivets without damaging surrounding metal.
- Look for hidden rivets under insulation or tape and remove them.
- Use a punch tool to push out any stubborn rivets.
- Once you remove all the rivets, slide the housing free from its base.
Step 4: Lifting and Removing the Housing
- Shift the housing side to side to break free any stuck areas.
- Lift it off carefully. Make sure no remaining fasteners or wires connect.
- Place the housing on a stable surface for inspection or repairs.
Troubleshooting Common Issues
Housing Won’t Budge?
- Double-check for any remaining screws or rivets.
- Apply penetrating oil to loosen rusted fasteners.
- Use a rubber mallet to tap around the edges and release the housing.
Rotor Stuck to the Engine Shaft?
- Install a grease fitting on the end of the rotor and use a grease gun to apply pressure.
- Tap the rotor at different angles with a block of wood and hammer.
- Apply heat to expand the metal and ease separation.
Damage Prevention Tips
- Do not strike the rotor with a steel hammer, as this can cause damage.
- Avoid hitting the copper windings or slip rings.
- Use wood or rubber barriers when applying force to components.
Final Steps and Reassembly Tips
- Inspect all parts for wear or damage before reassembly.
- Clean surfaces and apply lubricant where needed.
- Reattach components in reverse order, ensuring proper alignment.
- Secure all fasteners tightly to prevent movement during operation.
- Test the generator before full operation to confirm proper function.
