Understanding Your Lawn Mower Starter
Before diving into the reassembly process, let’s familiarize ourselves with the key components of a typical lawn mower starter:
- Starter housing: This is the main outer casing that houses all the other parts.
- Armature: This is the rotating component that spins the motor shaft.
- Field coils: These electromagnetic coils generate the magnetic field that powers the armature.
- Brush holder: This assembly contains the brushes that conduct electricity to the armature.
- Starter drive gear: This gear engages with the flywheel on your lawnmower engine.
- Starter switch: This is the button you press to activate the starter.
Step-by-Step Guide to Reassembling Your Lawn Mower Starter
Now, let’s dive into the reassembly process. Remember to have your repair manual handy, as it will provide specific instructions for your particular model.
Step 1: Prepare Your Workspace
Ensure you have a clean, well-lit workspace to prevent any debris from entering the starter during reassembly. Gather all the necessary tools:
- Screwdrivers: Phillips and flathead screwdrivers are essential.
- Wrench: You might need a wrench for securing nuts and bolts.
- Pliers: These are useful for handling small parts.
Step 2: Inspect and Clean the Parts
Before reassembly, carefully inspect each component for damage or wear. Clean any debris or grease using a soft cloth and a mild cleaner.
Step 3: Reinstall the Brushes
The brushes are crucial for conducting electricity to the armature. Locate the brush holder assembly and install the new brushes, ensuring they are properly seated in their slots.
Step 4: Reinstall the Armature
The armature is the heart of the starter, and its alignment is essential. Carefully insert the armature shaft into the starter housing, ensuring it aligns correctly with the bearings.
Important Note: If your armature has a bearing on one end, be sure it seats properly in the housing before proceeding.
Step 5: Reinstall the Field Coils
Secure the field coils to the starter housing, making sure they are properly positioned and aligned with the armature.
Step 6: Reinstall the Starter Drive Gear
The starter drive gear engages with the flywheel on your engine. Align the gear with the shaft and secure it with the appropriate retaining nut.
Important Note: Make sure the gear is aligned correctly, otherwise, it will not engage properly with the flywheel.
Step 7: Reassemble the Starter Housing
Once all the internal components are in place, carefully reassemble the starter housing. Secure the screws and bolts, ensuring they are tight but not overtightened.
Step 8: Reconnect the Wires
Carefully connect the wires to the starter switch and other components. Refer to your repair manual for the correct wiring diagram.
Step 9: Test the Starter
Before installing the starter back on your lawnmower, test it to ensure it works properly. Connect a battery to the starter and press the switch. The armature should rotate smoothly without any binding or noise.
Step 10: Install the Starter
Once you are satisfied with the starter’s functionality, mount it back onto your lawnmower. Ensure it is securely fastened and the starter drive gear aligns with the flywheel.
Troubleshooting Common Problems
While reassembling your starter, you might encounter a few common problems:
The Starter Doesn’t Turn
- Check the battery connection: Ensure the battery terminals are securely connected.
- Check the starter switch: Ensure the switch is functional and properly connected.
- Inspect the armature: Verify the armature rotates freely without any binding.
