Ремонт СТАРТЕРА от А до Я - замена Бендикса, Щеток, Втулок

Introduction

This tutorial will guide you through the process of repairing a starter motor, specifically focusing on replacing the Bendix, brushes, bushings, and bearings. This guide is particularly relevant for those working on a Bosch starter (1.4KW, model number 078 911 023 D) commonly found in Audi A6 C5 vehicles. Follow these steps to troubleshoot and fix common starter issues such as slipping Bendix that prevents the engine from starting.

Step 1: Gather Required Tools and Parts

Before beginning the repair, ensure you have the following tools and parts ready:

Tools

• Wrench set
• Screwdrivers (flathead and Phillips)
• Pliers
• Multimeter
• Clean cloths
• Lubricant

Parts

• Replacement Bendix
• New brushes
• New bushings
• New bearings (if necessary)

Step 2: Remove the Starter

To access the starter, you need to remove it from the vehicle:

1. Disconnect the battery to prevent any electrical shorts.
2. Locate the starter. It is typically mounted near the engine.
3. Use the wrench to remove the bolts holding the starter in place.
4. Carefully pull the starter out of its housing.

Step 3: Disassemble the Starter

Once the starter is removed, disassemble it to access the internal components:

1. Use a screwdriver to remove any screws holding the starter casing together.
2. Gently separate the casing to expose the internal parts, including the Bendix, brushes, and bushings.
3. Take note of the arrangement of parts as you disassemble them for easier reassembly.

Step 4: Inspect and Replace Components

Now, inspect the internal components for wear and damage:

1. Bendix:

   • Check for signs of wear or damage.
   • If it is slipping, replace it with a new one.

2. Brushes:

   • Inspect the brushes for wear. If they are worn down, replace them with new ones.

3. Bushings and Bearings:

   • Look for any signs of wear in the bushings and bearings.
   • Replace them if necessary.

Step 5: Reassemble the Starter

After replacing any damaged components, reassemble the starter:

1. Carefully place the new or repaired components back into the casing.
2. Ensure that everything is aligned correctly according to your notes from disassembly.
3. Secure the casing with screws.

Step 6: Reinstall the Starter

With the starter now reassembled, it’s time to reinstall it in the vehicle:

1. Position the starter back in its housing.
2. Use the wrench to tighten the bolts securely.
3. Reconnect the battery.

Step 7: Test the Starter

After installation, test the starter to ensure it is functioning correctly:

1. Turn the ignition key to start the engine.
2. Listen for any unusual sounds or issues during the starting process.
3. If the starter engages properly and the engine starts, the repair is successful.

Conclusion

You have successfully repaired the starter by replacing the Bendix, brushes, bushings, and bearings. Regular maintenance of starter components can prevent issues and prolong the life of your vehicle's starting system. If you encounter any further issues, consider consulting a professional mechanic for assistance.
