1969 CB350 K1: Starter Removal - Save on Repair Costs

The Honda CB350 K1, a classic beauty from 1969, demands respect and proper care. While known for its reliability, even these legendary machines can experience issues, particularly with the starter motor. A malfunctioning starter can leave you stranded, and professional repair can be expensive. This guide will walk you through the process of removing your CB350 K1's starter motor, empowering you to diagnose problems, potentially saving you considerable repair costs.

Why Remove the Starter?

Before diving into the removal process, let's understand why removing the starter is often necessary. Common issues requiring starter removal include:

• Starter Motor Failure: A common problem in older bikes, failure can manifest as a grinding noise, a complete lack of engagement, or intermittent operation. Removing the starter allows for a thorough inspection and repair.
• Bendix Drive Problems: The bendix drive is the mechanism that engages the flywheel. Problems here often result in a grinding noise without the engine starting. Removal gives access to diagnose and replace the bendix if needed.
• Wiring Issues: Faulty wiring within the starter circuit can prevent it from functioning. Removing the starter enables you to inspect and troubleshoot the wiring.
• Preventative Maintenance: Regular inspection and cleaning of the starter motor can prevent future issues and extend its lifespan.

Tools You'll Need

Before you begin, gather the necessary tools to make the process smooth and efficient:

• Socket Set: You'll need various sizes, including those appropriate for the starter motor bolts.
• Wrench Set: May be necessary for certain nuts and bolts.
• Screwdrivers: Phillips and flathead, for various fasteners.
• Gloves: To protect your hands.
• Shop Rags or Clean Cloths: For cleaning and wiping.
• Service Manual: A Honda CB350 K1 service manual is invaluable for detailed diagrams and specifications. This is highly recommended.

Step-by-Step Starter Removal

This process assumes a basic level of mechanical aptitude. If you're uncomfortable working on your motorcycle, consult a qualified mechanic. Always disconnect the negative battery terminal before starting any work on your electrical system.

1. Drain the Engine Oil (Optional but Recommended): This provides easier access to certain components.
2. Remove the Airbox and Carburetors (If Necessary): Access to the starter might require removing some components depending on your method. Refer to your service manual for the correct procedure.
3. Locate the Starter Motor: The starter is typically located on the lower left side of the engine (as you sit on the bike).
4. Disconnect Electrical Connections: Carefully disconnect the electrical connectors leading to the starter motor. Take photos or make notes to remember their placement for reassembly.
5. Remove Mounting Bolts: Use the appropriate sockets and wrenches to remove the bolts securing the starter motor to the engine case. The number of bolts will vary.
6. Remove the Starter Motor: Once the bolts are removed, carefully remove the starter motor from its mounting position. It may be a tight fit.

Troubleshooting and Repair

Once the starter is removed, you can inspect it for damage:

• Visual Inspection: Check for any obvious physical damage, such as broken wires, loose connections, or corrosion.
• Testing the Solenoid: The solenoid is responsible for engaging the starter motor. Testing it involves using a multimeter to check for continuity. Consult your service manual or online resources for specific testing procedures.
• Bendix Drive Inspection: Carefully examine the bendix drive for wear, damage, or binding. A faulty bendix is a common cause of starting problems.

What if the Starter is beyond repair?

If the starter motor or bendix drive is beyond repair, replacement is necessary. You can find replacement parts online or through motorcycle parts suppliers. Always choose high-quality parts from reputable suppliers to ensure reliable performance.

Reinstallation

Once repairs or replacements are complete, reinstall the starter motor in the reverse order of removal. Ensure all connections are secure and that all bolts are tightened to the correct torque specifications (refer to your service manual). Reconnect the battery and test the starter.

Frequently Asked Questions
