Step-by-Step Guide to Rebuilding Your 19 HP Kawasaki Engine Starter

Step 1: Safety First

Before you start any work on your Kawasaki engine, ensure your workspace is safe. Disconnect the battery to prevent any accidental electrical shocks. Also, wear safety gloves and eye protection to avoid injury from small parts or debris.

Step 2: Remove the Starter

Locate the starter on your 19 HP Kawasaki engine. It’s usually positioned near the flywheel and attached to the engine block. Here’s how to remove it:

1. Disconnect the battery: Always start by disconnecting the negative terminal of the battery to ensure there’s no power flowing to the starter.
2. Locate the starter bolts: Use your socket wrench to remove the bolts that hold the starter in place.
3. Disconnect the wiring: Carefully remove the wires attached to the starter using a screwdriver or pliers, noting where each wire is connected for reassembly later.

Once you’ve removed the starter, place it on a clean workbench.

Step 3: Disassemble the Starter

With the starter out of the engine, it’s time to take it apart. The goal is to open the starter casing to access the internal components that will be replaced using the 21153-7010 16121 Starter Rebuild Kit.

1. Remove the screws or bolts: Use your socket wrench or screwdriver to remove any screws or bolts that hold the starter casing together.
2. Carefully separate the casing: Gently pry open the starter casing, being cautious not to damage any components. Lay the casing and all parts neatly on your workbench in the order you remove them. This will help you remember how to reassemble them later.

Step 4: Inspect the Components

Once the starter is disassembled, inspect all the internal parts. You’re looking for wear, corrosion, or damage. The most common parts that need replacing are the brushes, bushings, and armature—all of which are typically included in the 21153-7010 16121 Starter Rebuild Kit.

• Brushes: These wear out over time due to friction and should be replaced if they’re worn down.
• Bushings: Check the bushings for wear, as this can cause misalignment in the starter shaft.
• Armature: If the armature looks scorched or damaged, you’ll want to replace it with the new one provided in the kit.

Step 5: Clean the Parts

Before reassembling your starter, take the time to clean all the reusable parts. Use an electric motor cleaner or a similar product to remove any dirt, debris, or corrosion. Wipe everything down with a clean rag to ensure it’s free of contaminants.

Step 6: Rebuild the Starter with the 21153-7010 16121 Kit

Now it’s time to rebuild the starter using the components from your 21153-7010 16121 Starter Rebuild Kit. Follow these steps:

1. Replace the brushes: Install the new brushes into the brush holder. Make sure they fit snugly and are aligned properly.
2. Install new bushings: If your old bushings are worn, use the new ones from the kit. Insert them into their respective locations in the starter casing.
3. Replace the armature: If the armature in your starter was damaged, install the new one. Ensure that the new armature is aligned properly with the brushes and bushings.
4. Reassemble the starter casing: Carefully fit the starter casing back together, ensuring that all components are aligned and nothing is pinched or misaligned.

Step 7: Reinstall the Starter

With your starter rebuilt, it’s time to reinstall it in your 19 HP Kawasaki engine. Follow the reverse order of the removal process:

1. Reconnect the wiring: Attach the wires to their respective terminals, making sure each connection is tight.
2. Bolt the starter back in place: Use your socket wrench to secure the starter with the bolts you removed earlier.
3. Reconnect the battery: Finally, reconnect the negative terminal of the battery to restore power to the engine.

Step 8: Test the Starter

With everything reinstalled, it’s time for the moment of truth—testing your newly rebuilt starter. Turn on your engine and listen for smooth cranking. If everything was done correctly, the engine should start easily and run smoothly.

If you experience any issues, double-check all the connections and ensure that all components were installed correctly.
