Preparing The Lawn Mower
Before replacing the drive belt on your Craftsman lawn mower, it’s crucial to prepare the mower properly. This ensures your safety and makes the task easier. Follow these steps to get your mower ready.
Disconnecting The Spark Plug
First, disconnect the spark plug. This prevents accidental starts while working on the mower. Locate the spark plug at the front of the engine. Pull off the rubber boot attached to the spark plug.
Use a spark plug wrench to remove the spark plug. Keep it aside in a safe place. This step is vital to ensure your safety.
Elevating The Mower
Next, elevate the mower for better access to the drive belt. Use a sturdy jack or a lift. Place it under the mower’s frame. Carefully lift the mower until you have enough clearance.
Alternatively, you can use a pair of ramps. Drive the mower onto the ramps to elevate it. Ensure the mower is stable before proceeding.
Always work on a flat surface. This prevents the mower from tipping over.

Removing The Old Drive Belt
Removing the old drive belt from your Craftsman lawn mower is a simple task. It requires a bit of patience and some basic tools. Follow these steps to ensure a smooth process. Let’s start by locating the drive belt.
Locating The Drive Belt
The drive belt is usually found under the mower deck. First, ensure the mower is off and the spark plug is disconnected. This prevents any accidental starts. Next, tilt the mower to its side carefully. You will see the drive belt running around the pulleys.
Steps To Remove The Belt
Now that you’ve located the drive belt, it’s time to remove it. First, use a wrench to loosen the bolts holding the belt guard. Remove the guard and set it aside. Next, slide the belt off the pulleys. It might be tight, so be gentle but firm. Finally, pull the belt out from the mower completely. Now, you’re ready to install the new drive belt.
Installing The New Drive Belt
Replacing the drive belt on your Craftsman lawn mower can seem daunting. But with the right steps, it is manageable. This guide will help you through installing the new drive belt. Follow these simple instructions to keep your lawn mower running smoothly.
Positioning The New Belt
First, you need to position the new belt correctly. Start by placing the belt around the engine pulley. This is located near the engine. Then, guide the belt around the mower deck pulleys. Ensure the belt sits properly in the grooves of each pulley. Double-check the belt path with the diagram in your mower’s manual. This step is crucial for the belt to function correctly.
Here is a simple way to position the new belt:
- Place the belt around the engine pulley.
- Guide it around the deck pulleys.
- Ensure it sits in the grooves of each pulley.
- Check the belt path with the manual’s diagram.
Ensuring Proper Tension
Proper tension is key to the belt’s performance. A loose belt can slip off or wear out quickly. A belt that is too tight can cause damage. To check the tension, press down on the belt midway between two pulleys. The belt should move about half an inch. If it moves more, it is too loose. If it moves less, it is too tight.
Adjust the tension using the tensioner pulley:
- Loosen the tensioner pulley bolt.
- Adjust the pulley to increase or decrease tension.
- Tighten the bolt to secure the pulley in place.
Once adjusted, test the belt tension again. Repeat the steps if necessary. Proper tension ensures the belt will last longer and your mower will run smoothly.
Testing The Installation
After replacing the drive belt on your Craftsman lawn mower, it’s essential to test the installation. This ensures everything works correctly and safely. Follow the steps below to test your new drive belt installation.
Reconnecting The Spark Plug
Before testing the lawn mower, reconnect the spark plug. This step is crucial to ensure the engine will start.
- Locate the spark plug wire.
- Firmly push the wire onto the spark plug.
- Ensure a secure connection.
Once the spark plug is reconnected, you can proceed to run a test.
Running A Test
Now it’s time to run a test to check the new drive belt. Follow these steps:
- Move the mower to a clear, open area.
- Start the engine by pulling the starter cord.
- Engage the drive system by pushing the drive control lever.
Observe the mower’s movement. The mower should move smoothly without any jerking or slipping. If it does, your installation is successful.
If you notice any issues, double-check the belt installation. Ensure it’s properly aligned and securely in place.
Maintenance Tips
Keeping your Craftsman lawn mower in top condition ensures it runs efficiently. Regular maintenance is key to extending the life of your mower. Here are some essential maintenance tips to help you keep your mower’s drive belt in good shape.
