how to change spark plug on craftsman lawn tractor

Craftsman lawn tractors are one of the most reliable lawn tractors on the market. However, like all machines, lawn tractors also require regular maintenance. The spark plug is one of the essential components of the lawn tractor's engine. The spark plug produces a spark that ignites the gasoline, which powers the engine. Changing the spark plug is crucial to ensure the smooth functioning of the engine. This article provides a step-by-step guide on how to change the spark plug on a Craftsman lawn tractor.

Step-by-Step Guide

Follow the steps below to change the spark plug on a Craftsman lawn tractor:

Step 1: Preparation

The first step is to prepare for the spark plug change. Gather the necessary tools, including a spark plug wrench/socket, ratchet, spark plug feeler gauge, and a new spark plug. Additionally, you should wear protective gear, including gloves and goggles, to shield yourself from the spark plug's electrode.

Step 2: Locate the spark plug

The Craftsman lawn tractor's spark plug is located on the engine block. To locate the spark plug, look for a black, rubber-coated wire that leads to a small, metal cylinder. This cylinder is the spark plug.

Step 3: Disconnect the wire

Before removing the spark plug, first, disconnect the black, rubber-coated wire. To do this, gently pull the wire from the spark plug's top.

Step 4: Remove the old spark plug

Insert the spark plug wrench/socket onto the spark plug and turn it counterclockwise. Keep turning the wrench until the spark plug is loose enough to turn by hand. Continue to turn the spark plug counterclockwise, and carefully remove it from the engine block using your hand.

Step 5: Check and adjust the gap on the new spark plug

Check the gap on the new spark plug using a spark plug feeler gauge. The gap should match the old spark plug specifications and should be adjusted if necessary.

Step 6: Install the new spark plug

Once the gap has been adjusted on the new spark plug, install it in the engine block by hand. Be sure to thread the spark plug carefully so as not to damage the threads. Once the spark plug is in place, tighten it using the spark plug wrench/socket. Make sure it's snug but not too tight.

Step 7: Reconnect the wire

Reconnect the black, rubber-coated wire to the spark plug by pushing it onto the spark plug's top.

Step 8: Test the new spark plug

Start the Craftsman lawn tractor to test the new spark plug. If the engine runs smoothly, you have successfully changed the spark plug.

Conclusion

In conclusion, changing the spark plug on a Craftsman lawn tractor is a simple task that any lawn tractor owner can do. By following the guide above, you can replace the spark plug quickly and without any hassle. Remember to check and change the spark plug regularly to ensure the smooth functioning of the lawn tractor engine.
