The whirring of a Craftsman lawn mower on a sunny afternoon is a quintessential sound of summer. But like any hardworking machine, your Craftsman lawn mower needs regular maintenance to keep running smoothly. One crucial aspect of that maintenance is checking and changing the engine oil. However, if you’re new to lawn mower upkeep, you might be wondering: Where is the oil plug on a Craftsman lawn mower? This article will guide you through the process of finding the oil plug, understanding its importance, and changing your Craftsman mower’s oil safely and efficiently.
The oil plug is typically located on the bottom of the engine crankcase, a metal housing that encloses the crankshaft and other moving parts. It’s a small, threaded plug that’s designed to be easily removed for draining the old oil. However, the exact location can vary slightly depending on the specific model of Craftsman lawn mower you have.
Identifying Your Craftsman Lawn Mower Model
Before you start searching for the oil plug, it’s essential to identify your specific Craftsman lawn mower model. This will help you find the correct location of the oil plug and other maintenance instructions. The model number is usually located on a sticker attached to the frame of the mower, typically near the engine.
Finding the Model Number
- Locate the sticker: The model number sticker is usually located on the frame of the mower, near the engine or on the side of the engine housing.
- Read the sticker carefully: The model number will be a series of letters and numbers.
- Record the model number: You can write down the model number or take a picture of it for later reference.
Once you have the model number, you can consult the Craftsman website or the user manual for your specific model to find detailed diagrams and instructions for locating the oil plug and changing the engine oil.
Locating the Oil Plug on Your Craftsman Lawn Mower
Now that you know your specific model, you’re ready to find the oil plug.
Common Locations
- Underneath the engine: The oil plug is typically located on the bottom of the engine crankcase, which is the metal housing that encloses the crankshaft and other moving parts.
- Near the engine’s drain hole: You may find it near the drain hole for the engine oil. The drain hole is usually a larger, circular opening that allows the old oil to flow out.
- Look for a threaded plug: The oil plug is usually a small, threaded plug that is easy to remove with a wrench or socket.
Tips for Finding the Oil Plug
- Clean the area: Before you start looking for the oil plug, clean any dirt or debris from the underside of the engine. This will make it easier to spot the plug.
- Use a flashlight: A flashlight can help illuminate the area under the engine and make it easier to see the oil plug.
- Consult the user manual: If you’re still having trouble finding the oil plug, refer to the user manual for your specific model. It should have diagrams and instructions that show you the location of the oil plug.
Understanding the Importance of the Oil Plug
The oil plug is a crucial part of your Craftsman lawn mower’s engine. It serves two primary functions:
- Draining old oil: The oil plug allows you to drain the old engine oil, which is essential for maintaining the engine’s performance and longevity. As oil ages, it loses its viscosity and lubricative properties, leading to increased friction and wear on engine components.
- Refilling with fresh oil: After draining the old oil, you can use the oil plug to refill the engine with fresh oil. The oil plug ensures that the engine has the correct amount of oil and that it remains in the crankcase.
Changing the Oil in Your Craftsman Lawn Mower
Once you’ve located the oil plug, you can proceed with changing the engine oil. This is a simple procedure that can be done by most homeowners.
Steps for Changing the Oil
- Prepare your materials: You’ll need a drain pan, a wrench or socket that fits the oil plug, fresh engine oil for your mower, and a funnel.
- Warm up the engine: Run the engine for a few minutes to warm up the oil, making it easier to drain.
- Locate the oil plug: Find the oil plug on the bottom of the engine crankcase.
- Loosen the oil plug: Use your wrench or socket to loosen the oil plug.
- Remove the oil plug: Once the oil plug is loosened, remove it completely and allow the oil to drain into the drain pan.
- Replace the oil plug: Once the oil has drained completely, replace the oil plug and tighten it securely.
- Add fresh oil: Use a funnel to pour the fresh engine oil into the engine’s oil fill hole. Refer to your user manual for the correct amount of oil for your model.
- Check the oil level: After adding the fresh oil, check the oil level using the dipstick on your mower.
Safety Precautions When Changing the Oil
Changing the oil in your Craftsman lawn mower is a relatively straightforward task, but it’s important to take some safety precautions to prevent accidents:
- Wear safety glasses: This will protect your eyes from oil splashes and debris.
- Work in a well-ventilated area: Engine oil can emit fumes that can be harmful if inhaled.
- Use a drain pan: This will prevent oil from spilling onto the ground and contaminating the environment.
- Dispose of the old oil properly: Engine oil is a hazardous material, so it’s important to dispose of it properly. Check with your local waste disposal authority for instructions on how to dispose of used engine oil.
- Do not overfill the engine: Overfilling the engine with oil can damage the engine.

FAQ
Where is the oil plug located on a Craftsman lawn mower?
The oil plug on a Craftsman lawn mower is typically located on the bottom of the engine, near the crankshaft. To find it, you will need to first identify the engine block, which is the large, cast-iron component that houses the engine’s moving parts. The oil plug is usually a small, round plug with a hexagonal or square head. It may be made of metal or plastic and will have a rubber gasket or washer to prevent leaks.
Once you have located the engine block, look for a small, round plug near the bottom. The plug may be painted the same color as the engine block, so it may be difficult to spot. If you are still having trouble finding the oil plug, consult your lawn mower’s owner’s manual for specific instructions.
What size is the oil plug wrench?
The size of the oil plug wrench will vary depending on the specific model of your Craftsman lawn mower. However, common sizes include 13/16 inch, 7/8 inch, and 1 inch. You can find a suitable wrench at your local hardware store or online. If you are unsure of the correct wrench size, consult your lawn mower’s owner’s manual or take the plug to your local hardware store for assistance.
What kind of oil should I use?
The type of oil you should use for your Craftsman lawn mower will depend on the engine’s specifications. Most Craftsman lawn mowers recommend using 10W-30 or 10W-40 SAE oil. These are multi-viscosity oils that provide good performance across a wide range of temperatures. Always check your owner’s manual for specific recommendations on oil type and viscosity.
How much oil should I add?
The amount of oil required for your Craftsman lawn mower will vary depending on the engine size. The maximum oil capacity is usually listed in your owner’s manual. When adding oil, it is important to avoid overfilling the engine. Overfilling can lead to excessive oil pressure and damage to the engine.
It’s best to check the dipstick before and after adding oil to ensure you are at the correct level. The dipstick is a metal rod with a handle located near the oil fill cap. When you pull the dipstick out, wipe it clean and then reinsert it. Pull it out again and the oil level should be somewhere between the “Add” and “Full” marks.
How often should I change the oil?
The frequency of oil changes will depend on how often you use your lawn mower and the conditions in which you use it. In general, it is recommended to change the oil every 25 to 50 hours of operation or at least once per year. You can also consult your owner’s manual for specific recommendations.
Changing the oil regularly helps to keep your lawn mower running smoothly and prevents premature engine wear. When changing the oil, make sure to use the correct type of oil and follow the manufacturer’s instructions.
Can I change the oil myself?
