Learning to change the oil on your Craftsman riding mower yourself can save you time and money each season. Knowing how to change oil on a craftsman riding lawn mower is a fundamental skill that extends the life of your machine and ensures it runs smoothly. This guide provides clear, step-by-step instructions to make the process straightforward, even if you’ve never done it before.
You will need a few basic tools and supplies. Gathering everything before you start makes the job quicker and prevents interruptions.
How To Change Oil On A Craftsman Riding Lawn Mower
This section covers the complete procedure from preparation to cleanup. Following these steps in order will help you complete the task safely and correctly.
Gather Your Tools And Materials
Having the right items on hand is crucial for a smooth oil change. You likely have many of these tools already in your garage.
- Fresh engine oil (Check your owner’s manual for the correct type and quantity, typically SAE 30 or 10W-30)
- A new oil filter (specific to your Craftsman model)
- An oil drain pan or old container
- Socket set or wrenches
- Oil filter wrench (strap-type often works best)
- Funnel
- Clean rags or paper towels
- Latex gloves (optional but recommended)
- A piece of cardboard or a tarp to kneel on
Prepare Your Riding Lawn Mower
Proper preparation ensures safety and makes the oil drain more completely. Never attempt to change oil immediately after using the mower.
Park On A Level Surface
Position your Craftsman mower on a flat, level area like your driveway or garage floor. This is essential for getting an accurate oil level reading later. Engage the parking brake securely.
Warm Up The Engine Slightly
Start the engine and let it run for 2-3 minutes. Warm oil flows out more easily, carrying more contaminants with it. Do not let the engine get hot, as this can be a burn hazard. Turn the engine off and remove the ignition key.
Disconnect The Spark Plug
For absolute safety, locate the spark plug wire and disconnect it. This prevents any accidental engine starts while you are working underneath or around the mower.
Drain The Old Engine Oil
This is the messiest part, so take your time. Place your cardboard or tarp underneath the drain area to catch any drips.
- Locate the oil drain plug on the underside of the mower deck, near the engine. Consult your manual if you have trouble finding it.
- Place your oil drain pan directly beneath the drain plug.
- Using the correct size socket or wrench, carefully loosen the drain plug. Once loose, unscrew it by hand but be prepared for oil to flow immediately.
- Let the oil drain completely into the pan. This may take several minutes. Tip: gently rocking the mower side-to-side (while it’s securely braked) can help dislodge any trapped oil.
- Once drained, wipe the area clean and reinstall the drain plug. Tighten it snugly with the wrench, but avoid overtightening which can strip the threads.
Replace The Oil Filter
Changing the filter is as important as changing the oil. A new filter removes microscopic particles that can wear down engine components.
- Locate the oil filter on the side of the engine. It is usually a cylindrical metal canister.
- Position your drain pan under the filter to catch residual oil that will spill out.
- Use your oil filter wrench to turn the old filter counterclockwise to loosen it. You may need to puncture it with a screwdriver for leverage if it’s stuck, but this is messy.
- Once loose, unscrew it completely by hand. Let the oil drain into your pan.
- Take a clean rag and wipe the filter mounting surface on the engine. Ensure the old filter’s gasket is not stuck to the engine.
- Take your new filter and dip your finger in some fresh oil. Lightly coat the rubber gasket on the top of the new filter. This ensures a good seal and makes future removal easier.
- Screw the new filter onto the engine by hand. Once the gasket makes contact, tighten it an additional three-quarter turn by hand. Do not use the filter wrench for this final tightening.
Add The New Engine Oil
Now you are ready to refill the engine with fresh, clean oil. Using the type recommended by Craftsman is vital for engine performance.
- Locate the oil fill tube on the top of the engine. It usually has a dipstick attached to the cap.
- Insert a clean funnel into the fill tube.
- Slowly pour in the recommended amount of new oil. It is often best to start with about 80% of the stated capacity, then check the level.
- Replace the oil fill cap and dipstick.
- Start the engine and let it run for about 30 seconds. This circulates the new oil and fills the new filter. Check around the drain plug and filter for any leaks.
- Turn off the engine and wait a minute for the oil to settle back into the crankcase.
- Pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again to check the level. The oil should be between the “Full” and “Add” marks. Add small amounts of oil as needed to reach the proper level.
Dispose Of The Old Oil And Filter Properly
Never pour used oil on the ground or into drains. It is harmful to the enviroment and illegal in most places. Used motor oil and filters are highly recyclable.
- Pour the used oil from your drain pan into a clean, sealable container like the original oil bottle. Label it clearly.
- Place the old oil filter in a plastic bag to prevent drips.
- Take both the used oil and the old filter to a recycling center. Most auto parts stores and service stations accept them for free.
Troubleshooting Common Oil Change Issues
Sometimes, you might encounter a small problem. Here are solutions to a few common issues.
Stripped Oil Drain Plug
If the drain plug threads are damaged, do not force it. You may need to replace the plug or, in worse cases, the oil pan. A mechanic can often install a threaded insert to repair it.
Overfilled With Oil
If you accidentally put too much oil in the engine, you must remove the excess. You can use a hand pump or a simple turkey baster dedicated to this purpose to suction oil out through the fill tube until the dipstick reads correctly.
Oil Leaks After Change
If you notice a leak, first identify the source. Common spots are the drain plug or the oil filter. Ensure the drain plug is tight and the filter gasket is properly seated. A leak from the filter usually means it needs to be tightened slightly or was cross-threaded.
Frequently Asked Questions
Here are answers to some common questions about maintaining a Craftsman riding mower.
What Type Of Oil Does A Craftsman Riding Mower Use?
Most Craftsman riding mower engines use SAE 30 weight oil for standard temperatures. For variable climates, a 10W-30 is often recommended. Always check your specific model’s owner manual for the manufacturer’s exact specification, as using the wrong oil can cause engine damage.
How Often Should I Change The Oil In My Craftsman Mower?
A good rule is to change the oil every 50 hours of operation or at least once per mowing season, whichever comes first. If you use your mower extensively, you may need to change it more frequently. Very dusty conditions also warrant more frequent changes.
Can I Use Synthetic Oil In My Lawn Mower?
Yes, you can use synthetic oil if it meets the engine manufacturer’s specifications. Synthetic oils can offer better performance in extreme temperatures and provide longer engine life. However, they are more expensive than conventional oils, so weigh the cost against your mower’s usage.
Where Is The Oil Drain Plug On A Craftsman Riding Mower?
The oil drain plug is typically located on the underside of the mower deck, near the bottom of the engine crankcase. Some newer models have a dedicated drain tube that makes the process cleaner. If you cannot find it, refer to your owner’s manual for a diagram of your specific model.
Do I Need To Change The Oil Filter Every Time?
Yes, it is highly recommended to change the oil filter every time you change the oil. The filter traps harmful debris, and a clogged or old filter can restrict oil flow, leading to premature engine wear. The small extra cost of a filter is worth the engine protection it provides.
