Well, one vital component that plays a crucial role in the engine’s smooth functioning is the crankshaft. The crankshaft is responsible for converting the up-and-down motion of the pistons into rotary motion, which ultimately turns the wheels of your car. However, just like any other mechanical part, the crankshaft can sometimes become bent.
A bent crankshaft can lead to numerous problems and can significantly impact the performance and longevity of your vehicle. In this article, we will explore some common signs that indicate you may have a bent crankshaft. So, let’s dive in and learn more!
How to Check if Your Lawn Mower Crankshaft is Bent
If you suspect that your lawn mower’s crankshaft may be bent, there are a few telltale signs you can look out for. First, check for any strange vibrations or wobbling while the mower is running. A bent crankshaft can cause the blade to spin unevenly, resulting in these types of movements.
Next, pay attention to the sound your mower makes. A bent crankshaft can create an abnormal knocking or thumping noise, which is a clear indication that something is not right. Lastly, inspect the cutting pattern of your grass.
A bent crankshaft can cause the blade to mow the grass unevenly, leaving patches of uncut or shorter grass. If you notice any of these signs, it’s best to have a professional mechanic take a closer look to confirm if your lawn mower’s crankshaft is indeed bent.
Step 1: Remove the Spark Plug
If you suspect that your lawn mower’s crankshaft is bent, it is important to confirm your suspicions before attempting any repairs. One way to do this is by checking the alignment of the crankshaft. To begin, you’ll need to remove the spark plug.
This may require using a spark plug wrench or socket to loosen and remove the spark plug from the engine. Once the spark plug is removed, carefully inspect the electrode and insulator for any signs of damage or wear. By removing the spark plug, you will be able to rotate the engine manually and check the alignment of the crankshaft.
If you notice any wobbling or misalignment, it is likely that the crankshaft is bent and will need to be replaced. However, it is important to note that a bent crankshaft can also be caused by other factors, such as improper maintenance or excessive wear. Therefore, it is always best to consult a professional if you are unsure about the condition of your lawn mower’s crankshaft.
Step 2: Examine the Blade

The flywheel is an essential part of the lawn mower’s engine, responsible for storing energy and providing rotational momentum to keep the engine running smoothly. If the crankshaft is bent, it can cause the flywheel to wobble or become misaligned, leading to performance issues and potential damage to other engine components.
To inspect the flywheel, start by removing the engine shroud or protective cover to gain access to the flywheel. Take a close look at the flywheel for any signs of damage, such as dents, cracks, or warping. Check if the flywheel spins smoothly without any wobbling or uneven movement.
If you notice any abnormalities or suspect that the crankshaft may be bent, it’s best to consult a professional for further inspection and repair. Taking the time to properly inspect the flywheel can help identify any issues with the crankshaft and ensure that your lawn mower operates efficiently and effectively.
Step 4: Check for Visible Damage

A bent crankshaft can cause your mower to vibrate excessively and even damage other components of your machine. So, how do you check if your lawn mower’s crankshaft is bent? First, you’ll want to visually inspect the crankshaft for any visible damage.
Look for signs of bending, such as a kink or twist in the metal. Additionally, check for any cracks or breaks in the surface of the crankshaft. These are all indications that your crankshaft may be bent and in need of repair or replacement.
Remember, a bent crankshaft can hinder the performance of your lawn mower, so it’s essential to address the issue as soon as possible.
What to Do if Your Crankshaft is Bent
If you suspect that your lawn mower’s crankshaft may be bent, there are a few signs you can look out for. One common indication is excessive vibration during operation. If your mower shakes or rattles more than usual, it could be a result of a bent crankshaft.
Another symptom to watch for is difficulty starting the engine. A bent crankshaft can cause the piston to bind, making it harder for the engine to turn over. Additionally, you may notice uneven cutting patterns or a decrease in overall cutting performance.
If your lawn mower is leaving patches of uncut grass or struggling to power through thicker vegetation, a bent crankshaft could be to blame. If you suspect that your mower’s crankshaft is bent, it’s best to consult with a professional. They will be able to accurately diagnose the issue and recommend the best course of action, whether it’s repairing the crankshaft or replacing it altogether.
Option 1: Repair the Crankshaft

A bent crankshaft can cause a variety of problems, including vibration, poor performance, and even engine failure. So, what can you do if you find yourself in this situation? One option is to have the crankshaft repaired.
Repairing a bent crankshaft is not a simple task and should only be done by a skilled professional. The first step in the repair process is to remove the crankshaft from the engine. This can be a time-consuming and labor-intensive process, as the crankshaft is often buried deep within the engine.
Once the crankshaft is removed, it can be straightened using specialized tools and techniques. During the straightening process, heat is often applied to the crankshaft to make it more malleable. The crankshaft is then carefully manipulated back into its proper shape.
After the straightening process is complete, the crankshaft is thoroughly inspected for any additional damage. If any other issues are found, they will need to be addressed before the crankshaft can be deemed safe for use. Once the repairs are completed and the crankshaft is deemed suitable for use, it can be reinstalled in the engine.
This is another complex process that requires attention to detail and precision. It’s important to ensure that all components are properly aligned and tightened to prevent any further issues. It’s worth noting that while repairing a bent crankshaft is possible, it may not always be the best option.
Depending on the extent of the damage and the age of the engine, it may be more cost-effective to replace the crankshaft instead of attempting repairs. A professional mechanic will be able to assess the situation and provide guidance on the best course of action. In conclusion, if you find that your crankshaft is bent, it’s important to take immediate action.
Option 2: Replace the Crankshaft

In conclusion, determining if your lawn mower crankshaft is bent can be a bit like solving a Sherlock Holmes mystery. You have to use your powers of deduction and observation to gather the clues that will lead you to the truth. Look for signs like excessive shaking, abnormal noises, or a blade that spins unevenly like a prima donna ballerina on a drunken night out.
And remember, just like a savvy detective, it’s important to trust your instincts. If something feels off, don’t brush it aside like Sherlock brushes off personal hygiene. Instead, take immediate action and inspect that crankshaft with the precision of a magnifying glass-wielding detective.
