how to tell if cam chain tensioner is bad harley
Are you a proud owner of a Harley-Davidson motorcycle? If so, you know that proper maintenance is key to keeping your ride in top condition.
One of the most critical components of your bike’s engine is the cam chain tensioner, which helps ensure that the timing of the camshaft is just right.
Unfortunately, over time, this crucial part can start to wear down and cause serious problems.
In this blog post, we’ll explore how to tell if your cam chain tensioner is bad and what you can do to fix it.
How to tell if cam chain tensioner is bad harley?
A cam chain tensioner is an important component of Harley’s engine that ensures the cam chain stays tight and doesn’t slip or skip.

Over time, the tensioner can wear out or become faulty. It can cause issues with your bike’s performance.
Here are some signs that your Harley’s cam chain tensioner might be bad:
1. Unusual engine noises:
One of the most common signs of a bad cam chain tensioner is a rattling or knocking noise coming from the engine.
This can happen because the tensioner is not able to keep the cam chain tight, causing it to slap against other parts of the engine.
2. Poor performance:
A bad cam chain tensioner can also cause your Harley to run poorly. You may notice a lack of power or acceleration, or the engine may feel rough or sluggish.
3. Check engine light:
If the cam chain tensioner is not working properly, it can cause the check engine light to come on.
This is because the tensioner is responsible for maintaining proper timing and if it is not working properly, it can throw off the engine’s timing.
4. Oil leaks:
The cam chain tensioner is typically located near the engine’s oil system.
If the tensioner is bad, it can cause oil to leak from the engine, which can be a messy and potentially hazardous issue.
5. Visible wear:
Finally, you can also physically inspect the cam chain tensioner to see if it is worn out or damaged.
Look for signs of cracking or breakage, as well as any visible wear on the tensioner or the cam chain itself.
What are the causes of a Bad Cam Chain Tensioner?

A bad cam chain tensioner can cause a variety of problems in your engine, including poor performance, increased wear and tear on engine components, and even engine failure.
Here are some of the common causes of a bad cam chain tensioner:
1. Wear and Tear:
One of the most common causes of a bad cam chain tensioner is simply wear and tear.
Over time, the tensioner can become worn or damaged, causing it to malfunction and fail to keep the cam chain properly tensioned.
2. Lack of Maintenance:
Regular maintenance is essential to keep your engine running smoothly, and this includes checking and replacing the cam chain tensioner when necessary.
If the tensioner is not replaced as needed, it can become damaged and fail.
3. Dirty or Contaminated Oil:
Another cause of a bad cam chain tensioner is dirty or contaminated oil.
If the oil is not changed regularly, it can become dirty and contaminated with debris, which can cause the tensioner to become stuck or damaged.
4. Incorrect Installation:
If the cam chain tensioner is not installed correctly, it can cause problems with the engine’s timing and performance.
It’s important to follow the manufacturer’s instructions carefully and ensure that the tensioner is installed correctly.
5. Defective Parts:
In some cases, the cam chain tensioner may be defective or made with faulty parts.
This can cause the tensioner to fail prematurely or not function properly, leading to engine problems.
How to prevent a Cam Chain Tensioner from future damage?

Here are some tips to prevent your cam chain tensioner from going bad:
1. Regular Maintenance:
It is crucial to get your car serviced regularly to ensure that all the components, including the cam chain tensioner, are functioning correctly.
Regular oil changes and replacing worn-out parts will help prevent problems in the long run.
2. Keep the Engine Clean:
Dirt and debris can accumulate in the engine and cause problems with the cam chain tensioner.
Keep the engine clean by regularly wiping down the engine and removing any debris.
3. Use High-Quality Oil:
Using high-quality oil is essential to keep the engine running smoothly and reduce wear and tear on the cam chain tensioner.
Be sure to use the recommended oil viscosity for your vehicle, and change the oil as per the manufacturer’s recommendations.
4. Avoid Overloading the Engine:
Overloading the engine can cause unnecessary stress on the cam chain tensioner, leading to potential problems.
Avoid overloading the engine by ensuring that you don’t exceed the maximum weight limit or tow more than the recommended amount.
5. Listen for Strange Noises:
If you hear any strange noises coming from the engine, it’s essential to get it checked out by a mechanic immediately.
Strange noises can be an indication that something is wrong with the cam chain tensioner or other engine components.
6. Avoid Abrupt Changes in RPM:
Abrupt changes in RPM can cause stress on the cam chain tensioner, leading to potential damage.
Avoid harsh acceleration or deceleration and drive smoothly to prevent unnecessary stress on the engine.
How to maintain a Cam Chain Tensioner?

Here are some tips on how to maintain your cam chain tensioner:
1. Regular Inspection:
You should regularly inspect the cam chain tensioner to make sure that it is functioning properly.
Check for any signs of wear or damage, and replace the tensioner if necessary.
2. Lubrication:
Your cam chain tensioner should be properly lubricated in order to work effectively. Make sure that there is sufficient oil flow to the tensioner and that the oil is clean.
3. Tension Adjustment:
If you notice that the cam chain is loose, it may be necessary to adjust the tension on the tensioner. Follow the manufacturer’s instructions for making this adjustment.
4. Replacement:
Over time, the cam chain tensioner may become worn or damaged and will need to be replaced. Make sure that you use the correct replacement part for your engine.

FAQs
1. What Is A Cam Chain Tensioner, And What Does It Do?
A cam chain tensioner is a component in your Harley’s engine that helps maintain the proper tension on the timing chain, which controls the opening and closing of the engine’s valves.
The tensioner ensures that the timing chain stays in place and doesn’t jump off the sprockets, which can cause major engine damage.
2. Can A Bad Cam Chain Tensioner Cause Engine Damage?
Yes, a bad cam chain tensioner can potentially cause serious engine damage if it’s not addressed quickly.
If the timing chain jumps off the sprockets or skips a tooth, the engine’s valves can collide with the pistons, causing major internal damage.
3. How Often Should I Have My Cam Chain Tensioner Inspected/Replaced?
The frequency with which you should have your cam chain tensioner inspected/replaced can vary depending on factors like your riding style, mileage, and the age of your bike.
However, most Harley mechanics recommend having the tensioner inspected every 25,000 miles and replaced every 50,000-75,000 miles as a preventative measure.
If you notice any of the signs of a bad cam chain tensioner mentioned above, you should have it checked out right away regardless of your mileage.
