Harley-Davidson, a brand that has long been synonymous with American motorcycling, made headlines in recent years due to a widespread issue with its camshaft tensioners.
The recall affected tens of thousands of motorcycles, sparking concerns among riders worldwide.
In this blog post, we’ll explore what caused the recall, the potential risks, and what Harley-Davidson owners need to know to stay safe on the road.
Harley Davidson Cam Tensioner Recall
Harley Davidson has issued several recalls related to cam chain tensioners, including a recent one in October 2022 affecting approximately 200,000 trikes and touring motorcycles.
The recall is due to potential issues with the cam chain tensioner shoe, which could lead to engine damage and increased crash risk. Harley Davidson has stated that they will perform all necessary repairs free of charge.
What is the Cam Tensioner Issue with Harley Davidson?
Some Harley Davidson owners have reported issues with premature cam chain tensioner failure.
While some have not faced any problems, the issue has become a concern for some riders.
The cam tensioner issue has been blown out of proportion and has become a hysteria, fueled in no small way by people who have been making a living installing cam gear drives for the past six or seven years.
Harley Cam Chain Tensioner Problem Years
The Harley cam chain tensioner problem is a well-known issue that has affected certain years of Harley Davidson motorcycles.
The problem began with the introduction of the Twin Cam engine in 1999.
The cam chain problem persisted until 2007. The cam chain tensioner issue has been blown out of proportion by some, but it has affected many Harley owners.
What Year Did Harley Change To Hydraulic Cam Chain Tensioners?
When Harley-Davidson released the new Twin Cam 96, it had hydraulic tensioners fed by oil and Delrin-style pads.
This upgrade placed less tension when at lower RPMs, and a lighter preload was placed on the chain, resulting in fewer failures.
However, some Harley owners are still reporting issues with the cam chain tensioner on newer models.
The plastic spring-loaded cam chain follower in the affected years fails, causing metal shavings and oil flow issues.
This can lead to skipped gears, engine misfires, power loss, and even engine failure.
While many Harley owners have not experienced the problem, it is difficult to predict when the tensioner will fail, as some have reported failures at as little as 15,000 miles or less.
The longevity problem of the cam system of the Harley Twin Cam still exists, and many users have experienced untimely and horrible engine failure.
To prevent the Harley cam chain tensioner failure, it is recommended to inspect the tensioner regularly and replace it with an upgraded version if necessary.

Alternative to Harley Davidson’s cam tensioner – Twin Cam Tensioner Pads:
If you’re looking for an alternative to Harley Davidson’s cam tensioner, you can try Twin Cam Tensioner Pads.
These pads were tested on a 2001 Dyna with 13,000 miles on the original OEM cam chain tensioners.
The bike ran another 13,000 miles on the tensioner pads to duplicate the miles and conditions.
The test bike was run with the Harley maintenance schedule of oil changes at every 5,000 miles. The results were positive, and the pads performed well.
Twin Cam Tensioner Inspection
Here are some important things to know about the inspection process:
Regular inspection is critical:
The cam chain tensioner keeps proper tension in the cam or timing chain, which connects the engine crankshaft to a camshaft.
Without proper tension, the engine can suffer damage. Regular inspection is essential to ensure that the tensioner is working correctly.
There are different methods of inspecting the cam chain tensioner on Twin Cam engines.
Some inspection procedures require removing the valve covers and rocker supports, while others involve removing the oil pump and cam.
Regardless of the method used, it is important to inspect both the outer and inner shoes of the tensioner, as both can wear out and cause damage to the engine.
When to replace:
Inspecting the tensioner alone is not always sufficient. If the tensioner shows any noticeable wear, it is best to replace it rather than just inspecting it.
Many mechanics recommend replacing the cam chain tensioner every 20,000 to 30,000 miles, depending on the model.
There are upgrade kits available that can improve the performance and durability of the cam chain tensioner.
Some of these kits include the Screamin’ Eagle Hydraulic Cam Chain Tensioner Plate Upgrade Kit, which updates the tensioner to the latest design featured on Twin Cam 96 engines.
Inspecting or replacing the cam chain tensioner can be expensive, with some dealerships charging up to $400 just to inspect the shoes.
However, there are affordable aftermarket options available, such as the Cam Chain Tensioner Guide for Harley Twin Cam engines, which can be purchased on eBay.
