Riding a Harley-Davidson is a thrilling experience, but to make sure it runs smoothly and safely, it is important to stay up to date on maintenance. One of the most important tasks in keeping your Harley in top shape is changing the drive belt. How often do you change the drive belt on a Harley-Davidson? Read on to find out the answer and the steps to take to keep your Harley in excellent condition.
What is a Drive Belt, and What is its Role?
Harley-Davidson bikes have long been a symbol of premium American engineering and craftsmanship, thanks to the powerful engines, distinctive style, top-notch features, and other features that deliver comfortable rides. The engineering makes use of various components to deliver an extremely powerful performance. One of the components that help deliver premium performance and help drive the engine is the drive belt.
A drive belt or also referred to as a fan belt or a serpentine belt is a rubber or polymer belt responsible for connecting the engine’s crankshaft to the transmission. This will then transmit power to the bike’s rear wheel. The drive belt is responsible for transferring power from the engine of the bike to the wheels, while its smooth operation will be crucial for the bike’s performance. The drive belt is typically made using high-strength materials like carbon fiber or Kevlar.
This way, the drive belt can withstand the tension and stress placed on it. Drive belts are designed to be extremely durable and flexible, which allows them to endure the rigors of constant use while remaining reliable over time.
The drive belt’s smooth operation will be important to ensure the bike’s optimal performance, especially when you’re riding at high speeds. One of the significant advantages of a drive belt over a traditional chain drive is that it’ll require less maintenance. Chain drives need regular lubrication and adjustments, which can often be messy and time-consuming. On the other hand, drive belts tend to be self-lubricating and need little maintenance, which makes them ideal for Harley-Davidson bikes.
Like other components of a bike, the drive belt will eventually wear out and require replacing. You will need to be on the lookout for signs that your drive belt needs replacing. If your drive belt breaks during the ride, it could result in significant damage to the bike’s engine and transmission.
How Often Should You Change the Drive Belt on Your Harley-Davidson Bike
Most bikers know how important it is to have a well-maintained ride. However, not only beginners, but even veterans can make the mistake of forgetting to look after their Harley’s drive belt. The drive belt is essentially a strong, stretch-resistant belt made from tensile cords. As drive belts can easily last as much as 100,000 miles before having to be replaced, you might lose track of this key aspect of motorcycle maintenance.
When the drive belt is first installed, you should inspect it after the first 1,000 miles. Whether you take your bike to a professional mechanic or examine it yourself, a tension check must also be completed. Then, it’ll be a smart idea to develop a habit of checking out your Harley’s drive belt each time you change the oil (around 5,000 miles). With regular check-ups, you’ll be giving your drive belt a great chance of reaching its maximum lifespan. Further, it will also keep you safer on the road and supporting the overall feel of your bike.
Often, bikers notice that their drive belt has gotten damaged due to rocks kicked up from the road. Such damages, alongside damage to the teeth and shredding that exposes the internal tensile fibers, could mean you should replace the drive belt before 100,000 miles of use. Harley-Davidson bike owners who remove the plastic belt cover for aesthetic purposes make a deliberate choice to shorten the lifespan of this part. If you choose to remove the cover, it’ll be a good idea to keep a close eye on the condition of the drive belt.
While rocks are often the most likely culprit, any sort of debris trapped in the belt could cause damage to the belt as well as the teeth. Frequent inspections and removal of this buildup could extend the lifespan of the drive belt. Cracking on the outside of the belt might also require earlier replacement.
