In this guide, we’ll walk you through everything you need to know about the 2009 FXSTC drive belt tension, how to use the right tools, troubleshoot problems, and ensure your bike remains in top condition.
Understanding the 2009 FXSTC Drive Belt System
The 2009 Harley-Davidson FXSTC uses a belt drive system rather than the more traditional chain or shaft drive system. The benefits of a belt drive system include reduced maintenance, increased reliability, and a smoother ride. However, despite these advantages, the system still requires periodic maintenance, especially when it comes to the belt’s tension.
Components of the Drive Belt System
To fully appreciate the importance of belt tension, it’s helpful to understand the components involved:
- Drive Belt: This is the rubber component that transfers power from the engine’s crankshaft to the rear wheel. The FXSTC uses a reinforced rubber belt that is both durable and efficient.
- Pulleys: The front and rear pulleys guide the belt around the system. They play a crucial role in keeping the belt properly aligned.
- Tensioner: The tensioner maintains the correct tension on the drive belt by automatically adjusting as the belt stretches over time.
- Adjusters: These are the components that allow you to manually adjust the tension of the belt by shifting the position of the rear wheel.
- Rear Wheel: The rear wheel itself is where the final power transfer happens. The axle is adjusted to fine-tune the tension of the belt.
While the belt drive system on the FXSTC is relatively low-maintenance, it’s important to regularly inspect the tension and make adjustments to ensure that everything operates smoothly.
Why Drive Belt Tension Matters
Maintaining the correct tension on your FXSTC’s drive belt is essential for several reasons:
1. Improved Performance
A properly tensioned belt ensures efficient power transfer from the engine to the rear wheel. If the belt is too loose, it can cause power loss, leading to sluggish acceleration and poor performance.
2. Reduced Wear and Tear
Both an excessively tight or loose belt can lead to premature wear. A belt that is too tight can cause excessive friction, resulting in faster degradation of the rubber. On the other hand, a loose belt may result in it slipping, leading to unnecessary stress on the transmission.
3. Better Ride Comfort
When the belt is correctly tensioned, the bike will operate smoothly, with less vibration and noise. This makes for a more comfortable and enjoyable ride.
4. Longevity of the Belt
If properly adjusted and maintained, the drive belt can last for tens of thousands of miles. Incorrect tension, however, can reduce the life expectancy of the belt.
5. Safety Concerns
An improperly tensioned belt can result in slipping, which may cause a sudden loss of power while riding. In extreme cases, a broken belt can leave you stranded on the road.
How to Measure and Adjust Drive Belt Tension
Ensuring that your 2009 FXSTC has the correct belt tension involves two main steps: measuring and adjusting.
Tools You Will Need
- Drive Belt Tension Tool: The best tool for measuring the tension of your belt. A digital tension gauge or mechanical tension tool will provide an accurate reading of the deflection.
- Torque Wrench: This ensures that you tighten bolts to the manufacturer’s specifications. Over-tightening or under-tightening can lead to problems.
- Socket Set and Wrenches: These will be needed for loosening the axle nut and adjusting the tensioner.
- Motorcycle Lift or Stand: Lifting the motorcycle will take the weight off the rear wheel, making the process of adjusting the tension much easier.
- Ruler or Measuring Tape: For quick measurements of belt deflection if you don’t have a dedicated tension tool.
Step-by-Step Guide to Measuring and Adjusting the Belt Tension
- Lift the Rear of the Bike: Use a motorcycle lift or jack to elevate the rear end of the bike. This will allow you to easily access the drive belt.
- Locate the Belt: On the 2009 FXSTC, the drive belt is located on the right side of the bike. It connects the engine to the rear wheel and runs over a pair of pulleys.
- Measure the Belt Deflection:
- For accurate results, use a drive belt tension tool. The tool will give you an exact reading of the belt’s tension.
- Alternatively, use a ruler to measure the amount of deflection. Press gently in the center of the belt, and it should move about 1/2 inch to 3/4 inch. If it doesn’t, it’s time to adjust the tension.
- Adjust the Belt Tension:
- Locate the rear axle adjuster bolts. These are usually located on either side of the rear wheel.
- Using a wrench, loosen the locknuts on both sides of the rear axle adjusters.
- Turn the adjusters to move the rear wheel forward or backward. Tighten the adjusters if the belt is too loose or loosen them if the belt is too tight.
- Check the tension again with the measuring tool or ruler.
- Tighten the Components: Once the correct tension is achieved, tighten the locknuts on the adjusters. Then, torque the rear axle nut to the specified settings, which are typically found in your motorcycle’s owner’s manual.
- Test Ride: After adjusting the belt, take the bike for a short test ride to ensure that it runs smoothly. Pay attention to any unusual vibrations, noises, or slipping.
