To check and replace the drive chain tensioner on a Harley-Davidson motorcycle, you'll need a few tools and follow the steps outlined below. Please note that the specific process may vary depending on the model and year of your motorcycle, so always consult your owner's manual or a professional mechanic for detailed instructions.
Tools you may need:
- Socket set with various sizes
- Torque wrench
- Chain tensioner tool (if required)
- Screwdrivers
- Allen wrenches
- Bike stand or lift (optional, but recommended)
Here's a general overview of the process:
Prepare your motorcycle: Ensure that your bike is on a stable and level surface. If you have a bike stand or lift, it will make the process easier and safer.
Locate the drive chain tensioner: Refer to your owner's manual or service manual to identify the location of the drive chain tensioner on your specific Harley-Davidson model. The tensioner is typically located near the rear wheel on the lower part of the swingarm.
Inspect the tensioner: Check the tensioner for any visible signs of wear, damage, or looseness. If the tensioner appears worn or damaged, it may need to be replaced. Also, check the tension of the drive chain itself.
Loosen the axle nut: Use a socket or wrench to loosen the axle nut on the rear wheel. You may need to consult your owner's manual to determine the correct size and torque specification for your specific motorcycle.
Adjust the tensioner: Harley-Davidson motorcycles usually have an automatic, self-adjusting tensioner. However, some models may have manual adjustments. If your bike has a manual tensioner, use the appropriate tool (e.g., chain tensioner tool) to adjust the tensioner according to the manufacturer's specifications. Follow the instructions provided in your owner's manual.
Check chain tension: With the tensioner adjusted, check the tension of the drive chain. You can do this by measuring the slack in the chain midway between the front and rear sprockets. Consult your owner's manual for the recommended chain slack measurement. Adjust the tensioner as needed to achieve the proper chain tension.
Tighten the axle nut: Once the tension is correctly adjusted, tighten the axle nut to the manufacturer's recommended torque specification using a torque wrench. This will secure the rear wheel and maintain the chain tension.
Test the tension: With the tensioner adjusted and the axle nut tightened, gently move the rear wheel up and down to check the chain tension. The chain should have a small amount of slack but should not be too loose or too tight. Make any final adjustments if necessary.
Remember, it's essential to refer to the specific instructions provided in your motorcycle's owner's manual or consult a professional mechanic who is familiar with Harley-Davidson motorcycles. They can provide you with accurate guidance based on your bike's model and year, ensuring proper maintenance and safety.
