harley primary chain

The primary chain on a Harley-Davidson motorcycle is a critical component that transmits power from the engine to the transmission. It is located inside the primary cover, which is on the left side of the bike.

It's important to keep the primary chain properly adjusted and lubricated to ensure smooth and efficient power transfer. Neglecting this maintenance can lead to excessive chain wear, noise, and even failure.

To adjust the primary chain, the primary cover must be removed to access the chain tensioner. The tensioner can be adjusted by turning the adjusting screw to achieve the recommended amount of slack in the chain. It's important to refer to the manufacturer's instructions for the specific model of Harley-Davidson, as different models may have slightly different procedures.

Lubrication of the primary chain is also important to prevent excessive wear and reduce noise. Harley-Davidson recommends using a high-quality primary chaincase lubricant that meets their specifications. The lubricant should be changed at regular intervals according to the manufacturer's recommendations.

If you are experiencing excessive noise or other issues with your primary chain, it's best to consult with a qualified mechanic or refer to the manufacturer's service manual for proper diagnosis and repair.
