Harley Pushrod Basics
Harley-Davidson motorcycles are known for their unique engine design. One important part of this design is the pushrod. Understanding pushrods is crucial for any Harley owner. They play a key role in the engine’s performance.
Understanding Pushrod Function
Pushrods are long, slender rods in the engine. They connect the camshaft to the rocker arms. This connection helps control the opening and closing of the valves. The camshaft pushes the pushrod, which then moves the rocker arm. This action opens and closes the valves at the right time. Properly adjusted pushrods ensure your engine runs smoothly and efficiently.
Types Of Pushrods In Harley Models
Harley-Davidson motorcycles use different types of pushrods. Here are the main types:
- Solid Pushrods: These are made from a single piece of metal. They are durable and strong.
- Adjustable Pushrods: These can be adjusted for length. They offer more flexibility during maintenance.
- Hydraulic Pushrods: These use hydraulic lifters. They automatically adjust to ensure optimal performance.
Each type of pushrod has its own advantages. Choosing the right pushrod depends on your bike’s model and your riding style. Always refer to a Harley Pushrod Adjustment Chart for accurate adjustments.
