Pre-Installation Preparation
Before installing S&S Adjustable Pushrods, gather necessary tools and ensure the engine is prepared. Disconnect the battery to prevent accidental starter engagement and ensure safety.
2.1 Tools and Materials Needed
To install S&S Adjustable Pushrods, you’ll need a set of basic tools, including wrenches, sockets, and a torque wrench. Additionally, petroleum jelly is recommended for lubricating components during assembly. Ensure all tools are in good condition to avoid damage to the pushrods or engine parts. Having a clean, well-lit workspace is also essential for a successful installation process.
2.2 Safety Precautions
Always disconnect the battery before starting installation to prevent accidental starter engagement. Wear protective gloves and eyewear to avoid injury from tools or debris. Ensure proper ventilation when handling petroleum jelly or lubricants. Never force tools onto components, as this could cause damage. Keep flammable materials away from the workspace. Follow all safety guidelines outlined in the manufacturer’s instructions to ensure a safe and successful installation process.
Installation Steps
- Disconnect the battery to prevent inadvertent starter engagement.
- Bring the cam to base circle for proper tappet adjustment.
- Install and adjust pushrods to achieve zero lash setting.
3.1 Disconnecting the Battery
Disconnecting the battery is the first step in any installation process to ensure safety. This prevents accidental engine start-up and potential injury. Locate the negative terminal, usually marked with a negative sign (-) or colored black. Use an appropriate wrench to loosen the nut and slide the connector off the terminal. Secure the connector away from the battery post to avoid reconnection. This simple step ensures a safe working environment.
3.2 Bringing the Cam to Base Circle
Bringing the cam to base circle is essential before adjusting pushrods. Rotate the engine using a wrench on the crankshaft to position the cam lobes at their lowest point. This ensures the valves are closed and lifters are at rest. Visually confirm the cam is at base circle to prevent incorrect measurements. Proper alignment ensures accurate pushrod adjustment and avoids potential engine damage. This step is critical for achieving the correct zero lash setting.
3.4 Securing the Pushrods
Securing the pushrods involves tightening them to the recommended torque specification to ensure proper alignment and prevent movement. Use a torque wrench to tighten the pushrod locks gradually, verifying each pushrod’s length and alignment with lifters and rocker arms. Double-check the pushrod length by rotating the engine to ensure smooth operation without binding. Apply threadlocker to the threads for added security against vibration-induced loosening. Tighten in a specific sequence, such as front to back, to maintain even pressure and avoid misalignment. Avoid over-tightening to prevent damage to threads or components.
Adjusting the Pushrods
Adjusting S&S pushrods involves setting the correct length to achieve zero lash, ensuring proper valve train operation. Rotate the engine to bring the cam lobe to base circle, then adjust the pushrod length until no play is felt. Use a wrench to tighten the locknut securely after achieving the desired adjustment. Always refer to the manufacturer’s specifications for precise guidance.
4.1 Understanding Zero Lash Adjustment
Zero lash adjustment ensures the pushrod length is set so there is no play in the valve train, providing precise operation. Rotate the engine to bring the cam lobe to its base circle. Adjust the pushrod length until it contacts the valve bucket without any clearance. This setting prevents excessive wear and ensures optimal engine performance. Use a wrench to tighten the locknut securely after achieving zero lash, following the manufacturer’s guidelines for accurate adjustment.
4.2 Checking Pushrod Rotation
After setting zero lash, manually rotate the engine to ensure the pushrods spin freely without binding. A smooth rotation indicates proper adjustment and alignment. If the pushrod does not rotate, check for obstructions or over-tightening. Proper rotation ensures even wear and prevents damage to the valve train. Use a wrench to verify the pushrod’s movement, ensuring it operates seamlessly with each engine cycle. This step is crucial for maintaining optimal engine performance and longevity.
Troubleshooting Common Issues
Identify and address issues like pushrod binding or improper lash settings. Ensure correct adjustment and lubrication to maintain smooth engine operation and prevent potential damage.
5.1 Pushrods Not Spinning Freely
If pushrods are not spinning freely, inspect for debris or tight adjustments. Clean and lubricate with petroleum jelly to ensure smooth operation. Check for proper installation and alignment, as misalignment can cause binding. Verify that pushrods are adjusted to zero lash and rotate freely without resistance. If issues persist, consult the manufacturer or a professional mechanic to avoid further complications. Proper lubrication and alignment are crucial for maintaining optimal performance and preventing potential engine damage.
5.2 Achieving Proper Pushrod Length
Proper pushrod length ensures accurate valve train geometry and prevents engine damage. Use a dial indicator to measure lash and adjust pushrods to achieve zero lash. Rotate the engine to ensure consistent measurements across all cylinders. If pushrods are too long or short, adjust accordingly to maintain optimal performance. Incorrect length can lead to poor engine operation or damage. Always refer to manufacturer specifications for precise measurements and adjustments to ensure reliability and peak performance.
Maintenance and Care
Regular lubrication of moving parts ensures smooth operation. Apply petroleum jelly to oil pumps for quick pressure. Periodically check pushrod length and rotation to maintain optimal performance and prevent wear.
6.1 Lubrication Tips
Proper lubrication is essential for maintaining the performance and longevity of S&S Adjustable Pushrods. Apply a small amount of petroleum jelly to the oil pump before reassembly to ensure quick oil pressure. Regularly inspect and lubricate all moving parts, such as the pushrod ends and rocker arms, to prevent wear and ensure smooth operation. This practice helps maintain optimal engine performance and reduces the risk of mechanical failure over time.
6.2 Periodic Adjustments
Regular adjustments of S&S Adjustable Pushrods are crucial to maintain proper valve train alignment and engine performance. After initial installation, check and adjust pushrods every 1,000 to 3,000 miles or as needed. Start by rotating the engine to the base circle, then set pushrods to zero lash for optimal operation. Periodic checks ensure consistent performance and prevent potential issues such as excessive wear or misalignment, keeping your engine running smoothly over time.
Safety Guidelines
Always disconnect the battery before starting work to prevent accidental starter engagement. Use petroleum jelly for oil pump components to ensure proper sealing and function. Stay safe!
7.1 Avoiding Inadvertent Starter Engagement
Disconnecting the battery is crucial to prevent accidental starter engagement during pushrod installation. This step ensures no sparks or unintended engine starts occur while working. Always remove the negative terminal first to eliminate power sources. Following this precaution safeguards both the technician and the engine from potential damage or injury, ensuring a safe working environment throughout the adjustment process.
7.2 Handling Petroleum Jelly for Oil Pumps
When working with oil pumps, apply petroleum jelly to ensure proper lubrication and sealing. Remove the top plate carefully, then pack the pump with a generous amount of jelly before reassembling. This method helps achieve oil pressure quickly and effectively. Always handle petroleum jelly with clean tools to avoid contamination. Proper application ensures smooth engine operation and prevents potential damage to internal components during the adjustment or installation process of S&S Adjustable Pushrods.
