This methodical approach‚ detailed in videos‚ ensures proper valve train function and optimal engine performance․
Preparing the Engine for Pushrod Installation
S&S instructions consistently highlight the importance of a clean working environment before beginning the installation process․ Thoroughly clean the area around the rocker boxes to prevent any contaminants from entering the engine․
Ensure the engine is cooled down completely‚ adhering to safety precautions․ Rotate the engine to Top Dead Center (TDC) on the compression stroke of the cylinder you’ll start with․ This positioning facilitates accurate pushrod installation and adjustment․
Remove the rocker boxes and inspect the lifters for any damage or wear․ Verify that the lifters are functioning correctly before proceeding․ Following these preparatory steps will contribute to a successful and trouble-free installation․
Installing the Pushrods
According to S&S instructions‚ begin by lightly oiling the pushrod ends to ensure smooth installation into the lifters and pushrod cups․ Carefully insert one end of the pushrod into the lifter‚ ensuring it seats fully․
Then‚ guide the other end of the pushrod into the rocker arm․ Repeat this process for each pushrod‚ working systematically through the engine․
Avoid forcing the pushrods; if resistance is met‚ re-check alignment and ensure the engine is at TDC․ S&S emphasizes a gentle approach to prevent damage․ Once all pushrods are in place‚ proceed to the adjustment phase‚ following their detailed guidelines․
Adjusting Hydraulic Lifters with S&S Pushrods
S&S instructions detail a crucial adjustment process after installing the pushrods․ With the engine off‚ rotate it until the lifter you’re adjusting is on the base circle of the cam․
Using the S&S adjustable pushrod‚ turn the adjuster until zero lash is achieved – meaning no play between the lifter and valve train․
From zero lash‚ tighten the adjuster an additional four full turns for stock-style hydraulic lifters‚ as per S&S recommendations․ This pre-load ensures proper lifter operation․ Repeat for each lifter‚ verifying proper oil flow throughout the process․
Adjustment Techniques
S&S instructions highlight the “4-turn” method for hydraulic lifters‚ while precise adjustments can be achieved utilizing a torque wrench for optimal valve train geometry․
The “4-Turn” Method
S&S instructions frequently reference the “4-turn” method as a baseline for adjusting hydraulic lifters with their adjustable pushrods․ This technique involves rotating the adjusting nut four full turns after the pushrod makes contact with the lifter cup․
This initial setting aims to establish proper preload‚ allowing the hydraulic lifter to function correctly and maintain valve train integrity․ However‚ it’s crucial to remember this is a starting point․ Further refinement might be necessary to eliminate valve train noise and ensure optimal performance․
Always consult the complete S&S documentation for specific engine applications‚ as variations may exist․
Using a Torque Wrench for Precise Adjustment
While the “4-turn” method provides a solid starting point‚ S&S instructions don’t explicitly mandate torque specifications for adjustable pushrod adjustment; However‚ experienced builders often employ a torque wrench for enhanced precision․
Applying a controlled torque ensures consistent preload across all lifters‚ minimizing variations that can lead to valve train noise or performance issues․ The ideal torque value depends on the specific lifter and pushrod combination‚ so referencing S&S documentation or consulting with a knowledgeable technician is vital․
Careful torque application contributes to a quieter‚ more reliable engine․
Troubleshooting Common Issues

When adjusting‚ avoid over-tightening‚ which can damage the lifters․ Monitor for any signs of lifter noise post-installation; this often indicates improper adjustment or insufficient oiling․ Remember that S&S pushrods are designed for use with stock-style hydraulic lifters‚ so maintaining their condition is vital for optimal performance and longevity․
Advanced Considerations
S&S instructions detail differences between solid and hydraulic lifter adjustments․ Camshaft profile significantly impacts pushrod adjustment; precise setup maximizes performance‚ following S&S guidelines․
Solid Lifter vs․ Hydraulic Lifter Adjustment
S&S instructions clearly differentiate adjustment procedures for solid versus hydraulic lifters․ Hydraulic lifters‚ commonly paired with S&S adjustable pushrods‚ require a pre-load adjustment – typically four turns past zero lash – to ensure proper operation and compensate for thermal expansion․
Solid lifters‚ conversely‚ demand precise zero-lash adjustment․ This involves meticulously tightening the pushrod until all valve train slack is eliminated‚ without introducing pre-load․ Incorrect adjustment can lead to valve float or damage․ Always consult S&S documentation for specific recommendations based on your engine configuration and lifter type․ Following these guidelines is crucial for optimal performance and longevity․
Impact of Camshaft Profile on Pushrod Adjustment
The camshaft profile significantly influences S&S adjustable pushrod adjustment․ Aggressive camshafts with higher lift and faster ramp rates necessitate more precise valve train geometry․ S&S instructions often emphasize the importance of verifying pushrod length to accommodate these profiles‚ preventing potential valve-to-piston interference․
Different cam designs require varying degrees of pre-load for hydraulic lifters․ Always refer to the camshaft manufacturer’s specifications alongside S&S guidelines․ Improper adjustment can lead to reduced performance‚ increased wear‚ or even engine damage․ Careful consideration of the camshaft’s characteristics is vital for a successful installation;
Safety Precautions
S&S instructions stress a completely cooled engine before starting․ Utilize proper tools carefully‚ avoiding injury․ Disconnect the battery during installation for added safety․
Always follow recommended procedures to prevent burns or mechanical issues during the adjustable pushrod process․
Engine Cool-Down Procedures
S&S instructions consistently emphasize the critical importance of allowing the engine to cool completely before commencing any work on the valve train‚ including adjustable pushrod installation․ A hot engine presents a significant burn hazard‚ and working on components at elevated temperatures can lead to inaccurate adjustments․
Ideally‚ allow several hours for the engine to cool naturally․ Avoid using water or forced air to accelerate the cooling process‚ as this can cause thermal shock and potentially damage engine components․ Ensure all exhaust components are cool to the touch before beginning․ Prioritizing a cool engine ensures both safety and accuracy throughout the installation and adjustment process․
Proper Tool Usage
S&S instructions highlight the necessity of utilizing the correct tools for adjustable pushrod installation and adjustment․ A torque wrench is crucial for achieving precise and consistent adjustments‚ preventing over-tightening or under-tightening of components․ Using properly sized wrenches and sockets minimizes the risk of damaging fasteners․
