Effective Strategies, Tips, and Tricks
Proper Installation: Follow the manufacturer's instructions for correct bearing installation to ensure proper alignment and longevity.
Use Quality Bearings: Invest in high-quality LS cam bearings from reputable manufacturers to maximize durability and performance.
Check Bearing Clearance: Use a dial indicator to measure cam bearing clearance and adjust as per specifications to optimize oil flow.
Use Proper Lubrication: Apply a thin film of high-performance camshaft assembly lube to bearings before installation to reduce friction and wear.
Common Mistakes to Avoid
Incorrect Bearing Size: Using the wrong bearing size can lead to excessive clearance or binding, damaging the camshaft and bearings.
Unclean Surfaces: Failure to clean mating surfaces before installation can introduce contaminants that can accelerate wear.
Overtightening Bearings: Excessive torque can damage bearings and cause premature failure. Follow the specified tightening sequence and torque values.
Basic Concepts
- Cam Bearing Journal: The cylindrical surface on the camshaft that fits inside the cam bearing.
- Bearing Bore: The hole in the engine block where the cam bearing is pressed in.
- Bearing Clearance: The difference between the cam bearing journal and bearing bore diameters, allowing for proper oil flow and lubrication.
Getting Started with LS Cam Bearings
- Disassemble: Remove the camshaft, timing chain, and associated components.
- Inspect: Inspect the camshaft journals and bearing bores for wear or damage.
- Measure: Use a dial indicator to measure cam bearing clearance.
- Select: Choose the appropriate LS cam bearings based on the measured clearance.
- Install: Press or install the new bearings into the block using the proper tools and techniques.
By understanding the basics, selecting the right LS cam bearings, and following best practices, you can ensure optimal engine performance and longevity. Invest in quality components and seek professional assistance when necessary to get the most out of your LS engine.
