SBC Cam Bearing Installation: A Step-by-Step Guide to Precision and Performance
Installing Small Block Chevy (SBC) cam bearings is a crucial step in ensuring the longevity and performance of your engine. With the right tools, technique, and a little bit of patience, you can achieve a professional-quality installation that will maximize your horsepower and prevent costly repairs down the road.
Benefits of Installing SBC Cam Bearings
- Reduced friction and wear: Worn or damaged cam bearings can cause excessive friction between the camshaft and the engine block, leading to premature wear and engine damage.
- Improved oil flow: Properly installed cam bearings ensure proper oil flow to the camshaft, reducing friction and heat buildup.
- Increased horsepower: Reduced friction and improved oil flow can result in noticeable horsepower gains, especially at higher RPMs.
How to Install SBC Cam Bearings
- Prepare the block: Clean the cam bearing bores in the engine block thoroughly and apply a thin layer of assembly lube.
- Lubricate the bearings: Apply a generous amount of assembly lube to the outside surface of each cam bearing.
- Install the bearings: Carefully align and press each cam bearing into its corresponding bore using a cam bearing installer or a suitable tool.
- Check the fit: Use a depth micrometer to measure the depth of each installed bearing. The bearings should be flush with the surface of the engine block.
- Secure the bearings: Use a bearing retainer or sealant to hold the bearings in place.
