The Ultimate Guide to Installing Cam Bearings in Small Block Chevrolets
Installing cam bearings is a crucial step in any small block Chevrolet (SBC) engine build. These bearings play a vital role in supporting the camshaft and ensuring proper oil flow to the valvetrain. A precise installation is essential to prevent premature wear and failure.
Effective Strategies for Installing Cam Bearings
Use the Correct Bearing Size: Refer to the camshaft manufacturer's specifications for the appropriate bearing size. Using the wrong size can lead to improper fit and accelerated wear.
Clean the Block and Bearings: Thoroughly clean the cam bearing saddles and the bearings themselves to remove any oil, debris, or burrs. This ensures a proper fit and prevents contamination.
Lubricate the Bearings: Apply a thin layer of engine oil or assembly lube to the bearings before installing them. This reduces friction and helps ensure a smooth installation.
Install the Bearings Squarely: Use a bearing installer or a hammer and socket to gently tap the bearings into place. Ensure they are seated squarely and flush with the block surface.
Check the Fit: Once the bearings are installed, check their fit by rotating the camshaft through the bearings. The camshaft should rotate smoothly without any binding or excessive play.
Tips for Success
| Tips | Benefits |
|---|---|
| Use high-quality bearings | Reduced wear and improved durability |
| Measure the bearing bores | Ensures precise fit and prevents improper installation |
| Use a bearing alignment tool | Ensures accurate positioning of the bearings |
| Tighten the bolts evenly | Distributes load evenly and prevents bearing damage |
| Run the engine for a break-in period | Allows the bearings to wear in properly and extend their lifespan |
Common Mistakes to Avoid
| Mistakes | Consequences |
|---|---|
| Using worn or damaged bearings | Premature wear, reduced oil flow, and engine failure |
| Installing bearings improperly | Leaks, excessive play, and premature failure |
| Overtightening the bolts | Cracked bearings, distorted block, or damaged camshaft |
| Neglecting to lubricate the bearings | Increased friction, wear, and potential seizure |
| Failing to break in the engine | Accelerated wear and reduced bearing lifespan |
Success Stories

Getting Started
Installing cam bearings in an SBC engine is a straightforward process if you follow these steps:
- Remove the camshaft and old bearings.
- Clean the cam bearing saddles and bearings.
- Lubricate the bearings.
- Install the bearings using a bearing installer or a hammer and socket.
- Check the fit of the bearings by rotating the camshaft.
- Tighten the bearing bolts evenly.
- Run the engine for a break-in period.
Challenges and Potential Drawbacks
- Precision: Installing cam bearings requires precision to ensure a proper fit. Improper installation can lead to premature wear, oil leaks, and engine damage.
- Bearings Quality: Using high-quality bearings is crucial for durability and performance. Cheap or low-quality bearings may fail prematurely.
- Alignment: The cam bearings must be aligned accurately to prevent binding or excessive play.
- Break-In Period: Neglecting to break in the engine properly can accelerate bearing wear and reduce their lifespan.
Industry Insights and Maximizing Efficiency
- According to the Society of Automotive Engineers (SAE), proper install cam bearings sbc is essential to maintain proper oil flow to the valvetrain, reducing friction and wear.
- Using a cam bearing alignment tool can improve accuracy and reduce the risk of misalignment.
- High-performance engines may require specialized cam bearings designed to handle higher loads and operating conditions.
