The Ultimate Guide to SBC Cam Bearing Installation: A Step-by-Step Approach

Are you looking to upgrade the performance of your SBC (small block Chevrolet) engine? Installing new cam bearings is a crucial step in ensuring optimal camshaft operation and engine longevity. Our comprehensive guide will navigate you through the essential steps and provide valuable insights to empower you for a successful sbc cam bearing install.

Benefits of SBC Cam Bearing Installation

• Improved Oil Circulation: New cam bearings enhance oil flow to the camshaft, reducing friction and wear.
• Enhanced Durability: Properly installed cam bearings extend the lifespan of the camshaft and other engine components.
• Increased Performance: By minimizing friction and ensuring proper camshaft alignment, cam bearings contribute to increased engine power and efficiency.

Getting Started

• Gather Tools and Materials: Acquire the necessary tools, including a cam bearing installer, dial indicator, and micrometer, along with new SBC cam bearings.
• Prepare Engine Block: Clean the engine block thoroughly to remove any debris or contaminants. Ensure that the cam bearing bores are free of burrs or damage.

Tips for SBC Cam Bearing Installation

• Use a Dial Indicator: Measure the cam bearing bore diameter using a dial indicator to determine the correct bearing size.
• Lubricate Bearings: Apply a thin layer of engine oil to the outer surface of the cam bearings before installation.
• Install Bearings: Insert the cam bearings into the bores using a cam bearing installer, ensuring proper alignment and seating.

Common Mistakes to Avoid

• Incorrect Bearing Size: Using the wrong bearing size can lead to improper oil flow and premature bearing failure.
• Over-Lubrication: Excessive lubrication can attract debris and interfere with proper bearing operation.
• Improper Installation: Mishandling or incorrect installation can damage the cam bearings or bores.

FAQ About SBC Cam Bearing Installation

1. What is the recommended torque for SBC cam bearings? The recommended torque for SBC cam bearings typically ranges between 100-120 ft-lbs.
2. Can I install cam bearings without removing the cylinder heads? It is generally not recommended to install cam bearings without removing the cylinder heads, as it can be difficult to ensure proper alignment and seating.
3. How often should I replace SBC cam bearings? Cam bearings typically last for the life of the engine but may need to be replaced if the engine overheats or experiences excessive wear.

Step-by-Step SBC Cam Bearing Installation Guide

Materials:
- Cam bearing installer
- Dial indicator
- Micrometer
- New SBC cam bearings
- Engine oil

Steps:

1. Prepare Engine Block
   - Clean the engine block thoroughly using a solvent and brush.
   - Inspect the cam bearing bores for any burrs or damage. If any are found, use a hone to smooth the bore surface.

2. Measure Bearing Bore Diameter
   - Insert the dial indicator into the cam bearing bore and set it to zero.
   - Rotate the bore using a wrench or socket and record the minimum and maximum diameter readings.
   - Calculate the average diameter by adding the minimum and maximum readings and dividing by 2.

3. Select Cam Bearings
   - Choose cam bearings with an inner diameter that is within 0.0005 inches of the calculated average bore diameter.
   - Ensure that the cam bearings are of the correct width and type for your specific engine application.

4. Lubricate Bearings
   - Apply a thin layer of engine oil to the outer surface of the cam bearings.

5. Install Bearings
   - Insert the cam bearings into the bores using a cam bearing installer.
   - Ensure that the bearings are properly seated and flush with the bore surface.

6. Verify Installation
   - Re-measure the cam bearing bore diameter using the dial indicator to ensure that the bearings are installed correctly.
   - The measured diameter should be within 0.0005 inches of the calculated average bore diameter.

7. Torque Cam Bearings
   - Torque the cam bearings to the recommended specifications using a torque wrench.

8. Lubricate Cam
   - Apply a generous amount of engine assembly lube to the camshaft before installing it into the engine block. This will help to prevent premature wear during engine startup.
