The Ultimate Guide to Installing Cam Bearings in Your SBC

Installing cam bearings in your SBC (small block Chevy) is a crucial step in building a high-performance engine. These bearings provide support and alignment for the camshaft, ensuring optimal performance and longevity.

Why Installing Cam Bearings Matters

Cam bearings play a vital role in your engine's operation:

• Reduced Friction: Bearings reduce friction between the camshaft and the block, minimizing power loss and wear.
• Improved Alignment: Properly installed bearings ensure precise alignment of the camshaft, optimizing valve timing and engine performance.
• Increased Durability: Bearings protect the camshaft and other engine components from premature wear and failure.

How Installing Cam Bearings Benefits Your Engine

Investing in quality cam bearings offers numerous benefits:

• Enhanced Power Output: Reduced friction and optimal alignment contribute to increased horsepower and torque.
• Smoother Engine Operation: Reduced noise and vibration ensure a smoother, more responsive engine.
• Extended Engine Life: Proper bearing installation can significantly prolong the lifespan of your camshaft and other engine components.

Step-by-Step Cam Bearing Installation Guide

Installing cam bearings requires precision and attention to detail:

1. Prepare the Block:

• Clean the cam bearing bores thoroughly with brake cleaner and a lint-free cloth.
• Apply a thin film of engine assembly lube to the bores.

2. Align the Bearings:

• Lubricate the outside of the cam bearings with engine assembly lube.
• Align the bearings in their corresponding bores, ensuring they are flush with the block surface.

3. Tap the Bearings into Place:

• Use a bearing driver or socket to gently tap the bearings into place.
• Apply even pressure to avoid distorting the bearings or damaging the bores.

4. Check for Alignment:

• Install the camshaft in the bearings and check for proper alignment.
• Rotate the camshaft and inspect the bearing clearance.

5. Secure the Bearings:

• Use a lockplate or retaining ring to secure the bearings in place.
• Tighten the fasteners to the specified torque.

Tips and Tricks for Cam Bearing Installation

• Use a light touch when installing the bearings to avoid distorting them.
• Ensure the camshaft is properly lubricated before installing it.
• Check the bearing clearance with a feeler gauge after installation.
• Inspect the camshaft and bearings for any signs of wear or damage before reassembly.

FAQs

Q: What is the ideal cam bearing clearance?

A: The ideal cam bearing clearance will vary depending on the specific engine application. Consult your engine builder or refer to the manufacturer's specifications.

Q: Can I replace cam bearings without removing the engine?

A: It is possible to replace cam bearings without removing the engine, but it requires specialized tools and experience. It is generally recommended to have this work performed by a qualified mechanic.

Q: How often should I replace cam bearings?

A: Cam bearings typically do not need to be replaced frequently unless there are signs of wear or damage. Regular oil changes and proper engine maintenance can extend their lifespan.

Q: What is the recommended torque for cam bearing fasteners?

A: The recommended torque for cam bearing fasteners will vary depending on the type of bearing and fastener used. Consult the manufacturer's specifications or a qualified mechanic.

Q: Can I use aftermarket cam bearings?

A: Aftermarket cam bearings can be used as long as they meet the specifications of the original equipment manufacturer (OEM). Genuine OEM bearings are often recommended for optimal performance and reliability.
