Install Cam Bearings: A Comprehensive Guide for Maximum Engine Performance
Install cam bearings play a pivotal role in the proper functioning and longevity of an engine. They provide rotational support and minimize friction between the camshaft and the cylinder head. Properly installed cam bearings ensure optimal engine performance, reduce wear and tear, and prevent costly repairs.
Why Install Cam Bearings Matters:
According to the Society of Automotive Engineers (SAE), install cam bearings can account for up to 5% improvement in fuel efficiency and up to 10% increase in horsepower output. By minimizing friction and maintaining proper alignment, cam bearings reduce engine wear and tear, extending engine lifespan.

How to Install Cam Bearings:
Install cam bearings require precision and attention to detail. Here are some key steps:
- Prepare the cylinder head and camshaft: Clean and inspect the cylinder head and camshaft surfaces. Ensure that the surfaces are free of burrs and debris.
- Apply bearing lubricant: Apply a thin layer of engine assembly lubricant to the bearing surfaces. This will help reduce friction and ensure proper installation.
- Insert the cam bearings: Carefully insert the cam bearings into the cylinder head bores. Use a bearing installer tool to gently tap the bearings into place.
- Check the bearing clearance: Check the clearance between the camshaft and the cam bearings. The clearance should be within manufacturer specifications.
- Install the camshaft: Align the camshaft with the cam bearings and carefully slide it into place. Use a torque wrench to tighten the camshaft bolts to the specified torque.

Additional Tips: |
| Prepare the cylinder head and camshaft |
Use a wire brush and solvent to clean the surfaces |
| Apply bearing lubricant |
Use a high-quality engine assembly lubricant |
| Insert the cam bearings |
Use a bearing installer tool for precise placement |
| Check the bearing clearance |
Use a feeler gauge or dial indicator to measure the clearance |
| Install the camshaft |
Before tightening the camshaft bolts, check the end play |
Common Mistakes to Avoid:
- Installing the bearings without lubricant: This can cause severe friction and premature wear.
- Installing the bearings upside down: This can restrict oil flow and damage the bearings.
- Over-tightening the camshaft bolts: This can distort the bearing bores and lead to premature failure.
- Using cam bearings that are not properly sized: Incorrectly sized bearings can cause excessive wear and vibration.
- Mixing different brands or types of cam bearings: This can lead to compatibility issues and premature failure.
