Effective Strategies for LS Main Bearing Clearance

Precision Measurement: Utilize calibrated gauges to obtain precise measurements.

Thorough Cleaning: Remove all contaminants prior to bearing installation.

Proper Lubrication: Apply ample oil to bearings and adjacent surfaces.

Torque Inspection: Verify torque specifications for all connecting rod and main bolts.

Specialized Applications: Consult with experts for guidance on modified engines or racing applications.

Regular Maintenance: Monitor bearing wear and adjust clearances as necessary.

Common Mistakes to Avoid

Neglecting Measurement: Failure to precisely measure clearances can lead to catastrophic engine damage.

Overtightening Bolts: Excessive torque can distort bearing caps, compromising bearing clearance.

Ignoring Lubrication: Insufficient lubrication starves bearings, causing premature failure.

Mishandling Components: Rough handling or improper installation can damage bearings and compromise performance.

Delayed Maintenance: Neglecting regular inspections and maintenance accelerates bearing wear and reduces engine lifespan.

Incorrect Clearance Specifications: Deviating from recommended clearances can have severe consequences on engine performance and longevity.
