Engine Rebuild Cam Bearings: Complete Installation Workflow Using M20060-03 Kit

Cam bearing installation is the moment of truth in any engine rebuild. Get it right, and your engine will last 500,000+ miles. Get it wrong, and you have a $4,000 block repair. The M20060-03 Cam Bearing Driver & Puller Kit removes all guesswork—complete workflow, pro tips, quality checks, and block protection inside.

The Bearing Installation Challenge: Pressure, Precision, Position

Every cam bearing installation must balance three critical factors:

• Pressure: Enough force to seat the bearing fully without damaging bore or bearing
• Precision: Bearing must be perfectly centered and square to bore
• Position: Each bearing must seat to exact OEM depth

The M20060-03 kit controls all three by using precision drivers and universal adapters that pilot on the bearing bore itself.

Complete Cam Bearing Installation Sequence

1. Inspect block thoroughly – Dial bore for runout, check for cracks, verify bore diameter.
2. Clean all bearing bores – Solvent wash, compressed air dry, wipe with clean cloth.
3. Stage bearings in order – Lay out all cam bearings by position (front to rear).
4. Select M20060-03 driver – Match driver size to bearing bore diameter.
5. Apply assembly lube – Light coat on outer bearing diameter only.
6. Place bearing in bore – Hand-position, ensuring no debris underneath.
7. Install driver sleeve – Center driver over bearing bore.
8. Press bearing home – Steady, even pressure until depth stop engages.
9. Verify installation – Check bearing is flush, flush, square to bore face.
10. Repeat for all positions – Follow OEM sequence; never skip a bearing.

Bearing Removal: Safe Extraction with M20060-03 Puller

When a rebuild requires bearing replacement or machine shop work, the M20060-03 puller bar safely extracts old bearings without scoring bores:

1. Insert puller bar under bearing at two opposite points (90° apart).
2. Apply steady, even pressure—pulling straight out perpendicular to block.
3. Go slowly—listen and feel for bearing to lift evenly.
4. Once bearing clears bore, remove and inspect bore for damage.
