This 12-phase procedure uses the ATC J47372 puller to safely remove fuel injectors from Detroit Diesel 60 Series engines. Ensures straight extraction without damage to injector or head bore.

Introduction: Essential Injector Removal for Detroit 60 Series Engines

Safe injector extraction preserves head integrity. The ATC J47372 puller provides controlled force—critical for professional results.

Phase 1-3: Preparation & Setup

1. Secure engine and relieve fuel pressure – Safety stands
2. Remove rocker/valve cover – Access injectors
3. Disconnect fuel lines – Drain residual
4. Inspect injector area – Note carbon/seizure
5. Prepare ATC J47372 puller – Verify fit

Phase 4-6: Injector Extraction

4. Engage puller on injector – Secure grip
5. Apply steady pulling force – Straight out
6. Extract injector carefully – No twisting
7. Inspect bore & injector – Check damage
8. Clean injector bore – Remove carbon
9. Repeat for all injectors – Consistent

Phase 7-9: Post-Removal

Phase 10-12: Testing & Finalization

10. Start idle test – Monitor leaks/noise
11. Load test engine – Verify performance
12. Final inspection – Clean/no leaks
13. Schedule follow-up – At 1,000 miles
