This 12-phase procedure uses the ATC 9996966 hold-down tool to securely clamp cylinder liners during head service and rebuilds on Volvo D9, D12, D13 engines. Prevents lift and ensures proper alignment.

Introduction: Essential Liner Hold-Down for Volvo Engine Service

Secure liner clamping prevents movement when heads are off. The ATC 9996966 tool provides stable hold—critical for accurate reassembly.

Phase 1-3: Preparation & Engine Access

1. Secure engine/block – Stand or frame
2. Remove head & related components – Expose liners
3. Inspect liner position – Note any lift
4. Clean flange area – Remove debris
5. Prepare ATC 9996966 tool – Check condition

Phase 4-6: Liner Clamping & Hold-Down

4. Position hold-down tool – Over liner flange
5. Clamp securely – Even pressure
6. Verify no movement – Test stability
7. Perform head/block service – With liner held
8. Check clamp during work – No loosening
9. Document clamping – Photos/setup

Phase 7-9: Reassembly Preparation

Phase 10-12: Testing & Finalization

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