• Mandatory rejection triggers: Frame rail cracks, driveline vibration > 4.5 mm/s RMS, engine derate events > 3 during test.

---

4. RESIDUAL LIFE ASSESSMENT

Based on PDI data and maintenance history audit (min. 3 years documented):

Component	Typical Remaining Life	Critical Intervention Threshold
Chassis Frame	120,000–180,000 km	25% cross-section loss at any rail
Engine Core	20,000–35,000 operating hrs	Cylinder bore wear > 0.15mm
Tandem Axle Assemblies	80,000–120,000 km	Hub bearing play > 0.3mm

Note: Units with <10,000 km frame life or <15,000 hrs engine life are excluded from certification.

---

5. CONCLUSION

SEA LION-certified Hawo 6×4 Dump Trucks meet minimum operational viability thresholds for rough-terrain construction duty when:
– Chassis shows no critical fatigue damage per Section 2.1.
– Engine oil analysis and load tests comply with Section 2.2/3.2.
– Full PDI protocol (Section 3) is passed without critical failures.

Recommendation: Fleet managers should prioritize units with documented maintenance history and residual frame life >120,000 km. Engine rebuilds are economically viable up to 45,000 hrs; chassis replacement is cost-prohibitive beyond 200,000 km. Units passing this protocol deliver 85–92% of original design capability in controlled heavy-duty cycles.

3. Corrosion Protection: Wax Spraying Treatment

Marine environments expose metal surfaces to salt-laden air and condensation, accelerating corrosion—particularly on undercarriages, suspension components, and chassis rails of used dump trucks.

Recommended Protection Protocol:

• Wax-Based Corrosion Inhibitor: Application of a solvent-based, lanolin-enriched wax spray (e.g., Dinitrol LS 2000 or equivalent industrial standard).
• Coverage Areas:
• Chassis frame (inner rails, cross members)
• Suspension brackets and pivot points
• Wheel hubs and brake assemblies
• Exhaust system and fuel tank mounts
• Application Process:
• Thorough cleaning of salt, dust, and grease.
• Blow-dry critical cavities.
• Spray application using high-pressure gun (min. 30 psi).
• Allow 24-hour curing before loading.
• Performance:
• Provides up to 6 months of salt-spray resistance (ASTM B117 compliant).
• Self-healing film resists chipping during transport.
• Non-toxic and compliant with IMO marine environmental standards.

Note: Wax spraying is strongly advised for all shipping methods but is critical for Flat Rack and Bulk Cargo due to full exposure.

---

4. Method-Specific Recommendations
