2. REFURBISHMENT PROCESS: 4-STEP QUALITY GATE SYSTEM

All units undergo sequential quality gates. Failure at any stage results in core rejection. No partial refurbishments are permitted.

STEP 1: ENGINE & GEARBOX TESTING (DYNOMETER & BENCH VALIDATION)

Objective: Quantify mechanical integrity and performance decay.

• Process:
• Cold soak (24h at 5°C) followed by hot-run SAE J1995 cycle.
• Emissions analysis (NOx, PM) per EPA 1065.
• Gearbox torque mapping under simulated load (0–100% in 10% increments).
• Ultrasonic crack detection on cylinder heads, blocks, and crankshafts.

Parameter	Test Method	OEM Threshold	SEA LION Standard
Max. Oil Consumption	Gravimetric (100h)	≤ 0.5% fuel	≤ 0.3% fuel
Blow-by Pressure	SAE J1757	≤ 60 CFM	≤ 45 CFM
Gearbox Shift Consistency	Torque Sensor Array	±8% tolerance	±4% tolerance
Crankshaft Runout	Dial Indicator (ISO 2768)	≤ 0.15mm	≤ 0.08mm

Outcome: Units failing ≥2 parameters are scrapped. Only 22% of intake cores pass Step 1 (2025 audit data).

STEP 2: CABIN REPAINTING (INDUSTRIAL COATING PROTOCOL)

Objective: Restore structural corrosion resistance and operator safety compliance.

• Process:
• Abrasive blasting (SA 2.5 standard) to bare metal.
• E-coat primer (75μm min. DFT) + epoxy mid-coat (50μm).
• Polyurethane topcoat (RAL 7040/7042, 60μm DFT) with UV stabilizers.
• Post-cure adhesion test (ASTM D3359, Class 5B required).

Critical Control: All weld seams and stress points receive double-coating. No touch-up paint permitted on structural zones (A-pillars, crossmembers).

STEP 3: NEW TIRES & BATTERY REPLACEMENT (OPERATIONAL READINESS)

Objective: Eliminate failure points in critical wear components.

Component	Specification	Validation Method
Tires	Michelin X Works XZL (11R24.5) Load Range G	Load/speed rating verification per ISO 4249
Battery	OPTIMA YellowTop (Group 31) AGM	Cold Cranking Amps (CCA) test (≥1000A)
Wheel Hubs	Re-torqued to 450 ft-lb (±5%)	Digital torque audit log

Note: Tires sourced exclusively from Tier-1 manufacturers; retreads prohibited. Batteries include 36-month pro-rata warranty.

STEP 4: CHASSIS REINFORCEMENT (CONSTRUCTION-GRADE UPGRADE)

Objective: Address fatigue in high-stress applications (e.g., dump trucks, crane carriers).

• Process:
• Ultrasonic thickness testing of frame rails (critical zones: kingpin mounts, suspension brackets).
• Weld-on reinforcement plates (ASTM A572 Grade 50, 8mm min. thickness) at stress risers.
• Post-weld stress relief (600°C soak, controlled cooling).
• Final load test: 150% GVWR static load for 30 minutes.

SEA LION Standard: Reinforcement mandatory if rail thickness < 7.2mm (vs. OEM 8.0mm spec). 98% of construction-sector units require this step.

2. Drain all fluids (oil, coolant, fuel)
3. Seal intake/exhaust ports with plastic caps

4. Apply desiccant packs inside air filter housing and valve cover

5. Securing in Transit

6. Flat rack: Lash with 5,000 kg WLL (Working Load Limit) straps, cradled on timber dunnage

7. Bulk: Nest in timber skids, segregated from abrasive cargo

8. Documentation

9. Include wax treatment certificate

10. Provide engine test run logs and corrosion inspection reports

11. Port Handling

12. Prioritize direct transfer from warehouse to vessel to reduce open-air exposure
13. Avoid open-deck storage in high-humidity zones

---

6. Conclusion

For the export of used truck engines from China, Flat Rack container shipping provides the optimal balance of protection, traceability, and industrial compliance. While bulk cargo offers lower upfront costs, it significantly increases corrosion and damage risk—especially without robust wax-based protection.

SEA LION International mandates wax spraying as a non-negotiable step in all engine export operations, regardless of shipping method. This protocol ensures compliance with international corrosion control standards and preserves residual asset value upon arrival.

Fleet managers and construction equipment recyclers are advised to prioritize Flat Rack logistics for high-reuse-intent engines and reserve bulk transport for scrap recovery programs only.
