# Certified 150-Point Pre-Delivery Technical Inspection

> AgriVanguard Machinery guarantees the mechanical integrity and authenticity of every machine before it leaves our staging facilities.

## Inspection Scope & Protocol
Our team of certified heavy-equipment mechanics performs a systematic 150-point diagnostic audit:

1. Engine & Aftertreatment
   - Cold and hot start performance, blow-by evaluation, compression testing.
   - Oil laboratory sampling for metal particulate, coolant contamination, and soot.
   - Turbocharger shaft play, intercooler integrity, cooling system pressure check.
   - DPF (Diesel Particulate Filter), SCR (AdBlue/DEF), and EGR valve regeneration status.

2. Hydraulics & Hydrostatics
   - Main pump and auxiliary circuit pressure load testing against factory bar/PSI ratings.
   - Cylinder chrome rod condition, packing seals, and internal leakage checks.
   - Valve bank responsiveness, proportional control calibration, and oil cleanliness.

3. Powertrain & Transmission
   - Powershift, CVT (Vario/AutoPowr), and hydrostatic transmission calibration.
   - Clutch pack wear, differential lock actuation, 4WD drive engagement.
   - Front and rear axle planetary hubs, universal joints, and Kingpin play.

4. Undercarriage & Wheels
   - Crawler tracks: link pitch stretch, bushing wear, sprocket tooth profile, bottom and top carrier rollers.
   - Wheeled equipment: tire tread depth percentage, rim welds, and wheel bolt torque.

5. Cab, Safety & Electronics
   - Complete ECU fault code dump and diagnostics.
   - ROPS / FOPS cabin safety certification.
   - Slew ring gear backlash (for excavators and cranes).
   - Guidance systems: GPS receiver, ISOBUS terminals, and lighting circuits.

## Buyer Assurance
- Buyers receive the complete digital inspection report, oil lab results, and high-definition video demonstration before closing the contract.
