How We Test and Verify Every AM General Engine

Our used AM General engines are carefully inspected to ensure peak operational condition. Each unit undergoes a detailed process:

Visual inspection for external damage, oil leaks, or cracks
Compression testing on all cylinders
Mileage verification (when available)
Component testing (injectors, glow plugs, etc.)

We also classify engines by their generation, whether they are mechanical injection (older models) or electronically controlled (later models), so you get exactly what you need. Once an engine passes testing, it is cleaned, tagged, and securely prepped for shipment.

We’re here to support you every step of the way — from identifying the right model to post-installation troubleshooting.
