What's in it

It starts with the removed unit drawings, dimensions, schedule and tools. Then the bare machine is positioned and the tire and wheel assemblies are fitted. The engine hood mirror and front cover come next.

The N2 gas in the front and rear suspensions is then adjusted, and there's a slinging procedure for lifting the truck. The last section gives the tail gate and payload meter specs, if fitted.

Suspension gas pressure affects both ride and stability when loaded, so it's worth getting right. Dealers and contractors use this guide on delivery and when a truck is moved by low-loader.

Good to know

The order of the steps matters more than it looks. Some parts have to go on before others to leave room for tools or slings, and the final checks confirm everything works before the machine is handed over. Following the guide as written avoids having to take something off again to get at a bolt behind it.

Before you buy

This is an assembly guide, not a repair manual. For troubleshooting and overhaul you'll want the machine's shop manual as well.
