Link Belt D250, D300 Tier1 and Tier2 Articulated Truck Shop Manual

These D250 and D300 articulated trucks spend their lives hauling heavy loads in quarries, earthmoving jobs, and muddy sites where access is rough and breakdowns are expensive. This shop manual is what I’d pull out when we’re doing serious work on one of these units—anything from chasing a driveline vibration to tearing down a leaking axle. For example, if a truck starts pulling to one side under load, this book walks you through a logical teardown and inspection path so you don’t just throw parts at it.

Applications & Use Cases

• Plan a full teardown of major components so you strip only what’s needed and avoid backtracking.
• Trace hydraulic or brake faults step by step, isolating valves, lines, and actuators in a sensible order.
• Inspect wear points on suspension, articulation joint, and drivetrain with clear checkpoints so you can decide repair vs. replace.
• Align and adjust linkages after repairs so steering, dumping, and braking respond correctly under load.
• Verify reassembly—seal faces, routing of hoses and harnesses—before you send the truck back into production.

FAQ

Q: Can I keep this manual on a tablet in the field?

A: Yes, it’s practical to use digitally; you can zoom diagrams and search text while working beside the truck.

Q: Is it worth printing sections?

A: Many techs print the pages for the job they’re on, mark them up with notes, and keep them in the service file for future reference.

Safety Note

Always lock out, block, and relieve stored energy on the truck before following any repair steps from this manual.
