Clark DPR20, DPR25, DPR30 Diesel Rough Terrain Lift Truck Parts Manual (DPR-1 5645_1st Rev)

These DPR20–DPR30 rough-terrain diesels work in mud, gravel, yards, and construction sites where parts get beat up and swapped around over the years. This parts manual is what I use to match what I’m seeing on the truck with the correct Clark part numbers, especially when someone’s already modified or “repaired” it. If, for example, the accelerator linkage is sloppy or bent and you’re not sure which lever, rod, or bushing is actually wrong, this book lets you trace each piece in the assembly and order exactly what you need instead of guessing.

Applications & Use Cases

Confirm the exact variant of a component when similar-looking parts are used across DPR20, DPR25, and DPR30.
Trace assemblies like accelerator pedals, linkages, and gauges to see how subcomponents relate before you start ordering.
Cross-check superseded or updated parts so you don’t reorder an obsolete or mismatched item.
Verify hardware and small fittings during teardown, so every washer, pin, and bracket goes back the way Clark intended.
Prepare accurate parts lists before a downtime window, reducing backorders and return shipments.

FAQ

Q: Can I use this on a tablet at the jobsite?

A: Yes, it works well digitally; you can zoom in on the diagrams to match small parts and keep the manual clean and accessible.

Q: Is it worth printing certain pages?

A: I usually print the assemblies I’m working on so I can mark them up with notes and part choices right at the truck.

Safety Note

Always lock out the truck, secure raised components, and follow proper lifting practices before inspecting or removing any parts.
