Clark DTT30 Towing Tractor Parts Manual (X171)

This DTT30 towing tractor usually spends its life shuttling trailers around plants, warehouses, and loading docks, so downtime hits material flow right away. This parts manual helps you positively identify every component on the machine so you can order the right bits the first time. For example, if a trailer tug comes in with a cracked engine mount or a damaged fuel line bracket, this book lets you match what you see on the frame to the correct Clark part number, instead of guessing from memory or photos.

Applications & Use Cases

• Trace how an assembly breaks down into brackets, fasteners, and subcomponents before you start teardown.
• Verify which exact version of a mount, hose, or linkage your DTT30 uses when parts have changed over the years.
• Cross‑reference old or superseded numbers from the tractor to the current orderable part.
• Compare similar components side by side to avoid mixing left/right or early/late styles during reassembly.
• Print just the relevant pages to carry to the tractor for tagging parts as you remove them.

FAQ

Q: Can I use this manual on a tablet in the shop?

A: Yes, it works well digitally so you can zoom in on drawings and search part descriptions by keyword.

Q: Is it still worth printing pages?

A: Many techs print the specific assemblies they’re working on so they can mark notes and keep them next to the machine.

Safety Note

Always lock out the tractor and secure any towed equipment before inspecting or removing parts.
