Clark Clarktor 4530 – Lots 3250, 3251, 3391, 3710, 3765, 3815, 4140, 4185, 4440, 4441, 4530 Parts Manual (X147)

These Clarktor 4530 tugs spend their lives spotting aircraft and trailers around ramps, hangars, and warehouses, so when they’re down, everything backs up. This parts manual is what I use to match what I’m seeing on the tug to the correct Clark part numbers, especially across those different lot builds listed. For example, if I’m chasing a steering issue and find a worn linkage or bracket, this book lets me positively identify that exact piece and any related hardware so I don’t order the wrong variant.

Applications & Use Cases

• Confirm which parts fit your specific lot before placing an order, avoiding mismatched components.
• Trace assemblies—steering, brakes, drawbar, etc.—to see how subcomponents are grouped and named.
• Cross-check old or unreadable casting marks against the manual’s naming logic.
• Verify small items like pins, bushings, and seals during teardown so everything needed is on the same ticket.
• Compare similar-looking parts on multiple tugs and isolate the correct one by lot and configuration.

FAQ

Q: Can I use this on a tablet in the hangar or on the ramp?

A: Yes, you can keep the file on a tablet or laptop and zoom in on diagrams to verify parts right at the machine.

Q: Is it worth printing sections of this manual?

A: Many techs print the pages for the systems they’re working on so they can mark notes and part choices during teardown.

Safety Note

Always verify part compatibility and follow the tug’s safety procedures before returning it to service.
