Takeuchi TKB1702-S Hydraulic Hammer Parts Manual (PMTKB1702-XENG.B21)

Hydraulic hammers like the TKB1702-S live a hard life—demo work, trenching, rock breaking, usually in dust, mud, and cold starts. This parts manual helps you trace every component in that hammer, from the housing down to the last seal, so you can order the right bits the first time. Picture this: hammer’s dead, you crack it open, find a chewed-up snap ring in the valve stack—this book lets you isolate that ring, match the exact part number, and verify what else you should replace while you’re in there.

Applications & Use Cases

• Track down the correct part number when you’ve got three similar-looking bushings on the bench and don’t want to guess.
• Break the hammer into sub-assemblies so you can route teardown and rebuild work in a clean order—housing, accumulator, main valve, then small hardware.
• Check which seals, pins, and spacers usually get replaced together, so you can stock smart and avoid waiting on a $2 part.
• Verify superseded parts when the dealer says “that number’s old,” and you want to be sure it’ll still align and fit your specific TKB1702-S.
• Use the exploded views to inspect your layout and test your reassembly sequence before you start driving pins and bleeding the carrier hydraulics.

FAQ

Q: Is this a PDF I can search on my laptop in the shop?

A: Yes, it’s typically a searchable PDF, so you can jump by part name or section instead of flipping pages.

Q: Can I print just the pages I need to take out to the jobsite?

A: Usually, yes—you can print selected pages, stick them in a sleeve, and keep the original file clean on your computer.

Safety Note

Always depressurize and lock out the carrier’s hydraulic system before you crack lines or pull the hammer apart, or you’re asking for a high-pressure fluid injury.
