Takeuchi TKB72-S Hydraulic Hammer Service Manual

A TKB72-S hammer spends its life breaking concrete, rock, and hard ground in dust, vibration, and temperature swings, so it takes a beating itself. This service manual is what I use to trace hydraulic faults, confirm wear limits, and walk through teardown and reassembly without guessing. If, for example, the hammer starts hitting weak or intermittently, this book helps me verify oil supply, isolate whether the issue is in the carrier or the hammer, then check internal components in a logical order before I replace anything expensive.

Applications & Use Cases

• Diagnosing weak or no blow by following step-by-step checks to separate hydraulic supply problems from internal hammer faults.
• Confirming wear and clearances on key parts so you know if they can be reused or must be replaced.
• Guiding disassembly and reassembly to avoid damaged seals, misaligned parts, or trapped air.
• Verifying correct tool installation and bushing condition to prevent side-loading and premature failures.
• Tracing leaks and pressure loss so you fix the root cause, not just the symptom.

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 terms while working next to the machine.

Q: Should I still print pages from it?

A: I usually print the specific procedures and torque charts I need that day, so they don’t get my tablet covered in oil and dust.

Safety Note

Always isolate hydraulic pressure and support all components securely before loosening any fittings or fasteners.
