5. Enstalasyon ak Enstalasyon
Zouti obligatwa:
- Bottom bracket wrench compatible with external bearing cups
- Kle koupl
- Grease (lithium-based or specific bicycle grease)
- Netwaye ranyon
Etap enstalasyon:
- Preparasyon: Ensure the bottom bracket shell threads on your bicycle frame are clean and free of debris. It is recommended to chase and face the bottom bracket shell if you have the tools, though not always strictly necessary for new frames.
- Aplike grès: Apply a thin, even layer of grease to the threads of both the bottom bracket shell on the frame and the threads of the bottom bracket cups. This prevents seizing and reduces creaking.
- Install Drive Side Cup: Identify the drive-side (right-hand side) bottom bracket cup. Thread it into the drive-side of the frame's bottom bracket shell. Most threaded bottom brackets use a standard English thread (BSA), meaning the drive-side cup threads counter-clockwise (left-hand thread) and the non-drive side threads clockwise (right-hand thread). Start threading by hand to avoid cross-threading.
- Install Non-Drive Side Cup: Thread the non-drive side (left-hand side) bottom bracket cup into the non-drive side of the frame's bottom bracket shell. Thread clockwise by hand.
- Sere gode yo: Use your bottom bracket wrench to tighten both cups. Refer to the torque specifications provided by your crankset manufacturer or general bottom bracket torque recommendations (typically 35-50 Nm). Use a torque wrench for accurate tightening.
- Enstale Crankset la: Follow your crankset manufacturer's instructions for installing the crank arms onto the bottom bracket spindle.
- Adaptor Rings (if applicable): If your bottom bracket housing is 73-78 mm, ensure the included adaptor rings are correctly installed according to the instructions provided with the rings or your crankset.
