5. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ

ເຄື່ອງມືທີ່ຕ້ອງການ:

• Bottom bracket wrench compatible with external bearing cups
• wrench ແຮງບິດ
• Grease (lithium-based or specific bicycle grease)
• ລ້າງ rags ສະອາດ

ຂັ້ນ​ຕອນ​ການ​ຕິດ​ຕັ້ງ​:

1. ການກະກຽມ: 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.
2. ໃຊ້ນ້ຳມັນຫລໍ່ລື່ນ: 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.
3. 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.
4. 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.
5. ແໜ້ນຈອກ: 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.
6. ຕິດຕັ້ງຊຸດຂໍ້ຕໍ່: Follow your crankset manufacturer's instructions for installing the crank arms onto the bottom bracket spindle.
7. 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.

6. ການດໍາເນີນງານ

Once installed, the M-Wave Thread Bottom Bracket operates automatically as part of your bicycle's drivetrain. It should provide smooth, silent rotation of your crankset. Pay attention to any unusual noises or resistance during pedaling, as these may indicate a need for maintenance or inspection.

• ທໍາຄວາມສະອາດ: Periodically clean the exterior of the bottom bracket and surrounding frame area to prevent dirt and grime buildup.
• ການກວດກາ: Inspect the bottom bracket for any signs of wear, damage, or play. Check for smooth rotation by removing the chain and spinning the crank arms.
• ຣີເກຣasing: If creaking develops or after significant mileage, the bottom bracket cups may need to be removed, cleaned, re-greased, and reinstalled. This should be done by a qualified mechanic if you are not comfortable performing the task.
• ການທົດແທນລູກປືນ: If the sealed bearings feel rough or have excessive play, they may need to be replaced. This typically requires specialized tools and expertise.
