2. Тос түрхэх: 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. Хөтчийн хажуугийн аяга суурилуулах: 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.

5. Tighten Cups: 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. Crankset суулгах: Follow your crankset manufacturer's instructions for installing the crank arms onto the bottom bracket spindle.
