1. Location & Associated SystemSystem: Drivetrain / Manual Transmission System (የማርሽ ሳጥን / ጊር ቦክስ).Exact Location: It supports the front end of the input shaft (often called አልቤሮ locally), which connects the engine clutch disk directly to the gearbox.2. Main FunctionSmooth Rotation: It allows the input shaft to spin smoothly at high speeds under heavy loads with minimal friction. Shaft Support & Alignment: It holds the input shaft in precise alignment while transferring rotational energy (torque) from the engine through the clutch into the gearbox gears.
