Quizplus · Accepted Answer

Heating the gear to the manufacturer's specified temperature allows it to expand slightly, making it easier to install onto the shaft. Once it cools down, it contracts and fits snugly onto the shaft, ensuring a secure installation without the need for excessive force that could damage the components. Cooling the shaft or heating both the shaft and gear are not standard practices for this process.
