8.1 State TWO results of failure to conduct routine maintenance on belt drive systems - NSC Mechanical Technology Welding and Metalwork - Question 8 - 2016 - Paper 1

1. To allow it to flow easily: Low viscosity ensures that the cutting fluid can easily circulate and reach all areas of the cutting surface, providing necessary cooling and lubrication.

2. Prevent excessive load on pump: Lower viscosity reduces the resistance the fluid faces in the pump system, allowing for efficient operation and avoiding unnecessary strain on equipment.

The flashpoint of a lubricant is defined as the lowest temperature at which the oil gives off a vapor that can ignite when exposed to an open flame. It is a critical property that indicates the safety and handling characteristics of the lubricant.

The abbreviation API stands for the American Petroleum Institute, which is an organization that represents the oil and gas industry in the United States.

1. Transmit power in the torque convertor: The automatic transmission fluid is essential for transferring power from the engine to the wheels, enabling smooth motion.

2. Acts as a heat transfer medium: It also helps to dissipate heat generated during operation, playing a vital role in maintaining optimal temperature throughout the transmission system.

1. Switch off and lock the machine: Ensure safety by turning off the power and locking the control to prevent accidental operation.

2. Release tension on the existing belt: Loosen the adjusting screw on the servo unit to relieve tension on the belt.

3. Remove the belt: Carefully detach the belt from the pulleys once the tension is released.

4. Install the new belt: Place the new belt around the correct pulley sequence, ensuring proper alignment and fit.

5. Re-tension the belt: Adjust the tension using the adjusting screw, ensuring it is tight enough to prevent slip but not so tight as to cause damage.
