Worked Solution & Example Answer: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
Step 1
State TWO results of failure to conduct routine maintenance on belt drive systems.
Answer
- Tear on the belt: Regular wear and tear due to lack of maintenance can lead to breaks or failures in the belt.
- Overheating of components: Insufficient maintenance can result in increased friction and overheating of parts, leading to potential system failure.
Step 2
Give TWO reasons why the viscosity of a cutting fluid must be low.
Answer
- To allow it to flow easily: A low viscosity ensures that the cutting fluid can circulate throughout the system without hindrance, promoting effective cooling.
- Prevent excessive load on pump: Low viscosity reduces the effort needed by the pump to circulate the fluid, preventing strain on the pump system.

Step 4
Step 5
State TWO functions of an automatic transmission fluid.
Answer
- Transmit power in the torque convertor: It helps in transferring power from the engine to the transmission system, allowing smooth gear shifts.
- Acts as a heat transfer medium: It also acts to cool the transmission by transferring heat away from it, thus prolonging its lifespan.
Step 6
Explain the procedure to replace the belt in a V-belt drive system of a drill press.
Answer
- Switch off the machine: Ensure that the drill press is powered down and disconnected from the power source.
- Release tension on the belt: Loosen the adjustment screw or the set screw to reduce the tension on the belt.
- Remove the old belt: Carefully take off the belt from the pulleys.
- Install the new belt: Place the new belt around the correct pulleys, ensuring it matches the prior configuration.
- Re-tension the belt: Adjust the tension back to the required specification and ensure proper alignment before re-energizing the machine.
