Worked Solution & Example Answer:8.1 State TWO results of failure to conduct routine maintenance on belt drive systems - NSC Mechanical Technology Automotive - Question 8 - 2016 - Paper 1

Step 1

State TWO results of failure to conduct routine maintenance on belt drive systems.

96%

114 rated

Answer

Tear on the belt: Without regular checks, the belt may wear out or tear, leading to malfunction.
Misalignment of belt drive: Failure to maintain alignment can cause additional stress on components, leading to a breakdown.

Step 2

Give TWO reasons why the viscosity of a cutting fluid must be low.

99%

104 rated

Answer

To allow it to flow easily: Low viscosity ensures that the cutting fluid can circulate effectively, providing cooling and lubrication.
Dissipate excess heat: A low-viscosity fluid can better absorb and dissipate heat generated during machining processes.

Step 3

Define the term flashpoint of a lubricant.

96%

101 rated

Answer

The flashpoint of a lubricant is defined as the lowest temperature at which the oil emits enough vapor to ignite when exposed to a flame.

Step 4

What does the abbreviation API stand for?

98%

120 rated

Answer

API stands for American Petroleum Institute.

Step 5

State TWO functions of an automatic transmission fluid.

97%

117 rated

Answer

Transmit power in the torque convertor: The fluid facilitates power transfer in the transmission system.
Acts as heat transfer medium: It helps to transfer heat from the transmission to the outside, assisting in cooling.

Step 6

Explain the procedure to replace the belt in a V-belt drive system of a drill press.

97%

121 rated

Answer

Switch off the machine: Ensure that the machine is completely powered down.
Release tension on the belt: Loosen the adjusting screw to relieve tension on the belt.
Remove the old belt: Take the belt off its pulleys.
Install the new belt: Place a new belt on the correct pulleys.
Retighten and align: Adjust the tension and ensure that the belt is properly aligned before securing everything.
