What does CBM stand for?
- A.
Condition Based Maintenance
- B.
Component Based Maintenance
- C.
Computer Based Maintenance
- D.
Condition Based Management
Correct Answer
A. Condition Based MaintenanceExplanation
CBM stands for Condition Based Maintenance. This term refers to a maintenance strategy that involves monitoring the condition of equipment or assets in order to determine when maintenance should be performed. By using various techniques such as data analysis, sensors, and predictive models, CBM aims to optimize maintenance activities and reduce costs by performing maintenance only when necessary based on the actual condition of the equipment. This approach helps to prevent unexpected failures and maximize the lifespan of assets.Rate this question:

What 2 factors are used to create a graph based on a CBM algorithm?
- A.
Hours of operation and driver inspection records
- B.
Hours of operation and incident of failure
- C.
PM Records and driver inspection records
- D.
Human decided risk factor and incident of failure
Correct Answer
B. Hours of operation and incident of failureExplanation
A graph based on a CBM (Condition-Based Maintenance) algorithm is created using two factors: hours of operation and incident of failure. The hours of operation provide information on the usage and workload of the system, while the incident of failure indicates the frequency and severity of malfunctions or breakdowns. By analyzing these two factors, the CBM algorithm can determine the optimal maintenance schedule and identify potential issues before they escalate into major failures, thus improving the overall reliability and performance of the system.Rate this question:

When creating a fleet specific maintenance program the only guidelines you need to follow are OEM service guidelines.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When creating a fleet specific maintenance program, it is not sufficient to only follow OEM service guidelines. While these guidelines provide important recommendations, it is also necessary to consider other factors such as the specific needs and conditions of the fleet, industry standards, regulatory requirements, and the expertise of maintenance professionals. Ignoring these additional factors may result in an ineffective maintenance program that fails to address the unique requirements of the fleet. Therefore, the statement that the only guidelines needed are OEM service guidelines is false.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given answer is true because the statement mentions that there is a list of over 20 different items on the driver post-trip inspection sheet, which includes various components of the vehicle such as brakes, air compressor, frames, fifth wheel, fuel system, steering, and suspension. This indicates that the statement is accurate and there are indeed more than 20 items listed on the inspection sheet.Rate this question:

In addition to a pre-trip inspection, what else must drivers review?
- A.
Cargo
- B.
Last inspection record
- C.
Previous maintenance reports
- D.
Previous repairs performed
Correct Answer
B. Last inspection recordExplanation
Drivers must review the last inspection record in addition to conducting a pre-trip inspection. This is important to ensure that any issues or concerns identified during the previous inspection have been addressed and resolved before the driver starts their trip. Reviewing the last inspection record helps to maintain the safety and integrity of the vehicle and ensures that any necessary repairs or maintenance have been completed.Rate this question:

In which step of the inspection procedure should the driver look for fluid leaks?
- A.
Step 1
- B.
Step 4
- C.
Step 5
- D.
Step 8
Correct Answer
A. Step 1Explanation
In Step 1 of the inspection procedure, the driver should look for fluid leaks. This is the initial step where the driver examines the vehicle for any signs of leakage, such as oil, coolant, or brake fluid. By checking for fluid leaks at the beginning of the inspection, the driver can identify any potential issues that may require immediate attention or maintenance before operating the vehicle.Rate this question:

Which of the following should be checked in the 2nd step [engine compartment] of the pre-trip inspection procedure?
- A.
Coolant level
- B.
Alternator belts
- C.
Brake pads
- D.
Power steering fluid
- E.
Engine hood clearance
Correct Answer(s)
A. Coolant level
B. Alternator belts
D. Power steering fluidExplanation
In the 2nd step of the pre-trip inspection procedure, the following should be checked in the engine compartment: coolant level, alternator belts, and power steering fluid. These components are important for the proper functioning of the vehicle and should be inspected to ensure they are in good condition before starting a trip. Checking the coolant level helps prevent overheating of the engine, inspecting the alternator belts ensures they are not worn or damaged, and checking the power steering fluid ensures smooth steering control.Rate this question:

Scrubbed or polished areas on either side of the lug might indicate:
- A.
Wheel bearing failure
- B.
Uneven lug torque
- C.
Rim slippage
- D.
Low tire pressure
Correct Answer
C. Rim slippageExplanation
Scrubbed or polished areas on either side of the lug might indicate rim slippage. This means that the rim has moved or shifted, causing friction between the lug and the rim. This could be due to loose lug nuts or improper installation of the wheel. When the rim slips, it can cause the lug to rub against the surrounding area, resulting in scrubbed or polished marks.Rate this question:

Fleet maintenance standards should be higher than CVSA standards.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Fleet maintenance standards should be higher than CVSA (Commercial Vehicle Safety Alliance) standards because fleet maintenance standards are specific to a particular fleet and take into account the unique requirements and conditions of the fleet's vehicles. CVSA standards, on the other hand, are general standards that apply to all commercial vehicles. Therefore, to ensure the highest level of safety and efficiency, fleet maintenance standards should exceed the minimum requirements set by CVSA.Rate this question:

Heat and use alter the________ properties of lubricants.
Correct Answer
chemicalExplanation
Heat and use can cause changes in the chemical properties of lubricants. When a lubricant is exposed to high temperatures, it can undergo chemical reactions such as oxidation or thermal degradation, which can alter its composition and performance. Additionally, the mechanical action of using lubricants can also lead to chemical changes, such as the breakdown of additives or the formation of reaction products. These chemical alterations can affect the lubricant's ability to reduce friction, prevent wear, and provide adequate lubrication, ultimately impacting its overall effectiveness.Rate this question:

A higher SAE rating indicates the oil has a higher______and will flow more.
Correct Answer
viscosity
slowlyExplanation
A higher SAE rating indicates that the oil has a higher viscosity and will flow more slowly. Viscosity refers to the thickness or resistance to flow of a fluid. Therefore, if the oil has a higher viscosity, it means it is thicker and will flow more slowly.Rate this question:

Automatic greasing systems dispense grease using a______valve.
Correct Answer
meteringExplanation
Automatic greasing systems dispense grease using a metering valve. A metering valve is a device that controls the flow rate of grease being dispensed. It ensures that the correct amount of grease is delivered to the desired location, preventing over-lubrication or under-lubrication. The metering valve allows for precise control and distribution of grease, ensuring optimal lubrication for the equipment or machinery.Rate this question:

As water is reduced in the coolant solution, it's the ability to dissipate heat is increased.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
As water is reduced in the coolant solution, its ability to dissipate heat is not increased. In fact, the opposite is true. Water has a higher heat capacity compared to other components in the coolant solution, such as antifreeze. Therefore, reducing the amount of water in the coolant solution would actually decrease its ability to dissipate heat effectively.Rate this question:
