Introduction
This examination is designed to assess the foundational knowledge and practical competencies
required of a first-period Heavy Equipment Technician apprentice in Alberta. The test evaluates
understanding of core trade concepts including workplace safety, tool identification, fastener
applications, lubrication principles, and power transmission systems. Questions are presented in a
multiple-choice format and include both theoretical inquiries and scenario-based problems that
reflect real-world shop conditions. Successful candidates will demonstrate the ability to apply
technical information, follow regulatory standards, and make sound decisions in maintenance and
repair contexts. This assessment emphasizes critical thinking and the practical application of trade
knowledge essential for professional competence.
SECTION ONE: QUESTIONS 1–100
1. What is the minimum acceptable PPE requirement when entering a heavy equipment shop
floor?
A. Safety glasses and steel-toed boots
B. Safety glasses, steel-toed boots, and hard hat
,C. Safety glasses, steel-toed boots, hard hat, and high-visibility vest
D. Safety glasses and hard hat
🟢 C. Safety glasses, steel-toed boots, hard hat, and high-visibility vest
🔴 Explanation: The minimum PPE for shop floor entry includes safety glasses, steel-toed boots,
hard hat, and high-visibility vest as per Alberta OHS regulations to ensure visibility and protection
from overhead and foot-level hazards.
2. Which type of wrench is designed to apply torque to fasteners without slipping off the bolt
head under high load?
A. Open-end wrench
B. Box-end wrench
C. Combination wrench
D. Flare-nut wrench
🟢 B. Box-end wrench
🔴 Explanation: Box-end wrenches have closed ends that fully surround the fastener head,
providing greater grip and reducing the risk of slipping under high torque, unlike open-end
wrenches.
3. An engine oil sample has been sent for analysis. A technician observes that the TBN (Total
Base Number) has dropped below acceptable levels. What does this indicate?
A. The oil has been contaminated with coolant
B. The oil's ability to neutralize acids is reduced
C. The viscosity has increased due to soot loading
D. The oil has been contaminated with fuel
🟢 B. The oil's ability to neutralize acids is reduced
🔴 Explanation: TBN measures the oil's reserve alkalinity to neutralize acidic combustion by-
products. A drop indicates depletion of this ability, requiring an oil change to prevent acid damage
to engine components.
4. When using a hydraulic press to remove a bearing, which safety procedure is most critical to
prevent injury?
A. Wearing rubber gloves
B. Using the correct size pressing tool
C. Ensuring the workpiece is securely centered
D. Standing to the side while applying pressure
🟢 D. Standing to the side while applying pressure
, 🔴 Explanation: Standing to the side ensures that if the workpiece or tool fails under pressure, the
operator is not directly in the trajectory of flying debris, preventing serious injury.
5. What does the thread designation "1/2-13 UNC" indicate?
A. 1/2 inch diameter, 13 threads per inch, Unified Fine
B. 1/2 inch diameter, 13 threads per inch, Unified Coarse
C. 13 mm diameter, 1/2 threads per inch, Unified Coarse
D. 1/2 inch diameter, 13 threads per inch, National Coarse
🟢 B. 1/2 inch diameter, 13 threads per inch, Unified Coarse
🔴 Explanation: "1/2" is the nominal diameter in inches, "13" is the threads per inch, and UNC
stands for Unified National Coarse thread series.
6. A technician lubricates a sealed bearing with grease. What is the most important
consideration regarding the amount of grease applied?
A. Fill the entire bearing cavity to prevent contamination
B. Apply grease until it purges from the seal, then stop
C. Grease quantity is not critical for sealed bearings
D. Fill to approximately 70-80% of the bearing cavity
🟢 D. Fill to approximately 70-80% of the bearing cavity
🔴 Explanation: Overfilling can cause excessive heat and seal damage; underfilling leads to
inadequate lubrication. Filling to 70-80% allows for proper lubrication while leaving room for
thermal expansion.
7. What is the function of the relief valve in a hydraulic system?
A. To direct fluid to the actuator
B. To prevent cavitation in the pump
C. To limit maximum system pressure
D. To filter contaminants from the fluid
🟢 C. To limit maximum system pressure
🔴 Explanation: The relief valve protects the system by diverting fluid back to the reservoir when
pressure exceeds a predetermined safe limit, preventing damage to components.
8. Which of the following is a symptom of a loose or worn fan belt?
