Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Automotive and heavy equipment work involves fuel systems, hydraulics, high-voltage (in EV/hybrid vehicles), exhaust gases, and heavy loads. Knowing the safety protocols isn't just exam material — it's the difference between a routine job and a serious injury.
System: compressor 120-140 psi, air dryer removes moisture, main/service/emergency reservoirs. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Heavy equipment and vehicles are governed by federal and provincial regulations covering emissions, safety systems, weights and dimensions, and operator certification. Knowing these standards protects you legally and ensures the machines you service are roadworthy and safe.
Coupling: kingpin height critical (47.5 ± 0.5 inches); lock jaw must grip fully. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Vehicle systems use a wide range of specialty materials, fluids, and components that must meet OEM specifications. This section covers proper tool selection, component identification, and the material properties that determine service intervals and replacement requirements.
Slack adjuster: bridges S-cam and push rod; proper stroke critical (1.5-2.0 inches typical). On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Landing gear: lowers empty trailer, supports nose; check for rust, cracked welds. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
7-way: 12V, ground, left turn, right turn, brake, reverse, electric brake; pin-specific. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
