Properly mounted and secure. No visible leaks.
What should be checked regarding the Frame?
Not cracked or broken or missing frame bolts.
Supports all of apparatus body and mechanical components.
What is the purpose of the Transmission Fluid Canister?
Access to transmission fluid with dipstick and fill.
Ensure cap is secure with locking tabs.
What type of batteries are mentioned?
Maintenance-free type, no caps. Electrolyte is in gel form.
No bulging or visible leaks. Recommended not to disconnect because of electronic programming.
What does the Coolant Reservoir contain?
Clear, plastic container housing radiator coolant.
Properly mounted and secure. Not cracked or broken including cap. No visible leaks and cap secure.
What is contained within the Brake Canister?
Contains brake actuator.
Not leaking, cracked, or dented, and are mounted securely. See that there are no loose or missing clamps.
What is the function of Brake Hoses/Lines?
Provides air from tanks.
Check for cracked, worn, or frayed hoses and that all couplings and fittings are secured and not leaking.
What is a Rotor in the context of brakes?
The rotating part of the disc brake assembly of wheel.
The brake pads clamp down on the rotor to stop the wheels from spinning. Check for cracks, contaminates such as debris or oil/grease.
What does the Push Rod do?
Moves the slack adjuster.
Check that it is securely mounted. Look for broken, loose, or missing parts. No more than 1” play (pull it by hand).
What is the function of the Slack Adjuster?
Adjusts the brakes.
Check that it is securely mounted, is at a 90-degree angle. Look for broken, loose, or missing parts.
What is a clevis and pin?
Fastener between slack adjuster and push rod.
Ensure proper measurement per manufacturer settings.
What is the function of brake pads/linings?
Creates stopping friction against rotor in disc brake system.
Must be properly mounted and secure, with minimum thickness of ¼” where visible and no excessive grease or oil in the area.
What is engine oil used for?
To lubricate pistons as they are pushed into combustion chamber and return.
It is a black viscous liquid.
What is the purpose of radiator coolant?
To absorb heat generated by running engine.
It can be green, yellow, or red watery liquid.
What is automatic transmission fluid (ATF) used for?
To lubricate gears in transmission.
It is a red, semi viscous liquid.
What is diesel exhaust fluid (DEF)?
Used to neutralize emissions otherwise harmful to environment.
It is a clear, colorless, non-hazardous liquid like water with a slight odor of ammonia.
What is the function of the Air Governor?
Controls brake air system minimum (Cut-In) pressure and maximum (Cut-Out) pressure.
What should be checked regarding the Air Governor’s installation?
Properly mounted and secure. Check fittings for air leaks.
What is the primary role of the Air Compressor?
Responsible for supplying air to the brake system.
What considerations should be made for the Air Compressor?
Properly mounted and secure. No audible air leaks.
What is the purpose of the Engine Oil Fill?
Access to add engine oil.
What should be ensured about the Engine Oil Fill cap?
Make sure cap is secure with locking tabs.
What does the Fuel Filter do?
Removes foreign particles as well as water.
What considerations are needed for the Fuel Filter?
Properly mounted and secure. No visible leaks.
What is the function of the Oil Filter?
Removes foreign objects from lubrication oil systems.
What considerations should be made for the Oil Filter?
Properly mounted and secure. No visible leaks.
What does the Power Steering Canister hold?
Power steering fluid.
What should be checked regarding the Power Steering Canister?
Properly mounted and secure. Ensure cap is secure and proper fluid levels.
What is the primary function of the Transmission?
Moves power from the engine to the wheels through the drivetrain.
What components are included in the drivetrain?
- Drive shaft
- Differential
- Axles
- Wheels
What considerations should be made for the Transmission?
Properly mounted and no visible leaks.
What is the role of the Upper and Lower Control Arms (“A” Arms)?
Keep the apparatus and the wheels aligned and moving in unison.
What additional function do the Control Arms serve?
Helps to stabilize movement.
What considerations should be made for the Control Arms?
Properly mounted and secure. No cracks.
