Steering
All machines require wheel (or track) chocks and lock out / tag out when performing steering system work. An articulated steer machine also requires this
Properly installed and rated safety bar
This component controls lateral side to side movement of the axles
Pan hard rod
False
Electrical components are typically rated by this
Voltage and Amperage
The term for an injury caused by oil under pressure being embedded under the skin due to either close proximity to a leak, or cracking open a system without properly depressurizing first
Hydraulic Injection (serious injury)
This will determine the turning radius of the front tires in relation to the rear tires on a machine with two pivoting frame sections
Location of the articulation point
This controls the ride height of the cushion hitch
Linkage rod length on the levelling valve
These 3 organizations govern the standards for building and repairing ROPS and FOPS
This type of circuit has multiple paths for current to flow, sometimes referred to as a current divider circuit
Parallel
Both a flow meter (hydraulic) and ammeter (electric) work on the same principle, they must be connected to a circuit in this configuration
Series
A flow divider (control valve) on an articulated haul truck has this purpose in the steering circuit
Prioritize flow to the steering circuit over flow to the hoist circuit
This must be compensated for when charging an accumulator
Temperature
These protect the shanks from wear and damage when digging into the ground
Teeth or Points
These are connected in parallel between the CAN-HI & CAN-LO
120 ohm terminating resistors
This term describes how much a lubricants' viscosity will change with a change in temperature
Viscosity Index (VI)
The minimum number of drive circuit related pumps on a large hydrostatic machine
Three. 2 hydrostatic, and at least 1 charge.
With the bail down, the cushion hitch is in this position, and bowl is doing this
Lockdown. Loading.
On a new rope, this type of damage can lead to a weak spot and reduce the working strength of the rope
Kinking
After installing a splice clip this procedure must be done to complete the repair
Solder and Heat shrink
This test may be performed to help determine internal wear in a hydraulic pump
Flow loss test or Oil leakage test
The number, and names, of all the steering functions on a motor grader
Three; Front wheel steer, Articulation, and Wheel Lean
This suspension system allows for considerable movement, but the component which gives it it's name does not
Rubber block
This type of fire suppression agent is designed for class A, B, and C fires
Monoammonium phosphate (dry chemical)
This is the term for a panel illuminated by a single light source carried along thin plastic cores with a polymer optical cladding sheath.
Fiber Optic
When starting a troubleshooting (hydraulic, pneumatic, or electric) process, a technician should generally begin with this component.
Source of energy (Battery, Pump operation, Accum charge)
