Components & Anatomy
This part of the excavator is responsible for moving the machine and provides stability on rough terrain.
What are the tracks?
During a walkaround, you should check this specific part of the track system for excessive wear or damage that could affect stability.
What is the undercarriage?
This type of excavator is preferred over wheeled versions because it provides better stability and traction on rough or soft terrain.
What is a tracked excavator?
This large, non-powered wheel at the front of the track frame helps guide the track and works with the tensioner
What is the Idler?
This common substance is pumped into a cylinder to move the idler forward and tighten the track
What is Grease?
This component, located in the center of every loader or excavator tire/track system, provides the final stage of gear reduction.
What is the final drive?
To check the tension of the tracks on an excavator, an operator can use the boom and bucket to do this.
What is lifting the machine off the ground?
This type of track system has the most ground contact.
LGP
This toothed wheel, usually located at the rear, engages the track links to propel the machine.
What is the Sprocket or drive gear
If an operator notices the sprocket teeth are becoming "hooked" or pointed, it is a sign of this
What is Excessive Wear (or Pitch Mismatch)?
This is the rotating platform of the excavator, which includes the seat and engine, and sits atop the track system.
What is the house?
This specialized tool is used by technicians to ensure the tracks are not too loose or too tight.
What is a track tension gauge?
this term identifies the component that helps carries the track over a long area.
Carrier roller
These internal components connect the track links and act as a hinge; they are often "sealed and lubricated" to reduce internal friction.
What are Pins and Bushings?
To properly measure track tension, the machine should be moved forward and stopped so the slack is on this part of the track.
What is the Top (between the sprocket and idler)?
These specific rollers are located at the bottom of the track frame to support the machine's weight and should be checked for debris buildup.
What are track rollers?
When performing a pre-operational check on a track-driven loader, you must ensure this is engaged before exiting the cab.
What is the parking brake?
This term is for the component that connects the chain together
Master link or master pin
This how to inspect the rollers in a track system
What is Pull the plug and check for the oil
This condition occurs when the track chain physically jumps off the rollers or idlers, often due to being too loose.
What is De-tracking?
This bearing on the rear axle allows the axle to move side to side, aiding in movement over uneven ground.
What is the trunnion bearing?
Debris buildup is most commonly found in these three areas of the track system during a walkaround.
What are the track rollers, engine compartment, and around pivot points?
this term is for the high rise parts on the shoe of the track
What is the grouser

Operating a machine primarily in this direction can cause significantly faster wear on the bushings and sprocket.
What is Reverse?
