Serviceability
Simplified service and maintenance saves time and money.
Designed with the service technician in mind, many service 
locations are at ground level so critical maintenance can be done 
quickly and efficiently. Longer maintenance intervals reduce 
cost and increase machine availability.
• Oil level gauge, oil filter, fuel filter and priming pump are on
the right side of the upper structure for easy maintenance.
• An optional electronic fuel water sensor is available to alert
the operator when the water level is high.
• Product Link assists with fleet management by tracking hours,
location and product health.
• New anti-skid plates over the top of the storage box and upper
structure help prevent slipping and mud from falling into the 
upper structure.
Sampling Ports
Equipped with S•O•S
SM
sampling ports and test ports for
hydraulics, engine oil and coolant for quick diagnostics. A test 
connection for the Cat Electronic Technician (Cat ET) service 
tool is now located in the cab. 
Air Cleaner
A double-layered filter core in the radial seal air filter gives 
more efficient filtration. A warning is displayed on the monitor 
when dust accumulates above a preset level. This filter is 
conveniently located in the compartment behind the cab. 
An optional pre-cleaner is also available to extend filter life 
and reduce maintenance costs.
Capsule Filter
Capsule-type, hydraulic return filter is accessible from outside 
the tank and prevents contaminants from entering the system 
when changing the hydraulic oil.
Radiator Compartment
Horizontal air conditioner condenser swings out for easy 
cleaning. Removable screens are located in front of the radiator 
and hydraulic cooler, reducing cleaning time and effort.
