CAT340

The C9.3B engine is more powerful than the 2020 336 engine.

Productivity is increased by up to 10% through increased power to the pump, a wider undercarriage and heavier counterweight.

Power, Smart and Eco modes are available to suit the type of job. Power mode always delivers maximum power. Smart mode automatically matches engine and hydraulic power to digging conditions, delivering maximum power when needed and reducing power when not needed to save fuel. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.

Designed for harsh conditions

Reinforced structures ensure long-term durability in harsh environments.

As standard, the excavator can operate in ambient temperatures up to 52° C (125° F) and start from cold as low as -18° C (0° F).

An optional battery-powered engine heater enables cold-weather starting in temperatures as low as –32° C (–25.6° F).

Automatic hydraulic oil preheating helps you get the job done faster in cold weather and helps extend component life.

Grease seals between track pins and bushings reduce travel noise and keep debris out, extending undercarriage life.

Easy to maintain

Expect lower maintenance costs with 1,000-hour engine oil change intervals.

Change all fuel filters after 1,000 hours of synchronization. Oil filters are grouped and mounted on the right side of the machine for easy maintenance.

Check hydraulic system oil and drain fuel system and tank water easily from ground level.

Hydraulic oil filter has excellent filtration performance, and the reverse drain valve keeps the oil clean between filter changes.

High-efficiency hydraulic fan with optional auto-reverse function removes debris from the core without operator intervention.

Ground-level S∙O∙SSM sampling port simplifies maintenance and allows for quick and easy oil sampling for analysis.
