CAT 7.1 Engine

Connected to CAT ET — all parameters matched factory specs: fuel rail pressure, turbo boost, regen cycles, etc. No injector deviation. Engine is clean, responsive, and meets EU Stage V emissions. Highly recommended for fleets.

Works on forestry equipment. Fuel use is very low, and DEF consumption is minimal. Engine delivered sealed with all sensors included. Quiet operation even under full load. Definitely OEM.

We put this 7.1 in a road grader. The engine works 10+ hours daily without overheating. Very stable performance, fast throttle response. Clean install and zero warning lights. Great upgrade from the previous 3056.

Engine installed in a CAT loader. Everything connected as standard. Very economical, no smoke, quieter than older models. ECU worked out of the box. Excellent modern engine.

Runs our wheel loader on a grain terminal. Easy cold starts, zero smoke, and stable RPM under hydraulic load. Very quiet engine — operators love it. Diagnostics showed no errors after 80+ hours.
