Maximum power: 100 kW (134 hp) — Maximum torque: 550 Nm @ 1500 rpm (406 lb-ft @ 1500 rpm) — Rated speed: 2000–2200 rpm — Minimum power: 70 kW (94 hp) — Emissions: EU Stage V / U.S. EPA Tier 4 Final / Japan 2014 (Tier 4 Final)

Features At A Glance

• Low cost machine installation — ECM and aftertreatment sensors pre-installed; bespoke wiring harness included for simplified hookup. IOPU-mounted fuel filter with water-in-fuel sensor for straightforward low-pressure fuel system installation. Optional engine control panel available for monitoring and speed control.
• Industry leading flexibility — Multiple configurations for different machine types. Standard and heavy-duty options for radiator, air and fuel filtration. Electrical systems in 12V or 24V.
• Lifetime of low cost — Fuel consumption optimised for diverse off-highway cycles. Hydraulic tappets, multi-vee belts and 500‑hour service intervals reduce operating costs.
