Overview#
The Winco DR175F4 is a 175 kW standby / 167 kW prime diesel generator powered by an FPT Industrial N67 TE2 6.7-liter six-cylinder turbocharged diesel engine with a Stamford alternator. The largest diesel standby unit in Winco's DR series — the flagship of their enclosed diesel standby line. Three-phase-only (277/480V) output. EPA Tier III certified (standby). 100% US-made in Le Center, Minnesota.
At 175 kW, the DR175F4 is the upper limit of Winco's diesel standby range. It represents the full capability of Winco's US manufacturing platform — the most powerful generator they produce, still built entirely in Le Center.
The American Manufacturing Advantage#
The 175 kW class is where US manufacturing origin becomes genuinely rare. Cummins, Caterpillar, Kohler, and MTU all use overseas engine platforms or mixed-origin assemblies at this output level. The DR175F4 is assembled in the US with an FPT Industrial N67 TE2 engine (CNH Industrial) and a Stamford alternator — both globally non-proprietary.
For federal agencies, DoD contractors, and healthcare systems subject to Buy American Act requirements, the DR175F4 provides 175 kW of qualifying US-manufactured standby infrastructure. Engine service goes through CNH Industrial's global dealer network (Case IH, New Holland, Iveco). Alternator service uses standard Stamford parts available through multiple supplier networks.
Service & Maintenance#
Oil and fuel filter changes every 500 hours or annually. At 6.7 liters of displacement, the N67 TE2 six-cylinder has a larger oil capacity and higher consumable cost than smaller platforms — factor this into lifecycle maintenance budgets. Annual fuel filter changes are mandatory for standby units regardless of hours, as diesel fuel degrades in storage tanks.
The Stamford alternator requires periodic brush inspection, bearing lubrication, and insulation testing — standard commercial generator maintenance. Transfer switch contacts should be exercised weekly. Major overhaul at 20,000 hours.
Our Service Experience#
PowerGen services Winco DR units throughout the Bay Area and Northern California. At 175 kW, the DR175F4 is in a class where Cummins and Caterpillar dominate. Winco's value is specific: US manufacture and non-proprietary components for projects where that matters more than brand recognition or connected monitoring features. The FPT Industrial N67 TE2 and Stamford components are serviced through the same commercial generator supply chains we use on all major diesel standby platforms — no specialized Winco dealer required.
