What Clarke Power Services does

Clarke Power Services, Inc. is a Cincinnati-headquartered, privately held commercial vehicle service company founded in 1964. It operates as an authorized service center for major OEMs including Detroit Diesel, Allison Transmission, MTU, Perkins Engines, and Mercedes-Benz truck engines, providing Class 4–8 truck repair, parts distribution, warranty administration, preventive maintenance, and mobile on-site service. Operations are organized across five divisions: core Service/Parts/Warranty, Vehicare Fleet Solutions (preventive maintenance with VAMS asset management and VCP customer portal), Clarke PowerGen (generator and fire pump engine service), Clarke Heavy Duty (vocational equipment refurbishment), and Government Services (federal/military and state/local contracts). The business also operates technician training centers in Wentzville, MO and Knoxville, TN.

The company generates revenue through professional services (billable labor for repair and PM), hardware sales (200,000+ parts inventory across OEM brands), warranty claim pass-through, fee-based technical training, refurbishment services, and long-term government contracts (up to 5 years). Go-to-market is enterprise field sales with 10 territory sales managers, 20 customer support managers, 100+ customer support representatives, and a direct service footprint of 20 shop locations and 150+ mobile service trucks across 9 states. Government sales alone approach $20M annually, with the WheelTime network of 16 partner providers extending reach to nearly 200 locations across all 50 states and Canada.

Clarke Power Services is part of a broader Clarke Worldwide family that includes Clarke Fire Protection Products, Inc. and related entities. The company appears family-operated with no disclosed institutional investor ownership, and operates wholly-owned subsidiaries aligned with each service division. Recent strategic emphasis is on capacity expansion (new Greensboro facility), hybrid/electrified vehicle service capability (Allison eGen Flex training), and engine distribution growth (24-state Perkins footprint), while exiting the glider business following EPA regulatory changes.
