Pielstick Motorlar
AB Defence supplies and supports Pielstick heavy-duty engines with a full range of procurement, integration, and technical services. We help defense infrastructure and strategic logistics fleets maintain continuous power generation, reliable rail traction, and extended lifecycle performance for legacy assets
Pielstick Engine Solutions: Powering Strategic Rail Logistics & Industrial Defense Infrastructure
In the defense sector, operational capability extends beyond the frontline; it relies heavily on the logistical backbone and energy security of military installations. SEMT Pielstick engines have long been the prime movers for heavy-duty locomotives transporting military hardware and industrial generators powering remote bases. ABS Defence understands the critical nature of these legacy systems. We provide a specialized supply chain for Pielstick PA and PC series engines, ensuring that the “Railway & Industrial” assets supporting your mission remain operational, efficient, and reliable against obsolescence
Pielstick engines are unique due to their high power-to-weight ratio and compact design, making them ideal for restricted spaces in locomotives and power plants. However, as these engines mature, sourcing quality spares becomes a challenge.
We support the two main pillars of Pielstick applications in the defense sector:
Railway & Traction (The PA Series): Support for PA4 (PA4-185, PA4-200) and PA6 engines used in diesel-electric locomotives. These engines are critical for the rail transport of heavy armor (MBTs) and supplies.
Industrial & Base Power (The PC Series): Comprehensive parts supply for PC2, PC2.5, PC2.6, and PC4medium-speed engines used in stationary power plants, ensuring energy independence for military bases and dockyards.
Engineering Insight: Many Pielstick engines share architecture between Naval and Railway applications (e.g., the PA4 VG). Our expertise allows us to cross-reference parts across these domains to find the best availability for your specific engine block.
Pielstick Engines Spare Parts Supply
We leverage a global network of licensed manufacturers and OEM surplus to supply components indexed by NATO Stock Numbers (NSN) and railway part codes:
Combustion & Power Assembly:
Cylinder Liners: Specialized nodular cast iron liners with precise honing for oil retention.
Pistons: Monobloc (steel) and Composite (steel crown/aluminum skirt) pistons for PA6 and PC series.
Connecting Rods: Serrated joint connecting rods critical for the high combustion pressures of Pielstick engines.
Fuel Injection Equipment:
Heavy fuel oil (HFO) and Diesel oil (MDO) injection pumps.
Cooled injection nozzles to prevent carbon buildup in continuous-duty industrial generators.
High-pressure fuel pipes with shielding for safety compliance.
Turbocharging & Air Systems:
Spares for BBC/ABB and Napier turbochargers commonly paired with Pielstick engines.
Charge air coolers (intercoolers) designed for high thermal loads in stationary power plants.
Exhaust expansion joints and bellows.
Governor & Control:
Woodward governor support (UG, PGA types) for precise load sharing in power plant gensets.
Managing Obsolescence in Legacy Infrastructure
The biggest threat to “Railway & Industrial” engines is the discontinuation of parts. Pielstick engines were manufactured by various licensees globally (Crossley, Fairbanks Morse, IHI, etc.), creating a complex web of part numbers.
