BORGWARNER BV55 Turbocharger - Dieselmax 4.8L
Original BorgWarner turbocharger from the BV55 series, designed specifically for JCB 4.8-liter diesel power units. This component is dedicated to the 444 and 448 (Dieselmax / Ecomax) engine families, providing them with peak performance, precise boost control, and full compatibility with JCB machine control systems.
Key Product Advantages:
- Optimization for 4.8L Engines: The turbine's operational characteristics are strictly matched to the injection maps and exhaust flow of 444 and 448 engines, guaranteeing low fuel consumption while maintaining high torque.
- BorgWarner Durability: The use of advanced metal alloys in the rotor and housing ensures resistance to extreme exhaust temperatures typical of heavy-duty construction work.
- Precise Regulation: The boost control system allows for lightning-fast engine response to load, which is critical in backhoe loaders and telescopic handlers.

Expert Advice: 4.8L engines are characterized by high oil flow for turbo lubrication. When installing a new BV55 unit, it is crucial to check the oil pickup screen for debris and replace the oil filter with an original JCB filter. This ensures proper lubrication pressure for the turbine’s journal bearings from the very first second after start-up.
