Q1: Why is my B3.3 engine experiencing blue smoke and high oil consumption?
A: This often points to worn piston rings or a compromised piston crown. Using the 4955416 piston during an overhaul restores the seal between the combustion chamber and the crankcase, significantly reducing oil blow-by and restoring engine power.
Q2: Can I replace just one piston in my engine?
A: While possible, it is highly recommended to replace pistons as a complete set or at least check the weight and balance against other cylinders. The 4955416 is balanced for Cummins B3.3 specifications to ensure smooth engine operation and reduced vibration.
Q3: Why Choose This Piston?
A: Because it utilizes an OEM-standard tri-metal structure. It is a product trusted by repair shops and equipment fleets globally for its ability to withstand the thermal loads of turbo-charged B3.3 configurations.
