Here at Quality Diesel parts we stand by our name and offer customers the best parts in the business – Federal-Mogul Motorparts. They are the oldest and most comprehensive parts manufacturer in the world. Each month the company, also known as FP Diesel®, highlights new products from a variety of their lines. This month they are announcing new Cummins® Pistons and Cylinder Components for Cummins QSK19, QSK38 and QSK50 ferrous cast ductile (FCD) iron piston applications.
According to the company, FP Diesel’s FCD pistons are stronger than previous designs. The FCD material has improved dimensional stability, a critical feature in these high-horsepower engines.
Their QSK pistons have a manganese phosphate coating for greater resistance against the corrosive effects of higher sulfate diesel fuels.
Other benefits include:
Improved lubrication and film retention
Reduced pin scuffing and better low-friction motion
Prevents galling and provides improved wear resistance
FP Diesel® QSK piston kits include piston pin and retainers. The new piston pin FP-4910289 is the upgraded design with a straight inner diameter. The new design is stronger and can better withstand cylinder pressures found in QSK HHP engines.
When servicing these engines, they do not recommend mixing piston kits with new style and old style piston pins.
Additional QSK cylinder components include:
