FP Diesel® Product Bulletin – March 2019

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:
  • FP-4090028 Piston Ring Set
  • FP-4352358 Piston Ring Set
  • FP-4024767 Liner Kit

O-rings! The Important, Yet Rarely Seen Engine Part.

So many o-rings, so little time… Seriously, we have sooo many.

Have you ever tried googling o-rings? It’s a bit of a rabbit hole. While doing research for this post, we found someone who claims to have 47 million in stock (wowzers), that they have caused much tragedy, and are even a basis for an economic model. It was very weird, plentiful, and don’t even search for sizes. You might get lost. We don’t have 47 million o-rings, but we do have a great assortment for all your diesel engine needs. Our chief hooligan, mayor, and owner, Brian, is currently trying to take pictures of each of them for our new website. It’s a tall order, but he has to do it.  (No one else is willing.) Have you taken a stroll through our new site yet? If not, take a look around and give our ordering process a spin. For those that subscribe to our mailing list, there’s a 10% off coupon code available as an incentive. Visit our home page to sign-up.


We stock only the highest quality parts from the major brands and manufacturers you know and trust.


Our parts inventory is the largest in the Northwest and features a wide range of options.


Our expert team of professional hooligans has a combined total of over 50 years of hands-on experience in the diesel engine business.
