FP Diesel® Product Bulletin – March 2019

Written by Brian Cooper on February 25, 2019. Posted in FP Diesel Product Bulletin

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.

Written by qdpdev on January 28, 2019. Posted in Parts

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.
