FAQ

Q: Is this oil nozzle a direct replacement for the Cummins 3687058 part?
A: Yes, this product is an exact aftermarket replacement for the Cummins OEM part number 3687058. It is designed to the same specifications, ensuring a direct fit and proper function without any modifications required.

Q: What is the function of this oil nozzle in the QSX15 engine?
A: This nozzle is used to precisely spray oil onto the piston skirt and cylinder wall. This action provides critical cooling and lubrication to the piston assembly, reducing friction and preventing seizure under high heat and load conditions. It is a vital component for engine longevity.

Q: How often should this oil nozzle be replaced during engine maintenance?
A: It is strongly recommended to replace these oil nozzles during a major engine overhaul or when the cylinder head is removed. While they are durable, they can become clogged or wear over time. Replacing them during a rebuild ensures optimal oil flow and prevents future failures. We recommend installing new nozzles with every piston and liner change.
