FAQ

Q1: Is this piston a direct fit for my Cummins NT855 engine?
This piston (Part #3095738) is designed for the standard OEM bore size for the NT855 series. It is a direct replacement for the original part. However, we always recommend verifying the piston diameter, wrist pin size, and compression height against your original piston to confirm compatibility, especially if the engine has been previously rebored or modified.

Q2: What is included in the warranty and how do I file a claim?
The piston comes with a 6-month warranty covering manufacturing defects in materials and workmanship. This does not cover damage caused by improper installation, incorrect engine tuning, or normal wear and tear. To file a claim, please contact us with your order number and a description of the issue, along with photographic evidence. We will work with you to resolve the issue promptly.

Q3: What maintenance should I perform when installing a new piston?
When installing a new piston, it is critical to also replace the piston rings, wrist pins, and connecting rod bearings. The cylinder bore must be inspected for wear, taper, and scoring. Honing or boring may be required to ensure proper ring seating. Always lubricate the piston and rings with clean engine oil during assembly and follow the manufacturer’s torque specifications for the connecting rod bolts.
