FAQ

Q1: Can I use this piston in a Cummins 6CTA 8.3L engine from a 1999 model year?
This piston (3919564) is designed for the 6CT/6CTA/6CT8.3 engine family. While it is the correct standard size (114mm) and combustion bowl (63.8mm) for many production years of these engines, we recommend removing your old piston and comparing the bowl depth, pin height, and overall geometry. We cannot guarantee fitment for specific model years without direct verification, but it is a common replacement for these platforms.

Q2: What is the correct installation procedure for this piston?
Ensure the cylinder bore is clean and within service limits for the 114mm standard size. Lubricate the piston pin and install it into the connecting rod. Use a ring compressor to install the piston assembly into the cylinder. Always follow the engine manufacturer’s torque specifications for connecting rod bolts. We recommend replacing piston rings and cylinder liners simultaneously for optimal performance.

Q3: How do I verify if this is the correct part before ordering?
Verify the OEM part number stamped on your existing piston. Look for numbers like 3919564, 3923163, 3919928, or 3802397. Additionally, measure your piston’s bore diameter (should be 114mm) and the wrist pin diameter (should be 45mm). If your engine has been rebuilt with oversized pistons, this standard size part will not be suitable.
