FAQ

Q1: How can I confirm this top gasket kit (3801330) fits my specific NT855 engine?
A1: The NT855 engine has been produced in various configurations over the years. To ensure a perfect fit, we recommend comparing the gasket shapes and bolt holes in this kit with your old gasket set. You can also cross-reference your engine’s CPL (Control Parts List) number with the kit’s application. If you have your engine serial number, please contact our support team for verification assistance.

Q2: What is the typical installation procedure for this top gasket kit?
A2: Installation should only be performed by a qualified diesel mechanic. The process generally involves removing the cylinder head, cleaning the mating surfaces thoroughly, and replacing all gaskets in the kit according to the engine’s torque specifications and sequence. We recommend using a new set of head bolts and following the strict tightening procedure outlined in the Cummins NT855 service manual to prevent gasket failure.

Q3: Does this kit include the head gasket and valve stem seals?
A3: Yes, as a “Top Gasket Kit,” it is designed to include all the critical gaskets and seals needed for a cylinder head overhaul. This typically includes the cylinder head gasket, valve cover gasket, intake/exhaust manifold gaskets, and valve stem seals. Please refer to the kit’s packing list upon receipt to confirm the exact contents. For a complete engine overhaul, a separate lower gasket set will be required.
