FAQ

Q1: Is this flywheel shell a direct replacement for the original Caterpillar part?
Yes, this part is manufactured to OEM specifications and is a direct replacement for Caterpillar part numbers 3945874 and 394-5873. It is designed to bolt directly onto the C7.1 engine block without modifications. However, we recommend comparing your old part against the dimensions and bolt pattern to ensure compatibility.

Q2: What is the weight of this part, and does it include the flywheel?
This product is only the flywheel shell (housing), not the flywheel itself. The shell weighs approximately 39 kg. It serves as the protective cover and mounting point for the flywheel and starter motor. You will need to transfer your existing flywheel and ring gear to this new housing.

Q3: Can this part be used on marine or genset applications?
Yes, the Caterpillar C7.1 engine is used across multiple sectors including construction, marine, and generator sets. This flywheel shell is suitable for all those applications as long as the engine block and bell housing pattern match the C7.1 standard. For marine use, ensure your existing housing gasket is compatible with the new shell.
