Primary pinion input kit for P&H CN128

The 1100P407-1 primary pinion input kit serves as a mechanical assembly within the power transmission system of heavy machinery. It functions by receiving torque from the engine or a preceding transmission stage and transferring it to the subsequent gears, initiating the speed reduction and torque multiplication sequence required for machine operations. This kit typically includes the pinion gear, associated bearings, seals, and necessary fastening elements to complete the installation.

This component is compatible with the P&H CN128 Century and Terex CN128 Century crane models. The pinion gear is engineered to interface with mating gears to facilitate power transfer through the drivetrain. Proper installation of this kit ensures the alignment of the gear teeth, which is necessary for the transmission of rotational force throughout the system. The included bearings and seals support the rotational movement of the pinion while maintaining the internal environment of the transmission housing by retaining lubricant and excluding external contaminants.
