Replacing a worn or chipped gear with this new component restores the transmission’s efficiency and reduces noise, ensuring the input shaft and gear system performs as intended.

The Flattened round wire snap ring for hole is a precision retaining ring designed to secure the cylindrical roller bearing within the transmission housing. Its flattened round wire profile provides a larger contact area, distributing the load evenly and preventing the bearing from shifting axially. This snap ring is an essential component for maintaining the correct bearing position in the input shaft and gear assembly.

Manufactured from high-carbon spring steel with a corrosion-resistant coating, the Flattened round wire snap ring for hole offers excellent fatigue strength and retention force. Its design allows for easy installation and removal using standard snap-ring pliers, simplifying maintenance. This snap ring is a critical part of the input shaft and gear kit, ensuring that the bearing remains correctly positioned under all operating conditions.

Using the correct Flattened round wire snap ring for hole is essential for the reliability of the input shaft and gear assembly. A worn or incorrect snap ring can allow the bearing to move, causing misalignment and premature failure. This genuine replacement ensures the proper retention and long service life of the bearing.

The Spacer bushing is a precision-machined cylindrical sleeve used to maintain the correct axial spacing between the input shaft gear and the bearing. It ensures that the gear and bearing are properly positioned within the housing, preventing end play and reducing wear. This bushing is a critical component for achieving the correct preload and alignment in the input shaft and gear assembly.

Manufactured from high-quality steel with a hardened and ground surface, the Spacer bushing offers excellent wear resistance and dimensional stability. Its precise length and inner/outer diameters ensure a perfect fit between the gear and bearing, maintaining the correct gear mesh and bearing load. This bushing is an essential part of the input shaft and gear kit, ensuring the longevity and smooth operation of the transmission.

Replacing a worn or damaged Spacer bushing with this genuine component restores the correct axial positioning, preventing excessive gear wear and bearing failure. Its use is mandatory for any rebuild of the input shaft and gear assembly.

The Cylindrical roller bearing NUP213ENC3 is a high-capacity bearing designed to support the input shaft under heavy radial and moderate axial loads. This bearing features a snap ring groove on its outer ring, allowing it to be secured axially within the housing using the corresponding snap ring. Its cylindrical roller design provides high load-carrying capacity and low friction, making it ideal for the demanding environment of a heavy-duty transmission.

Manufactured from high-quality bearing steel with precision-ground rollers and raceways, the Cylindrical roller bearing NUP213ENC3 offers exceptional durability and smooth rotation. Its C3 internal clearance allows for thermal expansion, ensuring reliable operation even at elevated temperatures. This bearing is a critical component of the input shaft and gear assembly, providing the support needed for long-term, trouble-free operation.

The Cylindrical roller bearing NUP213ENC3 is supplied as a genuine replacement, guaranteeing the correct dimensions and quality. Replacing a worn or damaged bearing with this new unit ensures smooth rotation and prevents shaft runout, extending the life of the entire input shaft and gear system.

The Optional part set of circlip is a selection of snap rings in various thicknesses, allowing the technician to fine-tune the axial positioning of the bearing and gear assembly. This set provides the flexibility needed to achieve the correct end play and preload, compensating for manufacturing tolerances and wear. It is an essential accessory for any precise rebuild of the input shaft and gear system.

Each circlip in the Optional part set of circlip is manufactured from high-quality spring steel with a consistent thickness tolerance, ensuring accurate positioning.
