The Oil circuit conduit is a precisely routed pipe that delivers transmission fluid to the main shaft bearings and gears, ensuring adequate lubrication and cooling. Its correct placement within The part prevents dry starts and reduces friction.

This baffle ring is a spring-steel retaining ring that fits into a groove on the main shaft, preventing axial movement of gears and bearings. It is a critical locking element in The part, ensuring correct component positioning.

The Needle roller bearing outer ring provides a hardened raceway for the needle rollers that support the main shaft. It is designed to withstand high radial loads and is an essential part of The part for smooth shaft rotation.

This snap ring secures the needle roller bearing outer ring within the transmission housing. Its elastic design allows for easy installation and provides a positive lock, preventing axial movement in the main shaft assembly.

The Spline sleeve is a toothed coupling that connects the main shaft to the output yoke or other driveline components. Its precision-ground splines ensure a secure, backlash-free connection, critical for the integrity of the main shaft assembly.

The Quill bearing (K909835) is a precision needle roller bearing that supports the main shaft at its forward end, ensuring accurate alignment and reducing wear. Its compact design is ideal for the confined space of the main shaft assembly.

This sliding sleeve is used to engage the reverse gear, moving axially on the main shaft to couple the reverse idler gear. Its robust construction and precise splines ensure smooth and reliable reverse gear selection in the main shaft assembly.

The Main shaft gear spacer is a hardened steel ring that maintains correct axial spacing between gears on the main shaft. It ensures that each gear is precisely positioned for proper mesh with the countershaft gears in the main shaft assembly.

The Reverse gear of main shaft is a helical-cut gear that engages with the reverse idler gear to provide backward motion. Its precise tooth profile ensures quiet and efficient reverse operation within the main shaft assembly.

The First-speed gear is the largest gear on the main shaft, providing the highest torque multiplication for starting and climbing. Its hardened teeth and precise finish ensure durability in the main shaft assembly.

This sliding sleeve is used in AMT transmissions to synchronize and engage different gear ratios. Its hardened splines and precise internal geometry ensure smooth, rapid gear changes in the main shaft assembly.

The Second-speed gear provides intermediate gearing for moderate loads and speeds. Its helical teeth reduce noise and vibration, contributing to the overall refinement of the main shaft assembly.

The Third-speed gear is designed for efficient cruising at moderate speeds. Its precision-ground teeth ensure smooth engagement and quiet operation, making it a reliable component of the main shaft assembly.

The Fourth-speed gear provides direct or near-direct drive for efficient high-speed travel. Its robust construction and precise tooth profile contribute to the overall performance of the main shaft assembly.

The Fifth-speed gear is an overdrive gear that allows the output shaft to turn faster than the input shaft, improving fuel economy at highway speeds. Its helical design ensures quiet and efficient operation in the main shaft assembly.

The Main shaft is the central rotating member of the transmission output section, carrying all the gears and bearings. It is precision-machined from high-strength steel and heat-treated for maximum durability, forming the backbone of the main shaft assembly.

The Main shaft hex key is a specially shaped tool or component used to drive or lock the main shaft during assembly. It ensures correct torque application and proper engagement of the main shaft assembly components.

The Elastic cylindrical pin is a spring-steel pin used to secure components such as gears or sleeves to the main shaft. Its split design provides a secure interference fit, preventing loosening in the main shaft assembly.
