The cluster gear is supported by which of the following?

The cluster gear is supported by both needle bearings and roller bearings in a manual transmission setup. This dual support system is essential for the proper functioning and longevity of the transmission.

Needle bearings are utilized around the countershaft to allow for smooth rotation of the cluster gear, minimizing friction and wear. These needle bearings provide a high load-carrying capacity in a compact design, which is important in a confined space such as a manual transmission.

Additionally, roller bearings are positioned between the countershaft and the transmission case, specifically designed to support the load of the cluster gear while maintaining alignment with the transmission's internal components. These roller bearings also reduce friction and help with the efficient transfer of power through the transmission.

By supporting the cluster gear with both needle and roller bearings, the manual transmission can achieve optimal performance, durability, and the capacity to handle the stresses involved in gear shifting and power distribution. This combined use of bearings ensures that the cluster gear operates smoothly and effectively, contributing to the overall reliability of the vehicle's transmission system.
