New Stronger Hub For Torque Converter Impeller Is Made Of Nodular Iron {3101}
Usage:
992C Loaders
Description of Change: A new hub is used for the torque converter impeller in 992C Loaders. The new hub is made of nodular iron, which is stronger than the gray iron used in the former hub. This lowers the stress on hub mounting bolts, and will prevent possible broken bolts.
Adaptable As: Direct replacement. The new 9G1904 Hub can be installed in place of the former 8P6837 Hub, which is canceled.
