Tech Tip – Frozen Treat TD, TF Gearbox

From Moss Motoring 1985

In building TD and TF Gearboxes, a dummy shaft is used in removing and replacing the cluster gear which is located in the bottom of the gear box.

One of the last steps in the assembly process is to turn the gearbox over allowing the cluster gear to fall into place. The dummy shaft is then tapped out using the longer permanent shaft.

In each end of the cluster gear are 16 needle bearings. It is most frustrating for a needle bearing to fall out as the dummy shaft is removed. This necessitates the disassembly of the gearbox to that point.

A simple remedy is to assemble on the dummy shaft the cluster gear, needle bearings, and washers. Pack in heavy grease and place the assembly in the freezer the night before assembly. The result all parts held firmly in place!
