Everything that we need

It might not be how everybody does it, but this way worked well to pull the 3-4 hub and slider assembly off of the mainshaft. The bearing separator did the trick and came in handy for several other steps while reassembling the mainshaft.

Once the mainshaft was disassembled, all the old hubs and sliders were discarded and the center bearing was driven out of the midplate.

First, second and third gears and the midplate were soaked in diesel fuel to clean them.

The midplate was media- and then glass bead-blasted before it was fitted with a new bearing and snap ring. 

It took a long time and a lot of money to assemble all the preferred parts to put this back together, but the super nice parts fit up well and the original gears turn freely with no excessive play on the cleaned mainshaft.

By the end of the day, the gear train was assembled onto the mainshaft with new bearing, hubs, sliders, snap rings and synchronizers.

This is ready to install back into the housing.
