This is the sealing rings and thrust washer for the rear drum. The thrust washer is the same one as is on the stator support and they are avaliable in select thicknesses for end play setting if needed. The sealing rings should fit in the groves with very little side play. They should also fit tightly in the bore they ride in. The two smaller ones have two sizes, the newer 46RE input shafts are just a little bit bigger in diameter. The bore that a shaft fits into should be smooth and free of nicks.

A small amount of assembly lube and the piston will slide into the drum with a slight rocking motion. This shows the drum setting on the stator support clamped in a vise. It also shows the stock location of the return springs before the retainer is installed. This drum has the intermediate band wrapped around it. Sometimes it is very glazed, with it on the stator support I can use a scotch bright pad on a die grinder to remove the glaze. Just touch the spinning pad to the drum and it will spin, and move the die grinder up and down to create a uniform pattern.

After the front and rear drums are assembled including the thrust washer and input shaft sealing rings the two can be assembled together like this. They can be set aside until later.

This is a close up of the last picture wit an extra clutch and steel stacked on the standard pressure plate to show thickness.

Next I build the pump, this is the driver I use to install the new pump bushing. Lots of times I choose not to replace some of the bushings in a given transmission but I never rebuild one without replacing the pump bushing.
