Figure 56. Install the splined seal in the end of the inner shaft of the input drum.Dunk the torrington bearing that goes over the end of the inner shaft, and place it in the input drum. Place the input drum over the front planetary in the transmission, Make sure it is all the way down.
In the next step, we will be installing the reverse input drum and checking end play of the input shaft. There are shims and a torrington bearing on top of the input drum that set the end play once the pump is installed.
Figure 57. Install the reverse input drum on the input drum and make sure the teeth of the sun shell are engaged with it. Make sure it is all the way down. It may be easier to put the input drum and reverse drum in as an assembly. Now is the time to check the input shaft end play.
A pump rebuild will not be detailed in this build, a complete assembled performance pump was purchased so it would not be necessary. Set the pump gasket in the case, then make sure the outer pump o-ring is not on, and set the pump in the case and snug down a couple of the bolts. Now you can take a dial indicator and check how much the shaft moves back and forth.
