Re: 700R4 build thread.

Front pump, Using the stand you made earlier out of the sunshell, Place the pump Seal down on the stand.
Remove the 5 13mm headed bolts that hold the pump halves together. Pull up on the top pump half exposing the Pump rotor, Vanes, Slide, Ring.

Remove the top Pump Ring, Lift the Pump rotor up by the torque converter lugs. Vanes will fall everywhere, Gather those up, Remove lower Pump Ring, If the plastic Rotor Pilot was left behind Remove it.
Fun Fact...The Rotor pilot's only purpose is to keep the Pump rotor centered for Torque Converter install.

Using a screwdriver or awl. Get under the primer spring & remove it.
**NOTE**Always use you hand to block springs from launching into orbit

Remove Pump Slider, Wiper seals, Slider pin & spring.

Inspect both pump halves for damage, Inspect for Pump Bushing walk.
