...but you will need a hydraulic press to do the front seal if IT is
leaking.

Other requirements are a 3/4" drag link socket with 1mm ground off each
side (Sears or Snap-On have these, but probably a special order at most Sears)
and a hand impact wrench to loosen the X-caps.

Torque spec for the X-Caps is 37 ft-lb.  You can achieve this with a
torque wrench IF the pump is held securely in a vice.
