1.     Remove hydraulic feed line, (ref# 60) from hydraulic intake valve, (ref# 59) and also remove hydraulic
   return line, (ref# 69) from  the pressure control valve, (ref# 70). Plug lines to minimize oil loss. (Hint;
   golf tees work well for this)
2.     Remove the bolts, (ref# 57) passing through the side frames, (ref# 106, 107), into the crossblock,
   (ref# 56).
3.     Place a drain tray under cylinder area.
4.     Grasp the pump assembly, and pull away from the piston. Stop when piston pulls free, to allow the
   hydraulic oil to drain into pan. Completely remove pump assembly from between side frames.
5.     If only replacing piston seals, (ref# 87) continue at step 15.
6.     Remove the piston, (ref# 86) from eccentric bearing, (ref# 95). Move to clean work bench for repairs.

   NOTE: Use extreme caution not to damage circlip or the internal circlip groove of piston.
   NOTE: Piston rod circlip, washer, o-ring, and nut are not available individually. Parts are available
   with the purchase of piston rod, (ref# 90) only.
   NOTE:  The circlip will have one sharp edge and one smooth edge. The smooth edge should be
   towards the washer. If reversed, the rod will continually pull out of the piston.
8.     Remove bronze piston rod seat, (ref# 89) from piston, (ref# 88).
9.     Examine all parts for wear or damage. Replace as required.
