1. Remove hydraulic feed line, (ref# 63) from hydraulic intake valve, (ref# 62) and also remove hydraulic

return line, (ref# 72) from the pressure control valve, (ref# 73). Plug lines to minimize oil loss. (Hint; golf
tees work well for this)

2. Remove the bolts, (ref# 114) passing through the side frames, (ref# 110,111), into the crossblock, (ref#

60).

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# 90) continue at step 15.
6. Remove the piston, (ref# 89) from eccentric bearing, (ref# 98). Move to clean work bench for repairs.
