19. Remove tooling (D). Remove the covers and the shims from each side of the body. Keep the shims with their respective covers. Remove the swashplate from the body. Put the pistons (18) in position on the plate in the swashplate in their correct order. Install retraction plate (21) over the pistons. Put the original amount of shims and the retraction bearings in position on the swashplate. Install the locks and bolts (19).20. Measure the clearance between the piston slippers and plate (1) with a feeler gauge. The clearance must be .003 .001 in. (0.08 0.03 mm). Add or remove shims if the clearance is not correct. Bend locks (20) against bolts (19). 21. Put spacer (25), spring (23) and spacer (24) in position in barrel (22). 22. Put barrel (22) in position on a press. Put tooling (A) in position on the face of the barrel.23. Put spring (23) in compression with the press. Install the snap ring (26) with tooling (B). Remove the barrel from the press. The guard for the press has been removed for photo illustration. 24. Put the barrel and tooling (A) in position on tool (C) as shown.25. Put the pistons in their correct locations in the barrel. 26. Heat bearing cone (28) to a maximum temperature of 275°F (135°C). Install bearing cone (28) on shaft (27).27. Put the shaft and the bearing cone in position in the swashplate and the barrel. 28. Put pump body (29) in position over the swashplate, barrel and the shaft.29. Tilt the pump on tool (C). Keep the tool against the barrel face and lower the pump into position on tool (E). Install the bolts and the nuts that hold the pump to tool (E).30. Remove tool (C). Push the swashplate, barrel and the shaft into the pump body. 31. Put correct amount of shims (31) in position on the covers. Install O-ring seals (30) on the covers. Put a small amount of clean oil on the seals. Put the covers in position in the body. Install the bolts that hold the covers.32. Install tooling (F) on the pump body and against tool (A) as shown.
Tool (A) must be used to prevent damage to the face of the barrel.
33. Tighten the nuts on tooling (F) to put the spring in the barrel in compression. Install spiral snap ring (32) on the shaft. Slowly loosen the nuts to release the compression on the spring. Remove tooling (F).34. Heat bearing cone (33) to a maximum temperature of 275°F (135°C). 35. Install bearing cone (33) on the shaft. 36. Lower the temperature of bearing cup (34). Install bearing cup (34) in the head.37. Install seven teflon rings (35) and seven rubber seals (36) in head (37). Install the teflon rings in the outer grooves toward the outside surfaces of the head. Install the teflon rings in the inner grooves toward the center of the head. This will make sure the rubber seals are toward the pressure holes
