53. Press flange plate (56) in its original position in the travel drive housing. Keep the flange plate level and true during installation.
If bolts (55) are not tightened evenly, a small amount at a time, flange plate (56) will tilt resulting in seizure of the bolts. Also, the seating face of each bolt must be in face-to-face contact with the flange plate after they are tightened to the specified torque value.
54. Be sure bolts (55) are thoroughly clean and dry. Put 5P-3931 Anti-Seize Compound on the shank of each bolt and 9S-3263 Thread Lock on the threads of each bolt. Install the bolts, and tighten evenly, a small amount at a time, until the seating face of each bolt is in contact with the flange plate. Remove Tool (D). Tighten the bolts to a final torque value of 368 59 N m (270 44 lb ft). Retaining ring (54) is available in several thicknesses. See the Parts Manual. The thickness of retaining ring (54) determines the amount of preload on the bearings on each shaft in gear assembly (61). The preload on the bearings should be 0 to 0.05 mm (0 to 0.002 in) tight.55. Install retaining rings (54) in their original locations. 56. Install pin (52) in the spindle.57. Install oil seal (53) in the spindle. Install the seal until it makes contact with the counterbore in the spindle and with the sealing lip facing toward the travel drive housing. Put clean hydraulic oil on the lip of the oil seal. 58. Install bearing (51) on shaft (50) with a press. Install the bearing until it makes contact with the shoulder on the shaft. 59. Install shaft (50) in the spindle. Be sure the bearing is seated against the counterbore in the spindle. Install swash plate (49) over the shaft. Be sure the swash plate engages with pin (52) in the spindle. Also, be sure the swash plate is flat against the counterbore in the spindle. 60. Assemble barrel assembly (40) as follows: a. Install washer (48), spring (47) and washer (46) in barrel (40). Install the cylinder block in a press. Compress spring (47) until snap ring (45) can be installed. Install retaining ring (45). b. Install the three rollers in barrel (40). Install washer (44). Install the washer with the chamfered inside diameter toward the barrel. Install guide (43) on barrel (40). c. Put clean hydraulic oil on nine piston assemblies (41). Install the piston assemblies in their original bore in retainer plate (42). Install the retainer plate with the piston assemblies in their original bores in barrel (40).
Do not let the barrel assembly fall apart when it is installed over shaft (50) and in the spindle.
61. Turn the spindle and travel drive housing on its side. Install barrel assembly (40) over shaft (50) and in the spindle.62. Put clean hydraulic oil on two friction plates and two separator plates (39). Install the plates in alternating order in the spindle. Start with
