Measurement For Spacer Thickness
Installation Of Bevel Spring Washers(53) Bevel Spring Washers.(98) Wire.58. Once the correct size spacer has been determined, the 8T-7777 Plate and 8T-9302 Spacer can be removed. The four bevel spring washers (53) can be installed using wire (98) as a guide. 59. Assemble both of the pump rotating groups for the main hydraulic pump as follows:a. Heat bearing (81), spacer (80) and bearing (79) to a maximum temperature of 100 °C (212 °F). Install the bearings and the spacer on the shaft as shown.b. Install shims (78) making sure the distance between the top of the shim pack to the bottom of the lower bearing [dimension (X)] is 76 + 0 - 0.05 mm (2.99 + 0 -.002 in).c. Heat bearing (77) to a maximum temperature of 100 °C (212 °F). Install the bearing on the shaft as shown.d. Apply 9S-3263 Thread Lock on the threads of the shaft of the pump rotating group. Install spanner nut (76). For the correct bearing preload, turn the pump rotating group while tightening spanner nut (76). The shaft running torque must be 1 to 2 N*m (1 to 1.4 lb ft). 60. Lower the temperature of the upper and lower pump rotating groups to a temperature of -40 °C (-40 °F). Install the upper and the lower rotating pump groups in their original locations in the main pump housing. Make sure the timing marks on each of the pump rotating groups are in alignment with each other as shown. 61. Install O-ring seal (66) in the main pump housing. 62. Install lip seal (65) in cover (64). Install the seal with the lip so it will be facing toward the inside of the main pump housing and until it makes contact with the counterbore in the cover. 63. Install cover (64) in its original position in the main pump housing.64. Use Tool (C) to install retaining ring (63) to hold cover (64) in position in the pump housing. 65. Install two O-ring seals (61) on pilot pump (60). 66. Put pilot pump (60) in position in the main pump housing. Install four bolts (59) that hold the pilot pump in position.67. Turn the main pump housing over. 68. Install two rings (58) on each piston (57). 69. Install 14 pistons (57) in their original locations in the pump rotating groups. 70. Install retaining plates (55) and centering pins (56) in their original positions over pistons (57). Make sure the screw holes in the retaining plates are in alignment with the screw holes in the pump rotating groups. 71. Apply 9S-3263 Thread Lock on the threads of 14 socket head screws (54). Install the 14 socket head screws to hold retaining plates (55) to the pump rotating groups. Tighten the socket head screws evenly.
Bevel spring washers (53) are not flat. These washers should be installed so they provide the maximum amount of height.
72. Install spacer (52) and four bevel spring washers (53) in each cylinder (51). Install the bevel
