SPACER 0997174 - Caterpillar

Remove three bolts (1) and remove locking plate (2).
Illustration 2 g00992526
Reposition locking plate (2) so that hole (5) is outside of the circumference of thrust flange (3).
Install three bolts (1) removed in Step 4. Tighten three bolts (1) to a torque of 240 20 N m (175 15 lb ft).
Insert a 3/4 inch square drive through hole (5) so that the square drive contacts the outside of thrust flange (3). The square drive will prevent locking plate (2) from rotating clockwise.
Use a suitable wrench on the square drive to turn thrust flange (3) clockwise until all end play has been removed.
If necessary, turn thrust flange (3) counterclockwise to line up the holes. Insert the square drive into hole (4) to rotate thrust flange (3) counterclockwise. Rotate thrust flange (3) as far as the first correct hole alignment.
Remove the square drive and reposition locking plate (2) and bolts (1). Tighten three bolts (1) to a torque of 240 20 N m (175 15 lb ft).Reference: For more information, refer to Disassembly and Assembly, Machine Systems, "Front Frame and Rear Frame - Connect".Upper Hitch

Apply Loctite C5-A to the bearing cup bores prior to assembly.
Install cap (13) with three bolts (5) and the washers, equally spaced around the cap.
Lower the temperature of bearing cups (8) and (10) to −75° 5°C (−103° 9°F). Install cooled bearing cup (10) in the bearing housing.
Drive bearing cup (10) down to ensure contact with cap (13).
Lubricate bearing cones (11) and (9) with SAE 30 oil and install.
Install cooled bearing cup (8) and drive down to ensure light contact pressure on bearing cone (9).
Remove three bolts (5) and cap (13) installed in Step 2.
Install the following components: shim pack (7), caps (4) and (13), six bolts (5) and the washers. Tighten diagonally opposite bolts (5) to a torque of 100 20 N m (75 15 lb ft).
Install the torquing bolt assembly.
Apply a torque wrench to the torquing bolt and read the torque necessary to rotate the bearing cones.
If the torque is within a range of 2.3 to 13.6 N m (20 to 120 lb in), remove caps (4) and (13) and install lip seals (6) and (12). Lubricate the sealing lips with the lubricant being sealed.
Install caps (4) and (13) with six bolts (5) and the washers, ensuring shims (7) are in place. Apply Loctite 7649 and then apply Loctite 263 to the threads of the bolts prior to assembly. Tighten six bolts (5) to a torque of 100 20 N m (75 15 lb ft).
If the torque is LESS THAN 2.3 N m (20 lb in) or GREATER THAN 13.6 N m (120 lb in), remove or add shims to obtain the correct rotating torque. The removal of shims will increase the torque and the addition of shims
