TUBE AS 8V6871 - Caterpillar

The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put clean SAE 30 oil on the contact surfaces of the metal seals.69. Install a Duo-Cone seal (34) in the motor casing with tool (J).70. Readjust swash plate adjustment screw (61) to its original position, and lock it in place. 71. Install two bearings (33) and the shims in travel drive housing (35).72. Put travel drive housing (35) in its original position on ring gear (32). Install the twenty socket head bolts which hold it. Tighten the bolts to a torque of 540 54 N m (400 40 lb ft).

The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put clean SAE 30 oil on the contact surfaces of the metal seals.73. Install the other portion of Duo-Cone seal (34) in travel drive housing (35) with tool (J). 74. Fasten tool (B) and a hoist to ring gear assembly (32) as shown. Put the ring gear assembly in position on the motor casing. Be sure bearings (33) are seated properly. 75. Using a depth micrometer, measure the step height [dimension (V)] of bearing retainer (31) at several locations around the retainer. Find the average dimension measured, and record it. 76. Using a depth micrometer, measure the distance from the top face of the motor casing and the inner race of bearing (33) [dimension (W)] at several locations around the motor casing. Find the average of the dimensions measured, and record it.77. Determine the correct thickness of the shim to be used between the top face of the motor casing and bearing retainer (31). The thickness of the shim is equal to (V - W) - [0.05 to 0.1 mm (0.002 to 0.004 in). Select the correct thickness shim. 78. Install the correct thickness shim and bearing retainer (31). Install the twelve bolts that hold the bearing retainer in place. Tighten the bolts to a torque of 120 12 N m (85 8 lb ft).79. Assemble the third stage carrier as follows: a. Lower the temperature of needle bearing (30), and install it in gear (29). b. Put a side plate (28) on each side of gear (29). Install the side plates and the gear in third stage carrier.c. Install planetary shaft (26) in the carrier and through the gear. Be sure the spring pin hole in the planetary shaft is in alignment with the spring pin hole in the carrier. Install a new spring pin (27) in the carrier and into the planetary shaft. Install the spring pin until it is slightly below the outside surface of the carrier. d. To prevent the spring pin from falling out, make a stake mark on each side of the spring pin hole in the carrier. Each stake mark should be approximately
