SWITCH-LIQUID LEVEL 3104577 - Caterpillar

Refer to the topic "Assembly And Installation Of Conventional Duo-Cone Seals" in this module.
The rubber seals and all of the surfaces that make contact with the seals must be clean and dry. After the installation of the seals, put clean SAE 30 weight oil on the contact surfaces of the metal seals. 45. Using Tool (D), install Duo-Cone seal (57) in the main housing. 46. Install bearing (56) on the main housing. 47. Install race (55) to the ring gear. Using Tool (D), install Duo-Cone seal (54) to the ring gear. 48. Reposition the ring gear and install race (53). 49. Install bearing (52) in the ring gear.
Do not scratch or damage the Duo-Cone seals in the main housing or the ring gear during assembly of these two components. After the installation of the ring gear on the main housing, there will be a small gap between the components. The gap is caused by the Duo-Cone seals and will be eliminated during installation of ring nut (51).
50. Fasten Tooling (C) and a hoist to ring gear (37) as shown. Install the ring gear on the main housing. 51. Use the following procedure to make a preload adjustment of bearing (52) as follows: a. Tighten nut (51) until there is no gap between the main housing and bearing (52).b. Rotate ring gear (37) several turns.c. Turn nut (51) in and/or out until rotational torque of ring gear (37) is 21 5 N m (15 4 lb ft).52. Install four screws (50). Tighten the screws to a torque of 40 5 N m (29 4 lb ft). 53. Put washer (49) on the carrier assembly shaft. Install bearing (47) and bushing (48) to planetary gear (46). Install gear (46) on the carrier assembly shaft. 54. Install retaining ring (46) on sun gear (45).55. Install thrust plate (44) and four screws (43). Tighten the screws to a torque of 44 5 N m (32 4 lb ft). 56. Install bearing (42) and planetary gear (41) on the carrier shaft assembly.57. Install the other two planetary gears on the carrier assembly as in Step 56.58. Install planetary carrier (40) in the final drive housing. 59. Install sun gear (39). 60. Install thrust plate (38) on the carrier assembly. Use an appropriate thrustr plate to get a clearance of 0.30 to 1.20 mm (.011 to .047 in) between the thrust plate and planetary carrier (40). Refer to the "Specifications module, 311B, 312B and 312 B L Excavators, Hydraulic Systems" for plate part numbers and thicknesses. 61. Make sure the machined surface of ring gear (37) and cover (36) is thoroughly clean, free of dirt and debris and is dry. Put a bead of 1U-8846 Gasket Maker around the machined surface of the ring gear. Put cover (36) in its original position on the ring gear.62. Install bolts (35) and the washers that hold the cover. Tighten the sixteen bolts to a torque of 39 2 N
