GEAR-RING 1026457 - Caterpillar

Table 3
    "C ="     B × (T + SDT)        
B + A    "C" is the torque wrench reading in newton meters (N m)."B" is the length of the torque wrench in meters."A" is the bolt circle radius of axle housing assembly (2) in meters which is equal to 0.269 m (10.5905 inch)."SDT" is the actual seal drag torque in newton meters (N m)."T" is the axle bearing preload rolling torque. The preload rolling torque for bearing cones (19) and (23) is 7 to 13 N m (62 to 115 lb in).
The axle shaft should have zero end play. If the axle bearing preload rolling torque exceeds the specification, back off bearing nut (18) by 1/8 turn and reseat bearing cone (19) against bearing nut (18). Perform Step 12 again.
The following steps are for the assembly of planetary carrier assembly (10) :
Illustration 6 g03372147
Install retaining ring (8) into planet carrier (17) .
Illustration 7 g03371986
Illustration 8 g03371981
Apply a thin coat of clean SAE 30 oil on all parts of planetary carrier assembly (10) .
Install bearing (15) in planetary gear (14) .
Install thrust washer (13), thrust washer (16), and planetary gear (14) in planetary carrier assembly (10) .
Install planetary shaft (12) in the carrier. Make sure that the spring pin hole in the shaft is aligned with the spring pin assembly hole in the carrier. Install a new spring pin assembly (11) through the carrier and in planetary shaft (12). Install spring pin (11) slightly below the outside surface of the carrier.

Install retaining ring (8) onto axle shaft (9) .
Illustration 11 g03371963
Install pin (4), spring pin (5), O-ring seal (6), and plug (7). Tighten plug (7) to a torque of 60 6 N m (44 4 lb ft).

Illustration 13 g03371745
Attach Tooling (B) (not shown) and a suitable lifting device to axle housing assembly (2). The weight of axle housing assembly (2) is approximately 365 kg (800 lb). Use Tooling (B) and the suitable lifting device in order to remove axle housing assembly (2) from Tooling (A). Install the other half of axle housing (1) on Tooling (A) in a vertical position.
Apply Tooling (H) on the mating surfaces of axle housing assembly (2) and of axle housing (1) .
Illustration 14 g03371798
Use Tooling (B) and the suitable lifting device in order to position axle housing assembly (2) onto the axle housing, as shown.
Install bolts (3) that secure axle housing assembly (2) to the axle housing. Tighten bolts (3) to a torque of 300 40 N m (220 30 lb ft).End By:
Install the rear trunnion support if the rear oscillating axle was removed.
Install the front trunnion if the rear oscillating axle was removed.
Install the rear oscillating axle.
Install the front fixed axle.
