Illustration 45 g01352299
Install lip seal (16) into housing (13).
Illustration 46 g01355702
Turn over housing (13). Install wear sleeves (15). The diagonal cuts that are in wear sleeves (15) are separated by 90°. Apply Tooling (S) onto thrust washer (14). Install thrust washer (14).
Illustration 47 g02033793
Use Tooling (A) and a suitable lifting device to install housing (13). The weight of housing (13) is approximately 54 kg (120 lb). Install shims (12). Use a suitable soft hammer to drive the wear sleeves into housing (13) until the sleeves are flush with the top of the bore surface. Do not install the shims at this time.
Illustration 48 g02033646
Drill three equally spaced 8 mm (5/16 inch) holes in retainer (11). The holes must be centered on the existing bolt hole pattern and perpendicular to each surface.
Measure the thickness of retainer (11) at the three hole locations. Average the three measurements and record the result as Dimension (A).
Illustration 49 g02033655
Install retainer (11). Install three of bolts (10). Tighten bolts (10) to a torque of 50 7 N m (37 5 lb ft). Completely loosen bolts (10). Finger tighten bolts (10). Use Tooling (T) to measure the gap between the top surface of retainer (11) and the final drive housing at the three 8 mm (5/16 inch) hole locations. Record the measurement from each of the three locations as the nominal gap or Dimension (B).
Calculate the shim pack thickness for the three measurement locations by subtracting Dimension (A) from the Dimension (B) giving you Dimension (C). Remove bolts (10) and retainer (11).
Illustration 50 g02033934
Install a number of shims (12) that is equal to Dimension (C) plus + 0.075 - 0.025 mm (+ 0.0030 - 0.0010 inch). Install retainer (11). Install bolts (10). Tighten bolts (10) to a torque of 270 40 N m (199 30 lb ft).
Illustration 51 g01414071
Apply Tooling (L) to the mating surface of final drive housing (8). Use Tooling (A), Tooling (C), and two suitable lifting devices to install final drive housing (8). The weight of final drive housing (8) is approximately 191 kg (420 lb). Install bolts (9A). Tighten bolts (9A) to a torque of 105 20 N m (77 15 lb ft). Install nuts (9). Tighten nuts (9) to a torque of 530 70 N m (391 52 lb ft).
Illustration 52 g01414357
Install bearing cone (7).
Illustration 53 g01622865
Drill three 6.40 mm (0.252 inch) equally spaced holes (Y) on a circle with a diameter of 55.00 mm (2.16 inch) on retainer (4).

Illustration 55 g01414028
typical example
Install sprocket (2) and sprocket (6) onto rear axle (1). Note: Assemble sprocket (2) and sprocket (6) so that the teeth on the sprockets are aligned with each other.
Install retainer (4) and Tooling (P). Tighten Tooling (P) to a torque of 48 3 N m (35 2 lb ft) while you are turning the sprocket. Ensure that the torque has equalized. Turn the sprocket three times. Use Tooling (M) to measure the distance from the face of the spindle shaft to surface (X) in three places and
