(1) Apply 9S-3263 Thread Lock on the threads of 12 bolts. (2) Apply 9S-3263 Thread Lock on the threads of 20 bolts. Torque for 20 bolts ... 900 100 N m (660 75 lb ft) (3) Apply 1U-8846 Gasket Maker to the surfaces of gear (3). (4) After you install seven pins, make stake marks near the opening of each pin hole. An example is shown in View B. (5) Apply 9S-3263 Thread Lock on the threads of ten bolts. Torque for ten bolts ... 900 100 N m (660 75 lb ft) (6) At assembly, O-rings of floating seal and all surfaces in contact with the O-rings must be clean and dry. Apply a thin coat of oil on the contacting surfaces of the metal seals before installation. (7) Torque for two plugs ... 80 10 N m (59 7 lb ft) (8) Apply 5P-3931 Anti-Seize Compound to the surfaces in contact with the pins.Use the following procedure to adjust the preload of bearing (11) :
Place a load "P" of 4000 kg (8820 lb) on bearing (11) .
Rotate the housing (12) in order to seat the bearing.
Reduce load (P) to 1000 100 kg (2200 220 lb).
Measure dimension (C) .
Measure dimension (D) of gear (9) .
Use a maximum of two shims (10) to achieve the correct clearance.
Table 1
Formula for correct clearance    
((C) - (D)) 0.05 mm (.002 inch)    Note: If two shims (10) are used, place the thinnest shim next to gear (9) . (10) Thickness of shim 110-7234 Shim ... 0.15 mm (.006 inch) 110-7235 Shim ... 0.3 mm (.012 inch) 110-7236 Shim ... 0.4 mm (.016 inch) 110-7237 Shim ... 0.5 mm (.020 inch) 110-7238 Shim ... 0.6 mm (.024 inch) 110-7239 Shim ... 0.7 mm (.028 inch) 110-7240 Shim ... 0.8 mm (.031 inch) 110-7241 Shim ... 1.0 mm (.039 inch) 110-7242 Shim ... 1.6 mm (.063 inch) (13) Use the plates to achieve the correct clearance "X". Clearance "X" equals 1.0 mm (0.04 inch) to 2.0 mm (0.08 inch). 94-0577 Plate ... 7.0 mm (.28 inch) 94-0578 Plate ... 8.0 mm (.31 inch) 94-0579 Plate ... 9.0 mm (.35 inch)
