(1) Thickness of four new friction discs and three new clutch plates ... 28.50 0.95 mm (1.115 0.037 inch) Thickness of new 6Y-9373 Disc ... 4.70 0.18 mm (0.185 0.007 inch) Thickness of new 7T-6994 Plate ... 3.175 0.075 mm (0.1250 0.0030 inch) (5) Apply 5P-3413 Sealant before you install the four plugs. (6) Use the required shims in order to provide the following backlash in the bevel gears. ... 0.210 0.075 mm (0.0083 0.0030 inch)Note: Measure the backlash on three equally spaced teeth. (7) Inside diameter of new planetary gear ... 51.948 0.010 mm (2.0452 0.0004 inch) (8) Diameter of new planetary shaft ... 42.395 0.006 mm (1.6691 0.0002 inch) (9) Inside diameter of new planetary gear ... 58.298 0.010 mm (2.2952 0.0004 inch) (10) Diameter of new planetary shaft ... 42.395 0.008 mm (1.6691 0.0003 inch) (12) Thickness of four new friction discs and three new brake plates ... 28.50 0.95 mm (1.115 0.037 inch) Thickness of new 6Y-9373 Disc ... 4.70 0.18 mm (0.185 0.007 inch) Thickness of new 7T-6994 Plate ... 3.175 0.075 mm (0.1250 0.0030 inch) (13) Apply 5P-3413 Sealant to the flanges which contact the carriers. (14) Inside diameter of new planetary gear ... 51.948 0.010 mm (2.0452 0.0004 inch) (15) Diameter of new planetary shaft ... 42.395 0.008 mm (1.6691 0.0003 inch) (16) Torque for three bolts ... 50 10 N m (37 7 lb ft)Procedure for the Preload Torque of the Pinion Bearings
Gradually tighten nut (11). Then, check the torque. Measure the torque by rotation of the pinion within the bearings. The correct preload torque is 0.3 to 1.35 N m (2.66 to 12.0 lb in).
Bend the tab on the lockwasher into the slot on the nut.Procedure for the Preload Torque of the Carrier Bearings
Gradually tighten three equally spaced bolts (2). Then, check the torque. Measure the torque by rotation of the planetary carrier within the bearings. The correct preload torque is 2.25 to 4.0 N m (20 to 35 lb in).
Measure the gap between plate (3) and carrier housing (17). Select a shim pack (4) of equal thickness to the measurement.
Remove bolts (2) and install shim pack (4) .
Install bolts (2) and tighten the bolts.
Measure the torque and adjust the torque again in Step 1.
