Remove the 2 flanges, 8 discs and 7 plates. note Check the number of disc. (Refer to RR PLANETARY GEAR ASSEMBLY INSPECTION-INSPECT BRAKE DISK SET No. 4 (B4) )

Remove the RR planetary gear assembly with the thrust bearing race No. 9, thrust needle roller with race bearing and thrust needle roller bearing.

1.Set the special tools as shown in the illustration, and compress the spring. Spring compressor body (MD998903) Retainer (MD998924) 2. caution Be careful not to expand the shaft snap ring too much. Using special tools, remove the shaft snap ring.

3.Remove the low/reverse brake return spring sub-assembly.

1.While pushing the inner brake piston No. 4 by hand, apply compressed air (392 kPa) into the oil passage as shown in the illustration and remove the inner brake piston No. 4 from the transmission case. note When applying compressed air, shut a oil passage of the transmission case as shown in the illustration.

2.Remove the inner brake piston No. 4, brake reaction sleeve and reverse brake piston.

3.Remove the 2 O-rings from the inner brake piston No. 4. SIZE: O-ring Inner diameter (mm) Thickness (mm) 67.35 2.62 116.40 2.62

4.Remove the 2 O-rings from the brake reaction sleeve. SIZE: O-ring Inner diameter (mm) Thickness (mm) 79.10 2.62 128.00 2.62

5.Remove the O-ring from the low/reverse brake piston. SIZE: O-ring Inner diameter (mm) Thickness (mm) 131.60 2.62

REASSEMBLY

1. caution Be careful not to damage the O-ring and the low/reverse brake piston. Coat the new O-ring with ATF, and install it to the low/reverse brake piston. SIZE: O-ring Inner diameter (mm) Thickness (mm) 131.60 2.62

2. caution Be careful not to damage the O-rings and the brake reaction sleeve. Coat the 2 new O-rings with ATF, and install them to the brake reaction sleeve. SIZE: O-ring Inner diameter (mm) Thickness (mm) 79.10 2.62 128.00 2.62

3. caution Be careful not to damage the O-rings and the Inner brake piston No. 4. Coat the 2 new O-rings with ATF, and install them to the inner brake piston No. 4. SIZE: O-ring Inner diameter (mm) Thickness (mm) 67.35 2.62 116.40 2.62 4.Coat the sliding surface of the transmission case with ATF.

5. caution Be careful not to damage the O-rings. Install the inner brake piston No. 4, brake reaction sleeve and reverse brake piston to the transmission case.

1.Install the low/reverse brake return spring sub-assembly.

2.Set the special tools as shown in the illustration, and compress the spring. Spring compressor body (MD998903) Retainer (MD998924) 3. caution Be careful not to expand the shaft snap ring too much. Using a screwdriver, install the shaft snap ring in the groove.

Adjustment of brake pack clearance and select the brake flange No. 4. (Refer to OIL PUMP AND CENTRE PLANETARY GEAR ASSEMBLY INSPECTION-INSPECT PACK CLEARANCE OF BRAKE (B4) )

1.Apply ATF to the thrust bearing race No. 9, thrust needle roller with race bearing and thrust needle roller bearing and install them to the RR planetary gear assembly.

2.Install the RR planetary gear assembly to the transmission case.

Install the 2 flanges, 8 discs and 7 plates to the transmission case as shown in the illustration. note Install the flanges, the discs and the plates following the order shown in the illustration.

1.Select a thrust bearing race which will make the gear spline piece axial play equal the standard value. Standard value: 0.02 - 0.12 mm

2.Install a thrust bearing race of the same size as having been used.
