Od Planetary Gear, Od Direct Clutch & Od One-Way Clutch: Reassembly
WARNING: This page does not describe the selected car, but rather 22 other vehicles, including the 2005 Lexus SC 430, 2005 Lexus IS 300, 2005 Lexus GS 430, 2005 Lexus GS 300, and 2004 Lexus SC 430. However, it is still accessible from the selected car via links, so may be relevant.
- Position planetary gear with input shaft pointing upward. Install thrust washer in planetary gear with grooved side facing upward. Install one-way clutch into outer race with flanged side facing upward. See Fig 3.
- Install one-way clutch assembly on planetary gear. Install retaining plate and snap ring. Install race on back of planetary gear. Race tabs must be engaged in planetary gear. See Fig 1.
- Install ring gear flange and snap ring. Install thrust bearing and race in planetary ring gear. Race tabs must be engaged in ring gear. Coat "O" rings with ATF and install on clutch piston. Carefully install clutch piston in clutch drum. Install piston return spring. Using appropriate compressor, compress return spring and install snap ring. Ensure ring is fully seated.CAUTION: Ensure ends of snap ring do not align with claw area on spring retainer of piston return spring.
- With clutch drum open area facing upward, install plates and discs, starting with plate. Install flange with flat end facing toward disc. Install snap ring. Place oil pump on torque converter. Place clutch drum onto oil pump. Measure piston stroke while applying 57-114 psi (4-8 kg/cm2 ) to oil pump port. See Fig 2. Piston stroke should be .033-.043" (.85-1.10 mm). If piston stroke is not within specification, check for incorrectly assembled components. Recheck piston stroke.
- If piston stroke exceeds specification, install different thickness flange. Flanges are available in thicknesses of .122" (3.09 mm) to .151" (3.80 mm) in .004" (.10 mm) increments.
- Remove clutch assembly from oil pump. Install thrust bearing and race in clutch drum with race toward clutch drum. Align tabs of clutch discs. See Fig 1. Install direct clutch drum on planetary gear. Hold clutch drum and rotate input shaft clockwise. Input shaft should rotate freely clockwise and lock counterclockwise. See Figure.
