Planetary Carrier: Disassembly and Assembly

Disassembly

1) Remove the snap ring.





2) Remove the sun gear assembly from the planetary carrier assembly using suitable tool.
3) Remove the snap ring from the sun gear assembly using suitable tool.





4) Remove the carrier bearing from the sun gear using Tools.











5) Remove the needle bearing from the sun gear using Tool.











6) Remove the metal bushing from the sun gear using Tools.











Inspection after Disassembly

Bearing

Check the bearing for damage and rough rotation. If necessary, replace the bearing with a new one.





Planetary Carrier

- Measure the end play of each pinion gear. If it is out of specification, replace the planetary carrier assembly with new one.











- Check the working face of each gear and bearing for damage, burrs, partial wear, dents and other abnormality. If any is found, replace the planetary carrier assembly with a new one.

Sun Gear

- Check if the oil passage of the sun gear assembly is clogged. For this, try to pass a 3.6 mm (0.142 in) dia. wire through the oil passage as shown.





- Check the sliding and contact surface of each gear and bearing for damage, burrs, partial wear, dents and other abnormality. If any is found, replace the sun gear assembly with a new one.

Internal Gear

Check the internal gear teeth for damage, partial wear, dents or other abnormality. If any is found, replace the internal gear with a new one.






Assembly

1) Apply ATF to the new metal bushing, then install the new metal bushing until it becomes Dimension (A) using Tool.















CAUTION:
Do not reuse metal bushing.

2) Apply ATF to the new needle bearing, then install the new needle bearing until it becomes Dimension (B) using Tool.















CAUTION:
Do not reuse needle bearing.

3) Install the carrier bearing to the sun gear using Tools.











4) Install the new snap ring to the sun gear assembly using suitable tool.






CAUTION:
Do not reuse snap ring.

5) Install the sun gear assembly to the planetary carrier assembly.





6) Install the new snap ring to the planetary carrier assembly.

CAUTION:
Do not reuse snap ring.
