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 specifica-

tion, 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 pas-
sage 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.
