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.
Pinion gear end play: 0.1 - 0.7 mm (0.004 - 0.028 inch)
^ 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 inch) 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.
