INSPECTION AFTER DISASSEMBLY
Bearing





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

Planetary Carrier





^ Measure end play of each pinion gear, and make sure the measurement is within specification shown below. If out of specification, replace planetary carrier with new one.
Pinion gear end play: 0.1 - 0.7 mm (0.004 - 0.028 inch)
^ Check working face of each gear, bearing and others for damage, burrs, partial wear, dents and other abnormality. If any is found, replace planetary carrier with new one.

Sun Gear





Check items below. If necessary, replace them with new ones.
^ If oil passage of sun gear is clogged. For this, try to pass a 3.6 mm (0.142 inch) dia. wire through 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.
