Measure inner diameter of planetary carrier bushing: Carry out
several measurements using Dial Gauge MKM-571-B and probe for inner
diameter and determine average. Measurement value 30.0 to 30.03 mm
– if necessary, replace planetary carrier assembly (1).
Measure inner diameter of sun gear bushing: Carry out several
measurements using Dial Gauge MKM-571-B and probe for inner
diameter and determine average. Measurement value: 21.50 to 21.53
mm – if necessary, replace sun gear (2).
