Inspection of Ring Gear Mounting Case




1. MEASURE RING GEAR MOUNTING CASE
a. Using a cylinder gauge, measure the inner diameter of the mounting right case bushing.

Standard diameter: 69.000 - 69.035 mm
(2.7165 - 2.7179 in.)


Maximum diameter: 69.060 mm (2.7189 in.)




b. Using a cylinder gauge, measure the inner diameter of the mounting left case bushing.

Standard diameter: 69.000 - 69.035 mm
(2.7165 - 2.7179 in.)


Maximum diameter: 69.060 mm (2.7189 in.)




2. CHECK RING GEAR MOUNTING CASE RUNOUT

HINT: Perform only when the limit is exceeded in the ring gear runout inspection.

a. Using six bolts (Diameter 8 mm, Pitch 1.25 mm), install the mounting right case to the left case.

HINT: Align the matchmarks on the right case and connect the left case.




b. Using a dial indicator, check the mounting case runout.

Maximum runout: 0.1 mm (0.004 in.)

c. Remove the six bolts.
d. Remove the mounting right case from the left case.




3. MEASURE WASHER
Using a micrometer, measure the two washers thickness.

Standard thickness: 1.49 - 1.51 mm
(0.0587 - 0.0594 in.)


Minimum thickness: 1.45 mm (0.0571 in.)
