2. Measure the inside diameter (Figure 9-3, (C))
and outside diameter (Figure 9-3, (D)) of the
bearing. If measurements exceed the wear
limit, replace the floating bearing.
• Wear limit: Outside diameter: 15.98 mm
(0.629 in.)
• Wear limit: Inside diameter: 11.46 mm
(0.451 in.)
Bearing Housing
1. Check the casting surfaces for damage,
separation, dents and cracks caused by
corrosion. Replace the bearing housing
(Figure 9-2, (51)) if necessary.
2. Check the retaining ring (Figure 9-2, (52)) for
breakage and cracks. Replace the retaining
ring if necessary.
3. Measure dimensions (Figure 9-7, (B)) and
(Figure 9-7, (F)) of the bearing housing.
Replace the bearing housing if either measured
value exceeds the wear limit.
• Bearing housing inside diameter
(Figure 9-7, (B)) Wear limit: 16.11 mm
(0.634 in.)
• Seal ring insertion hole on turbine side
(Figure 9-7, (F)) Wear limit: 17.03 mm
(0.670 in.)

damage, contact traces, defects, dents or
cracks of the mating surfaces. Replace the seal
plate if necessary.
