bearing 6 Inspect each part for wear, sur-
face defect and discoloration.
Replace with a new one if defective even within the wear
limit.
(a)Thrust bushing
Measure the distance between grooves (K) of the thrust
bushing, and replace with a new one if the wear limit is
exceeded.
Wear limit
RHF5 4.07 mm
RHB51 4.07 mm
RHB31 3.65 mm
(b)Oil thrower 2
Measure the seal ring groove widths (G1) and (G2), and replace with a new one if the wear limit is exceeded.
Wear limits
RHF5--- G1: 1.31 mm, G2: 1.11 mm
RHB51--- G1: 1.31 mm, G2: 1.11 mm
RHB31--- G1: 1.04 mm, G2: 0.84 mm
(c)Thrust bearing 6
Measure the thrust bearing width (J), and replace with
a new one if the wear limit is exceeded.
Wear limit
RHF5 3.98 mm

RHB31 3.58 mm
(7) Floating bearing 5
1)Inspect the floating bearing for abnormal wear,
discoloration or surface defect.
Replace with a new one if defective.
