8. TURBOCHARGER (6) Thrust bushing, oil thrower (2) and thrust bear- ing (6) Inspect each part for wear, surface 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 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 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 RHB51..... 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. 2) Measure the inside diameter (C) and outside diameter (D). Replace the bearing if either wear limit is exceeded. Wear limits RHB51..... Outside diameter (D): 12.31 mm, Inside diameter (C): 8.04 mm RHB31..... Outside diameter (D): 9.93 mm, Inside diameter (C): 6.29 mm 8-14 82E-5 – 98E-5 SERIES
