TM 9-2815-226-34-1k. Measure crankshaft bearing journals for wear, out-of-round, or taper. If wear exceeds 4.4975 in. (114.2365 mm)or journal out-of-round more than 0.002 in. (0.050 mm) or tapered more than 0.0005 in. (0.0127 mm), crankshaftmust be ground to accept undersize bearings.l. Measure crankshaft rod bearing journals for wear, out-of-round, or taper. If wear exceeds 3.122 in. (80.30 mm) orjournal out-of-round more than 0.002 in. (0.05 mm) or taper more than 0.0015 in. (0.013 mm), crankshaft must beground to accept undersize rod bearings. Oversizes are available in 0.010, 0.020, 0.030, and 0.040 in. (0.254,0.508, 0.764, and 1.016 mm).NOTE:EXAMPLE SHOWS MAINBEARINGS ARE STANDARDAND ROD BEARINGS ARE0.010 IN.
