2. GRIND CRANK PIN AND/OR MAIN JOURNAL IF NECESSARY Grind the crank pins and/or main journals to the undersized finished diameter. Install a new pin and/or main undersize bearings. Bearing size (U/S 0.25, 0.50) Main journal finished diameter: U/S 0.25 59.730 — 59.740 mm (2.3516 — 2.3520 in.) U/S 0.50 59.480 — 59.490 mm (2.3417 — 2.3421 in.) Crank pin finished diameter: U/S 0.25 51.725 — 51.735 mm (2.0364 — 2.0368 in.) U/S 0.50 51.475 — 51.485 mm (2.0266 — 2.0270 in.) Taper and out-of-round limit: 0.02 mm (0.008 in.) INSPECTION AND REPAIR OF OIL PUMP DRIVE SHAFT COMPONENTS 1. INSPECT OIL PUMP DRIVE SHAFT (a) Using a micrometer, measure the journal diameter. Standard journal diameter: Front 40.959 — 40.975 mm (1.6126 — 1.6132 in.) Rear 32.959 — 32.975 mm (1.2976 — 1.2982 in.) (b) Using a cylinder micrometer, measure the bearing bore. (c) Subtract the journal diameter measurement from the bearing bore measurement. Standard oil clearance: 0.025 — 0.066 mm (0.0010 — 0.0026 in.) Maximum oil clearance: 0.08 mm (0.003 in.) If the clearance is greater than maximum, replace the bearing and/or drive shaft. 2. IF NECESSARY, REPLACE DRIVE SHAFT BEARING (a) Using SST, replace the No. 1 bearing, using the No. 2 bearing as a guide. SST 09215-00100 (09215-00120, 09215-00150, 09215-00160, 09215-00210, 09215-00220) No. 1 Bearing Replacement SST No. 2 Bearing No. 1 Bearing Front EM1756 EM1744 EM1753
