ENGINE – ENGINE MECHANICAL EG–113 CRANKSHAFT INSPECTION 1. INSPECT CRANKSHAFT FOR RUNOUT (a) Place the crankshaft on V–blocks. (b) Using a dial indicator, measure the circle runout at the center journal. Maximum circle runout: 0.06 mm (0.0024 in.) If the circle runout is greater than maximum, replace the crankshaft. 2. INSPECT MAIN JOURNALS AND CRANK PINS (a) Using a micrometer, measure the diameter of each main journal and crank pin. Main journal diameter: STD 61.984–62.000 mm (2.4403–2.4409 in.) U/S 0.25 61.745–61.755 mm (2.4309–2.4313 in.) Crank pin diameter: STD 51.982–52.000 mm (2.0465–2.0472 in.) U/S 0.25 51.745–51.755 mm (2.0372–2.0376 in.) If the diameter is not as specified, check the oil clearance. (See steps 3 and 6 in cylinder block disassembly) (b) Check each main journal and crank pin for taper and out–of–round as shown. Maximum taper and out–of round: 0.02 mm (0.0008 in.) If the taper or out–of–round is greater than maximum, grind or replace the crankshaft. 3. IF NECESSARY, GRIND AND HONE MAIN JOURNALS AND/OR CRANK PINS Grind and hone the main journals and/or crank pins to the finished undersized diameter (See procedure step 2). Install new main journal and/or crank pin undersized bearings. P02153 P02081 EM0315 Z02383
