2. Measure outside diameter “D” of piston pin. Connecting rod small end bushing clearance = A − D Standard 0.025 - 0.043 mm (0.0010 - 0.0017 in) Limit 0.15 mm (0.0059 in) REPLACEMENT OF CONNECTING ROD BUSHING 1. Drive in the small end bushing until it is flush with the end sur- face of the rod. Be sure to align the oil holes. Small end bushing inside diameter: Finished size 30.025 - 30.038 mm (1.1821 - 1.1826 in) CRANKSHAFT 1. Check crankshaft journals and pins for score, bias, wear or cracks. If faults are minor, correct with fine emery paper. 2. Check journals and pins with a micrometer for taper and out- of-round. Out-of-round (X − Y): Standard Less than 0.01 mm (0.0004 in) Limit 0.02 mm (0.0008 in) Taper (A − B): Standard Less than 0.01 mm (0.0004 in) Limit 0.02 mm (0.0008 in) 3. Check crankshaft runout. Runout (Total Indicator Reading) Standard 0 - 0.03 mm (0 - 0.0012 in) Limit 0.10 mm (0.0039 in) SEM416B EM715 SEM662B ENGINE OVERHAUL TD27Ti Inspection (Cont’d) EM-130 |
