EM-124 < UNIT DISASSEMBLY AND ASSEMBLY > CYLINDER BLOCK • Measure the outer diameters (A), (B) at two positions as shown in the figure. • If reduction appears in (A) range, regard it (B). • If it exceeds the limit (large difference in dimensions), replace main bearing cap sub bolts with new one. CONNECTING ROD BOLT OUTER DIAMETER 1. Measure the outer diameters [(a), (b) and (c)] at the position 2. Obtain a mean value (d) of (a) and (b). 3. Subtract (c) from (d). 4. If it exceeds the limit (large difference in dimensions), replace the bolt with new one. DRIVE PLATE • Check drive plate and signal plate (A) for deformation or damage. CAUTION: • Never disassemble drive plate. scratch it. • Handle signal plate in a manner that prevents it from becom- ing magnetized. • If damage is found, replace drive plate. OIL JET • Check nozzle for deformation and damage. proper reaction force. • If it is not satisfied, clean or replace oil jet. c : 20 mm (0.79 in) d : 15 mm (0.59 in) e : 9 mm (0.35 in) Limit [(B) – (A)] : 0.10 mm (0.0039 in) JPBIA2280ZZ a : Value at the end of the smaller diameter of the bolt b : Value at the end of the smaller diameter of the bolt [opposite side of (a)] c : Value of the smallest diameter of the smaller of the bolt Limit [(d) – (c)] : 0.08 mm (0.0032 in) JPBIA0262ZZ B : Ring gear : Engine front JPBIA2282ZZ |
