EM-80 ENGINE MECHANICAL — Cylinder Block (b) Inspect the oil clearance between the rod bushing and piston pin. • Using a caliper gauge, measure the inside diameter of the connecting rod bushing. Bushing inside diameter: 22.005 — 22.017 mm (0.8663 — 0.8668 in.) • Using a micrometer, measure the piston pin diameter. Piston pin diameter: 21.996 — 22.009 mm (0.8660 — 0.8665 in.) • Subtract the piston pin diameter measurement from the bushing inside diameter measurement. Standard oil clearance: 0.005 — 0.011 mm (0.0002 — 0.0004 in.) Maximum oil clearance: 0.02 mm (0.0008 in.) If the oil clearance is greater than maximum, replace the bushing. If necessary, replace the piston and piston pin assembly. 7. IF NECESSARY, REPLACE CONNECTING ROD BUSHING (a) Using SST and a press, press out the bushing. SST 09222-30010 (b) Align the oil holes of a new bushing and connecting rod. (c) Using SST and a press, press in the bushing. SST 09222-30010
