EM-10 ENGINE MECHANICAL — Engine Tune-Up (b) Determine the replacement shim size by using the following (Formula or Chart). • Using a micrometer, measure the thickness of the shim which was removed. • Calculate the thickness of the new shim so the valve clearance comes within specified value. T ........ Thickness of shim used A ........ Valve clearance measured N ........ Thickness of shim new Intake side: N = T + (A - 0.20 mm (0.0079 in.)) Exhaust side: N = T + (A - 0.25 mm (0.0098 in.)) • Select a new shim with a thickness as close as possible to the calculated value. HINT: Shims are available in 17 sizes, in increments of 0.050 mm (0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299 in.). (c) Install the new adjusting shim. • Place the new adjusting shim on the valve lifter. • Using SST (A), press down the valve lifter and remove SST (B). SST 09248-55010 (d) Recheck the valve clearance. 7. INSTALL CYLINDER HEAD COVERS (See step 4 on pages EM-55, 56) 8. INSTALL AIR INTAKE CONNECTOR (a) Install a new gasket and intake connector with the four bolts and two nuts. Torque: 180 kg·cm (13 ft-lb, 18 N·m) (b) Install the air intake connector bracket mounting bolts. EM0432 EM0472 EM3439 EM3479 SST(B) SST(A)
