SPECT VALVE CLEARANCE (a) Turn the crankshaft pulley, and align the timing notch with timing mark 0 of the timing belt cover. (b) Check that the valve lifters on the ( and ) are both loose. If not, turn the crankshaft revolution (0 ) and align the mark as above. P880 0

SST ( , ) HT: Apply at a slight angle on the side marked with 9 or 7 at the position shown in the illustration. When is inserted too deeply, it will get pinched by the shim. To prevent it from being stuck, insert it gently from the intake side at a slight angle. 9 A7870

Magnetic Finger A787 EM0494 (e) (f) (g) Using a micrometer, measure the thickness of the removed shim. Calculate the thickness of a new shim so that the valve clearance comes within the specified value. A B C of new shim of used shim Measured valve clearance Specified value (Cold): Intake A = B + (C 0.0 mm ( in.)) Exhaust A = B + (C 0.0 mm (0.08 in.)) Select a new shim with a thickness as close as possible to the calculated values. AMPLE (Intake): Measured valve clearance = 0.4 mm (0.077 in.) 0.4 mm (0.077 in.) 0.0 mm ( in.) = 0. mm ( in.)
