ADJUSTMENT

Note. Adjustment of valve clearance should be performed while engine is cold.

Scheme 76
  1. Set #1 cylinder piston to top dead center of compression stroke by rotating the crank pulley clockwise using the socket wrench. NOTE: When the arrow mark (A) on cam sprocket LH is at the top position, the #1 cylinder piston is at top dead center of the compression stroke.
  2. Adjust the #1 cylinder valve clearance. Loosen the valve rocker nut and screw. Set a suitable thickness gauge. While noting the valve clearance, tighten the valve rocker adjusting screw. When the specified valve clearance is obtained, tighten the valve rocker nut. NOTE: Insert a thickness gauge in a direction as horizontal as possible with respect to the valve stem end face. Lift up the vehicle and adjust the exhaust valve clearances. Valve clearance: Intake 0.20±0.04 mm (0.0079±0.0016 in) Exhaust 0.25±0.04 mm (0.0098±0.0016 in) Tightening torque: 9.75 N.m (1.0 kgf-m, 7.2 ft-lb)
  3. Adjust the valve clearance in #3, #2 and #4 cylinder in the same adjustment procedure as #1 cylinder in this order. NOTE: Be sure to set the cylinder pistons to their respective top dead centers on compression stroke before adjusting valve clearances. By rotating the crank pulley clockwise every 180° from the state that #1 cylinder piston is on the top dead center of compression stroke, #3, #2 and #4 cylinder pistons come to the top dead center of compression stroke in this order.
  4. Ensure the valve clearances of each cylinder are within specifications. If necessary, readjust the valve clearances.
