ADJUSTMENT
Note. Adjustment of valve clearance should be performed while engine is cold.
Scheme 53
- 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) comes exactly to the top, #1 cylinder piston is brought to the top dead center of compression stroke.
- 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. Tightening torque: 9.75 N.m (1.0 kgf-m, 7.2 ft-lb) 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)
- 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.
- Ensure the valve clearances of each cylinder are within specifications. If necessary, readjust the valve clearances.
