三、气门间隙、减压机构和供油提前角的调整 1.气门间隙的调整 (1) 拆下气缸盖罩,检查并拧紧气门摇臂轴支座的压紧螺栓和螺母。 (2) 将曲轴转到第一缸活塞处于上止点位置,此时,曲轴皮带轮上“0”线正好与正时齿轮室盖上的指针对准,且飞轮壳上观察窗处的记号,正好对准飞轮上“0”刻线。 (3) 用厚薄规分别插入第一缸进、排气门与摇臂之间,检查并调整进、排气门间隙,保持冷态间隙分别为0.20～0.25毫米和0.25～
Third, the valve clearance, decompression mechanism and fuel supply advance angle adjustment 1. Valve clearance adjustment (1) Remove the cylinder head cover, check and tighten the rocker valve shaft bearing pressure bolts and nuts. (2) Turn the crankshaft to the position where the piston in the first cylinder is at the top dead center. At this time, the “0” line on the crankshaft pulley is aligned with the pointer on the timing gear chamber cover and the Mark, just align the flywheel on the “0 ” engraved line. (3) with thickness gauge were inserted into the first cylinder into the exhaust valve and rocker arm, check and adjust the intake and exhaust valve clearance, keep the cold clearance of 0.20 to 0.25 mm and 0.25 ~
