采用 WEVB 系统后，排气门间隙的调整方法 ( 零件序号参见图 1)：
After WEVB system is used, the adjustment method of exhaust valve clearance is as
follows (see Fig. 2 for part serial numbers)
1、所要调整的气缸的活塞位于压缩行程上止点；
1. The cylinder piston to be adjusted is located on the top dead center of the compression
travel.
2、如图 2 所示 , 在序号 2 调节螺栓总成松开 , 不压紧排气门摇臂封油平面的情况下 ,
先通过调整推杆端序号 10 气门间隙调整螺钉 , 将总气门间隙调整为 0.4mm, 将防松螺母
拧紧。
2. As shown in Fig. 2, loosen No. 2 adjusting bolt assembly. In case that the oil seal plane
of exhaust valve rocker arm is not pressed, first by using No. 10 valve clearance adjusting screw
at the push rod end, adjust the total valve clearance to 0.4mm. Tighten check nut.
注意：调整过程中应转动气门间隙调整螺钉直到将塞规夹住 , 从而保证使序号 5 气
门摇臂活塞压到底，与排气门摇臂中的活塞安装孔底部平面之间无间隙；
Caution: During adjustment, turn the valve clearance adjusting screw until the clearance
gauge is clamped so that No. 5 valve rocker arm piston is pressed to its bottom. There is not
clearance between No.5 valve rocker arm piston and the piston installation hole bottom plane in
exhaust valve rocker arm.
3、然后如图 3 所示，在序号 5 气门摇臂活塞与排气门杆端或气门杆帽之间再放入
0.25mm 的塞规，通过调整序号 2 调节螺栓总成，将气门端间隙调整为 0.25mm, 将防松螺
母拧紧。
3. Then as shown in Fig. 3, insert the clearance gauge between No. 5 valve rocker arm
piston and the exhaust valve rod end or valve rod cap. By turning No.2 regulating bolt, adjust
the valve clearance to 0.25mm. Tighten check nut.
注意：调整过程中应转动序号 2 调节螺栓总成直到将塞规夹住，从而保证使序号 5
气门摇臂活塞压到底，与排气门摇臂中的活塞安装孔底部平面之间无间隙。
Caution: During adjustment, turn No. 2 regulating bolt until clearance gauge is clamped so
that No. 5 valve rocker arm piston is pressed to its bottom. There is not clearance between No.5
valve rocker arm piston and the piston installation hole bottom plane in exhaust valve rocker
arm.
