1、首先把手动叉车手柄压下,拿一个卡扣工具来扣住活塞杆大弹簧,把链条从手柄销内取出来;

2、用冲针把开口销打下来,取出手柄销,取下手柄总成;

3、再取下卡扣工具,取出大弹簧和活塞杆,其次就是松开叉车大活塞主顶杆上面的螺丝,把叉车翻过来,再取下大活塞主顶杆,就可以看到里面的活封修理包了;

4、把旧的油封用螺丝刀和钳子取出来,再装回新的油封。在气温比较高时候,手动叉车的油封会比较好取出。而气温太底时手动叉车的油封会僵硬,不易取出及安装进去。此时,可以给油封稍微加下热然后用起子一点一点磨蹭进去,当手动叉车油封安装好后用手感觉一下平滑度,确认无误后把活塞杆按原样装回去就可以了。

手动叉车的油封它的主要功能是用来封油(油是叉车传动系统中最常见的液体物质,也泛指一般的液体物质之意)的机械元件,它将传动部件中需要润滑的部件与出力部件隔离,不至于让润滑油渗漏。静密封和动密封(一般往复运动)用密封件叫密封件。在安装的时候要注意以下几点: 

1、安装叉车油封修理包/密封件前必须确保密封油槽中没有杂质和裂纹; 

2、分别在叉车油封修理包的密封油槽和密封件表面涂上操作油(液压油); 

3、按照顺序逐渐安装叉车油封修理包/密封件; 一般旧叉车用久后都有少许磨损,建议更换油封时选用进口油封比较好用又耐用些;

4、安装过程中应该避开凌锐边,扶正密封件,避免扭曲及歪斜; 

5、若是分体槽,最后上紧压盖。
