注意

在检验、保养、测试、调整及维修产品时,务必留心,确保液体盛装在容器中。 在打开任何腔室或拆解任何储有液体的部件之前,要准备好用合适的容器收集液体。

有关适合收集和盛接卡特彼勒产品上液体的工具及用品,参考专门出版物, NENG2500, "卡特彼勒工具和修理车间设备指南"。

按照当地法规和指令处置所有液体。


注: 为了检查转向时间,将机器停在干燥、坚固、水平的地面上。

发动机高怠速运转时, 834H 轮式推土机的左右止点之间一整圈的转向时间应为 3.1 ± 0.8 秒。 发动机低怠速运转时,左右止点之间一整圈的转向时间应为 5.7 ± 0.9 秒。

发动机高怠速运转时, 836H 垃圾填埋压实机的左右止点之间一整圈的转向时间应为 3.9 ± 0.8 秒。 发动机低怠速运转时,左右止点之间一整圈的转向时间应为 6.4 ± 1.0 秒。

当未踩下行车制动器时,右转向时间和左转向时间之差不得超过 0.3 秒。 当踩下行车制动器时,增加的转向时间不得超过 0.2 秒。

如果向右转向一整圈和向左转向一整圈的时间之差超过了 0.3 秒,使用以下步骤调整转向时间:

转向控制阀

(1) 控制阀。 (2) 流量平衡垫片。 (3) 弹簧。 (4) 先导油端口。

注: 上面显示的是标准转向控制阀。 但辅助转向控制阀与此相似。

  1. 从转向控制阀的先导油端口 (4) 上拆下接头。

  1. 为了达到更快的右转向和更慢的左转向,添加流量平衡垫片 (2) 。 如果拆下流量平衡垫片 (2) ,结果相反。

  1. 每个 4J-8224 垫片 的厚度为 0.25 mm (0.010 in)。 每个 5J-4776 垫片 的厚度为 0.30 mm (0.012 in)。 两个垫片(每种厚度一个垫片)在高怠速下的转向时间约改变 0.1 秒。

  1. 将接头和管路安装至先导油端口 (4) 。
