Service Tools

Usage:

325D L A3R
使用下列维修工具来帮助诊断和排除电气系统故障。

  • Caterpillar 电子技师(ET)3.2 版或以上版本

  • 146-4080 数字万用表或等效工具

  • 9U-7330 数字万用表或等效工具

  • 7X-1710 万用表表笔

  • 8T-8726 适配器缆线

  • 4C-3406 接头修理工具包

  • 276-7273 传感器测试箱

注: 传感器测试箱是用来测试 Caterpillar 油缸位置传感器的一种仪表。

有关 Cat-ET 的更多信息,请参阅故障诊断和排除, "使用 Caterpillar 电子技师(Cat-ET)确定诊断代码)"。 维修工具。

使用数字万用表来检查连续性或电压。 请参阅以下专门说明书以了解有关 6V-7070 数字万用表使用的更多信息。 请参阅专门说明书, SEHS7734, "6V-70706V-7800 万用表的使用"。 7X-1710 万用表表笔用来在接头处进行测量而无需断开接头。 将表笔沿导线推入接头背面中。 8T-8726 适配器缆线是一种 “3 针”叉接线束,用来测量传感器电路。

对于现代 Caterpillar 电路,除线束测试外,不推荐使用某些测试设备。 此类测试仪包括下列示例: 8T-0500 导通性测试仪 和 5P-7277 电压测试仪。

注: 用于测试"缸内"位置传感器的步骤已经开发出来。 请参阅专门说明书 REHS7338, "测试液压油缸位置传感器的步骤"。
