Steering Time - Check - STIC Steering
- 将机器停放在坚硬、干燥和水平的地面上。
- 确保转向机架锁处于储存位置。
- 以高怠速运转发动机。 将操纵手柄移到后倾位置，以便将油温升至正常工作温度。
- 将作业机具从地面升离约 300 mm (12 in)。
- 将变速箱置于空档位置。
注: 液压控制装置也应处于空档位置。
- 松开停车制动器。
- 释放行车制动器。
- 向左或向右铰接机器，直到机器停止铰接。
- 发动机处于高怠速时，最大限度移动 STIC 转向操纵杆并向相反方向铰接机器，直到机器停止铰接。 将结果记录下来。
注: 机器开始铰接时，开始测量转向时间。 转向时间测量到机器停止铰接为止。
- 重复步骤 10 以检查相反方向的转向时间。 将结果记录下来。
- 接合停车制动器，将作业机具降至地面。
- 停止发动机。
- 每个方向的转向时间应为 3.2 ± 0.3 秒。 左转向时间和右转向时间的差值也应在 0.0 至 0.3 秒之间。 如果转向时间不正确，检查以下条件：
- 检查转向安全阀。
- 检查转向泵流量。
- 检查先导油压。
- 检查转向控制阀中的滑阀。
- 检查转向油缸活塞密封。
- 检查转向安全阀。
- 若问题仍未纠正，参阅步骤16至步骤 17。
- 左转向时间和右转向时间的差值应在 0.0 至 0.3 秒之间。 如果转向时间不正确，则需要调节流量平衡垫片。
- 每个方向的转向时间应为 3.2 ± 0.3 秒。
