用国产件修复进口转向助力泵

Domestic Made Power-assisted Steering Hydraulic Pump Replace the Imported One

配备五十铃6BG1柴油机（6缸）的“沈飞”客车是一种较为常用的客车，有一定的市场占有量。该车配有“液压常流整体式助力转向”装置，该装置的外廓尺寸小，质量轻，结构紧凑，管路易于布置：但在使用两三年后，出现转向沉重的故障较频繁，在实际检修中发现，通常是由助力液压泵工作失效造成的，致使助力转向器变成机械转向器，此时转向十分沉重，

The article introduced the process of replacing the broken power-assisted steering hydraulic-pump imported from Japan with the domestic one for ISUZU 6BG1 engine incorporated on Shengfei passenger bus. It is proved that Chinese domestic made product is durable and the replacement process is cost-effective, which could be a good example and reference for other manufacturers.
