Diesel Injector Fuel Injector 0445110369 Bosch for Audi, VW

Reason 2: The disassembly space of the fuel injector pulling tool is limited, and it is difficult for personnel to cooperate with the disassembly
The whole process of dismantling the fuel injector must be completed on the main engine body. The space above the cylinder head is small, and it is difficult to cooperate with personnel to disassemble. Due to the impact of objective environment, personnel communication and cooperation are prone to mistakes, which prolongs the disassembly time. 10 times were taken to dismantle the fuel injector by the personnel on the post, and 2 mistakes were made. The results showed that at least two people were required to cooperate to complete the disassembly of the fuel injector, and the cooperation and communication error rate of one disassembly process was ≤ 30%, so it was confirmed as a non-factor.
Reason 3: The drawing tool has no base, the space is narrow, the centering is difficult, and the installation time is long
When the old drawing tool structure was designed, the part connected to the injector at the bottom did not have a base, so that when installing the drawing tool, personnel had to judge the relative positional relationship between the drawing tool and the injector by naked eyes and experience to complete the drawing tool. installation. In order to confirm the actual time spent on the installation of the drawing tools by the personnel in the post, statistics were made on the installation of the personnel in different positions, as shown in Figure 1. The data shows that it takes about 120 seconds for the post personnel to install the pulling tools, which is less than the target of 60 seconds. Therefore, this factor is confirmed as the main cause.
