Dear all,
Since I joined this forum, this picture ( Image 2 of 6) by Volker
jetronic.org/de/d-jetronic/einspritzventil#
has interested me. I've always wondered what an injector looks like from the inside.
To find out, I dismantled two stuck injectors. I completely dismantled the first one to see how it was crimped, and then I invented a small handy tool to try and remove the upper part without completely destroying the housing and connector.
The second picture shows the completely destroyed green connector and housing.
The first picture shows the tool in action, with the upper part positioned under the collar of the fuel intake line and the lower part resting on the original steel retaining ring.
The third picture shows the loose parts of the tool.
The last picture shows a nicely opened outer housing at the top and a complete intake line with coil and connector.
Ps. 1: In the last picture, you can see some sealing residue that had accumulated in the center section.
Ps. 2: The injectors can indeed rust from the inside, and rust residue accumulates in the center. This is trapped between the intake filter and the top of the needle.
Kind regards,
Marc
