This is auto repair but it’s more general.
I’m trying to reseal a diesel injection pump. One of the T30 screws was messed up and stripped. My attempt only made it worse.
A rocket socket made short work of the removal. The cover is keeping oil in this:
I also removed the back plate to seal that. Also T30. Of course the two screw types are different.
I need the one on the right. The threads on both screws are the same. But the one on the right has that little flat top. Why?
The screw barely appears from the top…
I can apply torque to the buggered threads for loosening and tightening. They were just too hard in there after 32 years.
Is this a special variety of screw? I’ve seen them before but don’t know their name.
Do I dare use it again with some antiseize and some more on the hole on the top? I can’t imagine that I should be tightening any of these very much. I have no spec.
Thoughts?
Thanks!
