It is. I think the other thing they're describing is just a puller. I've been waiting for the MAN tech to get back to me... still waiting.
10-4 on the slide hammer. Iv'e seen a few examples of that tool used with lug nuts or a recycled flare nut welded on
Nothing yet. I put in another call, hopefully he'll check in soon.
Thanks, standing by.
Well that worked much better on the second try. He said that the tool you're showing in that kit on the lower left allows you to use the castle nut to pull the injector. It threads on to the line fitting and then unscrewing the retaining nut should break the injector loose. He also said they can be quite difficult to remove and the tools break a lot. Hopefully you started a long time ago with the penetrating oil.
My advice: if you're going to try to pull them with the retaining nut I'd take the nut out first and put a lot of heavy lubricant like grease or never-seez on the threads to help prevent them from galling. You don't want to booger up the threads in the head.
Thank you for chasing this down. So then it looks like the reason for the two simultaneous wrenches shown in the removal picture is that the top wrench is holding the fuel line fitting attachment in place while the lower wrench is turning the outer sleeve which drives the castle nut up and out? Is that how you understand it?
Do you know why they also use the slide hammer approach?
Thanks,

Looks like you've got it. I'd guess they recommend the slide hammer because you can apply force without the risk of stripping the threads. Also, when dealing with frozen components there's a lot to be said for shock value.
