It has been many months since I have messed with my 87 300td to get it running. If you are interested - this was the thread.

After rebuilding the injectors Sean Watts came over to the house and helped me narrow it down to the injection pump. He was able to get me a really great pump by Monark, direct from Germany- MB's supplier now. What a nice unit!
Anyway, while removing the vacuum pump we noticed that the timing chain holder ("assembly basket"-held in by three bolts) was already in the car! I'm pretty sure it was not supposed to be there and maybe left there by a prior mechanic. I bought this tool thinking I needed to support he chain when the pump comes out. Since I had the old style vac pump I went to the local wrecker who has this engine and removed his newer vacuum pump. I was shocked to see that same retainer piece in that car too.
IS THIS SUPPOSED TO BE THERE or should it come out? -See picture- I can't imagine two mechanics left them in, or is is suposed to be there?
I'm ready to assemble now but need to be sure. Any help would be great
