How much does a D4 tranny case wiegh?

I need to find out how much a bare bones D4 6U/7U transmission case wieghs. Do any
of you know?

Thanks for any help on the matter, Josh

Josh-
I have Form 8480 Parts Section for the D4 Tractor from 7J6753 through all 2T series published in March 1944, so it is a little earlier than your 6U / 7U question I think. However, this is what I find for the one piece cover 1F9540 reads 240 pounds. FYI the list price in 1944 was $61.60.

Seems like mine was heavier than that, but I had all the controls, levers and shifter assembly attached. The weight given above appears to be without anything attached.

I hope this helps-I really enjoy looking through this manual...
