Hello folks,  I'm wondering on d4 7u dash, is there a cover over the magnito that is part of the dash. I have parts book, it shows dash in profile, I'm not sure if there's a cover plate?

Ok Neil, this D4 I purchased is very complete. The air cleaner was off when I bought it so I really noticed the hole in dash. If there was a cover originally, I think it is the only part missing from this machine. Thanks.

no cover for that opening. I have seen some real early J series D2's with a cover over the mag hole but never on a 7U D4

If your dozer was equipped to have a cover plate for the mag hole in the dash, there would be a slot above the hole, and a bolt hole with a nut below the square access hole.
The cover plate was available for at least some of the J model D2s but I don't see any of the other tractors equipped to accept the cover.
I do have one on one of my D2 Js, they are a pain to put on and of no real use, and on the U models might be impossible to put on or remove without pulling the air cleaner and would not be removable with the crossover pipes for the dozer in place.

Scott Flint (RIP) had made some stainless steel cover plates in the past. I agree with Josh, a bit of a pain to have and the air cleaner is usually in the way. It would make the dash a little tidier (no spark plug ends visible.
Now I am thinking the direct electric machines would not have the pony flywheel cut out as well as for the magneto...smooth. JM
