That describes most Onans of all different sizes.
But I'm just exploring some optins.
I have a good working BF which i can make fit into my generator space with a bit of persuasion.
But if the BF is the base of the 4000 power drawer then i wonder if i could swap the externals?
Dave,
As I understand from doing parts hunting years ago, the engine designation of BF is for all of those engines of that design. As long as it is a BF, it is the same as every other BF except for some external dress. Three things that I do know are special about the PDs are:
1- They draw the cooling air over the engine instead of blow.
2- They are set up for fuel pump and not gravity feed.
3- They have a control board with safeties to enable remote operation.

So, I bet if you can find a Power Drawer with a bad engine, you could swap yours in there.

Matt
