Hi all
Have a question on the exhaust brake. Can you move the butterfly in the exhaust opening by hand? I had a crack in the flex pipe and removed it, and then tried to move the butterfly and I could not move it.It did not work when I picked it up on Sunday and I new it did not work because of the bad line.(I had to replace the air hose it melted from the hot exhaust) I have read in the past that you have to keep the brake lubed up. I may unhook the air ram that works the brake but it is hard to get to. if I could find out if it can be
moved by hand with the ram connected if not I will have to remove it because I cant move the butterfly at all. any thoughts? :-\
Just a side note. I asked a cummins mechanic and he said that he never tried to move one . Now I know why I do all my own work
