I have a mac 740 99cc. it still has original 25" bar and chain on it. Chain broke today and i have decided i want to put a new 36" bar on it to make it easier to match up gauge and pitch. I heard that orgeon bought out a good part of mcchulloch but i can't seem to find if their bars will match my 740. any help will be appreciated. Also any one know what the original pitch and gauge for a 25"? the bar measures 28" but i am assuming that they measure it by how much of the bar is actually a working edge.
