pmk Posted November 6, 2016 Report Share Posted November 6, 2016 I have studied the parts diagram and notice there is a plastic tube inside the gearbox with slotted ends that serves as a gearbox breather. In my cleaning up of this old machine, removing concrete like mud, I have yet to find where this breather vents to ambient outside air. Could someone please explain where the gearbox breather vents externally? Thanks Quote Link to comment Share on other sites More sharing options...
t20racerman Posted November 7, 2016 Report Share Posted November 7, 2016 I remember looking at this when I rebuilt mine. I remember being puzzled by it and then going 'Oh, that makes sense..' Sadly, I'm struggling to remember exactly what I saw... I seem to remember that the casing bolt hole is wider than normal and allows the air to go along the side of the bolt. That's all I can remember though! Sorry. Can you post a pic to jolt my memory? Quote Link to comment Share on other sites More sharing options...
pmk Posted November 9, 2016 Author Report Share Posted November 9, 2016 Found it. As mentioned, the case breathes via a small passageway at the center case screwhead above the countershaft. 2 Quote Link to comment Share on other sites More sharing options...
