Kohler Magnum breather

Recommended Posts


Does anyone know if the crankcase breather from an MV18 (vertical) will function properly on a horizontal M18? They are different part numbers but the only difference I can see (from pics online) is that the reed is going to the left on one and to the right on the other. I can see why the vertical application requires this as oil would run through it due to gravity but on a horizontal application the breather is on the top of the engine so I'm thinking its orientation shouldn't matter? My problem is I am getting some drops of oil in the air cleaner housing.

Although I could not say for certain, I believe it would not matter on the horizontal. I think the breather can be installed either way on the horizontal, so if it's the same size and configuration, I don't know why it wouldn't work. Caveat: I have no experience with the verticals.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
