Anyone have one of these Kohler breather covers from Kirk engines? I messaged them two days ago with no answer yet on buying it cheaper options and considering making one, but dont know if the back side is recessed or flat on this aftermarket part, or if it would even matter... Oem would be recessed on the back by design... Obviously easier to buy, but seems simple enough to make...

I'd be makin that if I needed one. Isn't the hose outlet suppose to be below the nut that holds the cover on. I could be wrong on that thou. And some hoses go into the carb or air cleaner to reburn base fumes.

you can not use just any old plastic.

it need to be high temp plastic

 

yes the outlet hole for the JD 200 series is below the nut and on other that connect to the air cleaner

 

I have replaced the tube from the breather to the air cleaner using a 1/4" gas line.

you have to shape both ends to fit.

How think does it have to be if flat? I would think 3/16" would be minimum to get threads in it, but would it need to be 1/4" or more? I would probably make one out of steel...

i would think 3/16 with be fine as long as you dont over do it when your tightening the fitting in, the one they sell is aluminum but steel would work just fine. the vent on a cub is above the bolt.

Would the aluminum be strong enough to seal the gasket. Steel one won't bend as much as aluminum.

I have on my 120 and installed one on the Killer Kohler I built.  Well made piece and it is recessed on the back side.  As for Dave's response - He works another job so his response can be delayed.  Give him a chance to juggle hats.  Do you want to see pics of it installed or want me to remove it for pics of the back side?

Those covers are flat,  & easily fabricated from steel or aluminum.

I dont know a whole lot about the "Custom" "Pulling" world but what would be the benefit of using this instead of an OEM kohler part?

Seems like a waste of effort & time if OEM is still available?

I need to divert oil from getting on the left front tire. Currently blows out of there under load. i will take the breather apart, but want a garantee it wont do it any more before installing new tires.

Well, I like the "hot rod" look so I added the part.  I liked the idea of routing vapors under the tractor to keep it clean and it did work for me.

Back in my go-kart racing days with no-governor Briggs 5 HP engines we would just use a piece of 1/4" aluminum plate with the same brass fitting. A hose was attached to that fitting to a small catch can.

Pics in this thread of the breather installed on the KillerKohler K301 I started for the 312 that will find its way into the 120.
