[AT] Gearbox breather plug

[charlie hill]

Another option,  get a male pipe nipple maybe 2" long.
Stuff it with stainless steel or brass wool as others have 
suggested.  Put a pipe cap on it.  Either drill through the side
of the cap or through the nipple just under where the cap
tightens down.

Subject: [AT] Gearbox breather plug 

Hi all, I have JD 513 rotary mower, and am getting set to cut my fields 
while we have a dry spell. When I first bought the mower, the oil was 
milky, so I changed it, and it ran fine for the next 3 years.  Today, I 
checked the oil, and the level was fine, but it was milky again. It's 
either been stored under cover, or had a 5 gallon plastic pail over the 
gearbox. I noticed one thing in particular tonight, and that is the 
gearbox is not vented. Neither the fill or the check plugs have breather 
holes in them. I bought this at an auction so the previous history is 
unknown, but I was under the impression that all gearboxes needed a way 
to vent. I'm not losing oil through any seals at this point, so that is 
good. Any thoughts would be appreciated.

Thanks,
Mike M
