New drain plug design

[StarTech]

Just came across a new drain plug design on a KT725. Still a 3/8 NPT plug but they now have a T50 torx countersink and not the normal Square drive. Customer just recently purchase a Cub Cadet ZTR with it. Customer was wanting to know how to get it out and I had go onsite to see was up with the drain. Glad he was close by. At least his was on the money and I had a Torx set with me.

Should had been a hose installed as oil would go over the place. Having the customer bring the mower so I can extract the oil and install a drain hose so he can change his own oil without making a huge mess. Mower engine is setup for the hose just CC was too cheap to install a hose.

Good! Despite a drain extension, my CH22 still drains onto the frame and linkages on my tractor. Post a pic when you can, please. Old saying: "In public forums, if no picture, it does not exist." {Although AI is making verification of stuff harder ...}

And most websites are too lazy to even post an image of the part. PN 25 139 62-S

Thank the product engineers and folks at the EPA who are trying to prevent waste oil from just being poured out on the ground or dumped into a water drainage system. Some people just want it gone and don't care who they hurt in the long term.

The harder they make it for DIY folks, the more they prevent issues and steer them towards the shops with proper disposal capabilities.

Irresponsible waste oil disposal is a bigger problem than most people realize.

Of course, when I grew up in the 60's they used tanker trucks to spray waste oil on the country dirt roads to keep the dust down or people would pour it on tree stumps so they could burn them out easier at a later time. Very little thought was given to some of this waste oil eventually finding its way into ground water.

No, I'm not a "tree hugger", but I do believe in being responsible when it comes to waste oil/ anti-freeze or battery recycling.

Yup. Fortunately, Walmarts with auto centers take up to 5 gallons of used oils per day for free here. Elsewhere too?

I think the quick oil change places do too. One here takes, at least formerly did, used antifreeze too -- the other big offender from DIYs.

The county's hazardous waste facility here takes all, including used brake fluid, paint, etc., but is a longer drive and by appointment (days in advance) only.

As just mention there is no reason other than pure d laziness on not recycle the oil. I got 4 gallon sitting in the bed of my truck right now where I just emptied my oil extractor. Will drop it off the next trip to town.

Fumoto makes a wonderful oil drain valve for most every application.

My Kawasaki came with a plastic petcock with 10mm plastic ”nut” to open. A nipple for 1/2” vinyl hose exits at right angle. This assembly is much cursed for the o-ring leaking but I think if not closed too tight and crushed it works fine.

The Kawasaki's 49116-0714 seems to be fine for consumer applications but for commercial users they tend to leak due heat damage. Another problem is not the small o-ring in the drain but is the large o-ring @ the M20 fitting which is a 15.8 id x 2.4 wide o-ring. Heat and oil resistance is important here.

Getting the double D nut tight is one of the problems; unless, you make a special tool for doing this while the engine is still mounted. Otherwise is the loosen of the engine to tighten it. Now replacing the o-ring does require loosening the engine or part of the tube end must cut off on most mowers so you remove and install the drain valve assy.

Now an option is to replace drain valve with a drain hose. The engine side of the hose need to be threaded at M20-2.50.

I used a Crow foot 1" socket to tighten mine. No engine loosening.

Utility knife cut off drain nipple quickly.
