Quick change valve

[Mr Hogg Willetts]

Hi, I have quick change oil valve on my Troy bilt Pony 2020.
I changed the oil yesterday. I drained it after mowing on a hot mower. the lawnmower shop owner had given me the wrong filter. It spun on but was slightly larger for a Kawasaki. I didn't realize until it was all apart.

Anyway, he had to order the right one. I re-changed the oil last night. First off, I had trouble pulling that yellow plastic valve out the second time around after turning it and getting it out of the detente. It seemed really tight to pull out. I pulled harder and it pulled out too far, making a nice mess. The little nipple on the metal part that guides through the plastic to lock it came through the factory slit. (The Part closest to the motor.
I pushed it back on and cleaned up changes the oil etc.
my question is how can I make that plastic part a little easier to pull. I cleaned it up with a toothbrush. Is the plastic part replaceable on its own? I read a Thread on here that a Said you can remove that plastic piece to tighten the actual metal valve down.

Does anyone have one of these things disassembled . I am trying to picture how this functions internally.

If I was you and had removed the entire drain valve, I would replace it with a drain hose and not that twist and pull valve that is known to unscrew from the engine, break off and come apart, either way I have seen more than one of those valves cause unexpected sudden engine disassembly.

I did not remove the entire fitting, the plastic part came too far forward when pulling it. The metal tit so to speak passed the cut in the yellow part momentarily. I pushed it back and it's fine. I get i can change this to something else, but I'm asking about thw function of this piece as stated above.

The plastic piece just has 2 o-rings internally that seal the oil in, when you pull it forward the Orings no longer block the drain hole.
I'd advise replacing it like Ilengine said. Theyre a pain to deal with and can cause you alot of financial pain when you have to buy a new mower or engine.

What stops it from pulling too far forward when pulling it

There is no hard stop to prevent pulling the thing apart again. And you will be tightening the threaded portion everytime you service the mower.

the Interface between the mower and unit has never been loose or leaked. Mine made a mess when I pulled to hard when . The plastic piece wouldn't pull forward at first and then I pulled it too far forward.and it leaked I'm guessing between the bottom of the plastic and metal from being pulled too far forward.

There's a notch in the plastic that catches on a small bump on the metal part of it, but it's easily pulled over it.

You can take a small chisel and hammer and carefully tighten the metal threaded portion into the engine block. Many drains are loose that I change the oil on for customers.

I have had several over the years that you couldn't tighten the drain due to the flats hitting the frame below the engine. Have to remove engine to tighten the twist and pull drains.
