You have DF250s so I can't say for sure yours looks like my DF200s
so, as I said in the first post of this thread...
"Zukes have an "extra" gear oil "vent" hole above the Oil Level hole. This actually allows you to fill from the Oil Level hole. We are all used to pumping up from the Drain hole.
This year I learned that I can, in fact, ditch the pump and just squeeze the bottle into the Oil Level hole. "
There is nothing marked "fill". From highest to lowest, there is "Oil"(this is the air vent), "Oil level" and there is an unlabeled "drain" at the bottom.
You can't put oil in thru the vent. I tried it that way, with the Level open, and it leaked right out of the Level hole.
With the Vent open and the drain plugged, you CAN put oil in the Oil Level. I used a pump on the first motor. It will take
almost all of a quart before it comes out the higher VENT.
Then you remove the pump and let it dribble out the Level hole and put the Level plug in.
On the second motor, with Vent open, I ditched the pump and used the cut pointy top of the gear oil bottle and squeezed it into the Oil Level. Because there is a higher vent, it fills right up to the level hole. Depending on whether the pointy nozzle is tight in the hole, it will overflow out the vent when full. Same amount as before. Basically the whole quart.
The book would have you leave the level closed, vent open, and pump
up from the drain til it comes out of the vent. then close the vent and remove the pump and close the drain. Then open the oil level and make sure it dribbles out...showing that you are at the level.
I did it that way my whole life. It is messy. The third hole makes the new way possible
Remember, the DRAIN plug is different. It has a magnet.
