Filling a modified Tuff Torq K46 / T40 transaxle while ON the mower (Oil Fill Mod Series Video 3)

FINALLY we can change the oil on a K46 / T40 transaxle without having to take it off of the lawn mower! This video shows mounting a modified transaxle and external expansion tank. We use a cheap marine lower unit pump to fill the trans with oil, using a clever trick to prevent the oil from spilling out of the drain plug hole while we unscrew the pump and replace the drain plug.

Update: I checked the oil level in the expansion tank before and after mowing. The level in the tank went up about a quarter inch when the oil was hot. This was with the outdoor temperature at about 65 degrees F + mowing for an hour. FYI @billmolzon7723 since you asked.

Just an FYI, it's easier to drill a 1/4" hole first (the same size as the hole saw pilot) or just loosen the set screw on the pilot drill & pull it out a little further. Neat mod. I've rebuilt a couple of these & actually replaced mine with a K57, world of difference. Nice to see the mods, great tool to help others! Mobil 1 worked well for me. The worst of this, is John Deere is well aware of this issue & does nothing about it.

@tomgia1964

Cool , how did you get the drain plug in there? Did you drill it and thread it?

@user-yd3en3vt4c

I am in the middle of this mod. Wanted your thoughts and opinion on not using the expansion tank. The original expansion plug is only held in by the compression of the rubber. That original plug happens to fit on the end of the 1/2" tubing you used just as tight as it did on the tans axle originally. I am considering just using about 12 - 16" of the tubing with no tank. Just use the original vent plug on the end of a piece of clear tubing that I can see the oil level through. I plan on draining and filling the unit from the bottom anyway. The expansion tank I assume is for both a vent (which is built into cap) and also expansion of any fluids. I think that amount of tubing would allow for enough expansion. I could allows go back with a tank if it didn't work out. I could drill a hole somewhere and jut put enough tubing to go through opening and then insert original vent plug.

You're using the Mobil 1 5W-50 in place of the Tuff Torq oil? Did it work alright?

A friendly heads up - nice detailed video. Good copy and good video. After seeing your video last night, I looked at another K46 videos and read this reply “You overfilled it. The oil level is supposed to be 22-25mm (7/8") from the top edge.”
