Unknown atv (gy6 150) rear reverse gear box fluid/grease/sludge?
Hey there all so I picked up a super cheap Chinese ATV (obviously) with a gy6 150, the engine looks nothing like the newer gy6’s so I would put it at probably 10-15 years old, no idea what brand it is but anyways.
was going through changing all the fluids when I get to the rear hub/reverse gear box. I go to change the “fluid” in it expecting gear oil and I get the bolt out, nothing happens, I think well **** it’s dry, when all of a sudden it starts slowly pooping out this greenish, what I can only describe as) sludge.
I’m guessing because it’s open vented it was at one time gear oil and now the moisture has killed it and turned it to a sludge, I wasn’t sure if it’s grease or not though or if it is intact gear oil so I’m hoping maybe someone here can help or atleast convince me to get it out and just put gear oil in it lol. Pictures for assistance
This is the reverse hub/gearbox
This is the sludge

Alright sounds good, any suggestions on how much to fill it? The drain plug is on top so it’s hard to tell as it’s not a fill until it drains out plug. It’s vented to the atmosphere though so if I put too much in will it really matter?

Yes i did, I drained out the “sludge” from the drain hold on the bottom of the gearbox, ran some clean gear fluid through it (literally just poured it through it trying to rinse out some of the stuff)
then refilled it to above the gears I believe? Just kinda winged it. Drove it for a bit (maybe a few miles worth) then drained and refilled again while hot
just used gear fluid from WalMart w75-90 weight or there abouts

Found unit
Maybe this will help, I am working on a FUSHIN 150 with this axle. Trying to find a cable to connect to shift lever. I found this site showing that axle, don't know if it will help anyone but here it is: https://www.scootercatalog.com/atv-r...e-reverse.html
