Bobcat hydrostatic drive motor fluid

Im changing the hydrostatic drive motor fluid in my Bobcat T66. On the R series Bobcat this maintenance is done every 500 hours or every 12 months. This service and fluid is the same for Bobcat Track Loaders T450, T550, T590, T595, T650, T62, T64, T66, & T76.

Thanks for doing this video.
On my 2015 T650 the book says to put in 12.7 OZ. per side.
So I'll be getting 3 bottles.
Bobcat West cost is $15.17 per. this is in WA state.

I've got the T76. The manual says to let the entire contents of the bottle into the drive motor. My dealer swears that it is supposed to be half (6 ounces) in one motor and half in the other. Based on your video, it surely looks like there is more than 6 ounces that came out of there and I would not interpret empty the entire contents of one bottle into the drive motor as put half in one motor and the other half in the other. I think they are wrong, but I cannot seem to find the definitive answer. Do you know the size in ounces of the jar you used to collect the old oil?

Bobcat is notorious for hiding what kinds of fluids they use. Even the older Bobs like mine recommended a special hydraulic oil that is massively overpriced. I use the regular 68 hydraulic oil for the old Bobs and never had a problem. Wonder what kind of special sauce is in that oil you put in.

I'm on the fence with brands i am looking at a t66 what are your thoughts since you own one. i would be using it for farm use.
