2086 Transmission fluid change.
 

It’s time to change the transmission/diff fluid on my newly acquired 2086. I’ve searched for owners manuals but haven’t found anything that shows how to change the fluid and filter. Just looking for a little guidance to ensure I have all my ducks in a row.

Thanks!
Kyle.

Thanks for the response! I’ve found that page in the past. I’m sure it’s user error but I can’t see where it tells me anything beyond

“Hydrostatic with infinite forward and reverse”

I was trying to find a “how to video” on the YouTube to no avail.

Even a “here’s the drain, here’s the fill, here’s how to check fluid level” doesn’t seem to be in the owners manual.

Thanks for the help!
Kyle.

I looked in the 2086 Owners Manual. Yup, kinda vague.

The 2086 has the traditional Sundstrand Transmission. Thus, the procedures would be the same as prior tractors.

(A) Remove the Rear End cover and be prepared to collect ~7 quarts of oil.
(B) Clean the rear end cavity out as best as you can with your favorite cleaner. Blow out any residue.
(C) Remove the Hydro Oil Filter (automotive screw on type)
(D) Acquire a 921-3015 Rear End Gasket, 923-3014 Oil Filter, and 2 gallons of Hydro Oil (ie: Hytran).
Install new gasket and button up rear end. Install new filter. Then install new oil.

:ThumbsUp:

Roland is correct. If you have the rear PTO option, it is a real pain to pull the rear cover. :angry:

Not many 2086's around please post some pics if you have them. Was the cam gear replaced yet?

Thanks Roland!

Now the $2.00 question....... where do I fill it?! Do I just measure 7 quarts and hope I got it right? Or is it like a standard car diff? Fill until it comes out of fill
hole?

Got all the parts ready, just terrified I’ll pull the wrong plug to fill with!


Thanks!
Kyle.

(I know this is probably very self explanatory, I have a feeling I’ve overthought this and got myself stuck in a mental cardboard box)

Give me a chance to get this site figured out and how to post pics!

Previous owner didn’t know the history very well. So my safe assumption is the cam gear is still plastic.

Cheers!

Lift up your seat. The "dipstick" is visible. Dump 6 quarts in and then fill until
the indicator on the dipstick says it's full.

There's nothing wrong with asking questions, if there was, then there wouldn't be much point in this forum! We're here to help :beerchug:

The rear axles on the Cubs do not have a dedicated drain plug. In order to drain the transaxle you need to completely remove the rear plate on the back of the transmission case. You will most likely need a new gasket for the plate. Once fluid is drained, make sure the case is clean internally, and then bolt the cover and new gasket back up. There's a fill on top, fill it to the 'full' mark.

Don't forget about the filter, though! It's on the front of the transmission, underneath the frame. Pull it off with a filter wrench (some fluid will also come out so be careful of that) and replace it with a new filter. Be sure it is the CORRECT filter or fluid may not be able to flow through it. With the new filter installed, run the tractor for a few minutes to let the pump suck fluid into the filter, the level in the case will drop a bit. Add more fluid until the level is 'full' again, and you'll be good to go.

Roland, thank you sir! I’ve always done better with the picture books.

CubCadet_107, you just brought the whole process together for me, thank you so much.

You guys are awesome and I truly appreciate the quick responses.

Time to go get dirty....

The 2086 has a drain plug. It's at the bottom of the case in front next to the suction tube.

And here comes Sam with the Hail Mary throw.

Thank you.

Just wanted to update this and say thank you to everyone you provided answers. Got all the fluids changed out and have been cutting away. Thanks again.
