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.
