JoeM 9,861 #2 Posted 2 hours ago If the machine has the Eaton 11 (has a spin on oil filter on the left side under the seat pan) the drain plug is the main plug located under the rear housing and requires a 1/4" hex wrench. If it has the Eaton 7, (no oil filter) This transmission has two separate oil compartments. One is the hydro (10w-30 oil) that is dedicated to hydro pump and is captive. The other is rear gearing lubrication. Takes 80w-90 and drains from the main plug located under the rear housing and requires a 1/4" hex wrench. The Eaton 7 hydro system can be drained and refilled. The drain plug is an o-ring plug located under the pump unit on the right side. 1 Share this post Link to post Share on other sites
